WRe5 / 26 tungsten-rhenium thermocouples antioxidant vacuum tungsten rhenium thermocouples

Tungsten-rhenium thermocouples are temperature thermocouple, which has a good potential temperature linear relationship, reliable thermal stability, and low price. And display instrument can directly measure temperature of liquid, vapor and gases and the like. It can be a partial substitute for platinum and rhodium thermocouple metallurgical industry as high-tech, high-temperature electronic thermoelectric system architecture engineering and space vehicles, ultra-high temperature nuclear reactor measurement tools. Tungsten-rhenium thermocouple temperature thermoelectric power relationship in line with ZBN05003-88 indexing table, equivalent ASTME696-84 standards. In the vacuum, reducing, inert atmosphere, it can be used in a range of 0 ~ 2300 ℃. Special protective tube tungsten-rhenium even long-term use can also be an oxidizing atmosphere at 1600 ℃, the price lower than the platinum-rhodium thermocouple. Temperature insulation resistance of tungsten-rhenium thermocouples in the ambient air temperature of 20 persons 15 ℃, relative humidity less than 85% of the heat insulation resistance between the electrode and the outer protective tube should be greater than 100MΩ.m tungsten-rhenium thermocouples outer protective tube selection (l) silicon carbide tube (Sic) can be used (2) molybdenum disilicide tube (Mosi2) air and some corrosive atmosphere below 1600 ℃ in use (supply agreement) (3) molybdenum tube in 1600 ℃ under an oxidizing atmosphere ( Mo) using the following vacuum at 2300 C (supply agreement) (4) Tantalum tube (Ta) use (supply agreement) tungsten-rhenium thermocouples Main Specifications Product Name Model No. indexing indexing ASTM vacuum at 2300C or less No. temperature range ℃ tolerance using tungsten-rhenium thermocouples antioxidant atmosphere WRW-1500 type WRe3 / 25 D 0 ~ 1650 ± 0.5% |t| oxidation, vacuum, inert gas such as reducing WRe5 / 26 C 0 ~ 1650 ± 0.5% |t| tungsten-rhenium thermocouples Product type structure protection tube diameter (mm) outside the inner protection tube material inside and outside the WRW-1500 type double tube 166 exceptionally pure alumina tube pipe three tube molybdenum silicide 25,166 extra virgin alumina tube molybdenum silicide extra virgin alumina tube pipe three tube 30166 recrystallized silicon carbide tube exceptionally pure alumina tube molybdenum silicide management company name; Hayward blue Instrument Co., Ltd.
