Section 1 - General Description
The OMEGA®HX93B and HX93BD Series Temperature/Relative Humidity
Transmitters 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 for both temperature/relative humidity measurement. The output
signals have been calibrated and scaled –30ºC to 75ºC for temperature and 0
to 100% for relative humidity. The digital temperature and relative humidity
sensorisprotectedbyastainlesssteellter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 HX93BD Series has a dual display with backlit to display both Temperature
and Relative Humidity readings. An on-board slide switch allows the user to
changethetemperaturereadingfrom°Cto°Fasshowningure1-1below.
Figure 1-1. Transmitter Internal Diagram
Most of the models come with a replaceable sensor probe; the process of
replacing the sensor probe is very simple using an M12 connector. See the
“Maintenance” section for details.
The models with a replaceable Sensor Probe are:
HX93BDC, HX93BDV0, HX93BDV1, HX93BDV2, HX93BDC-RP1, HX93BDV0-
RP1, HX93BDV1-RP1, HX93BDV2-RP1, HX93BC, HX93BV0, HX93BV1,
HX93BV2, HX93BC-RP1, HX93BV0-RP1, HX93BV1-RP1, HX93BV2-RP1.
The models without a replaceable sensor probe are:
HX93BDC- D, HX93BDV0-D, HX93BDV1-D, HX93BDV2-D, HX93BC-D,
HX93BV0-D, HX93BV1-D, HX93BV2-D.

Section 3 – Electrical Connection and Temperature Measuring
Range Selection
All electrical connections and wiring should be performed by a
suitably trained professional only.
3.1 Electrical Connection
Followtheelectricalconnectiondiagramshowningure3-1belowtosetup
your Temperature/Relative Humidity Transmitter.
Figure 3-1 Electrical Connection Diagram
3.2 Temperature Measuring Range Selection:
ThetemperaturemeasuringrangeoftheHX93Bcanbemodiedbymaking
a minor change to a connector J4. The standard temperature measuring range
is -30 to 75°C (-22 to 167°F) without adding any jumper on connector J4. If
you would like to change the range to -20 to 75°C (-4 to 167°F), add a jumper
on connector J4 pin 1 to pin 2. See the diagram below for the location of the
connector and its pins.
