Using Thermocouple Junctions
To prevent violation of channel-to-channel isolation:
•
For multiple exposed junction thermocouples, do not allow the
measuring junctions to make direct contact with electrically
conductive process material.
•
Preferably use a single exposed junction thermocouple with
multiple ungrounded junction thermocouples.
•
Consider using all ungrounded junction thermocouples instead
of the exposed junction type.
