Duct humidity sensor active with passive temperature sensor

Product information "Duct humidity sensor active with passive temperature sensor"

Duct humidity and temperature sensor with active humidity sensor (4-20 mA or 0-10 V output signal) and freely selectable passive temperature sensor. The output signal of the humidity sensor is proportional to the humidity and can be selected as a voltage signal (0.10 V) or current signal (4-20 mA) using a jumper. The humidity transmitter impresses with its high accuracy and long-term stability and is therefore particularly suitable for building and industrial automation. The use of a capacitive polymer sensor with temperature compensation ensures particularly high accuracy. The temperature is recorded via a passive temperature sensor (selectable in the selection list).
