INTRODUCTION
The high accuracy single point strap-on temperature sensor utilizes a precision
sensor that is attached to a 38.1mm x 12.7mm (1.5” x 0.5”) machined aluminum heat
sink. A 254 mm (10”) S/S Pipe clamp is provided to secure the assembly to various
sizes of pipe. All probes are constructed to provide excellent heat transfer, fast
response, and are potted to resist moisture penetration. 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 sensor. 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 space between immersion and sensor with thermowell can’t 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 a latch. Open the 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. E style
enclosure includes 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
• Use 18 - 24 AWG shielded wiring for all connections. 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.
• Pull at least six inches of wire into the enclosure, then complete the wiring connection according to wiring diagrams below.
• Thermistors are a 2 wire hook up and are not polarity sensitive. See Figure 6.
• RTD’s are a 3 wire hook up see Figure 7.

TYPICAL WIRE RESISTANCE VALUES
When using low resistance sensors, long wire runs can add signicant error
to the readings. Use the following chart to determine errors due to wire
resistance or consider using a 1000 ohm sensor or a transmitter for better
accuracy. Locate the type of wire being used. Multiply the total length of the
wire (distance from the controller to the sensor and back) by the number
found in the chart below for total resistance.

NOTE: The sensor accuracies listed in the specications section apply to the
sensing element only prior to product assembly and may not be reected in
the complete assembly.
Due to the measurement uncertainty, it is possible, that the true resistance
value of the single delivered sensor at 0°C can be out of the dened tolerance
class. Proling each assembly to take into consideration lead wire and the
attachment method should be completed.
