Siem ens Indoor air quality sensors QPA10.., QPA20.. CE1N1961en
Building Technologies 2018-05-01
Typical use:
· Acquisition of CO
2
and VOC concentrations:
In party rooms, lounges, fair pavilions and exhibition halls, restaurants, canteens,
shopping malls, athletic centers, sales rooms, and conference rooms.
· Acquisition of CO
2
concentrations:
In rooms with varying occupancy levels where smoking is prohibited, e.g. museums,
theaters, movie theaters, auditoriums, office spaces, and school rooms.
QPA20… sensors may not be deployed as safety devices, e.g. as gas or smoke warn-
ing devices!

Ordering
When ordering, please give name and product number, e.g.:
Room air quality sensor QPA2002
Equipment combinations
All systems and devices capable of processing the following sensor signals:
· DC 0...10 V or DC 0...5 V or 4...20 mA passive sensor signals for sensor QPA2080…
Mode of operation
Symaro
TM
air quality sensors acquire the CO
2
concentration by infrared absorption
measurement (NDIR).
The resulting output signal DC 0...10 V or DC 0...5 V or 4...20 mA is proportionate to
the CO
2
content of ambient air.
