Combined sensor for the exact measurement of relative humidity and temperature, especially suitable for applications in agriculture and air conditioning. Application possibility in polluted atmospheres.
The sensor has a connection housing which contains the evaluation electronics.
The relative humidity is output by a 0 – 10 V signal. This corresponds to the measuring range of 0 – 100 % relative humidity. The temperature measurement is made by the change in resistance of the built-in PTC (Positive Temperature Coefficient) element (KTY81-210).
Resistance at 25 °C = 2 kΩ.
