Platinum rhodium thermocouple is also called high temperature metal thermocouple

Platinum rhodium thermocouple is also called high temperature thermocouple, precious metals platinum rhodium have single platinum rhodium ( Platinum rhodium - 10 Platinum rhodium) And double platinum rhodium ( Platinum rhodium - 30 Platinum rhodium (6) And thermocouple as the temperature measurement sensor, usually with temperature transmitter, controller and display instrument, such as process control system, to directly measure or control in the production of a variety of 0 Fluid over a range of 1800 ℃, steam and gas medium and solid surface temperature. Platinum rhodium thermocouple for precious metals thermocouple. Accidentally wire diameter provision of 0. 5 mm, allowable deviation - 0. The positive (015 mm, 英国石油公司(BP) In the name of the chemical composition of platinum rhodium, contain the rhodium is 30%, platinum-based is 70%, the cathode ( BN） For platinum rhodium, rhodium for content 6%, therefore, commonly known as the dual platinum-rhodium thermocouple. The thermocouple * long-term high temperature of 1600 ℃, short-term * high temperature of 1800 ℃. Take a look at the advantages and disadvantages of them: advantages: platinum rhodium thermocouple in thermocouple series, with the high accuracy * and * good stability, test your area wide, long service life, high upper limit of thermocouple temperature measurement, etc. Suitable for oxidation and inert atmosphere, can also be short term used in vacuum, but does not apply to reducing atmosphere or containing metal or nonmetal steam atmosphere. B type thermocouple is an obvious advantage don't need a compensation for the compensation conductor, because in the range of 0 ~ 50 ℃ and internal potential less than 3 mu V.
