Product Description

Uses of Siemens® QFA 2071 Temperature and Humidity Room Sensor:

  • To monitor Relative Humidity, Temperature in ventilating, and air conditioning plants to acquire.
  • The Temperature and Humidity Room Sensor is used as a Control sensor
  • Siemens® QFA 2071 is used as a measuring sensor for indicating units or building automation and control systems.

Relative Humidity: The sensor acquires the relative humidity in the room via its capacitive humidity sensing element whose electrical capacitance changes as a function of the relative humidity. The electronic measuring circuit converts the sensor’s signal to a continuous DC 0 to 10 V or 4 to 20 mA signal, which corresponds to 0 to 100 % relative humidity
Temperature: The sensor acquires the temperature in the room via its sensing element whose electrical resistance changes as a function of the temperature. This change in resistance is converted to an active DC 0…10 V or 4…20 mA output signal, corresponding to a temperature range of 0 to 50 °C, –35 to +35 °C, or -40 to +70 °C. The measuring range can be selected. The temperature is provided as a simulated passive LG-Ni 1000 or T1 output signal ( 0 to 50 °C) as an alternative to the active output signal.
