KEI offers Thermocouple Extension and Compensating. These cables are also called instrumentation cables, as they are used for process temperature measurement. The construction is similar to paired instrumentation cable but the conductor material is different. Thermocouples are used in processes to sense temperature. It is connected to the pyrometers for indication and control. The thermocouple and pyrometers are electrically conducted by thermocouple extension/compensating cables. The conductors used for these cables are required to have similar thermo-electric properties as that of the thermocouple used for sensing the temperature.
