Display Model Indicates Both Humidity & Temperature At The Same Time
The HX93A has been superseded, please see the HX93B Series as a possible substitute or consult OMEGA's Engineering department.
The HX93AC and HX93DAC transmitter provides remote or on-site monitoring of relative humidity and temperature. Both series output a linearized current or voltage signal proportional to the measured humidity or temperature. The HX93DA Series features dual built-in displays for local indication of both humidity and 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. Units utilizes a thin-film polymer capacitor to sense relative humidity, and a Platinum 100 Ohm RTD 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. A regulated power supply providing a voltage of 6-30V powers the HX93AC. An unregulated power supply providing a voltage of 12-24V powers the HX93DAC.
