Thermocouple, extension and compensating cable

In some applications, a thermocouple is located in a pipeline distanced from a measuring instrument in a control center. The thermocouple signal therefore sometimes runs through an entire factory. In these cases, lower-priced material is required in order to transmit the signal from a thermocouple to a measuring instrument. The inexpensive alloys used for thermocouple compensating cables slightly differ from the actual more expensive thermocouple alloy. Kamet uses three different grades for cable; thermocouple grade, extension grade, and compensating grade.

Extension cable grades we offer

Kamet has a wide range of thermocouple, extension and compensating cable for all types of thermocouples. Thermocouple extension and compensating cables are usually insulated with material varying from PVC, Silicon, PTFE, MFA, PFA and Fiberglass. The extension and compensation cables have flexible insulation material, so it can easily be installed at sites with many bends.

Special dimensions or customized designs such as multipair cables can be produced upon request.

Thermocouple grade

Thermocouple grade means the alloy is exactly the same as the alloy in the temperature sensor and therefore functions similar as a thermocouple.

Extension grade

Extension grade compensating cables have the same nominal composition of a thermocouple cable, but are calibrated as class 1 up to 200°C in accordance with DIN 43710.

Compensation grade

Compensation grade compensating cable has a different nominal composition than thermocouple cable. They can be recognized with character C.
