GENERAL DESCRIPTION

Model TMP Thermocouple and RTD Temperature Probes are field cuttable
to the desired length. The probes can be trimmed to within 3.5" (88.9 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. The
spring loaded fittings are adjustable and reusable.

There are no standard wire

colors for RTD probes. When
connecting the RTD wiring,
two wires are the same color
and one is a different color.
The two wires of the same
color connect to signal (+)
and excitation (+). These two
wires are interchangeable.
The other wire connects to
signal common.

ORDERING INFORMATION

ACCESSORIES (All accessories are sold separately)

Note: One tube sleeve is included with each probe.

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 within 3.5" (88.9 mm) of the tip.

1. Determine the desired length of the probe and mark with a pen or marker.

Secure the probe within a tube vice being careful not to deform or flatten the

probe.

2. “Score” the tubing with a tubing cutter. Make one or two revolutions with the

cutter. Do not cut completely through the tubing to prevent burrs or a sharp

lip on the inside of the tubing.

3. Use a pair of pliers to grasp the excess tubing to be removed.

4. Use a narrow range of motion to slowly work the excess tubing from side to

side until it separates from the probe. Using a wide range of motion will

deform the tube and prevent installation of the tube sleeve.

5. Remove the excess tubing and trim the leads to the desired length.

6. Install the tube sleeve in the open end of the tube to protect the leads from

any sharp edges on the inside of the tube.

INSTALLATION

1. Orient the probe and the spring loaded fitting as shown below.

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 below 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 go in
the wrong direction.
