Tungsten Rhenium Thermocouple
Description
Tungsten rhenium thermocouple, also known as tungsten-rhenium thermocouple, has good chemical stability, large electromotive force, and high sensitivity in a non-oxidizing atmosphere. It can be directly used to measure, with display instrument, the temperature of liquid, steam and gas media. The using temperature range is 1300 ~ 1700℃.
The thermal electromotive force of tungsten rhenium thermocouple depending on the temperature conforms to the ZBN05003-88 indexing table, which is equivalent to the ASTME696-84 standard. It will be suitable for using in vacuum, reducing and inert atmosphere. When wrapped with special protective tube, the tungsten rhenium thermocouple can even be utilized for a long time in the oxidizing atmosphere of 1600℃. And relative to platinum-rhodium thermocouple, it has a lower price.
Application
Integrated with a display instrument, the tungste rhenium thermocouple can be directly used to measure the temperature of liquid, steam and gas media, etc.
It can partially be used instead of platinum and rhodium thermocouple as ultra-high temperature measurement tools which are used in high-tech metallurgical industry, high-temperature electronic thermoelectric system structure engineering and space delivery vehicles, and nuclear reactors.
