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 carrier will not honor any damage claims unless all shipping material is saved for inspection. After examining and removing contents, save packing material and carton in the event reshipment is necessary. The following items are supplied in the box with your HX92B Series transmitter. • HX92B Series Quick start Manual, MQS-5339 (1 ea.) • #6 Wall Anchor and #6 Mounting Screw (2 ea.)

Theory of Operation and Electrical Connection Section 3 – Theory of Operation and Electrical Connection 3.1.1 Theory of Operation A 4 to 20 mA loop is a series loop in which a transmitter will vary the current flow depending on the input to the transmitter. In the HX92B the amount of the current allowed to flow in the loop will vary depending on the relative humidity being measured by the sensor. Some advantages of a current output over a voltage output is that the signal measured is less susceptible to electrical noise interference, and the loop can support more than one measuring instrument as long as the maximum loop resistance is not exceeded.

Mounting Section 4 - Mounting The HX92B transmitters are designed for wall, duct or remote probe mounting depending upon the model. Plastic wall anchors and mounting screws are included with Wall Mount and Remote Probe models. A duct mounting kit is included with Duct Mount models.
Relative Humidity Output Calculations Section 5 - 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.

Calibration Section 6 - Calibration Your transmitter has been digitally calibrated and tested to meet or exceed the specifications outlined in this manual in our factory. The transmitter must be sent back to the factory for any re-calibration request.
Maintenance Section 7 - Maintenance The sensor probe can be replaced quickly for Wall Mount and Remote Probe models. Procedure to replace the sensor probe: a. Loosen the securing nut, and pull the sensor probe out. b. I nsert the new sensor probe to the M12 connector, and tighten the securing nut to secure the connection.
