Sensing & Inspection Technologies Installation Guide
Warranty
GE Sensing & Inspection Technologies warrants equipment
of its manufacture to the original buyer against defective
materials or workmanship, for a period of one year for the
sensor tip and two years for the rest of the product, from the
date of shipment. The sensor element and calibration are not
covered by this warranty.
Calibration
All GE Sensing & Inspection Technologies RH/Dewpoint
and Temperature Products are fully tested and calibrated in
accordance with the National Institute of Standards and
Technology (NIST) prior to shipment. This is the highest
quality calibration standard available.
Power Requirements
12–30 VDC power supply (furnished by the customer).

Installation
For your convenience, the transmitters can be mounted
using the base as a mounting template (see Figure 1 or 2).
Wall Mount
Locate the transmitter where it will be exposed to an
unrestricted air circulation that is representative of the
average humidity and/or temperature of the controlled
space. Avoid locations where excessive moisture, corrosive
fumes, vibration, or high ambient temperatures are present.
The wall mount transmitter is designed to install onto a
standard electric switch box. Mount the transmitter on an
indoor wall approximately 4 to 6 feet above the floor. The
base assembly should be positioned with the letters FR/ABS
located on the left side.
Duct Mount
The transmitter should be mounted away from fans, corners,
heating and cooling coils, and other equipment that will
affect the measurement of relative humidity. It should be
mounted in a location that receives adequate air flow for
proper operation.
The duct mount transmitter should be mounted so that the
sensor probe is in the center of the duct.
Outside Air Mount
The transmitter should be mounted in a sheltered area that is
protected from rain. Ideally , the transmitter should be located
on the north side of the building (under an eave) to prevent
sun-heated air from rising up the building's wall and
affecting the relative humidity of the sensor.
The outside air mount transmitter should be mounted with
the sensor pointing down to prevent water collection in the
sensor cavity.
Sensing Element: Capacitive Sensor
Long Term Stability: Less than 1% drift per year, typical.
Temperature Effect:** Delta %RH =
(0.0014 x %RH + 0.1325) x T°C –
(0.0317 x %RH + 3.0876)
**Not needed for Signal-Conditioned Temperature units.
Signal Outputs: 4-20 mA, 0-5V or 0-10V (user selectable)

Sensing & Inspection Technologies Installation Guide
Wiring
Match your transmitter with the corresponding diagrams
(Figure 4 through Figure 9), set the switches and wire
accordingly. (See Figure 3 below for switch and terminal
block locations.) Ensure that all the installation and wiring is
in compliance with all national and local codes.
Note: All Voltage Outputs are measured with respect to the
POWER SUPPLY / CONTROLLER GROUND.
Wiring for the transmitter should be a shielded, twisted pair,
16-22 AWG. Use only copper conductors. Do not run
transmitter wires and AC power wires together in the same
conduit or wire bundle.
Caution!
Running transmitter wires and AC power wires,
including earth ground, in the same conduit or
wire bundle may cause malfunction due to
electrical noise.

CE COMPLIANCE
1. Ensure that the probe earth ground wire (for Duct and
Outside Air units only), the shield wire and the PCB earth
ground wire are connected to the mounting screw or the
NEAREST (<1.5m) earth ground.
2. The other end of the shield wire MUST be connected to
the power supply /controller earth ground ONLY.
