INTRODUCTION
The high accuracy single point strap-on temperature transmitter has a precision
platinum RTD bonded to a 38.1 mm x 38.1 mm (1.5” x 1.5”) aluminum plate and
adhered to a 25.4 mm (1“) compressible foam. A 25.4 cm (10”) S/S Pipe clamp
is provided to secure the assembly to various sizes of pipes. All probes are
constructed to provide excellent heat transfer, fast response and are potted to
resist moisture penetration. A transmitter that provides a high accuracy signal
with excellent long term stability, low hysteresis and fast response is available
with various ranges. A compact ABS enclosure with a hinged and gasketed cover
is provided for ease of installation.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the
temperature transmitter. Failure to follow these instructions may result in
product damage. Do not use in an explosive or hazardous environment, with
combustible or ammable gases, as a safety or emergency stop device or in
any other application where failure of the product could result in personal
injury. Do not exceed the device ratings.
MOUNTING
The strap-on sensor installs directly onto any pipe where an immersion sensor with thermowell cannot be installed.
Once a suitable spot is selected, remove a small block of insulation, if present. It is recommended that thermal compound be used to improve
heat transfer. Spread a liberal amount on the pipe. Open the worm gear clamp by swiveling the worm gear away from the clamp and pull the
clamp apart, as shown in Figure 1.
Place the sensor plate on the selected mounting area and wrap clamp around the pipe. Re-insert
clamp under the worm gear and pull until snug. Lock in place by swiveling the worm gear towards
the clamp. Tighten worm gear clamp by using a standard screw driver or hex nut driver as shown
in Figure 2.
The enclosure has a hinged cover with latch. Open cover by pulling slightly on the latch on the right
side of the enclosure. At the same time pulling on the cover, as illustrated in Figure 3.
A 1/2" NPT threaded connection hole is provided in the bottom of the enclosure. Screw the EMT
connector or cable gland connector in until tight. See Figure 4. It is recommended that weatherproof
conduit or cable gland ttings be used. The E style enclosure includes a 1/2" NPT to M16 thread
adapter and cable gland tting.
Make wiring connections as per the “Wiring”illustrations on Page 2.
Swing door closed until securely latched. For added security, 2 screws are provided that may be
installed in the integrated screw tabs. See Figure 5.

WIRING
• Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent equipment damage.
• Use 14-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used to supply
inductive loads such as motors. Make all connections in accordance with national and local codes.
• The temperature transmitter comes with the temperature sensor pre-wired to the transmitter board. If removal is required for installation
then it may be re-wired as shown in Figure 6.
• Pull at least six inches of control wire into the enclosure, then complete the wiring connection according to the wire diagram for the
applicable power supply and output signal type as shown in Figure 7.
• Connect the DC positive or the AC voltage hot side to the PWR terminal. For voltage output or AC power, the supply Common is connected
to the COM terminal. The device is reverse voltage protected and will not operate if connected backwards. It has a half-wave power supply
so the supply Common is the same as the signal Common. See Figure 7.
• The analog output is available on the OUT terminal. Check the controller Analog Input to determine the proper connection before applying
power as shown in Figure 7.
• Once all connections are made and checked, power can be applied.
