MODEL TMP - FIELD CUTTABLE TEMPERATURE SENSOR PROBES
AND ACCESSORIES

GENERAL DESCRIPTION

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

WIRE COLOR
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.
