The universal sensor with transducer measures the temperature and selectively the relative humidity, absolute humidity, air fuel ratio or dew point of the ambient air and transforms it to a linear output signal 0-10 V or 4-20 mA.
The secondary measuring value is selectable from the 4 measurement categories % r.H., g/m³, g/kg, TP by a DIP switch. The humidity and temperature sensor is protected against contamination by a screwable stainless steel sinter filter. The humidity and temperature transducer can be adjusted locally for fine calibration by an offset controller.
