W re thermocouple is a kind of high temperature resistant thermocouple. It has the advantages of good temperature potential linear relationship, reliable thermal stability and low price. Matching with display instrument, it can directly measure the temperature of liquid, steam and gas medium. It can partly replace platinum rhodium thermocouple as high-tech metallurgical industry, high-temperature electronic thermoelectric system structure engineering and space vehicle, nuclear reactor ultra-high temperature measurement tool.

The relationship between thermoelectric potential and temperature of W re thermocouple conforms to zbn05003-88 graduation table, which is equivalent to ASTM e696-84 standard. It can be used in the range of 0 ~ 2300 ° C in vacuum, reduction and inert gas. Tungsten rhenium thermocouple with special protection tube can also be used in oxidation gas at 1600 ° C for a long time, and its price is lower than that of platinum rhodium thermocouple.
