Thermocouple Mounting
The thermocouple included in the kit comes with a stainless steel compression style
mounting adapter. The mounting adapter consists of three pieces: compression nut,
ferrule sleeve, threaded body. Th
e threaded body has 1/8” NPT male threads. To
install the sensor, the threaded body can either be threaded into a hole with mating 1/8”
NPT threads, or welded to the pipe/manifold. Remove the compression nut, ferrule
sleeve, and thermocouple from the threaded body. For a welded installation, drill a
13/32” hole and weld the threaded body, being careful not to cause any distortion. .
For a threaded installation,
either thread the body into an existing hole with 1/8” NPT
threads or drill a hole using a n “R” size drill bit and cut the threads using a 1/8” NPT tap.
With the compression nut and ferrule sleeve on the thermocouple, insert the
thermocouple into the threaded body so the tip of the thermocouple is near the center of
the pipe/manifold and tighten the compression nut to the threaded body.
Connecting the Thermocouple
Slide the supplied heat shrink onto the sensor cable. Connect the RED wire from the
thermocouple to the RED wire on the harness and the YELLOW wire from the
thermocouple to the YELLOW wire on the harness using the supplied 4-40 screws and
hex nuts. Make sure the connections are not touching. Center the heat shrink over the
connections and apply mild heat to the heat shrink until it shrinks over the connections.
