Siemens Duct Sensor for Humidity – QFM2100


Siemens QFM2100 Symaro™ Duct sensors for measuring relative humidity and temperature in air ducts of ventilation and air conditioning.

The sensors are used as:

i) Control sensors in the supply or extract air.

ii) Reference sensors, e.g. for shifting the dew point.

iii) Limit sensors, e.g. in connection with steam humidifiers.

iv) Limit sensors, e.g. for measured value indication or for connection to a building automation and control system.

v) Sensors for enthalpy and absolute humidity, together with SEZ220 (Ref datasheet N5146).
