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 30% rhodium, platinum 70%, negative (BN) as a platinum-rhodium alloy, containing rhodium 6%, so-called double platinum and rhodium thermocouple. The long-term maximum temperature of thermocouple 1600 ℃, S-type thermocouples, 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, S-type thermocouple principle, 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 thermoelectric power, thermoelectric power is small, low sensitivity, reduction in mechanical strength at high temperatures, very sensitive to pollution, how much S type thermocouple, precious metal expensive, so a one-time investment is large. Platinum and rhodium 10 - platinum thermocouple (S-type platinum-rhodium thermocouple) is a noble metal thermocouples. Thermocouple wire diameter is defined as 0.5mm, tolerance -0.015mm, its positive (SP) in the name of the chemical composition of platinum and rhodium alloy, which contains 10% rhodium, platinum was 90%, and negative (SN) of pure platinum, so Commonly known as single platinum-rhodium thermocouple. Platinum and rhodium thermocouple long-term maximum use temperature of 1300 ℃, short-term maximum temperature of 1600 ℃. S-type thermocouple has the highest accuracy thermocouple series, best stability, temperature of wide-temperature, long life and other advantages. It's physical, good chemical resistance, thermoelectric power at high temperature stability and good oxidation resistance, suitable for oxidizing and inert atmosphere. Since the S-type platinum-rhodium thermocouple has an excellent overall performance, Anhui S-type thermocouples, in line with international use S-type thermocouple temperature scale, has long served as an international temperature scale inserted instrument, "ITS-90" although no longer provides for the future As an international temperature scale investigation instrument, but the international temperature Advisory Committee (CCT) that the S-type thermocouple can still be used to approximate the realization of the International Temperature Scale.
