Thermocouple Immersion Errors

Source

An attempt has been made to distinguish between two types of “immersion” errors. The first type occurs when an inhomogeneous portion of a thermocouple (developed, perhaps, at the service temperature) is subjected to a temperature gradient. The second type of “immersion” error is related to conduction of heat to or from the hot junction of the thermocouple. Both of these “immersion” errors are directly related to the thermocouple material and its temperature surroundings. Poorly operating control and measuring systems will not cause these errors, nor will the best instrumentation reveal them.
