Siemens Duct Sensor

The Siemens duct sensor is a reliable and accurate sensor designed for use in air ducts of ventilation and air conditioning systems. It is specifically used for acquiring the relative humidity and temperature in these systems. With an operating voltage of AC 24 V / DC 13.5 to 35 V, the duct sensor offers various signal output options including DC 0 to 5 V, DC 0 to 10 V, and 4 to 20 mA for both relative humidity and temperature measurements. It provides excellent measuring accuracy within the comfort range of ±3% r.h. and has a wide range of use from -15°C to +60°C / 0-95% r.h.

Suitable for control, reference, and limit sensor applications
Can be used for enthalpy and absolute humidity measurements with SEZ220
Easy installation with supplied mounting flange and cable entry gland
