    Thermocouple copper wire Classification

     

    • Thermocouple level (high temperature level). This type of thermocouple wire is mainly suitable for thermocouple type K, J, E, T, N and L and other high temperature detection instrument, temperature sensor, etc.
    • Compensating wire level (low temperature level). This type of thermocouple wire is mainly suitable for compensating cable and extension wire of various thermocouples of type S, R, B, K, E, J, T, N and L, heating cable, control cable and so on.
    • The products is manufactured according to the standards of GB/T4989-1994 Compensating Wire for
    • Thermocouples and JB/T7495-1994 Compensating Cable for Thermocouples.
    • This kind of products are mainly used as the connect wire in the automatic measure instruments in the
    • electronic power industry, chemical industry, petroleum industry, metallurgy industry and national defense industry, etc.
