4. Design and function
Description
The sensor changes its conductivity in proportion to the number of
molecules of reduced gases. The associated output voltage of the
measuring element is correspondingly increased from DC 0 ... 10 V.
The greater the output signal of the sensor (0 ... 10 V), the worse the air
quality. Mixed gas sensors are wide band, i.e. the sensor signal does
neither show the type of gas nor the concentration in ppm. The sensor
cannot distinguish pleasant from unpleasant smells, but in the end it is
the persons living or working in the room who have to judge whether the
air quality is satisfactory or not.
Scope of delivery
Cross-check scope of delivery with delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the air quality sensor for any damage that may have been caused
during transportation. Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during trans-
port (e.g. change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -20 ... +50 °C
Protect the instruments from moisture and dust.
