The CO2 measurement of the GMW80 series is based on a second-generation CARBOCAP® sensor, which uses a novel, microglow light source instead of an incandescent light bulb for a longer trouble-free lifetime. The internal reference in the CO2 sensor guarantees the best stability and operation also in constantly occupied buildings without frequent readjustments. The CARBOCAP® sensors give correct CO2 measurements immediately when powered on as they have a built-in reference measurement. Proper operation can be verified immediately after snapping on the device cover.
Easy installation
With modern buildings often having
hundreds of sensors, installation time per
unit can be a significant cost factor.
Returning to the building site to check
sensor operation adds further costs.The GMW80 series transmitters include a
number of subtle design features that
have been introduced to make
installation and commissioning quick and
easy.
The pull-out tab makes opening the
transmitter faster than before, while also
doubling as a quality check slip and
holder for the anti-tamper screw. The
backplate can be twisted onto premounted screws, and the wiring can be
done easily on the clearly marked
backplate. The electronics can be
snapped on later when the building
automation system is commissioned.
For measurements in more demanding
conditions (for example, dusty or humid
installation locations), the GMW87 and
GMW88 models provide an IP64-rated
enclosure with a cable gland
Reliable operation
The GMW80 series transmitters are
optimized for low maintenance. The
unique, low-power CARBOCAP
technology enables a longer lifetime and
better stability than ever before. As the
power consumption is low, the heat
generated by the electronics does not
distort the temperature inside the sensor.
The internal reference in the CO2
sensor
guarantees superior stability and flawless
operation even in constantly occupied
buildings, without the need for frequent
readjustments.
The reliable operation and accurate
measurement values of the GMW80
series transmitters contribute to the
significant cost savings brought by
demand-controlled ventilation.
