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.
