Omega HX93A RH/Temperature Transmitter
Wall, Duct Mount and Remote Probe Model
The Omega HX93A transmitter provides remote or on-site
monitoring of relative humidity and temperature. The HX93A outputs a
linearized current or voltage signal proportional to the measured humidity
or temperature. RH outputs are temperature compensated. Current output
models enable placing of the transmitter at a remote location virtually
any distance away from the readout or datalogging
device. The Omega HX93A utilizes a thin-film polymer capacitor to
sense relative humidity, and a Platinum 100RTD to accurately sense
temperature. A stainless steel mesh type filter protects the sensors,
which is easily removable for cleaning. Mounting screws are easily
accessible inside the rugged, ABS enclosure, which houses and protects the
electronics to NEMA 13 specifications. An unregulated
power supply providing a voltage of 6-30V powers the HX93A.
