Rhenium tungsten thermocouple is high temperature resistant thermocouple. It has the advantages of good linear relation between temperature and potential, reliable thermal stability and low price. It can measure the temperature of liquid, steam and gas media directly. It can partially replace platinum rhodium thermocouple as a high and new metallurgical industry, high temperature electronic thermoelectric system structure engineering and space vehicle for nuclear reactors. The relationship between rhenium tungsten thermocouple thermoelectric potential and temperature conforms to zbn05003-88 scale, which is equivalent to astme 696-84 standard. In a vacuum, reduction, inert atmosphere, can be used within 0 ~ 2300 ℃. The use of special protection tube of tungsten-rhenium accidentally can also in the oxidation atmosphere of the long-term use under 1600 ℃, its price lower than platinum rhodium thermocouple.

Use the environment. Rhenium tungsten-tungsten thermocouple is easy to oxidize and is suitable for use in inert or dry hydrogen gas, or for use only when it is isolated from oxygen with dense protective tubes. Cannot be used for carbon atmosphere, such as used in the atmosphere containing hydrocarbons, a temperature over 1000 ℃ or corrosion). Tungsten or tungsten-rhenium tends to produce stable carbide in a carbon-containing atmosphere, which reduces its sensitivity and leads to brittle fracture. In the presence of hydrogen gas, it will accelerate carbonization.
