What is Tungsten-rhenium thermocouple?

Tungsten-rhenium thermocouple is the most successful refractory metal thermocouple, and also can be measured to 1800℃ above the industrial thermocouple performance of the best thermocouple.With the development of high technology, the application of tungsten-rhenium thermocouple will be more and more extensive.

Tungsten-rhenium thermocouple features: high melting point of hot electrode wire (3300℃), large strength.The thermoelectric electromotive force is large, high sensitivity, the rate of common thermoelectric electromotive force is two times of S type thermocouple and three times of B type thermocouple.It oxidizes very easily

Tungsten-rhenium thermocouple: the ideal temperature range of tungsten-rhenium thermocouple is 0-2300℃, the best temperature is 1300-2000℃.Its structure is single or double tube, the protection tube is fine and extra pure corundum, pure molybdenum tube, cermet, tantalum tube, tungsten tube, etc., after vacuuming, it is filled with extra high temperature insulation material, durable, widely used in vacuum, hydrogen, nitrogen and other reducing atmosphere and inert gas protection furnace.
