  • Thermocouple Compensation Wire

    The thermocouple compensation wire is used to extend the hot electrode, that is, to extend the cold end of the thermocouple, and to connect with the display instrument to form a temperature measurement system. It is usually composed of compensation wire Alloy Wire, insulation layer, jacket and outer sheath.

    The thermocouple compensation wire can be divided into two kinds according to the tolerance of thermoelectric characteristics: precision and ordinary. According to the use of temperature range is divided into general use and heat resistant. According to the structure, it is divided into single strand core and multi-strand core two.
