technology delivers process-specific information which
enables high-quality production. For this, the safety and
hygienic requirements in the design of the measuring
instruments and the connection of the sensors to the
production plant must be fulfilled optimally with respect to
ease of cleaning.
3
Hygienic design
The hygienic design of plant components in contact with products is an essential
prerequisite for avoiding microbiological contamination, and with that, ensuring product
quality. As part of the overall hygienic concept of a plant, the measuring instruments
used must comply with special requirements on material, surface quality, process safety,
connection engineering and cleanability in the scope of the CIP process.
As a company member of the European Hygienic Engineering and Design Group (EHEDG),
WIKA contributes to the international standards and combines hygienic design with
high-quality measurement technology.
Materials
Austenitic stainless steel is used as a standard material for wetted areas. In the food and
beverage industry and also in the pharmaceutical industry, 1.4404 and 1.4435 grades are
preferred.
Stainless steels are inert to the majority of foods and pharmaceuticals, while also offering
good corrosion resistance to disinfectants and cleaning agents. In this respect, 1.4435
displays a better corrosion resistance than 1.4404. For specific applications, special alloys are
used, such as the fully austenitic stainless steel, 1.4539 (904L), or Hastelloy C and Inconel,
and also plastic coatings such as PFA (perfluoroalkoxy) or PTFE (poly-tetra-fluoro-ethylene).
With diaphragm element measuring instruments, we use the highly corrosion-resistant nickel
chrome alloy, 2.4668 (N07718), in order to achieve an optimal measurement performance
with higher robustness.
As a standard material for all those metallic surfaces that will come into contact with the
process medium, we use stainless steel 1.4435.
Surfaces
An important aspect in the cleaning of a plant using CIP/SIP processes is the quality of the
surfaces in contact with the process medium.
To enable the easy cleaning of the measuring instruments, and also to prevent biofilms, the
wetted surfaces must be passive and free from microscopic flaws. In addition to the surface
topography, the surface roughness is an important criterion for cleanability. In the standards,
such as EHEDG Doc. No. 8, “Hygienic equipment design criteria”, a roughness of Ra < 0.8 μm
is considered as sufficient for normal cleaning processes.
For sensitive biotechnology processes, surfaces with a lower roughness are needed, e.g.
Ra < 0.38 µm per ASME BPE.
4
Hygienic design
Electropolishing
By using electrolytic polishing, the cleanability of the surfaces can be improved. In this
way, essentially, the topographical structure of the surfaces is smoothed and therefore the
roughness is decreased. A further advantage is that electropolishing increases the passive
layer of stainless steel, and thus the corrosion resistance is improved, especially with
reducing media.
5
Sealing materials
In the selection of suitable sealing material, various process
parameters and also the process media are important.
Sealing materials must be toxicologically harmless and
sufficiently resistant to abrasion, be resistant against
aggressive cleaning and disinfecting media, and be stable in
superheated steam at high sterilisation temperatures.
Predominantly, special compounds are used for O-rings
or form seals, for example fluororubber-based (FKM) such
as VITON®, ethylene-propylene-diene material (EPDM) or
poly-tetra-fluoro-ethylene (PTFE). The materials used for the
sealing elements, and also their manufacturing processes,
must conform to the rules of the regulatory authorities and
organisations.
6
Hygienic design
Process connections
Process connections which are used in CIP-capable equipment should not constitute any risk in respect to cleaning.
They are characterised by the following features:
■■ A defined compression of the sealing element through a
metallic stop
■■ Centring via a cylindrical guide
■■ Crevice-free sealing on the inside of the pipe
For this, there are connections such as those in accordance
with DIN 11864, NEUMO BioConnect®, BioControl® and
VARIVENT®.
The widely used connections in accordance with DIN 11851
(milk thread fitting) and DIN 32676 (clamp) were originally
developed to disassemble plant components easily. They
are therefore ideally suited to equipment that needs to be
removed for cleaning. If measuring instruments with these
process connections are operated with CIP cleaning, the
appropriate profile sealing has to be used.
Process connections with metallic sealing components
(thread with sealing cone) form a gap at the sealing point and
are therefore viewed very poorly with respect to cleanability;
especially with recurrent sealing and fitting following the
calibration of the measuring instruments.

Case
The design of the non-wetted parts must be made so that the equipment is easy to
clean from the outside as well. Particularly with open processes in food production,
the machinery and equipment must be cleaned after production. For this, WIKA has
developed specific hygienically designed cases. These are easy to clean from the
outside. Without any gaps or corners and with a high IP protection, these are especially
suited to the harsh conditions of washdowns.

Connection to the process with
diaphragm seals
The connection of pressure measuring instruments to the process is ideally performed by means of diaphragm seals with
hygienic connections.

Advantages of diaphragm seals
Diaphragm seals separate the pressure measuring

- additional sealing elements are eliminated, and so the
instrument, pressure sensor or pressure switch from the
free of dead spaces or where dead spaces are reduced to
a minimum. The isolation is achieved by means of a flexible
metal diaphragm. The internal space between the diaphragm
and the pressure measuring instrument is completely filled
with a system fill fluid. The process pressure is transmitted
by the elastic diaphragm into the fluid and from there to the
measuring instrument.

as a result of the measuring cell's metallic construction
maintenance burden is significantly reduced. Ceramic
measuring cells exhibit a high sensitivity to dynamic loads.
With any sudden pressure spikes, the ceramic cell can
be destroyed. In these cases, combinations of measuring
instruments and diaphragm seals are clearly preferable.
Diaphragm seals
Possibilities for combination and assembly
The combination of mechanical or electronic pressure measuring instruments with flush diaphragm seals meets the stringent
demands made on hygienic instrumentation and is suitable for even the most difficult measuring requirements. Assembly of
the diaphragm seal to the measuring instrument may be made via a direct connection, for high temperatures via a cooling
element or via a flexible capillary.

Diaphragm seals
Diaphragm seals are mounted to existing fittings. Usually the fittings consist of T-pieces
which are integrated into a pipeline, or of welding sockets which are welded to a pipeline,
the process reactor or a tank.
Diaphragm seals offer the advantage that the “contact surface” between pressure
medium and diaphragm is relatively large, thus ensuring accurate pressure measurement.
Furthermore, they can be easily removed for cleaning or calibration.

Proven over decades, diaphragm elements can also
withstand pressure spikes and overloads thanks to their
strong diaphragms. Through this, the danger of damage to
the flush diaphragm is clearly reduced.
Autoclavability
The instruments can be completely autoclaved. This means
that they can be steam-sterilized together with the sterile
container in an autoclave.
Thus, the measuring instruments can be installed just before
the sterilization in order to save time and effort in preparation.

Electrical temperature measurement
Resistance thermometers are equipped with metallic-conductor based sensor elements which change their
electrical resistance as a function of temperature. The connection to the evaluation electronics (transmitter,
controller, display, chart recorder, etc.) can be made with a 2-, 3- or 4-wire circuit, depending on the application.
In the food and beverage industry, as well as in pharmaceuticals, biotechnology and cosmetics manufacturing, the
focus is on more than just providing temperature readings.
The instruments for electrical temperature measurement are characterised by the following features:

Temperature transmitters
Transmitters convert the temperature-dependent change in resistance of
resistance thermometers or the temperature-dependent voltage change in a
thermocouple into a proportional standard signal. The most commonly used
standard signal is the analogue 4 ... 20 mA signal, though digital signals (fieldbus)
are gaining more and more importance.
By using intelligent circuit concepts with analogue 4 … 20 mA signals, any sensor
errors that occur are signalled and simultaneously transmitted with the measured
value over a two-wire line (current loop). The conversion and transmission of the
standard signals (analogue or digital) is made over long distances and completely
fail-safe. A temperature transmitter can either be mounted directly at the measuring
point in the connection head or on a DIN rail in a control cabinet.

Mechanical temperature measuring
instruments
For temperature measurement with mechanical temperature measuring instruments, WIKA
manufactures bimetal and gas-actuated thermometers.
Due to their simple design, bimetal thermometers are suitable for displaying temperature
reliably, even under difficult conditions such as shocks or vibrations.
If, however, fast temperature measurement is required or if long distances have to be bridged
without power supply, gas-actuated thermometers are recommended.
Based on these measurement methods, there is a comprehensive range of instruments.
For hygienic applications in areas such as the food, beverage, pharmaceutical, cosmetics
manufacturing and biotechnology industries, some examples of mechanical temperature
measuring instruments with stainless steel cases are listed below.
For all thermometers, WIKA offers a comprehensive range of themowells with hygienic
process connections.

Continuous level and limit detection
The float-based level measurement is not influenced
by moving surfaces, electrical conductivity, dielectric
constants, foaming and boiling surfaces.
When selecting the correct measuring principle for sanitary
applications, e.g. use in fermenters, various criteria need
to be considered with which float-based measurement
technology brings advantages. Generally, in the process of
fermentation, agitators and their movement cause foaming
on the surface of the medium, where the foam can be finepored or coarse-pored, depending on the process.
Reed chain
For continuous level and interface measurement, depending
on the application and measuring length, different sensor
systems are available. The quasi-continuous system is based

on a resistance measuring chain with reed contacts as 3-wire

With resolutions from 5 to 20 mm − depending on the

Magnetostrictive level
measurement
These level sensors are used as measured value pick-ups for
the continuous recording of liquid levels, and are based on
determining the position of a magnetic float according to the
magnetostrictive principle.
The measuring process is triggered by a current impulse.
This current produces a circular magnetic field along a wire
made of magnetostrictive material which is held under
tension inside the probe tube. At the point being measured
(liquid level) there is a float with permanent magnets acting
as a position transducer. The superposition of these two
magnetic fields triggers a mechanical wave in the wire.
This is converted into an electrical signal at the end of the
wire in the sensor housing by a piezoceramic pick-up. The
measured propagation delay enables the origination point
of the mechanical wave, and thus the float position, to be
determined with high accuracy.

Installation examples
Process connection of the
BioControl® system
The pharmaceutical BioControl® system is used to connect
pressure and temperature measuring instruments to piping
systems and vessels. For the different types of problems
encountered in sanitary applications, there are various
designs of the BioControl® system with component approvals
available.
An advantage to the user is that the system is highly flexible.
In the design of the plant, it makes no difference whether
the port is fitted with a pressure or a temperature measuring
instrument. Design errors can be avoided due to the
modular system with standardised interfaces. Furthermore,
storage costs are reduced to a minimum since only a few
components need to be kept in stock.
Process connection of the
VARINLINE® system
To connect the pressure and temperature measuring
instruments to the aseptic processes, aseptic fittings are
required. For this, VARIVENT® connections are available
to the process engineer in the production of food, which
ensure a dead-space free transition from the process line to
the measuring instrument. WIKA pressure and temperature
measuring instruments with VARIVENT® connections fit
smoothly into the VARINLINE® access units.

Installation examples
Clamp model 990.22
with sterile extension
WIKA has developed a diaphragm seal system with a
process connection that is specifically suited to pressure
measurement in sanitary applications. The EHEDG
(European Hygienic Engineering & Design Group) has
tested the model 990.22 clamp with sterile extension and
has certified it as having exceptional suitability for sanitary
applications.
The model 990.22 clamp with sterile extension is easy
to handle when installing and removing. With the help of
a special welding socket, a flush sealing to vessels and
pipelines is ensured. Thus it offers the user an easy-to-clean
pressure measuring point, which is suitable for CIP and SIP.
Weld-on adapter for flush pressure
transmitters
In open vessels or vented tanks, the operator measures the
level hydrostatically with a pressure transmitter. For this, one
installs the measuring instrument in the bottom or close to
the bottom. This measurement can be used on practically all
liquids whose density remains constant. The measurement
is not affected by pastes, emulsions or blends of solid
ingredients. Also, hydrostatic level measurement is not
affected by foaming on the liquid surface.
To mount the measuring instrument, a socket is welded
into the vessel wall and the inside smoothed. This enables
a flush and easy-to-clean measuring point for pressure
measurement in a vessel.

Process adapter system
The WIKA process adapter system has been developed to meet the requirements of

connections (e.g. clamp, threaded, VARIVENT® or NEUMO®).
All parts are made of 316L/1.4435 stainless steel. The O-ring for sealing the process
(optional) is supplied with a 3.1 material certificate per EN 10204. It is available in either
EPDM or FKM and is listed as FDA, USP class VI, as well as 3-A 18-03.
The WIKA adapter system meets the high requirements of sterile processes and has been
developed in accordance with the 3-A Sanitary Standards.

Thermowell for orbital welding
Flow-through housing
The model TW61 thermowell serves as the process
connection for a model TR21-B or TR22-B resistance
thermometer. The thermowell is especially suitable for the
adaption of temperature measurement into pipelines for
sanitary applications and for CIP and SIP processes. The
ease of cleaning is ensured through the optimal hygienic
design. To integrate it into the process, the thermowell is
directly orbitally welded into a pipeline. The connection ends
are smooth and prepared for orbital welding.
The measuring insert can be withdrawn together with the
connection head. This makes it possible to calibrate the
thermometer with the entire measuring chain, on-site, without
disconnecting the electrical connections. In addition, this
avoids having to open the process, and thus the risk of
contamination is minimised.
Angular housing
For small nominal pipe sizes and in cramped conditions,
angular housing thermowells are available.
The thermowell is dead-space optimised and is welded
automatically, thus it is preferable to thermowells with welding
balls and hand-welded seams. The measuring instruments
should be aligned horizontally in order to avoid air pockets in
the cupola.

Portable pressure generation
Measuring components
Hand-helds, calibrators
Test pumps serve as pressure generators
for the testing of mechanical and electronic pressure measuring instruments
through comparative measurements.
These pressure tests can take place in the
laboratory or workshop, or on site at the
measuring point.
High-accuracy pressure sensors and very
stable standard thermometers are ideal
for applications as references in industrial
laboratories. Due to their analogue or digital
interfaces, they can be connected to
existing evaluation instruments.
Our hand-held measuring instruments
(process tools) offer a simple capability
for measurement or simulation of all
established measurands on site. They
can be operated with a wide variety of
pressure sensors or thermometers.

Fully automated calibration
systems as complete solutions
High-accuracy digital precision measuring
instruments are ideal for applications
as reference standards in industrial
laboratories or metrology, enabling
high-accuracy calibration. They feature
exceptionally simple handling and an
extensive range of functionality.
Due to their integrated controller,
these instruments offer exceptional
convenience. Typically, a fully automated
setting of the required value can be set via
the interface.
Fully automated calibration systems
are customer-specific, turnkey
installations which can be fitted in
laboratories as well as in the production
environment. With integrated reference
instruments and calibration software,
calibration certificates can be generated
and archived in a simple and
reproducible way.
