Maintenance; Figure 8-1 Sensor Probe Replacement - Omega HX93B Series User Manual

Section 8 - Maintenance
The Sensor can be replaced quickly for the wall mount and remote models.
Procedure to replace the Sensor:
a. Loosen up the Sensor Probe nut, and pull out the sensor probe.
b. Insert the new sensor probe to the M12 connector, and tighten the secure nut
to secure the connection.
If your Humidity transmitter is 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.
For the Duct mount model Transmitter, it must be sent back to factory for
sensor re-placement and re-calibration.
