Compensation for thermocouple extension wire is used to heat the electrode that is moving the thermocouple cold junction, and display temperature meter connection constitutes a system. This product uses the GB / T 4989-94 "thermocouple compensating cables, " the national standard (equivalent with IEC584-3 "Thermocouple Part III - compensation wire"international standard), insulation layer And fluorine sheath imported high quality plastic, and the overall continuous extrusion using new technology, so that the product has good acid and alkali, wear resistance and extend the performance of non-combustible, can be immersed in water long-term use. Temperature -60-205-260 ℃, is the contemporary international advanced level. Products are mainly used in various temperature measurement devices, has been widely used in petroleum, chemical, metallurgy, electric power sector。
