RH/Temperature Transmitter

1. General Description

The OMEGA® HX93A and HX93DA Series Relative Humidity/ Temperature Transmitter’s provide a linearized and temperature compensated output signal of 4 to 20 mA or 0 to 1 Vdc depending upon the model selected for both relative humidity and temperature measurement. The output signals have been calibrated and scaled 0 to 100% for Relative Humidity and –20 to 75ºC for temperature. A thin film polymer capacitor senses relative humidity while an 100 ohm RTD measures temperature, both are protected by a stainless steel filter that is easily removed for cleaning. The Nema rated polycarbonate enclosure and cable entry connection provides weathertight protection. Screws are provided for mounting via internal holes inside the enclosure. The HX93DA Series has dual built-in indicators for humidity and temperature.
