If your HX92B will be used in a dusty environment, the
protective sensor filter (if clogged) may be removed for
cleaning.
Unscrew the protective cover and gently blow
compressed air through the filter screen. A soft brush
may also be used to remove dirt particles from the
screen.

If the sensor is subjected to 100% condensation, it must
be dried to obtain correct readings. There will be no
permanent damage or calibration shift to the unit.
Units should not be exposed to high concentrations of
ammonia or alcohol vapors.
NOTE:
For the Duct Mount model Transmitter, it must be sent
back to factory for sensor probe replacement and
recalibration.
Calibration:
Your transmitter has been digitally calibrated and
tested in our factory to meet or exceed the specifications
outlined in this manual. The transmitter must be sent
back to the factory for any re-calibration request.

Using This Quick Start Manual
Use this Quick Start Manual with your HX92B
Series Relative Humidity Transmitter for quick
installation and basic operation. For detailed infor-
mation refer to the User’s Guide (Manual #M5339).
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 polycarbon-
ate enclosure and cable entry connection provides
weather tight protection. Screws are provided for
mounting via internal holes inside the enclosure.

Relative Humidity Output Calculations
To calculate % relative humidity by measuring
the current or voltage output, use the following
formulas:
For current output:
%RH = (Current measured in milliamps – 4) ÷ 0.16
Where:
4 = offset current in mA.
0.16 = full scale current limit in
percent (%)
For voltage output:
0 to 1 volt output:
%RH = (voltage measured in volts) x 100
0 to 5 volt output:
%RH = (voltage measured in volts/5) x 100
0 to 10 volt output:
%RH = (voltage measured in volts/10) x 100
