The Telaire EHRH Humidity Transmitter is a waterproof RH sensing element
and package which is ideally suited for monitoring relative humidity in high RH/harsh environment
applications or where washdowns are required. The EHRH relative humidity / temperature transmitter
is designed for continuous monitoring of relative humidity and temperature and is available in
±2% accuracy.
The EHRH relative humidity / temperature transmitter's sensor and electronics are contained in an
epoxy-hardened enclosure designed for continuous service. A water-tight membrane filter is
installed over the RH sensor for increased protection against high RH, contaminants and
washdowns. The EHRH is designed
to withstand 100% saturation. The sensor incorporates a bulk polymer resistance element. The
polymer is impervious to most contaminants and, since it is a bulk resistance device, surface
contamination such as dust will not alter the accuracy of the readings.
The EHRH is provided with
continuous temperature compensation which adjusts for temperature-induced change in the
RH sensor output. The compensation provides high measurement accuracy over the entire
operating range of the instrument.
