Thermocouples Cables

Compensating or Extension Cables are used in temperature measurement to convey information from a thermocouple sensor, to the measuring instrument. The conductors are made of different metal to provide positive and negative cores to match the emf generated, from the sensor.

Extension wires, are having same materials as of thermocouple.
