Symaro temperature –
reliable and precise
measurement at any place
Flexible sensors for temperature
measurement
Symaro offers temperature sensors with
all important active and passive output
signals. The active sensors can be quickly
adapted to the situation at hand using a
number of different, easily adjustable
measurement ranges.
Exact measuring results in
every application
– The best possible comfort even during
dynamic processes is ensured by the
optimum weighting of room and wall
temperatures.
– In addition to outside temperature, to
keep heat requirements economical,
the outside sensors measure wind, wall
temperature and solar radiation.
– Strap-on, immersion and cable sensors
optimize control thanks to their sophisticated design and short reaction times.
4
– The air duct sensors deliver precise
results with their mean value measurement, regardless of temperature stratification or flow conditions. The duct
sensors can therefore be flexibly
positioned.
Innovative and simple installation
All temperature sensors can be quickly,
securely and easily mounted – saving
time and money during installation.
– The mounting plate allows the room
sensors to be wired in advance. Then,
after all plastering and painting work
is finished, the sensor is snapped on.
– When it comes to preinstalled protection pipes, immersion sensors are
simply snapped in place.
– Strap-on sensors can be fixed fast and
securely, regardless of the pipe diameter, using the supplied clamping strip.

Symaro air quality –
energy efficiency and
more comfort
Unique product range with stable
measurement method
The air quality sensors cover all requirements and are suitable for every type of
building. The high-precision multisensors
(CO₂/VOC 1), CO₂/T and CO₂/T/r.h.) are available for room and duct applications, and
also with an attractive display.
Efficient in usage
Through infrared absorption measurement
(NDIR), air quality sensors determine the
CO₂ concentration. And because of an additionally integrated reference light source,
they can also periodically recalibrate themselves. This ensures freedom from maintenance, long-term stability and maximum
measuring accuracy. The sensors also
deliver immediately, precisely measured
values regardless of room occupation.
Ultimately, you save substantial start-up,
service and operating costs.
8
Comfortable and economical
installation in the air duct
Fast, secure and cost-efficient installation –
with no need for additional duct installation housing or sealing measures: The
installation of air duct sensors is very easy
thanks to their ergonomic, installationfriendly housing. Due to the infinitely
variable immersion depth, the sensors can
be optimally adapted to every installation
situation. Additionally, because of the
patented measurement system, alignment with the flow direction is no longer
needed. Two totally separate chambers for
measurement modules and connection
terminals prevent air outside the duct from
affecting the measurement accuracy.
Energy-saving room comfort
Optimum air quality with low energy
consumption: Combined with systems
from Siemens, controllers and variable
speed drives, Symaro air quality sensors
allow for optimized demand-controlled
ventilation 2). Thus, 20 to 70 percent in
energy and cost savings can be achieved.

Symaro pressure –
highly precise and robust
pressure measurement
Symaro pressure sensors are
designed to quickly and accurately
measure the pressure in all
fields of use.
10
Precise pressure sensors for
all requirements
Symaro covers the entire range of
requirements for pressure measurement.
It comprises sensors for measuring very
low to high pressures in all kinds of
different media such as liquids, gases,
water, refrigerants and air. Measurement
cells matched precisely to the pressure
range increase the measurement accuracy. This eliminates the need for temperature or pressure calibration.
Innovations for very good
long-term stability
Thanks to patented membranes, the
operating points of the Symaro pressure
differential switch for air are stable over
a long period. And because of its goldcoated contacts, even frequent operating
cycles pose no problem.
The individually laser-adjusted pressure
difference sensors for air and non-aggressive gases use the patented ceramic
bending bar technology. That allows a
highly accurate pressure measurement,
which is stable over a long period, even
with highly dynamic processes.
Ideal measurement even during
intensive load change
The robust pressure sensors for liquids
and gases are based on a stainless steel,
piezo-resistive measuring system. They
are ideally suited for the measurement
of static and dynamic overpressures with
intensive load change. Their fully encapsulated electronics design permanently
protects them against the effects of temperature and humidity.
Precise within use – even in
refrigeration areas
When it comes to Symaro pressure sensors for use in refrigeration areas, the
stainless steel membrane is welded to
the housing with no need for a seal. This
means they can be used in conjunction
with all refrigerants, even ammonia and
carbon dioxide, as well as at high process
temperatures and with aggressive media.

Symaro flow – flexible
and efficient measurement
of flow
Innovative sensors for all requirements
Be it the flow of liquids or the flow of
air, Symaro offers everything needed to
ensure accurate flow measurements –
from flow sensors to flow switches and
velocity sensors. Since all types of flow
sensors are available with DC 0...10 V
or 4...20 mA outputs, the products are
very versatile.
Ruggedness, stability and longevity
The vortex flow sensors for liquid media
are available in glass fiber reinforced
plastic or rugged red brass. The sensors
contain no moving parts, which makes
them dirt-resistant and ensures an excellent media resistance. As a result, they
ensure longevity and excellent long-term
stability.
14
The flow switches are made of glassfiber reinforced plastic featuring a Reed
contact, which is actuated by a magnetic
field, absolutely contact-free and without
a return spring. This leads to stable switching points. Depending on the model, the
switches offer pressure ranges up to 25
bar without using bellows, resulting in
pressure-independent switching points.
This means that the switching point is
solely dependent on the volumetric flow.
The Symaro range of flow switches covers
nominal sizes from DN 10 to DN 200.
The air velocity sensor offers three measuring ranges: 0...5, 0...10 and 0...15 m/s.
Thanks to its special thin-film sensing
element, the sensor operates independently of the direction of flow and is
dirt-resistant.
