Thermocouple extension cables are designed specifically for use as lead wires of thermocouples.Thermocouples normally use a pair of rare metals, such as Chromel-Alumel, Platinum-Rhodium, etc., which can be very costly if used over a long distance. Thermocouples use solid wires, which inherently provide limited flexibility, and the conductor resistance can significantly increase over a long length. To solve such problems, thermocouple extension cables are offered for connection between thermocouples and corresponding measuring instruments.
Therefore, thermocouple extension cables must offer the following features:
Fujikura offers thermocouple extension cables compatible with various types of thermocouples.
