Siem ens Indoor air quality sensors QPA10.., QPA20.. CE1N1961en
Building Technologies 2018-05-01
The sensor acquires the room temperature with a sensing element whose electrical
resistance changes as a function of the temperature.
The change is converted to an active DC 0...10 V or DC 0...5 V or 4...20 mA output
signal
( 0...50 °C or - 35...+35 °C).
The sensor measures the room temperature using a sensing element where electrical
resistance changes with the temperature of the ambient air.
The sensing element is on the device's rear side and connected at the appropriate
connection terminals.
The following sensing elements are included with the device:
- LG-Ni1000
- Pt1000
- Pt100
- NTC 10kOhm
