for capacitive acquisition of relative air humidity. The humidity sensor element used for this instrument excels by high long-time stability, nearly linear characteristics, good dynamic response, dewing resistance and small hysteresis. The electronic incorporated in the transmitter case supplies a linear output signal. A PT 100 resistance thermometer with four-wire-type direct output serves for temperature measurement.

Weather and radiation protected hut for adapting the humidity and temperature transmitter.
