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
