Tungsten Rhenium Thermocouple Wire

Product Introduction


The Tungsten rhenium thermocouple is a high temperature resistant thermocouple. It features an outstanding temperature-potential relationship, high thermal stability, and low price. Matched with appropriate display instruments, it can directly measure the temperature of liquids, steam and gas media. Can be used between 0 and 2,300°C in vacuum, reducing, and inert atmospheres.

Tungsten-rhenium 5-tungsten-rhenium 26: nominal composition of the positive electrode is 95% tungsten and 5% rhenium, while the nominal composition of the negative electrode is 74% tungsten and 26% rhenium. Graduation number WRe5-WRe26, abbreviated to W-Re5/26 (ASTM graduation number: C).

Tungsten-rhenium 3-tungsten-rhenium 25: Nominal composition of the positive electrode is 97% tungsten and 3% rhenium, while the nominal composition of the negative electrode is 75% tungsten and 25% rhenium. Graduation number WRe3-WRe25, abbreviated to W-Re3/25 (ASTM graduation number: D).

 

 

 

Product Application


Tungsten-rhenium thermocouples can partially replace platinum-rhodium thermocouples as ultra-high temperature measurement tools for high-tech metallurgical industries, high-temperature electronic thermoelectric structural engineering and space vehicles, as well as nuclear reactors.
