High-temperature tungsten-rhenium thermocouples are temperature thermocouples. It has a good electrical 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 relations in line with ZBN05003-88 indexing table, reflow Thermocouple equivalent ASTME696-84 standards. In the vacuum, reducing, inert atmosphere, sheathed thermocouples 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. Platinum and rhodium 30 - 6 platinum and rhodium thermocouple (B-type platinum-rhodium thermocouple) is a noble metal thermocouples. Thermocouple wire diameter is defined as 0.5mm, tolerance -0.015mm, its positive (BP) in the name of the chemical composition of platinum and rhodium alloy, which contains rhodium 30%, WRN threaded sleeve sheathed thermocouple, platinum is 70% negative (BN) of platinum and rhodium alloy containing rhodium 6%, so-called double platinum and rhodium thermocouple. The long-term maximum temperature of thermocouple 1600 ℃, short-term maximum temperature of 1800 ℃. B-type thermocouple thermocouple series in the most accurate, best stability, temperature of wide-temperature, long life, temperature upper limit advantages. Suitable for oxidizing and inert atmosphere, can also be used in a vacuum in the short term, but not for reducing atmosphere or containing metal or non-metal vapor atmosphere. B-type thermocouple an obvious advantage is no need to compensate with compensation wire, because in the range of 0 ~ 50 ℃ thermal EMF of less than 3μV. B-type thermocouple deficiency is that the thermoelectric power, flat plug-type thermocouples, thermoelectric power is small, low sensitivity, reduction in mechanical strength at high temperatures, very sensitive to pollution, precious metal expensive, so a larger one-time investment .
