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.

SPECIFICATIONS

Type: K (Chromel vs Alumel)

Measurement Range: 0°C to 260°C (32°F to 500°F)

Junction Accuracy: (With respect to ANSI MC96.1): ±2.2°C

(3.96°F) over the range of 0°C to 260°C (32°F to 500°F)

Restrictions: The 260°C continuous temperature rating is primarily

determined by the Teflon support piece. The Teflon insulation

should not be exposed to temperatures exceeding 260°C (500°F)

nor to open flame, since this can cause release of toxic material.

Output: 25°C (77°F) =1.00 mV (reference junction at 0°C)

Seebeck Coefficient: 25 °

C (77°F) = 40.50 µV / °C

Measurement Time: (Time Constant): 3 sec typical on metal

surface; 15 sec max. for a 260°C change. See Applications

Information below.

Maximum Voltage: 24V ac rms or 60V dc

Probe Tip:

Maximum Temperature: 260°C (500°F)

Material: White PTFE
