Siemens Smart Infrastructure - QFA2060 ROOM SENSOR FOR HUMIDITY AND TEMPERATURE, AC 24 V OR DC 13-35 V

The Siemens Smart Infastructure QFA2060 Room Humidity Sensor is designed for use in ventilating and air conditioning plants to determine relative humidity and temperature. It is used as a control sensor and measuring sensor for building automation and control systems or indicating units.

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...10 V or 4?20 mA signal, which corresponds to 0...100 % relative humidity.

The room sensors have been designed for wall mounting. They are suitable for use
with most commercially available recessed conduit boxes.
