80PK-3A
Type K Thermocouple Surface Probe
Instruction Sheet
WARNING
TO AVOID ELECTRICAL SHOCK, DO NOT USE THIS PROBE
WHEN VOLTAGES EXCEEDING 24V AC RMS OR 60 V DC ARE
PRESENT.THE PROBE TIP IS ELECTRONICALLY CONNECTED
TO THE OUTPUT TERMINALS.
CAUTION
The thermocouple strip in the tip of the probe is designed to
deflect only .030” in normal operation. Any action which bends
or pulls the strip out further from the tip will CONSIDERABLY
reduce the life of the probe
INTRODUCTION
The 80PK-3A Type K Thermocouple Surface Probe is designed for
measuring the temperature of flat or slightly convex surfaces, with
an exposed junction to allow direct contact with the surface being
measured. The 40-inch (1-meter) cable is terminated with a Type K
miniature thermocouple connector with 0.792-mm (0.312 in) pin
spacing. The probe can be used with any temperature-measuring
instrument that is designed to accept type K thermocouples and has
a miniature connector input.
