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 ℃, Anhui sheathed thermocouple, short-term maximum temperature of 1600 ℃. S-type thermocouple has the highest accuracy in thermocouple series, sheathed thermocouple, 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 excellent overall performance, in line with the international temperature scale using S-type thermocouple, WRNK-101 armored thermocouple, has long served as an international temperature scale inserted instrument, "ITS-90", although provisions in the future As the temperature is no longer the subject of an international search 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. Principle structure sheathed thermocouple is a handheld sheathed thermocouple, is a conductor, high magnesium oxide insulation, jackets 1Cr18Ni9Ti stainless steel protection tube, after numerous one drawn from. Thermocouple products are mainly from junction boxes, terminals and components of the basic structure sheathed thermocouple, and with a variety of mounting device. Sheathed thermocouple thermal response time when a step change in temperature occurs, the thermocouple output changes to income equivalent to 50% of the time that a step change is called the thermal response time, with τ0.5 representation.
