Product information "Siemens Duct Sensor for Temperature & Humidity – QFM2171"
Siemens Duct sensors for measuring relative humidity and temperature in air ducts of ventilation and air conditioning.
The sensors are used as:
- Control sensors in the supply or extract air.
- Reference sensors, e.g. for shifting the dew point
- Limit sensors, e.g. in connection with steam humidifiers
- Limit sensors, e.g. for measured value indication or for connection to a building automation and control system
- Sensors for enthalpy and absolute humidity, together with SEZ220 (Ref datasheet N5146)
