THERMOCOUPLE OR RTD
24" PROBE CUTTABLE TO 3" (76 mm)
MEASURE TEMPERATURES UP TO 1000 °F (538 °C)
MOUNTING AND WIRING ACCESSORIES
GENERAL DESCRIPTION
Model TMP Thermocouple and RTD Temperature Probes are field cuttable to
the desired length. The probes can be trimmed to within 3" (76 mm) of the probe
tip allowing for greater application flexibility. Accessory hardware is available
to wire and mount the probes in the user's existing thermowell.
Optional spring loaded fittings (sold separately) slide along the probe sheath
to proper immersion depth as determined by the user. These fittings allow for
strong contact between the probe and the thermowell to improve response.

CUTTING THE TUBING
The thermocouple and RTD probes have a crimp mark located 3" (76.2 mm)
from the tip. This indicates the end of the internal seal. Damage to the probe will
occur if trimmed less than 3" from the tip.
1. Determine the desired probe length and mark it with a pen or marker. Secure
the probe within a tube vice being careful not to deform or flatten the probe.
2. Use a tubing cutter to cut the sheath at the marked location. Be careful not to
cut or damage the sensor wires.
3. Remove the excess tubing and trim the wires to the desired length.
4. Install the tube sleeve in the open end of the tube to protect the wires from
any sharp edges on the inside of the tube.
INSTALLATION
1. Orient the probe and the spring loaded fitting as shown above.
2. Screw the spring loaded fitting one complete turn into the thermowell (not
included).
3. Push the probe into the fitting until it touches the bottom of the thermowell.
4. Hold the probe to the bottom of the thermowell and tighten the fitting. This
ensures good contact between the probe and the bottom of the thermowell.
5. Completely tighten the fitting into the thermowell.
Note: The probe must be inserted only as shown above to prevent damage to
the fitting.
If it becomes necessary to separate the probe and the fitting, first disconnect
the wires and then unscrew the fitting completely from the thermowell. Pull the
probe through the fitting from the end that was screwed into the thermowell. The
fitting will present resistance to the probe removal if you attempt to remove it
from the wrong direction.
