dew point sensors

The dew point is an important measurand for many applications in the climate sector.

dew point sensor TPS-205

The dew point sensors can determine the dew point precisely due to the simultaneous measurement of temperature and relative humidity.

For the connection to measuring instruments and controls both the dew point and the temperature are provided as 0.5...5V and 0.5...10V signals.
