The Solution Counts
Long gone are the times in which you could succeed on the
market by just selling goods. Today, you, our valued readers, rightly expect more from your supplier than simply the
delivery of components. The fact that Turck provides you
with this “more” is reflected in the current fiscal year, which,
despite the financial crisis and economic downswing, has
been extraordinarily successful. You have honored our
approach of comprehensively solving your automation
tasks with innovation and customer proximity, instead of
just supplying components.
Regardless of whether we are talking about the BL ident
RFID system, the new BL compact block I/O family or the
expansion of our portfolio with the addition of vision systems, all
these activities support our solution-oriented customer service. And
as a solution partner for its customers, Turck is increasingly thinking
in terms of solutions and systems, which is naturally reflected in our
product development.
Our success in this field is primarily characterized by targeted co­­
operation between our Systems Sales and Pre-Sales/Application
Support at the customers and flexibly implementing the requirements in product management, development and production. On
the technical side, the constant implementation of platform strategies in and among the various product families plays an important
role, especially in the fields of fieldbus, networks and I/O. In this environment, our engineering software, function and application libraries
as well as programmable units are also significant.
As a Turck customer, you benefit not only from CoDeSys programmable fieldbus gateways, a multitude of sub-networks plus I/O
functions and the FDT/DTM-based configurator I/O Assistant, but
also from our understanding of your specific application. With these
ingredients, we combine fieldbus technology, sensors and actuators
to create your complete tailor-made solution.

Double-Digit
Growth
 For 2008 Turck is once again
expecting double-digit growth. As
Managing Director Christian Wolf
announced during a press conference that the family-owned and
operated company is expecting consolidated group sales to increase by
more than 11 percent to about 370
million euros. The total number of
employees in all 27 locations grew
by more than 8 percent to 2,830. At
its locations throughout Germany,
which include the Mülheim an der
Ruhr, Halver and Beierfeld plants,
Turck employs about 1,430 workers
– of those, 55 are trainees. “Despite
the current crisis in the world economy, the Turck Group was able to achieve double-digit sales increases for
the seventh consecutive year,” says
Wolf. “The result shows that Turck’s
strategy of positioning itself as a
customer solution partner through
innovation and customer proximity
has been successful – regardless of
whether we are referring to the BL
ident RFID System, the new BL compact block I/O family or the expansion
of our portfolio with the addition of
vision systems.”

Magnetic Field Sensors with
200 mm Measuring Range
 WIM200 is Turck’s new magnetic field sensor with a 200 mm measuring
range. Even with these measuring lengths, the sensor provides particularly
high linearity and precision in extremely short blind zones. This means the
WIM200 in the new Q25 housing is ideal for applications that require the
exact signal sequences across a larger measuring range – for example, in
pneumatically-driven pump equipment, disks, presses or punches. The
appropriate assembly accessories are available to the user for easily adapting
to as many applications as possible. For example, float queries to the flow
rate measuring devices or level monitoring systems can be implemented into
process control systems in a simple, but effective way. The sensor can also
be used for position detection on suitable pneumatic cylinders. With an external magnet as a
position sensor, other applications can also be
individually implemented. The WIM200 is a
cost efficient alternative to other linear
path sensors that are over-dimensioned in many applications.
Fully Metal Ultrasound
 Turck recently introduced the world’s first fully metal
ultrasonic sensor. The fully encapsulated M25U, developed by
the Turck partner Banner Engineering, is completely enclosed in
stainless steel – including both the housing and sonic converter
face – and complies with degrees of protection IP68/IP69K. Thus
the ultrasonic barrier sensor, consisting of both transmitter and
receiver, is particularly suitable for detecting bottles and containers in aseptic applications,
such as bottling operations in H2O2 atmospheres.
The M25U fully meets all
demands relating to hygienic design in the beverage,
food and pharmaceutical
industries. The stainless
steel enclosure is not just
resistant to chemicals
and aggressive cleaning
agents, but is also resistant
to temperature shocks.

Turck Strengthens
Its Management
Ethernet Gateways
 Ethernet-compatible gateways with an integrated switch are available immediately as an additional feature for the BL20 I/O system. With the compact and inexpensive BL20 Ethernet gateways, Turck is supporting the trend toward decentralization
and is facilitating flexible control solutions even in limited spaces. Economy gateways
can be easily integrated into existing communications structures via the standard
Ethernet, because the Ethernet is already integrated as a native and inexpensive
interface into most control systems, from the PC to the touch panel. Furthermore, the
new BL20 gateways represent the most inexpensive remote I/O solution for the IP20
degree of protection currently on the market. Just 33 mm wide, the gateways have a
power supply unit as well as a switch on board, making them easier to install. They are
also equipped with two RJ45 ports and support conventional Ethernet bus protocols
Modbus TCP and Ethernet/IP.
Highest Switching
Distances
 With the models EG08, Q08
and Q80 models, Turck is offering three new uprox+ Factor1
sensors with each of the largest
measured switching distances
in their respective designs. The
threaded pipe sensors in the
EG08 series can be flush mounted
and reliably detect the pres­ence
of metal objects starting at a
distance of 3 mm. The measured switching distance of the
only 8 mm high Q08 sensors
has risen to 12 mm for non-flush
mounting. The square-shaped
Q80 models provide the highest switching distances – up to
80 mm. Thanks to predamping protection, both the Q08 plastic sensors and the Q80 models can be mounted directly on metal. Due to
their low profile, the EG08 and the Q08 series are ideally suited for
applications with space limitations, regardless of whether in the food
or packaging industry.

2-Wire and
Namur Sensors
 Turck expanded its BIM-UNT
magnetic field sensor family for position detection of pneumatic cylinders. Besides a two-wire model, a
digital Namur version is now avail­
able for use in explosion-protected
gas zones. This means Turck is one
of the few manufacturers that offers
Namur sensors also for T Nut cylinders. BIM-UNT sensors can detect
all magnets in any conventional
pneumatic cylinders without multi­
ple slot switching points so that an
inventory of different sensor types
for different cylinders is no longer
necessary.

Turck Now with
Vision Systems
 In view of its strategic evoluti­
on as a solution provider, the sensor,
fieldbus, interface and connectivi­
ty specialist Turck has added vision
systems to its product portfolio. Since
October, Banner Engineering vision
systems have been available in
Germany through the Turck’s sales
organisation. Photoelectric sensors
and personnel safety systems have
long been sold by Turck, while vision
systems were sold directly by the Ger­
man Banner subsidiary, which will be
merged into the Turck sales organiza­
tion. By adding vision systems to the
product port­folio, Turck is once again
confirming its position as a provider of
both single components and comple­
te solutions for its applications. The
new products are not only rounding
off the modular BL ident RFID pac­
kage with vision systems, but are also
opening up new areas of application,
such as quality assurance. True to our
motto: “Sense it – Connect it – Bus it
– Solve it.”
Factor 1 for Stacking
 Turck has developed a new uprox+ sensor in the Q10S design for
the assembly and materials handling industry. The compact Factor 1 sen­
sor, with the dimensions 10 x 10 x 28 mm, has the same high switching
distances on all metals and offers many degrees of freedom when it comes
to assembly. This means the sensors from this series can be mounted on
metal using an intermediate plate made of metal, even directly next to one
another. The Q10S achieves a switching distance of 5 mm for flush and
partially flush assembly. In the case of fully flush mounting, the switching
distance is reduced to 2.3 mm with the same reliable operation so that an
additional flush version becomes redundant. The new Q10S sensors are
currently available both with PUR cable as well as a pigtail variant with M8x1
plug-in connectors. The housing consists of chemically resistant and
mechanically
robust polypropy­
lenes. The sensor
operates in a tem­
perature range of
-30°C...+85°C.
Diagnostic Power Conditioner System for FF
 DPC-49-DU is Turck's latest addition to its Diagnostic Power Conditio­
ner family for Foundation Fieldbus. To ensure system integrity, the Diagnos­
tic Unit of the DU version offers the same functionality as the ADU model
(Advanced Diagnostic Unit) introduced last year, which also permits phys­
ical layer and protocol diagnosis. The Diagnostic Power Conditioner has
an integrated diagnosis unit that can discover
the system disruptions, for example, in one of
the voltage supply modules. The device dis­
plays the diagnosis via a potential-free relay
contact. The DPC system permits efficient
segment planning and feeds FF segments
redundantly, each with a maximum of 800mA
output current and 30 VDC output voltage.
With this performance data, the Power Con­
ditioner itself can supply long distance seg­
ments with numerous subscribers with no
problem at all.

Management PA
Specialists for Granulates
 Turck has launched the BCC sensor series especially for the level measurement of
plastic granulates. The BCC capacitive sensors can detect even the smallest grain sizes.
In addition, they offer a high EMC protection and are particularly insensitive to electro­
static discharge (ESD). This is a frequent problem that causes sensor failure with plastic
granulates in pipe systems and silos. Another challenge in the level measuring of plastic
granulate is mounting in metal flanges, which prevents unrestricted detection and the
fault-free operation of the electronics, since the lateral predamping drastically reduces
the switching distance. The BCC sensors are also able to effectively switch off this dis­
ruptive effect using a lateral screen and an integrated analysis unit.
Safety Controller
 Turck's new SC22-3 safety
controller is an efficient solu­tion
for connecting several safety
devices to machine controls.
The controller, developed by
partner Banner Engineering,
eliminates the need for several dedi­
cated safety relays and integrates
input devices such as emergency
stop switches, light screens, twohand controls, interlocking switches
or safety mats in the machine con­
trol. A total of 22 contact-based
and PNP solid-state inputs can be
monitored so that a broad range of
input types for safety and non-safety
devices can be covered. Each input can be assigned to one of
the three dual-channel safety outputs. A combination of LCD
display and status LEDs provides the user with information at
any time about power supply, error states, output status and
communication with the PC.
 Ryan Kromhout has assumed
overall responsibility for product
management in the process auto­
mation division. The 35-year-old
previously worked as a product
manager for Interface technology
for the Germany-based automation
specialist. Before
transferring to Turck,
Kromhout worked for
a well-known process
automation company
in sales and market­
ing positions.
Frank Rohn, who was
recently manager of
product manage­
ment in the personnel Ryan Kromhout
union and of sales in
the field of process automation, has
assumed the sales and marketing
responsibility across a broad range
of fields. Rohn is also responsible
for PA sales for all outside European
markets, except China and the USA.
The sales regions in Germany and
Europe and worldwide sales in the
factory automation business division
will now be headed up by Christoph
Zöller.
Robust Cable
 Turck has expanded its cable
product line for the BIM-UNT sen­
sor family for detecting the position
of pneumatic cylinders. In addition
to the standard PUR cable which is
particularly suitable for applications
with E-chains and resistant to oils
and cooling lubricants, Turck now
offers a heat-resistant, food safe and
chemically resistant cable for the
sensors. The halogen-free, crosslinked by radiation, flame-resistant
and touch-heat resistant cable is suit­
able for use in the welding industry.
For applications in which chemical
resistance, certification for food appli­
cations or special temperature sta­
bility is required, Turck is offering the
cable quality S1165 (TPE).

BL compact allows
customized signal
combinations for
a multitude of I/O
tasks
Tailor-Made
Rugged I/O block modules from the new BL compact
series offer a variety of I/Os in a compact housing
0

 Quick read
I/O systems are increasingly being installed outside the control
cabinet and in direct proximity to sensors and actuators, which
demands that they be rugged, efficient and user-friendly. With
the new BL compact Block I/Os, Turck is supporting this trend
and adding flexible Block I/Os for analog and digital signals to
its IP67 product line. These combine the variety of the modular BL67 systems in a very small space in a completely sealed
housing.
T
he world of automation is evolving at
an increasingly faster pace; customerspecific applications – regardless of
whether machine manufacturing, production or
logistics – are becoming more complex and challenging. Those seeking cost-effective integration of machines cannot ignore flexible solutions
that allow workpiece or workflow changes at a
low cost and with short retrofitting times, which
in fact increase machine capacity. Sensor, connection and fieldbus solutions used should not be
pushed to the back of the queue. With its new
field-proven I/O solutions, Turck is now responding to the growing trend of bringing together as
many varied applications as possible with the
most cost-efficient automation strategies.
Large variety, small package
Based on its tried-and-true modular BL67 I/O
systems, the automation specialist is launching a new series of rugged I/O modules: the BL
compact fieldbus family. In doing so, Turck is
using its existing BL67 I/O portfolio and combining the electronics from different BL67 modules, including gateways, in a unique housing.
The compact stations combine connections for
up to 16 digital or analog input signals, regardless of whether they are simple, discrete signals
or special applications such as RFID, with distinctive monitoring and diagnosis functions. The

fieldbus modules initially available for Profibus DP
and DeviceNet allow end users to reach the next
step towards decentralized automation – and to do
so cost effectively. Even under tough electrical and
mechanical conditions, these modules can be connected directly to the machine in a rugged industrial
environment.
While Turck’s BL67 – consisting of a gateway
and stackable I/O modules – continues to offer an
unbeatable variety of signal combinations and fieldbus interfaces, BL compact can be mounted where
limited space is available. A BL67 station can be
used to process many different signals, but requires
more space for mounting than BL compact. If
only a small number of specific signal combinations needs to be processed, BL compact’s limited
space requirements and simple assembly provide a
viable alternative.
The plastic housing of the BL compact series is
completely sealed with epoxy resin and meets the
requirements of the IP67 protection class. It is initially available in three sizes each with varying connection profiles. Alternatively, it can be equipped with
M8, M12, or M16 metal plug-in connectors for the
full plug-and-play functionality, control for on-site
diagnosis and rotary encoding switches for simple
address setting. Thus, the I/O modules offer a new
degree of application compatibility in the market of
compact fieldbus solutions.
Increased flexibility, low configuration
costs
The BL compact series is strategically positioned
between the reliable modular stations of the BL67
series and the compact fieldbus modules (FLDP,
FDN) from the Turck portfolio. It combines the advantages of modularity with the benefits of cost, installation and low maintenance modules in a new decentralized concept. Market-oriented connection combinations (XSG-PD, analog inputs/outputs, RS232, RS
485, SSI or RFID) and, on request, poss­ible special
customer solutions allow end users a high level of
flexibility even at low levels of expansion in supply
chain management – regardless of whether in the
machine manufacturing, automobile, packaging or
food industries.
Thanks to its coherent modular concept, Turck
has integrated the complexity of hybrid fieldbus solutions normally handled by the customer into its own
production processes. The customer now receives a
tailor-made solution right off the rack at a competitive
price. In addition to the procurement costs, the BL
compact solution can provide impress with further
savings in processing costs. Compared to hybrid
fieldbus systems, storage is easier because space
no longer has to be reserved for each individual I/O
module, including the gateway. Furthermore, a module that is precisely tailored to the application can
be installed without engineering or assembly work,
which above all results in a time advantage particularly with the use of numerous fieldbus stations. The
use of new modules will pay off anywhere that new
I/Os are to be integrated into existing control system
solutions in the foreseeable future.
26 variations to start with
The Profibus DP and DeviceNet bus protocols used
most often in production automation will initially
support 26 different housing and connection configurations at the time of market launch in November. In the future, Turck will offer CANopen and Ethernet-based I/O solutions (Modbus/TCP and EtherNet/IP) in this design. Due to the modular concept,
the customer can also have tailor-made I/O block

modules assembled. And should the market require
certain module combinations that are not yet part
of the portfolio, Turck can assemble these in just a
few weeks.
Even intelligent actuators and sensors, such
as valve clusters or optical sensors via an I/O link
interface, will be installed in the future using BL
compact. With the inclusion of this interface in the
BL compact product family, Turck is not only rounding off its comprehensive fieldbus portfolio, but also
highlighting its claim as a competent solution partner that offers its customers complete automation
strategies. From a multitude of pressure, ultrasound
or temperature sensors to flexible interface modules

from the BL compact series, end users can rely on
complete I/O link solutions from Turck.
Summary
With the BL compact rugged I/O block module
series, Turck has created an easy-to-install lowmaintenance fieldbus solution that allows users to
fully exploit newly emerging automation potentials in
rugged industrial environments and to increase their
machine capacity based on highly compatible and
simple to integrate I/O stations.

Mr Wolf, Turck was founded in the
sixties. What does Turck stand for
today?
Turck has transformed itself from a conventional supplier of sensor components to a
supplier of complete automation solutions.
Our business is not only to understand the
single application, but also the automation
environment. This in turn enables us to
reduce the “time” factor for the customer.
For this you need to understand the automation periphery, you need to know which
control tasks are required by the customer
and how these have to be networked. We
see ourselves as solution partners for our
customers, both in factory and in process
automation, because we offer complete
signal processing solutions.
Christian Wolf
promises Turck
customers
more time for
the essentials
Which products provide the actual
solutions?
In factory automation, our range of products covers the fields of sensor, fieldbus
and connection technology, right up to
complete solutions such as RFID, which
are also available with compact controllers
in the form of programmable gateways.
In process automation, we are developing the links between control systems
and field devices in all their variants, from
point-to-point, to point-to-bus, right up
to bus-to-bus processing, i.e. interface,
remote I/O and fieldbus technology. In
addition to interface technology, such as
isolating switching amplifiers or analog
data transmitters, Turck offers remote
I/O systems for zones 1 and 2, as well as
fieldbus solutions for Profibus PA, Foundation Fieldbus, HSE and HART.
“
Understanding the
Automation Environment
”
KEM editor Denise Froehlich spoke with Christian Wolf,
Managing Director of the Turck Group, about the positioning
of the automation specialist company
The Turck Group has a very decentralized structure. Which areas are
the individual sites responsible for?
While Turck has a decentralized structure worldwide, it also has an integrated
system of management. At the same
time, every location is charged with a
high degree of individual responsibility:
The local management has a high degree
of self responsibility and utilizes control
mechanisms – always with the aim of
encouraging an entrepreneurial mindset
within the company. Each general manager is responsible for their own profit and
loss account. This decentralized structure is particularly important for overseas
companies, because these companies
best understand their respective markets.
The German management has the task of
implementing the overall strategy with the
general managers locally. In our view, it is
critical not to impose a global strategy on
13
national subsidiaries without taking local
requirements into account.
Doesn‘t this kind of division give
rise to lengthy decision processes? Is it still possible to respond
flexibly?
On the contrary. The decision is made
where it belongs, exactly on location. In this
respect, we follow the principles of a lean
organization: The individual general managers are free to act as required in the local
implementation of the strategy, even in key
areas. For example, it is not possible to
promote the fieldbus everywhere because
the degree of automation is not so strongly
developed in certain countries and regions.
In other markets and regions, sensor technology is subject to enormous price pressure, and customers require an all-round
automation partner from the start. This is
a requirement we have to meet in order to
make a quick return on investment.
Turck generates around 30 percent
of its sales in the automotive industry which is considered the “Rolls
Royce” of the automation sector.
How do you manage to be one of
the top suppliers?
The only way is by very close customer contact. One part of the business is standard,
for example conventional inductive M12
sensors, where large volumes are required.
However, the most exciting areas naturally
involve special applications on robots or on
the painting line where intricate tasks have
to be solved. With the automotive customer,
the distinction is between companies who
are development partners and those who
are just component suppliers.
RFID is a key area at Turck. According to your own statements, you
have made the most advances in
this field. What does this mean in
real terms and what are the future
trends?
Our RFID activities concentrate exclusively
on industrial applications. We have no
intention of penetrating the consumer sectors, but aim to focus on the automotive
industry, machine building, the packaging
industry and industrial logistics. For this we
have developed rugged components such
as tags, write/read heads and interface
devices which we have integrated directly
in a modular fieldbus system. This means
that the RFID processing is implemented
directly with a fieldbus coupler. This is
located on the fieldbus level in close proximity to the controller.
more @
2_2008
Right from the start, we have been able
to offer our high temperature tag for the
automotive industry, a product that previously never existed. This tag can even be
run through paint lines at temperatures up
to 210 degrees Celsius. Our RFID offering
began with the 13.56 Megahertz technology, and we are currently working with
UHF technology, as well as the 125 kHz
solutions, in order to round off our product portfolio. As far as write/read heads
are concerned, we are continuously offering new designs that are optimized for
applications, such as for roller conveyors.
We also offer a higher level of integration
in the existing automation environment.
Turck invests around 10 percent of
its sales in R&D. What are the other
challenges that you face?
We intend to gain a firmer foothold in the
field of pressure, temperature and flow
sensors, especially in the machine building sector. We also intend to make further developments in the field of linear
position sensors, and also in the field of
analog measuring. Bus technology allows
us to develop further as a solution supplier, penetrating the control technology
sector, as well as in the field of industrial
identification. IT and automation technology will continue to merge even further,
and this is something we must take into
account within our strategy. A high R&D
investment is very important for us. If you
want to maintain an innovation edge, you
have to remain one of the top 3 suppliers
in each market segment. We manufacture
around 70 percent of our products in Germany. If you are number 5 or 6 in the market, this is not very attractive and does not
guarantee double-digit annual growth. In
the USA, we are market leaders in inductive sensors and connectivity solutions. In
China, we are also market leaders in these
areas and are now already the number 2
in fieldbus technology. We need to expand
this further since this is where the largest
automation markets outside Europe are to
be found. The outcome of the struggles
for new markets, such as in Russia, India,
Brazil or the Middle East will be critical.
We have already taken a leading position
in Eastern Europe because we started at
a very early stage. However, it must also
be said that our aim to penetrate overseas
markets is also based on our intention
of strengthening our activities at home in
Germany.

President & CEO,
Turck USA
Turck has
transformed itself
in the USA from a
component supplier
to a competent
supplier of individual
automation solutions
Flexible production
“Essential success factors that played a role in our
company becoming a world market leader were and
are customer-specific solutions and fast delivery
times,” explains Dave Lagerstrom, Managing Director at Turck USA. “In terms of personnel and structure,
our organization is able to identify and solve at any time
and at short notice the special automation problem of
a customer – whether it has to do with standard components, individual product developments or specific
system solutions.” In order to make improvements in
this regard, the company has implemented a system
that facilitates the rapid development and modification of products. It enables company engineers to
develop up to 200 new solution variations within one
week.
Usually, the products are delivered to the customer within a week. With the short delivery times
and the multitude of individual product ideas and
system solutions, Turck has set itself apart from its
competitors. “In order to further increase our flexibility and speed on the market, we started up a modern extrusion coating plant in 2008,” says Guido
Frohnhaus, Vice President of Technology at Turck
USA Despite modern production machines, however, the key to success is still an efficient workforce,
because the majority of the products, especially in
the area of connection technology, can only be produced manually.
The entire production line is geared toward
being able to handle each project individually and to
meet market requirements. That is how Turck customers have the opportunity – primarily with more
complex tasks – to have the solution proposals
from the system specialists adapted to their
respective applications directly at the factory without having to involve another supplier. This eliminates one step in the supply
chain and facilitates fast, more reliable and cost
effective solutions.
In most other countries, the company’s sales
offices are set up for direct sales, however the US
sales office had to be structured differently due to the
size of the country. It also benefits from the application know-how and the solution competency of the
specialists in Minneapolis. That is why the Turck sales
office in the USA decided early on to work together

Manual work with
computer support:
The expert interplay
between human and
technology is the key
to success on the
American market
with a dense network of distribution partners. Thousands of independent sales partners hit the road
every day to introduce the right solutions to potential customers. That is how sales representatives
become familiar with the customer’s applications on
site, which makes it possible to offer just the right
products and solutions that the customer is looking
for. The sales representatives have the opportunity
at any time to ask the Turck product managers for
advice if it's about finding the right configuration for
a project. “The technical competence of our product
specialists goes far beyond simple product knowledge,” says Lagerstrom. “They make process flows
clear and can support customers and sales when it
comes to considering an application in its entirety.
This is invaluable when looking for the right solutions
and represents incomparable added value for the
customer.”

In Turck’s
BL ident RFID
system, interference-free HF
and far-ranging
UHF technology
can be used
simultaneously
Freedom of Choice
The expanded BL ident RFID system permits customized
identification solutions for production and logistics processes
19
W
hile RFID has been used in industrial
production in only a number of systems
over the last two decades, today, the
contact-free identification technology has become
more and more of a standard in production technology. The development of different technologies
and standards has contributed to this increase considerably. In the beginning, in addition to proprietary solutions (frequencies around 1.5 MHz), only
systems with 125 or 250 kHz were used as the open
standard. However, users are now spoiled for choice
between numerous frequencies. Each has its specific strengths for certain applications.
Production example: In the candy machines from Winkler and Dünnebier,
RFID guarantees that there is an overview of all forms used at all times
Different frequency ranges
The single standard frequencies – the only ones
for years - in the range of 125 and 250 kHz were
most familiar to manufacturers because almost every
inductive sensor had been working in this frequency range for decades. The limited selection made
it easy for many users to make the “right” choice,
even if compromises were necessary in the process. Today, RFID systems function in a range from
125 kHz to 13.56 and 433 MHz - even up to 5.8
GHz in accordance to the most varying standards.
This makes selecting RFID much more difficult and
requires considerable technical expertise. All of these
variations are justified – depending on the respective application. For the right selection, the user or
system integrator should take a close look at the
application in order to decide which system is the
right one. Depending on the frequency, there are different criteria that have to be observed.
First of all, if you take a look at the ratio between
the maximum transmission power permitted and
the possible disruptive factors, the decision lies in selecting high frequencies
in order to avoid possible mutual
influence. In this case, we are
referring to solutions in the
UHF range between 400 and
900 MHz, as well as in the
microwave range with 2.45
and 5.8 GHz. Depending on
the design, the high frequencies can permit ranges of up
to 100 m.
Long range has
limitations
In the case of many applications, however, high
frequencies lead to considerable difficulties. Therefore,
the higher the frequency, the more energy is absorbed
through the polar fluids, such as water (that is precisely why a microwave oven is ideal for heating up). This
means its use in the food and beverage production or better said, anywhere where moisture develops –
is considerably limited or even impossible.
Other problems could occur in a metal
environment. Here, the waves are reflected and

partially bundled so that the originally desired
data carrier card reader is shifted physically and
fragmented which can lead to incorrect readings due
to falsely addressed data carriers. Systems in the HF
range (13.56 MHz) are clearly advantageous in this
case. They may offer ranges of “only” a maximum
of 100 cm, however, they are largely insensitive to
moisture. The absorption of field energy through a
metallic environment does have an adverse effect on
these frequencies, but some designs, including the
one by Turck, provide data carriers that are equipped
with ferrite foils and can be mounted directly onto
the metal. Alternatively, it is sufficient to mount conventional data carriers with sufficient distance to the
metal (minimum 20 to 30 mm).
Systems in the 125 kHz range can be used particularly effectively in a metallic environment. Here,
there are even a few special designs that can be used
to read out and write the data carrier straight through
the metal. The disadvantage with these systems,
however, is the low fluctuation voltage distance

RFID systems offer many options for handling logistics and production
processes more efficiently – if the system is working in the frequency

at high temperatures in engine production, in autoclaves and on

because many emissions in
the industrial environment occur
in this frequency range. Thus, many
inductive sensors work with similar frequencies and with the same outputs, which
can lead to the stronger one winning out.
Another disadvantage of the LF systems is the
relatively low transmission rate. For fast applications
or so-called “on-the-fly” read and write operations, in
which the processes are executed in motion, these
systems can only be used to a very limited extent.
In order to be able to realize extremely short cycle
times and high processing speeds, the data carrier
must be wrote and read in the shortest time possible. For such applications, systems in the 13.56MHz
range are indispensable. Due to the higher frequency,
considerably more information can be modulated on
The designs show that the
selection of an appropriate
RFID system is not trivial for certain applications. If different requirements
are to be combined, up to now, the user frequently
had to be satisfied with compromises. With the current expansion of its BL ident RFID systems, Turck
is now offering the option of combining the benefits
of HF and the UHF technology into one system. The
kicker: An expensive configuration is not necessary for parallel operation; it is sufficient, for example, to connect a UHF reading head to an existing
HF system. The considerably increased range of up
to three meters expands the application spectrum
enormously. If BL ident has been primarily used
for production control, the large ranges and
the ability to detect groups now also permit its efficient use in distribution and
logistics, as well as in the entire supply chain management. At the SPS/
IPC/Drives trade show in Nuremberg,
Turck introduced the first two UHF
read heads, measuring 260 x 260
mm for ranges up to three meters,
as well as 80 x 80 mm for ranges up
to one meter.

The option of being able to use a second frequency, in addition to the 13.56 MHz frequency optimal for industrial production processes,

has been routinely expanded with application-specific modules that provide users with the solution to
their identification issues.
For example, in addition to standard data carriers for temperatures up to 120 °C, Turck data carriers are available for up to 210 °C. This means that
the data carriers can accompany a skid through the
oven during the paint baking phase in automobile
production. Additional special solutions are available for use in autoclaves. The screw-in data carriers
withstand the combination of heat, moisture and
pressure. Among the newest developments are the
FRAM data carriers with a memory of 8 kbyte, as
well as data carriers that can be mounted on metal.
BL ident provides an extensive selection of
standard read-write heads, ranging from a sensor
housing to application-specific solutions, like for use
in gravity roller conveyors. The Q80 fits precisely
in the space between the rollers of an 80 cm wide
standard roller conveyor. The Q80 can also handle
“group detection,” in other words, it is able to identify
numerous data carriers simultaneously.
The BL ident product family is based on the
modular I/O systems: BL67, BL compact and
BL20C, and consists of connection technology and
gateways in addition to data carriers and read-write heads. Thanks to its modular design, the RFID

system can be easily integrated into existing Turck
I/O solutions. Depending on the expansion phase,
two, four, six or eight channels are available. Fieldbus
interfaces are available for Profibus DP, DeviceNet,
EtherNet/IP, PROFINET I/O and Modbus TCP.
Compact control in gateway
As an expansion to the interface components, Turck
is offering programmable gateways. The compact
control systems can be programmed in accordance
to IEC 61131-3 with CoDeSys and support the growing demand for decentralized automation solutions.
The heart of the gateway is a 32-bit RISC processor
with 512 kbyte program memory, which processes
1,000 AWL commands in less than a millisecond. As
a programming interface, an RS232 interface is also
available in addition to the 10/100 Mbit Ethernet.
With its “intelligence,” the gateway relieves the
higher-level control system because the RFID communication can be entirely handled directly in the
gateway. The functional component necessary for
SPS (Proxy Ident Block) is listed on site in the programmable gateway. With the higher-level control
system, only the user data has to be replaced.

RFID, core competencies here include applications
with modern image processing and laser systems.
Modular assembly system
For a well-known customer from the semiconductor
industry, the specialists from Regensburg have developed an automated loading and unloading system for
the manufacturing of multi-chip modules. This system
links numerous wire bonders and simultaneously handles quality control of the bonded chip modules. The
machine has a modular design and consists of one loading and unloading module with three magazine handling
stations, transfer paths on the wire bonder, as well as
the transverse and reverse transport routes for the parts
carrier. Before handlers transfer the processed chip
modules to the good parts magazine, they are checked
for correct wiring using RFID and image processing.
A reject parts punch marks the defective parts with a
hole on a determined position.

Before making the decision to go with the BL ident
system, project engineer Markus Müller tested
numerous solutions from several suppliers. “I was
very excited at how stably the Turck system operated,” explains Müller. “The other systems had continual difficulties both with regard to connecting to
the controller, as well as with the stability.” One reason for the problems could have been the unusual
positioning of the data carrier directly in the metal of
the parts carrier. For stability reasons, it could only
be made of steel with a hardened surface.
“We have a metal contact between the parts carrier and the data carrier. This should not actually be
the case, but due to general construction conditions,
the data carrier could not be mounted on its own
nor positioned otherwise. And our tests showed that
the Turck system had no problem with this issue, it
functioned on the first go,” explains Müller happily.
Turck now offers special data carriers for installation
on or in metal. The system has now been working for
almost one year in double and triple shift operation
and there have not yet been any outages.
Documentation of the process steps
Gefasoft uses the RFID technology in order to document all process steps directly on the parts carrier.
The first read-write location is located on the outlet of
the loading machine. Here, the data carrier receives
information as to whether all designated components were successfully mounted and can be further
processed. If the four points in the parts carrier are
properly filled, the content of the data carrier is added so it includes the processing release. Information
concerning the successful or unsuccessful processing of each component is added on the following
processing stations. Finally, on the last RFID station, the data is exported and the individual parts are
forwarded by the operator either to the good parts
magazine or the reject parts punch, depending on
their classification on the data carrier. The production
data is archived per batch in a report file.
Summary
For its automated production systems, Gefasoft
searched for a stable RFID system that has a modular and expandable design and is easy to connect
to the control system. With BL ident from Turck, the
Regensburg specialists found a system that meets all
the requirements. BL ident was even able to master
the challenge of mounting the data carrier. For Harald
Grünbauer, reason enough to continue building on BL
ident. “With what we have experienced, we will also
use the RFID solution from Turck in our systems in the
future,” promises the CEO.

sion components, as well as doors and trunk lids,
mainly through welding. The facility has a production
capacity of 220,000 parts per year.
“We produce parts for about 700 cars that are
delivered to the Volvo facility every day,” says Luc
Willems, maintenance engineer at Tower Automotive.
“Our production is set up for minimum storage and
warehousing. We always have to have a sufficient
reserve of parts for a production period of 6 hours;
overall our warehouse can store a reserve for a
maximum of 18 hours.” The Volvo parts are transported by trucks that make about 70 deliveries per
day. In order to guarantee the necessary flexibility
and punctual “Just-in-Time” deliveries, the company must ensure that production runs reliably. To this
end, production is primarily automated using more
than 180 ABB robots.

High temperature challenge
Thanks to the Turck RFID system, Tower Automotive
was not only able to increase production at the same
cost, but also make it more reliable
RFID modules are integrated into the automation
network at Tower Automotive via the BL67 I/O system
with PROFIBUS gateway
After researching the market for suitable products,
the decision-makers at Tower Automotive went for
the BL ident RFID system from Turck, which can
withstand extreme temperatures of -40 to +210°C.
“In addition to temperature resistance, a deciding
factor for us was that BL ident is an open system
that can work independently of a PLC and was
developed particularly for industrial automation,”
comments Willems. BL ident works with a frequency
of 13.56 MHz. “This worldwide standard on a very
high, low-noise frequency fit perfectly in the concept
of the entire system.”
After negative experiences with the first
system, the Turck solution was thoroughly tested
in advance. “As part of the testing process, we
hung the tags for ten days in an oven at 180 °C.
Even after this hardness test, the system functioned perfectly,” describes Willems. And while
other solutions first had to cool down, the Turck
tags can be read and written directly after leaving
the oven. For the heat-resistant tags, Turck developed a special housing that is easy to assemble and
disassemble. Turck guarantees a service life of ten
years if its products are used in accordance to the
specifications. Currently, a total of 240 tags are in
use at Tower Automotive.
BL ident is an open system that can communicate with all traditional fieldbuses. Turck offers
interfaces for PROFIBUS DP, DeviceNet, Modbus
TCP, Profinet and EtherNet/IP. Each interface has its
own data memory and adapts automatically to the
respective application. Due to its modular design, a
BL ident station with 2, 4, 6 or 8 channels can be
used. The RFID modules can also be additionally
adjusted in terms of software so that each channel
works with a read/write head separately in parallel/multiplex mode. This is particularly important for
applications where two read/write heads are located
very closely to one another, like when a conveyor
chain splits into several chains.
“
We were able to
reduce the read-write
time per station by
almost two seconds
using the FRAM tags,
which enabled us to
speed up the conveyor chain because
stops for reading and
writing are no longer
necessary.
”
Luc Willems,
Tower Automotive
Increase in efficiency
In a heavily automated facility like that of Tower
Automotive in Ghent, the speed of the internal
conveyor chain contributes considerably to an
efficient production process. Important to this is
transparent production, what we call “tracking &
tracing”. Planners at Tower Automotive planned
for this task by installing RFID. The system first
used, however, had an error rate of 0.5 percent
per shift, which was not acceptable, so a new
solution had to be found. “The biggest challenge
in our process are the extremely high temperatures that many RFID systems have trouble with,”
explains Willems. “The parts equipped with tags
are ultimately supposed to go through ovens operating at 180 °C. This begs the question of what
happens to the electronics of the RFID tags under
these extreme temperatures.”

2_2008
“Where many traditional RFID systems only permit
static writing and reading, with the BL ident system,
both reading and writing are possible while the tags
are in motion (on the fly). This issue was important to
us,” says Willems. The FRAM memory (ferro-magnetic RAM) used in the factory make faster data transmission possible and requires very little maintenance.
Depending on the tag and the data volume, the BL
ident system can process read and write cycles at a
speed of 10 m/s. “We were able to reduce the readwrite time per station by almost two seconds using
the FRAM tags, which enabled us to speed up the
conveyor chain – because stops for reading and writing are no longer necessary,” resumes Willems, “this
naturally resulted in higher production.”

tentional inclined position of the nozzle head or even
small drops of paint immediately become quality pro­
blems. The paint stream must be applied precisely
in the middle of the surface of the molding,” explains
große Deters.
It quickly became obvious how demanding this
job was when it came to measuring the most varying
and truly complex molding profiles with the required
resolution of five millimeters. Initial attempts with
laser removal measuring systems failed totally on all
different and non-sufficiently reproducible reflection
properties of the aluminum moldings. Even an ultra­
sound measurement arrangement was proven as
not very suitable for use.
Precise measuring results
The technical break-through was achieved in the end
by using two measuring light curtains from the Turck
product line. “Suddenly, we had precise measuring
results with excellent additional functions. We were
able to do practically everything that we could only
have dreamed of beforehand,” says große Deters.
With two analog and digital outputs each, including
an active or a power supplying 20mA-output, sepa­
rate and unnecessary paint streams can be bloc­
ked as desired, which makes the arrangement very
flex­ible. This means that adapting the system to the
various molding profiles is easy to do.
Another good reason for going with the EZ Array
light curtains, which were developed by Turck’s optics
partner Banner, was the compact design of the device
with an integrated controller. It also had an excellent
cost/benefit ratio. The two-part light curtain makes
start-up easy. All of the evaluation electronics
are integrated into the receiver housing; the electro­
nics can be configured via 6 DIP switches. A threedigit display and an LED bar graph display the status
and orientation of sender and recipient on site.
As an option, parameters can also be set using the
software provided on the receiver. The RS485 inter­
face is used for this purpose and also for transferring
data to the modbus RTU protocol. Because all the
evaluation electronics are integrated in the receiv­
er, an external controller is not necessary. As the
only device of its class, the EZ-Array can be used
in a temperature range of between -40 to +70 °C.
Thanks to an anodized aluminum housing,
the light curtain is also ideal for use in rugged
environments.
“The entire system is compact, small, and has
a nice display, as well as two digital outputs and
can be easily connected to the Siemens S7 con­

enthusiastically. The experts from Venjakob see
huge advantages in the built-in EZ Array control­
ler with regard to maintenance-friendliness and the
possibility of quick responses in case of techni­
cal problems. “If problems occur in the system,
our customers require that we respond within
six hours. We have to eliminate the problem
within twelve hours,” comments große Deters. “Initi­
ally sending a potentially defective controller to the
manufacturer, like with solutions from other sup­
pliers, cannot be afforded.” With Turck light curtains,
the controller can simply be reprogrammed and
subsequently sent to the customer. It‘s as straighfor­
ward as that. However, such a scenario has so far
remained theory because as yet, there have been no
problems with the Turck technology.

EZ-Array: A Clever Light Curtain
The EZ-Array measuring light curtain from
Turck partner Banner is ideally suited for
applications such as hole detection, size/
profile recording, edge and center guidance,
slack control or parts counting. At a resolu­
tion of 5 mm, users have the choice bet­
ween two PNP and NPN switching outputs
as well as 0 to 10V and 4 to 20mA analog
outputs. The EZ-Array can be adjusted to
almost any application above the 5 mm

With this system, a Venjakob paint spray line for
automobile moldings at the aluminum manufactu­
ring facility in Böhmenkirch, Germany, has been
working completely smoothly for 18 months. The
company, which counts all the major automo­
bile manufacturers among its customers, coats
automobile moldings using a patented process that
prevents the chromed surfaces from tarnishing even
when they are exposed to wind and weather over
many years.
Originally built as a test facility, the almost 40
meter long paint line has put test operations behind it
in the meantime. Before the moldings moves through
the line, the system runs at a speed of 25 meters per
minute in order to fastidiously clean the line of dirt
and dust. A cleaning station takes care of this job
right from the start. Powerful nozzles blast ionized
air onto the molding, permanently removing dust
and dirt. Afterwards, in a dust-proof room, two
Turck light curtains, positioned perpendicular to
each other, measure the molding in five-millimeter
grids. The result is an exact virtual, high-resolution
image of the profile. Using the recorded data, the
three spray guns used for the coating are controlled
with great precision in real-time. A subsequent
burn-in process at 180 °C makes to coating wea­
ther-resistant.
What looks comparatively easy at first glance
required a great deal of innovative detail work in the
past several months. That’s why große Deters
proudly refers to a self-developed software
that is used to identify and virtually shield mol­
ding strips that are not to be coated. Today,
thanks to Turck technology, the clever Venjakob
system replaces a paint line in which coatings are
applied at a quality level that could once only be
achieved manually. It is no wonder that representa­
tives from the major automobile manufacturers are
“excitedly” waiting in line in Böhmenkirch.

Energy for the
Olympics:
In the BeijingGuanting wind

by VENSYS

in Saarland,
Germany –
using inductive uprox+
sensors
D
uring the Olympic Summer Games in
August 2008, China appeared as an
environmentally-friendly host. In addition to the use of solar energy and terrestrial heat,
the organizers relied primarily on wind energy,
which alone was intended to cover 20 percent of
the energy demand of all Olympic event facilities.
The electricity is generated in the Beijing-Guanting
Wind Park where 43 wind turbines from Chinese wind
energy market leader Goldwind are in operation. The
wind turbines are provided by VENSYS Energy AG
produced 7,000 km away in the city of Saarland,
Germany.
Worldwide growth
VENSYS wind turbines that were built and
tested in Saarbrücken, Germany, are currently turning in the Canadian Higgins Mountain
Wind Plant, as well as in the German city of Grevenbroich. This year alone, Chinese partner
Goldwind is planning to put three plants into operation with more than 1,000 wind turbines. Other licensees are implementing innovative development ideas
in Brazil, India, the Czech Republic and Spain.
The market opportunities for VENSYS wind turbines are particularly lucrative because the generator
design and construction allows for sufficient wind
production even in low wind regions, believes Board
member Dietmar Knuenz. The exciter field is generated by the permanent magnets made of neodymium-iron-boron (NdFeB) attached directly on the
rotor shaft. Therefore, energy normally used to excite
the rotor can now be sent to the grid. “In the design
of our wind turbines, we rely on constant part reduction by limiting turbine construction to a few high
quality and tested components,” explains Knuenz.
“The VENSYS generator fulfills all the functions of
the classic drive train. We no longer use high-maintenance components that are prone to malfunction,
such as transmissions, intermediate shaft and couplings. By using permanent magnets, we no longer
need excitation coils, slip ring transmission and DC
generation.” The pitch drive with low-wear toothed
belts led to further savings, making lubrication and
sealing redundant.

With an innovative generator design, the Saarland-based VENSYS Energy AG made it all the
way to Beijing. For the Summer Olympic Games,
43 VENSYS wind turbines – built by the Chinese
licensing partner Goldwind – provided environmentally friendly electricity. To achieve this, uprox+
sensors from Turck guaranteed a consistently
optimal rotor position.

friendliness, it makes no compromises in terms of
safety. With regard to safety, the pitch control system
is among the most important components of a wind
turbine. The system measures, monitors and controls
the working angle of the rotor blades on a wind turbine which can change the power consumption. For
example, pitch control allows the rotor blades to turn
into the wind when starting up. During operation, the
output can be held constant despite changing wind
conditions by adjusting the working angle. However,
if a storm gets up, the pitch control rotates the rotor
blades automatically out of the wind in order to prevent damage.
Sensors guarantee reliability
“A malfunction can have fatal consequences,” says
Dr. Stephan Joeckel, Director of Electro-Technology at VENSYS. No wonder that the reliability of the
measurement technology in this field is the highest
priority. That is the reason why VENSYS Energy AG
decided in favor of inductive sensors from Turck. In
each wind turbine, six uprox+ sensors – two on each
blade – simultaneously determine the precise position of the rotors. To do so, each sensor records the
end position of the rotor blades. A seventh sensor
more @
2_2008
determines the position of the maintenance hatch of
the turbine. With the data from all the sensors, the
control system then ensures that each rotor blade
is in the correct position. The power is transmitted
between the motor and the rotor blade via a lubricant-free and maintenance-free toothed belt. In this
process, the power is distributed across several
teeth, thus minimizing wear and increasing safety
and reliability.
In 2007 alone, VENSYS equipped 60 wind turbines with Turck sensors without encountering any
difficulties. “So far, we have only had good experiences,” confirms Dr. Joeckel. “In addition to the
high level of reliability, high quality and an attractive
price-performance ratio, the high resistance to the
high EMC was also an important factor in the decision in favor of the uprox+ sensors. Because of their
direct proximity to the generator of the wind turbines
and the risk of lightening, the topic of EMC plays a
significant role in this application area.”
”
Dr. Stephan Joeckel,
Resistant and impermeable
VENSYS
Because wind power plants are frequently located in
coastal regions with relatively high particulate concentrations, all plant components must meet particularly high requirements when it comes to impermeability. Here, too, the uprox+ series was able to score
some points: In the standard design, the sensors
are encapsulated in a chrome-plated brass housing
with an IP68 degree of protection and meet the high
requirements of the VENSYS developers.
Sensors that are to be used in offshore plants
out on the open sea have to be even more resistant
to aggressive salty and moist air. While those types
of VENSYS wind parks have not yet been developed, the Turck sensors are already best prepared for
such a scenario. Even today, uprox+ sensors with
enormously resistant and especially impermeable
stainless steel housings are being used in the food
industry where they have successfully withstood
aggressive cleansing agents for years.

wenty meters long, almost 5 meters wide
and weighing thousands of tons due to
their size and weight, the centimeterthick steel plates produced and processed in steel
mills do not necessarily rank among the things that
conventional lifting systems are able to move. In
order to be able to safely and comfortably maneuver these steel sheets, powerful solutions from specialist companies are required. Among these specialists is Lubas, a German machine and equipment
manufacturer that has made a name for itself when
it comes to vacuum lifting systems for extremely
heavy loads.
“Our core business involves crossbeams for
weights starting at 5,000 kilograms. But we have
also built a crossbeam for a steel mill that can lift
steel sheets weighing up to 32 tons,” explains Alexia
Bockermann, who is responsible for electro-technical planning and installation at Lubas. “There are
very few companies in Germany that can build lifting
equipment of this magnitude.” According to Bockermann, however, the company is unique in Germany
because of its high vertical range of manufacturing.
What distinguishes Lubas: From steel construction

tion. While the special vulcanized elastomers of the
vacuum suction cups can withstand temperatures of
up to 250 °C, the electronics built into the top side of
the steel structure are considerably more sensitive.
“It isn’t just that the crossbeam is permanently positioned above the broiling hot sheets, but you have to
account for an average temperature of 60 to 70 °C,”
explains Bockermann. “This already places a high
demand on the electronics.”
For this special environment, Turck has provided
the right solution with the BL67 remote I/O station
and pressure sensors from the PS series. “We are
building the decentralized concept with the BL67
stations for the first time. We used to do everything
using terminal boxes in the control cabinet. Rapid
installation using M12 plug-in connectors and electronics modules is a considerable advantage,” says
Bockermann, when explaining the company’s decision to use Turck products. The compact fieldbus
stations are an additional advantage: For the BL67,

Vacuum crossbeams from Lubas lift heavy steel that other lifting systems

53 pressure sensors from the PS series, Turck has developed both a rugged
and easy solution that monitors the vacuum of any suction system.
almost all essential services are provided by this one
company.
Among the most powerful mass-produced lifting
machines from the Lubas product line are the models from the UniTravMega series, which can lift and
transport large-scale sheets up to 18 meters long and
weighing over 25 tons. Lubas is currently constructing
two UniTravMega crossbeams with a lifting capacity of
15 tons each. These crossbeams are equipped with
over 51 large vacuum suction cups arranged in 3 rows
and attached to a massive weight-bearing body. The
vacuum of each individual suction cup is recorded by
Turck pressure sensors from the PS series and shown
directly on site via the display. Lubas has installed two
BL67 I/O stations to record and forward the measured
values to the controller.
Temperatures in the limit range
The sheer weight of the steel sheets to be transported is not the only challenge faced by the vacuum lifting systems from this machine manufacturer. When
it comes to compensating for the oversized sheets,
meaning re-heating in industrial ovens and subsequent specific quenching in cold water, temperatures
of over 200 °C develop directly on the sheets. These
temperatures can damage not only the vacuum
suction cups, the steel structure, but also the hose
connections and the overall electronics of the lifting
systems if they are operated too long without protecmore @

used to connect the lifting systems to the operator‘s
company network. “This gives our customers the
opportunity to monitor via their own company network how many tons the crane has moved or how
many pipes have gone into production.”
Both BL67 stations used in the UniTravMega
record the signals from the 53 pressure sensors
installed above the vacuum suction cups. Their
pivot and swivel displays make it possible to easily
and directly check each individual vacuum suction
cup and conveniently program them using only 3
push buttons, this makes laptops or other external programming devices redundant. “For security and maintenance of the crossbeam, it is very
important to see whether a vacuum is established
on each suction cup. Without the pressure sensors
and the displays, each suction cup would have to
be checked using a test plate. The customer can
spare this expense and effort using pressure sensors,” explains Bockermann.
In addition to its impressive sensor and fieldbus
solutions, Turck’s excellent customer service played
a central role in the cooperation between Lubas and
the Mülheim-based automation specialists. Confirms
Bockermann, “we wanted to avoid suppliers who go
by the motto ‘sell the product and forget the customer’. With Turck, we know that we can get help at
any time in case of problems.”

hether matt black, glossy color or
metallic glitter, perfect coatings on
magazines, brochures or packaging
is not just a matter of individual taste. They attract
attention to the magazine on the shelf and give the
publication a certain air of authority. The greatest challenge in working with such coatings – mostly UV or
dispersion coatings – are the varying processing temperatures with which the coating has to be applied
to the print material. Due to the
large-volume coating containers
used in the industry, the contents
can only be slowly brought up
to the target temperature, which
is a time consuming process. In
addition, the coating cools down
again as it travels the often long
routes between the coating container and the processing. This
means that in the end it can
no longer be processed in the optimal temperature
range.
With the newly developed Bricort mobile coating
temperature control device from Industrie-Automation
Vertriebs-GmbH (IAV), based in Rodgau, Germany,
these problems are now a thing of the past. The starting point for the development o f this product were
repeated attempts by print machine manufacturers to
build a device that offered considerable benefits compared to the relatively imprecise and energy-intensive
method of preparing coatings, explains Guenter Jung,
the technical manager of IAV. “We found that there
existed among print machine manufacturers a certain
pent-up demand with regard to coating temperature
control. This is a gap that we have now been able to
close with our Bricort system.”
Together with the Institut für Druckmaschinen

spent three years developing a compact temperature

Innovation:
The coating temperature is recorded
using the PT100
directly on the anilox
roller (trade show

For this purpose, a PT100 temperature system is
mounted in the connection nozzle to the anilox
roller which continuously reports the output temperature to the controller. This system ensures that
there are no temperature fluctuations because of
supply piping that is too long. “With the help of Bricort, for the first time coating technicians are now
able to maintain narrow temperature tolerances of
only ±0.5 °C and adjust the temperature as well as
the associated viscosity of the coating,” explains
Jann Neumann, a research scientist at IDD and
responsible for the development of the control system.
“Positively surprised”
In a small space in the control cabinet, the Bricort
system consists of an “on-top” multi-lingual, built-in
touch panel for entering the desired processing temperature, as well as a flow path temperature control
device in which the coating is heated up quickly or
cooled down by switching on a cooling device. “This
design has a a cooling efficiency of only one kilowatt,
which is completely sufficient.” This represents an
incredible energy saving compared to conventional
devices with a cooling efficiency of 3 kilowatts and
more,” says Guenter Jung.
Due to its compact and modular design and the
option to integrate additional electronics modules in
the system in any sequence, the Turck BL20 remote
I/O station quickly turned out to be the ideal solution for developers. “We had mainly been looking

remote I/O station combines sensors and actuators with the gateway’s own controller. Thanks to
the TCP modbus protocol, the temperature control
device is also directly connected to the control unit
in the print machine so that the print and coating
process can be controlled using one unit. “Together
with the touch panel, the BL20 station functions as
the heart of the machine,” summarizes Globig.
But the development of Bricort is not the end of
the IAV developers‘ work on fluid automation in coating machines: “We are already thinking about creating an integrated solution that can combine in one
machine all components such as coating preparation, coating supply and the associated piping components and parts,” explains Jung.

dough mixing and dough makeup equipment, along
with cookie and cracker machinery to the baking
industry. Whether the machines are used for bagels,
muffins, granola bars, cakes or a plethora of other food
items, Peerless’ mixing machines, bread dividers and
dough equipment are vital to the baking and snack
food industries. The snack food industry continues to
thrive in many nations across the world. According to
Daryl Thomas, chairman of the Snack Food Association, www.sfa.org, the snack food industry generates
$26 billion dollars in annual sales and is growing at an
average rate of 4.5 percent per year.
Product customization
Local Control
Distributed I/O cuts installation time in half for snack food
equipment manufacturer Peerless Machinery Corporation
A hallmark of Peerless’ continued success is its ability to custom build machines to its customers’ specifications, including mixing bowl capacities and the
way they are installed in the frames (tilt geometry),
the actual frame designs, refrigeration packages and
control systems. Peerless also provides integrated
systems for its customers, such as dough handling
systems that move dough from the mixer to makeup and forming equipment.
Being versatile may be a cornerstone to the success of the company, but customizing machines for
individual customers created some serious challenges for Peerless. This is especially true when designing machines that conform to the size requirements
found in the food manufacturing sector, as well as
customizing control systems.
The first obstacle Peerless faced was standardizing on a network protocol that would synchronize
all systems in order for them to operate in tandem.
EtherNet/IP was the network protocol that Peerless
chose to use because it provides tighter control and
helped Peerless streamline operations. “We see EtherNet/IP as the emerging standard, as it is gaining
worldwide acceptance in the industrial sector,” says
Eric Cruse, Controls Engineer with Peerless. “We also
wanted a system that would allow expansion of diagnostic information and provide an open platform for
our customers.” Although implementing EtherNet/IP
gave the company tighter control, Peerless still had a
centralized cabinet full of drives and PLCs, and was
running lines of conduit with hard-wired cables from
its machines to the controllers. Because of the layout
of the plant floor, the lines of conduit can be up to
250 feet long, and are sometimes routed to a different floor in the plant altogether.
Another challenge for the company is maintaining a clean manufacturing environment without harming the components that keep the plant
up and running. Since all of Peerless’ applications
are used in the food industry, it is imperative that
the machines remain sanitary. High pressure, high
temperature washdowns, often using harsh cleaning agents, are necessary to maintain a sterile working environment.

To address these issues, Peerless chose to implement distributed I/O to remove the main control

The company accomplished this by creating substations on each machine using Turck USA’s BL20 EtherNet/IP terminal-wired I/O. BL 20 is an IP 20-rated

the distributed I/O structure, and runs all localized
sensors and other equipment through these boxes.
Each substation contains one BL20 system that
maintains control for one machine, and utilizes Turck
fully connectorized cordsets to transfer information
from the substation to the main control cabinet. By
doing this, Peerless no longer needs to run long lines
of conduit and hard-wire each machine to the main
control cabinet. “Converting to distributed I/O has
cut in-plant installation time in half,” adds Cruse.
Local support and product flexibility
According to Cruse, implementing a standard I/O
structure was the primary reason Peerless chose
to use Turck’s distributed I/O products, because it
negates the need for constant firmware updates.
“We chose Turck because of the local support and
delivery they provide, as well as the availability of

wiring, the signals from the field devices are
collected at the remote I/O station in the plant,
transmitted to a digital protocol and sent via bus
cable to the control system. So, instead of needing many analog or digital input and output cards,
the PLC or process control system only needs
one bus card.

Franz Meiser, Erdgas Südbayern, has an eye on everything: “All
measuring results are displayed in the display of the 19-inch cards.”
Temperatures, pressures and other measurement signals are
recorded and transferred to the control room via remote service
Despite all the bus technologies available today,
there are still situations in which the use of traditional
point-to-point interface technology is still justified. In
this method, each signal from each field device is
transmitted directly to the control system. The signals are first galvanically separated, then prepared or
formed before they arrive from the field to the PLC
or the process control system. The purpose of this
parting plane is to protect the control system from
disruptive signals or undesired transmissions from
the field, and to support the explosion protection
method. Because each signal reaches the control
system separately, it must have the appropriate
number of signal inputs and outputs.
Use in gas supply
If only a few field devices in remote satellite stations need to be connected to the control technology, interface solutions are the best option because
remote I/O and fieldbus systems would become
cost prohibitive. Gas supply is often such a scenario. “We have to constantly keep an eye on the
more @

current measurement values of our approximately
160 supply locations. In this case, a powerful but
not too expensive interface technology is a decisive
factor for efficient plant operation. Fieldbus technology would not be a financially feasible option
here,” says Karl-Heinz Markut, responsible for network control system at erdgas schwaben GmbH.
The company supplies natural gas to 165 cities and
communities in all of Swabia and parts of Upper
Bavaria, Germany, as well as seven natural gas
redistribution companies; a total of 5,000 pipelines
are connected. Erdgas Südbayern, a nearby gas
supply company, supplies natural gas to 247 cities
in Upper and Lower Bavaria, as well as 24 municipal redistributors. This provides southern Bavaria
with a modern natural gas pipeline network with
approximately 800 transfer stations.
Pre-suppliers, such as Bayerngas, transfer the
natural gas to the transfer stations within the network
of regional suppliers. Both the pre-supplier, as well
as the regional supplier, have installed their measurement technology, including meters, in the transfer
gas stations. The measurement values are retrieved

Service-oriented: The Turck subsidiary Mechatec provides, according to customer specifications, configured,
ready-for-connection control cabinets to erdgas schwaben, completely wired with telecontrol technology
along with all documents
via telecontrol technology and displayed centrally in
the control room.
In the transfer stations, the pressure of the incoming gas – about 60 bar in the winter and about 40 bar
in the summer – is reduced to a standard pressure of
0.2-1 bar in homes and 10 bar in commercial properties. Because when forming under pressure, temperatures up to minus 20 °C can occur, the stations have
heating systems that heat the pipelines up to a temperature of 10-15 °C.

In order to guarantee smooth operation, certain measured values must be recorded in each station, transferred to the control room and monitored. Among other things, the inlet and the outlet pressure is recorded, the temperature of the gas determined and the
impulses from the flow rate sensors for determining
the gas volume counted. Additional signals develop
when measuring the filling level for the container, the
valve position displays and with the dewpoint sensors
that permit down-to-the-degree pipe heating. All sensors are installed in zone 1.
According to the motto “Trust is good, checking is better,” Franz Meiser, responsible for
the electrical telecommunications technology
at Erdgas Südbayern routinely has the measurement values displayed in the control room
compared to the results on the measuring points. “For
this purpose, we use the Turck interface technology
with displays,” says Meiser. “We used to have to read
each manometer, each thermometer and each and
every measurement directly at the measuring point.
Today, all results are displayed on the 19-inch cards
displays. So there is no need to have the specialist
on site, any employee can give the measurement
values to the control room by telephone.”
Ready-to-connect control cabinets
At erdgas schwaben, Karl-Heinz Markut does not rely
on 19-inch cards, but on DIN rail devices. He had this
choice because Turck offers most interface solutions
both as DIN rail devices, as well as the 19-inch format.
In addition to the quality of Turck interface solutions,
its extensive product portfolio impressed the Swabian gas supply company. “We have purchased completely configured control cabinets from Turck that our
employees only have to connect to in the stations,”
explains Markut. “Besides the interface technology,
the control cabinets also contain telecontrol technology constructed in accordance to our specifications,
everything is completely wired and equipped with a
circuit diagram, as well as all necessary documents.
For us, this represents true added value.”
The control cabinets are built by Turck subsidiary Mechatec. Mechatec offers complete customer­
specific, electro-mechanical solutions ranging from
customized cables to completely pre-installed control cabinets for all areas of industrial automation
technology. Therefore, Mechatec perfectly complements the solution packages from Turck, the sensor,
fieldbus, connection technology and interface specialist, when there is a need for additional customeroriented products.

Global portfolio
Turck offers its customers a multitude of interface components
for separating, forming, processing, converting and adapting
analog signals. The devices are available for DIN rails, as well as
European cards for 19-inch racks and an IP67 model in the form
of IMC cartridges.
Mr Kromhout, aren’t you afraid that
interface technology will die out in
the future with regard to modern
fieldbus technologies?
On the contrary! Many plants in southeast
Asia, China, India or Russia will be even
more and more intensively equipped with
interface technology. For the operator,
the advantage is that they do not have
to have fieldbus specialists. In interface
technology, a multimeter is needed to
make a diagnosis, for modern devices
you may just look at the device.
In your opinion, what are the
special challenges in interface
technology?
To offer a product portfolio that can be
used globally and that meets all requirements in interface technology will remain
the biggest challenge for manufacturers,
in my opinion. In growth markets such
as the BRIC countries (Brazil, Russia,
India, China), the basic functionality of
the interface technology must be offered
at a shame­lessly inexpensive price per
channel. Furthermore, the “footprint”,
meaning the space required for it in the
control cabinet, is becoming increasingly
important.
Beyond the basic functions, sustainable interface technology has to offer a
noticeable benefit for the customer, for
example, simplified planning through universal voltage supply or simplified error
detection through an intuitive menu navigation via the display. Turck has invested a
lot in this added value. And those who want
even more comfort can use the functionality
of our DTMs.
You heavily promote the issue of
asset management in the phys­ical
layer, meaning the connection
between field device and process

control system. How does the market react to this option?
With our slogan “Asset Management
Enabled”, we express the fact that we
also consider the physical layer to be an
asset or an article of value. Via all three
areas of the physical layer – point-topoint, point-to-bus, bus-to-bus, Turck
offers the option of subjecting these to an
additional diagnosis and integrating them
into asset management systems. That is
how our interface technology monitors
both the connection to the field instrument, as well as to the process control
system. Using FDT/DTM, the devices
allow for a far-reaching diagnosis – and
also for the traditional 19-inch technology.
What direction will the interface
market pursue in the future?
The market for interface technology will
remain stable, but will be characterized
by a geographical shift. As long as the
technical level of a service technician in
the growth markets does not meet the
requirements of fieldbus technology, we
will experience reasonable growth. In
my opinion, a considerable number of all
applications in process automation will
also be implemented in traditional pointto-point connection in the future because
the benefits of a fieldbus do not justify the
additional costs in all applications.
But regardless of how the customer
acts today or in the future, Turck offers
innovative products for all connection
paths in the physical layer – from interface technology to remote I/O to fieldbus
solutions. And should a customer not be
able to meet a special requirement with
our standard products, thanks to our
development and production location in
Germany, we are able to develop customized solutions at any time.
As the Director Product Management Process Automation, Ryan
Kromhout is also responsible for
the comprehensive portfolio
of interface solutions at Turck.
Despite fieldbus and remote I/O
technologies, he also sees a
large market for the company’s
interface product line in the
near future.

20 years. The Delémont-based company knows

the necessary tools that extrusion coating requires.
High flexibility
The extrusion coating technology that Interprox in
Switzerland has perfected offers the highest flexibility with regard to configuration, requirement profiles
and installed electronics. There are almost no limits with respect to housing forms. Almost anything
that seems reasonable to a design engineer can be
implemented. This means that, upon request, housing forms can be changed later on if turns out that a
modification further improves the sensors’ features.
The extrusion coating technology even makes it
possible to integrate mechanical assembly solutions,
such as screw holes, thread inserts or – with the use
of transparent plastic – easily visible LEDs, directly
in the housing. This eliminates additional assembly
work and maintenance costs. If the customer wanted a potato-shaped sensor, then Interprox would be
able to meet this request.
Extrusion-coated sensors not only offer the
above-mentioned benefits in terms of construction
and installation, they are also enormously resistant
to environmental factors such as temperature, moisture, vibration or even aggressive acids or oils. In the
end, the electronics are as securely embedded in the
plastic as the gold reserves are in Fort Knox.
Balancing the three: Mechanics,
electronics, plastics
When so many advantages speak in favor of extrusion-coated sensors, you might ask yourself why
all sensors aren't manufactured using this technology. The answer lies in the complex relationship
between mechanics, electronics and plastics. For
example, the heated, fluid plastic may not exceed
a certain temperature while it is being sprayed onto
the electronics. Even the maximum pressure in the
tool must be aligned with the electronic components used. And finally, the extrusion coating technology works only up to certain wall thickness and
size because otherwise the plastic would no longer
harden evenly.
When it comes to producing extrusion-coated
sensors, the challenge is to find the right balance
between mechanics, electronics and plastics, and to
optimize everything for the respective sensor application. Even the selection of the right plastic can be the
deciding factor between the success and failure of a
sensor design. For example, sensor's extrusion coated
using the Duroplast method with a low pressure and
high temperature are particularly well protected against
mechanical and chemical influences. On the other
hand, this plastic tends to be brittle, requires complex
injection tools and a long production process.
Even though Thermelt plastics take a while
to process, they can be placed on the electronics
board at a low temperature and low pressure. The
material has a high chemical resistance, but cannot

withstand mechanical loads for a long time. That is
why it is primarily used to isolate electrical contacts,
for example, in automobile construction.
More than sensors
The sophisticated technology of the Swiss
Interprox is not only ideal for extrusion coating sensors, but can be used in any situation
where compact electronic components have
to be packaged as ruggedly as possible to be
resistant to environmental factors. Especially
when special demands are made on the housing, extrusion coating technology opens the
door to previously impossible solutions. For
example, the Swiss company is able to manufacture sterile products for use in medical technology – it is embedded in an extrusion-coated
plastic housing – that can withstand more than
500 sterilization cycles without damage. Such
customized solutions are developed by the
Turck subsidiary duotec, which is represented
at production facilities in Delémont, Beierfeld
and Halver. For more information, please visit:

Thermoplasts ultimately have to be processed at a
high pressure and a high temperature. Using thermoplasts, extrusion-coated sensors provide mechanical
stability and may also be used in food and beverage
related production industries.
No problem:
Various expansion
phases of a sensor
Customized designs
The Swiss extrusion-coating experts have launched
sensors on the market that are ideally suited to
the installation environment – for example, direct
assembly in the grooves of pneumatic cylinders
– and that considerably reduce assembly time and
expense due to integrated mechanical mounting
equipment. In addition to the standard products
Turck customers can also use the technology and
production know-how to design and develop individual customized solutions.
Starting with a quantity of about 3,000 to 5,000
samples per year, Interprox produces individually
developed sensors that a customer can optimally
plan into the design of its product or machine. This
allows sensors to be mounted in areas that are
impossible to reach with conventional housing technology. For various expansion phases, there is also
the option of installing various housing forms with the
same electronics.

How Temperature
Sensors Work
Part 4 of our basic series on the design, functional principles and application
options of the most important sensor technologies
T
here are numerous different options for
detecting temperatures, ranging from
simple diodes to highly accurate thermal
noise thermometers. Primary thermometers that
detect the temperature without previously calibrating other thermometers are frequently used in labs.
However, in the industrial area, users mainly rely on
secondary thermometers for measuring temperatures that require calibration. In practice, resistance
thermometers or thermo elements are used in industrial applications. Due to the requirements for accuracy and the processing of measurement signals, the
following devices have become standard:
Resistance thermometers record the temperature
using the temperature dependency of the electrical
resistance. Pure metals show the strongest resistance
changes, especially very pure precious metals. You can

distinguish between positive temperature coefficient
(PTC) thermistors, whose resistance increases with a
rising temperature, and negative temperature coefficient
(NTC) thermistors which have the opposite behavior. If
the resistance shows an approximate linear behavior,
the temperature value can simply be recorded using a
polynomial equation. As a rule, resistance thermometers
have a measurement range of -250 to about 800 °C.
Products from this category include standardized sensors made of platinum (e.g. Pt100 with 100 W at 0 °C).
They are used for temperature measurements for various applications in which a high level of accuracy is
required.
accurate measurement of the reference junction
temperature.
Thermo elements may not be as precise, but
they react faster than resistance thermometers.
Thermo elements consist of two different metals or
semiconductors connected to one another. If there
is a temperature difference between both metals,
an electrical voltage develops at the junctions. This
phenomenon is also called the Seebeck effect. The
thermo-electric voltage (also called thermo-electric
power) is temperature dependent and, in metals, has
the size of several microvolts per Kelvin.
In actuality, a temperature difference between
the hot junction and the cold junction is recorded. If
the temperature on the hot junction has to be determined, the temperature at the cold junction has to be
known, and vice versa. In practice, the cold junction
temperature is recorded using a separate temperature sensor. The thermoelectric voltage series permits inference of the temperature at the hot junction
(measuring point). The thermo elements are mostly
used to determine high temperatures up to 1,000 °C.
The precision depends, among other things, on the

Infrared sensors are suitable for recording the surface temperatures ranging from about -70 to 1,000 °C.
The sensors convert the thermal radiation being sent
from one object in a wavelength range of 0.7 to 20 µm
into an electrical signal that is processed into a signal
that can be evaluated. What is important here is the
D:S ratio (distance : spot) that the measuring field
diameter indicates at a given distance. Complete
coverage of this field by the object’s surface whose
temperature is to be monitored is optimal.
Among the greatest challenges in temperature measurement is the fact that the optimal measuring
points are often difficult for the operator on site to
access. That is why there is a demand for application-specific sensor solutions that can be tailored
with highly flexible process connections and whose
displays are easy to read in any location. Taking
these requirements into consideration, Turck has
added intelligent solutions for temperature measurement to its product portfolio in the last few
years.
In addition to the infrared sensors, which have
a measuring range of 0 to 300°C with wavelengths
from 8 to 14 μm, and are produced by Turck’s partner
Banner Engineering, Turck’s Pt100 resistance thermometer is IP 67 rated. The housing is made entirely
of stainless steel and is highly EM compatible. The
electrical connections are metal-armored and offer
high mechanical stability and operating safety.
When it comes to temperature sensors, the user
has the choice between different sensor lengths and
diameters. Furthermore, using protective tubing, the
temperature sensor can also be easily adapted to
very critical locations. In cooperation with numerous
connection options - direct or using an M12 standard cable – and variable output signals, the Turck
product portfolio guarantees maximum flexibility in
temperature measurement.
