Thermocouple Extension Compensating Alloy Wire For Type J Temperature With High Thermal EWF Range
Thermocouple Extension Compensating Alloy Wire For Type J Temperature With High Thermal EWF Range
Thermocouple extension compensating wires are essential for connecting thermocouples to measuring instruments while maintaining the accuracy of temperature readings over extended distances. For Type J thermocouples, which use Iron (Fe) for the positive leg and Constantan (CuNi) for the negative leg, JX extension wires are designed to extend the thermocouple leads while compensating for the thermoelectric properties of the original thermocouple materials.
