Tungsten rhenium thermocouples classification. Included in the national standards of tungsten rhenium thermocouple has two: A, tungsten rhenium tungsten-rhenium 5- 26, its positive nominal composition containing tungsten 95% rhenium 5%, negative nominal composition containing tungsten 74% rhenium 26 ??? Indexing number WRe5-WRe26, abbreviated: W-Re5 / 26. B, tungsten, rhenium tungsten rhenium 3- 25, its positive nominal composition 97% tungsten, 3% rhenium, tungsten negative nominal composition of 75%, 25% rhenium. Indexing number WRe3-WRe25, K-type thermocouple prices, abbreviated: W-Re3 / 25. The use of tungsten-rhenium thermocouples. Currently measuring a temperature above 1600 ℃, the use of non-contact method, however, the error of the ways larger, K-type thermocouple, such as a contact rule can accurately measure the real temperature. In the high temperature thermocouples, precious metal thermocouples are expensive and can only be a maximum temperature below 1800 ℃, K-type thermocouple companies, and tungsten-rhenium thermocouple temperature upper limit is not only high, but also good stability, therefore, tungsten-rhenium thermocouples in metallurgy, building materials, aerospace, aviation and nuclear industries have been widely used. China has abundant resources of tungsten, tungsten-rhenium thermocouples cheap prices, precious metal thermocouples can be partially substituted, it is in the field of high-temperature test promising temperature materials.
