MEASUREMENT CONSIDERATIONS

Instrument Compatibility

The 80PK-3A is designed to be 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 could be considered along with the 80PK-3A accuracy specification in order to determine the overall accuracy of the combination.

Temperature Limitations

The probe tip has a continuous temperature rating of 260°C. However the rest of the assembly is rated for a lower temperature. See the specifications for further information.

Media Limitations

The Type K thermocouple junction is compatible with clean oxidizing atmospheres.

Applications information

At high temperatures, a surface temperature probe removes a small amount of heat from the measured surface. At 260°C on a polished metal surface, the temperature at a contact point will be lowered, typically not more than 2°C. Low temperatures at the contact point are less likely, and contact response time is quicker, on polished metal surfaces than on materials with low thermal conductivity, such as plastic and rough or contaminated surfaces. To obtain the best thermal contact and performance, the white supporting ring must make full and firm contact with the measurement surface.

OPERATION

Use the 80PK-3A as follows:

1.Connect the 80PK-3A to a compatible type K temperature measuring instrument using the miniature 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 bead, the measuring instrument should display the ambient (room) temperature. If the instrument does not read out properly, refer to the TROUBLESHOOTING section below.
