INTRODUCTION
The single point strap-on temperature sensor utilizes a precision
sensor that is attached to a 38 mm x 38 mm (1.5”x 1.5”) aluminum plate
and adhered to a 38 mm x 25.4 mm (1.5 x 1“) compressible foam. 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
Readtheseinstructionscarefullybeforeinstallingandcommissioning
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.
• All thermistors and most RTD's are a two wire hook up and are not polarity sensitive. See Figure 6.
• For RTD's that are three wire 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.
