Measurement Considerations
Instrument Compatibility
The 80PK-27 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 must be considered along
with the 80PK-27 accuracy specifications in order to determine
the overall accuracy of the combination.
Temperature Limitations
The probe tip has continuous temperature rating of 600 °C.
However the rest of the assembly is rated for a lower
temperature. See the specifications for further information.
Media Limitations
Media must be compatible with Chromel, Alumel, and 303
stainless steel.
Application Information
At high temperatures, a surface temperature probe removes a
small amount of heat from the measured surface. At 600 °C on
a polished metal surface, the temperature at a contact point
will be lowered, typically not more than 2 °C. A lowering of the
temperature at the contact point is less likely (and contact
response time is quicker) on clean, polished, thermally
conductive surfaces than on materials with low thermal
conductivity, such as plastic or rough, contaminated surfaces.
To obtain the best thermal contact and performance, the
stainless steel ring must make full and firm contact with the
measurement surface.
