Room Humidity-/Temperature Sensor

The RRFT/A humidity and temperature sensor in modern room design housing measures the relative humidity 0...100% r.H. and the temperature of the ambient air by a capacitive sensor and transforms it to a linear output signal 0-10 V or 4-20 mA. The humidity and temperature transducer can be adjusted locally for fine calibration by an offset controller.
