Frequently Asked Questions - 80PK-22 FLUKE

What type of thermocouple is the 80PK-22?

The 80PK-22 is a Type K thermocouple (Ni-Cr vs. Ni-Al).

What is the temperature measurement range of the 80PK-22?

It measures from -40 °C to 1090 °C (-40 °F to 1994 °F).

What instruments are compatible with the 80PK-22?

Any instrument that accepts Type K thermocouples with a miniature connector and cold junction compensation.

What is the maximum voltage the probe can withstand?

The maximum voltage is 24 V ac rms or 60 V dc. Avoid exceeding this to prevent electrical shock.

Can the 80PK-22 be used in food or beverages?

No, it is not recommended for food or beverage preparation. Use the 80PK-25 for that purpose.

What is the sheath material and its dimensions?

The sheath is made of Inconel (Alloy 600), with a diameter of 3.175 mm (1/8 in) and length of 212.725 mm (8.375 in).

How deep should the probe be inserted for accurate measurement?

Insert at least 6.35 cm (2.5 in) into the medium to minimize thermal shunting.

What is the time constant of the probe?

The time constant is 3.0 seconds in 100 °C still water. Complete step change requires 5 time constants (3.75 seconds).

How do I clean and maintain the 80PK-22?

Clean with a damp cloth and mild detergent if needed. Avoid abrasive cleaners. Store in a dry place.

How can I check if the probe has a broken connection?

Use an ohmmeter to check continuity between the pins. A reading of 10 ohms or less indicates continuity.

USER MANUAL 80PK-22 FLUKE

To avoid electrical shock, do not use this probe when voltages exceeding 24 V ac rms or 60 V dc are present. The probe tip is electronically connected to the output terminals.

Introduction

The 80PK-22 SureGrip ^™ Immersion Temperature Probe is designed for use in liquids or gels. The probe can also be used as a general purpose temperature probe. The thermocouple junction is protected from tip to handle by an Inconel sheath. 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 80PK-22 can be used with any temperature-measuring instrument that is designed to accept Type K thermocouples and has a miniature connector input.

Note

The 80PK-22 is not recommended for use in food or beverage preparation. Use 80PK-25 for food preparation.

Measurement Considerations

Instrument Compatibility

The 80PK-22 is compatible with any temperature-measuring instrument that accepts Type K thermocouples, has a miniature thermocouple connector, and has cold reference junction compensation. Accuracy of the temperature-measuring instrument must be considered along with the 80PK-22 accuracy specification to determine the overall accuracy of the combination.

Temperature Limitations

The probe tip of the 80PK-22 has a continuous temperature rating of 1090^ (1994 °F). However the opposite end of the sheath nearest the handle should not be subjected to temperatures greater than 125^ (257 °F). This is the maximum temperature limitation of the handle.

Media Limitations

The sheath material of the 80PK-22 is Inconel, an alloy of chromium and nickel. It has excellent resistance to oxidation and corrosion at high temperatures, but it should not be used in the presence of sulfur above 537^ (1000 °F).

Operation

Use the 80PK-22 as follows:

1. Connect the 80PK-22 to a compatible Type K temperature measuring instrument using the miniature (0.312-inch pin spacing) thermocouple connector.
2. Turn on the measuring instrument, and select the appropriate range and scale.
3. Check the readout on the measuring instrument. With no heat or cold source applied to the tip of the probe, the measuring instrument should display the ambient (room) temperature. If the instrument does not read out properly, refer to "Troubleshooting".

Minimizing Thermal Shunting

The 80PK-22 Immersion Probe should be inserted at least 6.35 cm (2.5 in) into the environment to be measured to minimize the shunting effect of the sheath.

1. If you suspect a broken connection, use an ordinary ohmmeter to read the continuity of the probe from pin to pin. The ohmmeter should read 10 ohms or less if there is continuity.

Scale Conversions

Use the following equation to convert °C to °F:

$$ (^ {\circ} \mathrm{C} \times 1. 8) + 3 2 = ^ {\circ} \mathrm{F} $$

Use the following equation to convert °F to °C:

$$ (^ {\circ} F - 3 2) \times 0. 5 5 5 6 = ^ {\circ} C $$
