H7531-2 Relative humidity, temperature and atmospheric pressure transmitter with Ethernet connection and COMET relays, 2 m cable

Description

H7531-2 relative humidity, temperature and atmospheric pressure transmitter with Ethernet connection and COMET relays, 2 m cable measures ambient temperature, relative humidity and atmospheric pressure. It has two relay outputs.

The sensor monitors the temperature and relative humidity of the air online, which is free of aggressive substances. Three binary inputs for detecting two-state signals are an advantage. Other devices are controlled by two relay outputs.

The high-precision H7531-2 capacitive polymer sensor provides excellent long-term calibration stability and ultimate accuracy. The measured values can also be converted into other interpretations of humidity: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.

The meter is equipped with a T+RH probe with a 2 metre cable.
