High Quality Thermocouple electric cable alloy Wire N Type NP/NN Nickel chrome silicon- Nickel silicon magnesium tnermocouple sensor copper wire
Product Description
Thermocouple compensating wire is used to connect the electrode (cold side of thermocouple) with display instrument in order to form a temperature measurement system.
Thermocouple compensating wire is used to extend the reference junction of thermocouple and connect with the temperature measuring instrument to form a temperature measuring system.
It usually works in most applications, which include industrial aerospace,nuclear power,chemical industry.
