tungsten rhenium thermocouple manufacturers tell you about the most successful refractory metal thermocouples developed in the 60s and 70s. The characteristics of the tungsten-rhenium thermocouple are: the hot electrode wire has a high melting point (3300 ° C), a low vapor pressure, and is easily oxidized; it has good chemical stability in a non-oxidizing atmosphere. The electromotive force is large, the sensitivity is high, and the most important thing is the low price.

The tungsten rhenium thermocouple is a high temperature thermocouple. It has the advantages of good temperature-potential linear relationship, reliable thermal stability and low price. Matched with the display instrument, it can directly measure the temperature of liquid, steam and gas medium.
tungsten rhenium thermocouple can partially replace platinum-rhodium thermocouple as a high-tech metallurgical industry, high-temperature electronic thermoelectric system structural engineering and space vehicles, and ultra-high temperature measurement tools for nuclear reactors.
The relationship between thermoelectric potential and temperature of tungsten rhenium thermocouple conforms to the ZBN05003-88 graduation table, which is equivalent to the ASTME696-84 standard. In vacuum, reducing and inert atmosphere, it can be used in the range of 0~2300℃. Tungsten-rhenium couples with special protection tubes can also be used for a long time in an oxidizing atmosphere at 1600 °C, and their price is lower than that of platinum-rhodium thermocouples.
