1) With insulated on a pair of conductors almost same EMF with thermocouple from low temperature to high temperature,
Connect between the terminal of thermocouple and measuring point with wire.
To compensate error of temperature change on terminal of thermocouple is Compensating Wire.
2) The wire made by same material of thermocouple is called Extension Wire.
