Applications

The QFM21.. duct sensors are for use in air ducts of ventilation and air conditioning plant for acquiring:

  • The relative humidity and
  • The temperature.

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 (see Data Sheet N5146)
