Air temperature and humidity – SHN

What is and what is used for

The air humidity sensor consists of a membrane of hygroscopic material that forms the dielectric of a capacitor so that the water molecules in the air are absorbed by the dielectric, thus causing a change in the capacitor’s capacity, due to the humidity, to which a change in the oscillation frequency of an electrical circuit connected to a sensor corresponds, which in turn transforms it into a change in direct voltage. The probe produces a signal/noise ratio.


The SHN transducer is a multiple sensor containing the transducers for measuring air temperature and humidity. The instrument consists of a “PT100 CI.A” thermistor according to the DIN 43760 standards to measure air temperature and a capacitive type of sensor to measure the relative humidity.
