Grounded junction with shielded cable
Metal sheath with electrical
continuity to thermocouple
signal wires.
Exposed Junction Thermocouples
As shown in the illustration that follows, using exposed junction
thermocouples may result in removal of channel to channel isolation.
This may occur if multiple exposed thermocouples are in direct contact
with electrically conductive process material. To prevent violation of
channel to channel isolation:
