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.
SPECIFICATIONS
1. THERMOCOUPLE: Ungrounded J, K, T and E calibration available.
2. RTD: 3 Wire, 100
Ω, Class “A” DIN Platinum per IEC751 (385 ALPHA)
3. PROBE SHEATH: 0.25" (6.35 mm)
4. PROBE LENGTH: 24" (0.6 M) as supplied, can be field cut down to 3.5"
(88.9 mm).
5. LEAD WIRE: 6" (152.4 mm) 24 gauge
6. WIRE INSULATION: Neoflon PFA, Fiberglass or High Temperature Glass.
As specified by part number.
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 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. “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 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 go in the
wrong direction.
