how to use K thermocouple instead E- type without
compesation cable
Answer Posted / carl_ellis
Any thermocouple measuement requires 2 temperature measurements
- hot junction measurement
- cold junction measurement
A cold junction is created at the point where
non-compensation wire is connected to the thermocouple wire.
A measurement without compensation wire AND without a
corresponding cold junction measurement is not valid.
The only way to take a K type thermocouple measurement (or
any type thermocouple measurement) without compensating
cable is to use a temperature transmitter configured for the
type of thermocouple because the transmitter will perform
the cold junction measurement at its wiring terminals.
