Mounting and Wiring

Immersion type probes are designed to measure the temperature inside pipes carrying liquid or steam. They are installed in a brass (for noncorrosive liquids) or 304 stainless-steel (for corrosive liquids) thermowell. Mount the thermowell horizontally or with the open end facing down, to allow any condensation to drain. Position the thermowell to prevent contact with the inside of the pipe. 

1. Install the pipe fittings required, by local code, for a thermowell into the dry/drained pipe. If the system is pressured, use a hot tap.

2. Install the thermowell. (See the Accessories section.)

3. Fill the well with thermal compound to ensure complete conductivity from well to probe. Note: The probe can slide within its collar on the case as it is inserted into the thermowell.

4. Remove the screws holding the cover to the case and remove the cover.

5. Insert the probe into the well and tighten the threaded connection on the case.

6. From inside the case, push the probe as far as it will go into the well.

7. Feed the thermistor wire leads through the conduit or hole opening. Note: The two-wire sensor is polarity insensitive.

8. Connect the thermistor wires to the cable with butt-splices or soldering (wire nuts are not recommended).

9. Reinstall the cover and screws
