Installation, Continued
3. Using an abrasive tool, clean the surface of the
pipe where the sensor is to be mounted to
ensure good contact with the pipe. See Figure 2.
Figure 2. Pipe Temperature Sensor.
4. Bend the sensor wires back along the pipe next
to the sensor for strain relief. See Figure 2.
5. Secure the sensor to the pipe with 1-1/2 to three
wraps of the stretch tape provided. Stretch the
tape about 25% as you wrap it around the pipe.
See Figure 2.
6. Wrap the excess sensor wires around the pipe
and secure with the stretch tape or duct tape.
See Figure 2.
7. Replace the insulation removed in Step 1, and
secure it to the pipe with duct tape.
NOTE: If the pipe is not insulated, wrap a
piece of insulation around the sensor
and the pipe (see Prerequisites). The
insulation should be secured to the
pipe using duct tape to ensure
accuracy.
Wiring
1. Position the junction box on top of the pipe
insulation and feed the sensor wires into it from
the bottom of the box. The box should be
positioned so that the sensor wires come
straight up into the junction box from the seam in
the reinstalled insulation.
2. Thread the strap through the junction box and
attach the junction box to the pipe. See Figure 3.
Figure 3. Attaching the Junction Box and
Connecting the Sensor Wires.
3. Connect the electrical conduit, with the field
wiring, to the junction box.
4. Using two of the wire nuts provided, connect the
sensor wires to the field wires. See Figure 3.
5. Put all the excess wire into the junction box and
install the cover on the box.
6. Connect the field wires to the applicable
controller. See Figure 4.
Figure 4. Typical Sensor Connection.
NOTE: Configure the analog input (AI) point for
sensor input.
