The working principle of tungsten-rhenium thermocouples compensation conductor _ instrument

Tungsten rhenium thermocouple compensation wire at a certain temperature range, and electric properties of thermocouple same pair with insulation layer and protective conductor is called compensation conductor. Its role is to extend to the far away from the heat source of the reference junction of the thermocouple or ambient temperature is constant, and display instrument connection temperature measuring system. Tungsten rhenium thermocouple compensation wire electrode is used to extend heat namely mobile thermocouple cold end connected with display instrument of temperature measurement system. Compensation conductor should be general use on the thermocouple, thermocouple compensation wire insulation layer and protective layer selected materials according to the requirement of the environment and different, sheath material with PVC, fluorine plastic, low smoke low halogen polyvinyl chloride (PVC) and several non-alkali glass, imported high quality fluorine plastic can heat resistance of 260 ℃, and USES the new technology of the continuous extrusion, make the product has excellent acid, alkali, wear resistance and non-combustible delay of performance, can be immersed in oil and water medium and long term use. Tungsten-rhenium thermocouples compensation conductor temperature can in - 60 ~ 260 ℃, belong to contemporary domestic advanced level. Series products are mainly applied to all kinds of temperature measuring device, compensation conductor model according to the varieties of products are classified into WC3/25, WRe3 - WRe25、WC5/26 WRe5 - WRe26。 Tungsten rhenium thermocouple compensation wire products use characteristics: tungsten rhenium thermocouple compensation wire can be in - 60 ~ 260 ℃ environment, is the ideal automation units. Has been widely used in petroleum, chemical industry, metallurgy, electric power automation thermometer table of single point or multipoint connection.
