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.
