WR series of platinum and rhodium thermocouple

Overview WR series of industrial platinum-rhodium thermocouple is also called precious metal thermocouples as temperature measurement sensor, usually associated with temperature transmitter, controller and display instrumentation supporting the use of the composition process control system for direct measurement or control of Production process fluid, vapor and gases and solid surface temperature in the range of 0-1800 ℃. Platinum and rhodium thermocouple is a conductor connected at both ends of two different components of the synthesis loop, when the two junction temperature is not the same, it will generate heat within the loop current. If the working end of the thermocouple and reference junction temperature difference, the meter will display instructions thermocouple thermoelectric power generated by the corresponding temperature value. Platinum and rhodium thermocouple measuring thermal electromotive force will end with the growth temperature increases, its size only to the ends of the thermocouple and temperature-related material, and the length of the hot electrode diameter has nothing. A variety of platinum and rhodium thermocouple shape often due to very different needs, but their basic structure is substantially the same as a main component is usually hot electrode, an insulating sleeve protective tube and junction boxes and other components. Application of platinum and rhodium thermocouple manufacturing process for a variety of high temperature applications, widely used in powder metallurgy, sintering furnace bright, vacuum furnace, smelting furnace, glass, ceramics and steel-making furnaces and industrial salt bath furnace temperature.
