2. The use of tungsten rhenium thermocouples. At present, non-contact methods are commonly used to measure temperatures above 1600 ℃. However, this method has a large error, and using the contact method can accurately measure the true temperature. In high-temperature thermocouples, precious metal thermocouples are expensive and the highest temperature can only be below 1800 ℃, while tungsten rhenium thermocouples not only have a high temperature limit but also good stability. Therefore, tungsten rhenium thermocouples are widely used in metallurgy, building materials, aerospace, aviation, and nuclear energy industries. China has abundant tungsten resources, and tungsten rhenium thermocouples are cheap and can partially replace precious metal thermocouples. They are a promising temperature measurement material in the field of high-temperature testing.

3. Use temperature. Its maximum operating temperature can reach 2800 ℃, but data dispersion occurs above 2300 ℃. Therefore, the optimal temperature for use is around 2000 ℃.

4. Use environmental atmosphere. Tungsten rhenium thermoelectric dipoles are prone to oxidation and are suitable for use in inert or dry hydrogen gas, or with dense protective tubes to isolate them from oxygen before use. Cannot be used in a carbon containing atmosphere (such as in an atmosphere containing hydrocarbons, where corrosion occurs at temperatures exceeding 1000 ℃). Tungsten or tungsten rhenium is prone to generate stable carbides in a carbon containing atmosphere, which can reduce its sensitivity and cause brittle fracture. In the presence of hydrogen gas, it can accelerate carbonization.

5. Tungsten rhenium thermocouple is resistant to oxidation. This issue has always been a topic of concern for scholars both domestically and internationally, and they are committed to researching and solving it. Our company has adopted excellent manufacturing technology and successfully developed a prefabricated high-temperature and high-pressure W-Re thermocouple. The temperature measurement range of this product is 0-1800 ℃, which is widely used in metallurgy, coking, chemical kilns, heat treatment, glass and other industries. It has the advantages of high accuracy, low price, stable performance, and is not limited by the working environment and atmosphere. It is an ideal product to replace platinum rhodium thermocouples. The W-Re thermocouple produced by our company has been widely used in units such as Zhuzhou Hard Alloy Factory, Zigong Hard Alloy Factory, and Shenyang Zhongke Instrument, and its performance has reached the level of similar foreign products.
