China 1X1.0mm2 KPCA KNCA Iron- Copper nickel 22 compensation extension alloy wire ?high temperature for thermocouple sensor electrical insluated cable thermometer

Product Description

KPCA KNCA Iron- Copper nickel 22 compensation extension alloy wire high temperature for thermocouple sensor electrical insluated cable thermometer

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.
