1：Overview
WR series industrial precious metals platinum and rhodium thermocouple called thermocouples, temperature measurement sensors as, often with temperature transmitters, regulators, and display instruments, such as supporting the use of the composition process control system for the direct measurement or control 0-1800 ℃ kinds of production process within the fluid, vapor and gases and solid surface temperature。
Platinum rhodium thermocouple is composed of two different components of the conductor connected at both ends of circuit synthesis, when the two not the same junction temperature, heat will be generated within the loop current. If the working end of the thermocouple and reference junction temperature difference exists, the display meter will be instructions on the thermocouple thermoelectric power generated by the corresponding temperature value。
Platinum rhodium thermocouple measurement of heat electric heat will end with the growth temperature increases, its size is only material and ends with the thermocouple temperature, and the hot electrode length and diameter has nothing to do。
The shape of a variety of platinum and rhodium thermocouple often very different because of the needs, but they are roughly the same basic structure, usually by the hot electrode, insulation protection tube and junction box sets and other major ingredients。

2：Application
Platinum rhodium thermocouple for high temperature production process in various occasions, is widely used in powder metallurgy, sintering bright furnace, vacuum furnace, smelting furnace, glass, ceramics and steel-making furnaces and other industrial salt bath temperature。
