User Manual
Unique product range with stable
measurement method
The air quality sensors cover all
re
quirements and are suitable for every
type
of building. The high-precision
multi-se
nsors (CO
₂
/VOC
1)
, CO
₂
/T and
CO
₂
/T/r.h.) are
available for room and
duct applications, and also with an
attractive display.
Efficient in usage
Through infrared absorption measure-
ment
(NDIR), air quality sensors deter-
mine the CO
₂
concentration.
And
because of an additionally integrated
reference light source, they can also
periodically recalibrate themselves.
This ensures freedom from main
te-
nance, long-term stability and maximum
measuring accuracy. The sensors also
deliver immediately, precisely mea
-
sured values regardless of room occu-
pation.
Ultimately, you save substan-
tial start-up, service and operating
costs.
Comfortable and economical
installation in the air duct
Fast, secure and cost-efficient installa-
tion –
with no need for additional duct
installation housing or sealing mea-
sures: The
installation of air duct sen-
sors is very easy
thanks to their ergo-
nomic, installation-
friendly 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, align
ment with
the flow direction is no longer
needed.
Two totally separate chambers for
mea-
surement modules and connection
ter-
minals 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.
