General Description

Section 1 - General Description
The OMEGA ® HX92B Series Relative Humidity Transmitter provides a
linearized and temperature compensated output signal of 4 to 20mA, 0 to 1 Vdc,
0 to 5 Vdc or 0 to 10 Vdc depending upon the model selected. The output signals
have been calibrated and scaled 0 to 100% Relative Humidity output scale. The
digital Relative Humidity sensor is 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 terminal connection for the
output signal is as shown in Figure 1-1 below.
