S type thermocouple simple introduction

S type thermocouple introduces 10 - platinum rhodium Platinum thermocouple ( S type thermocouple) For precious metals thermocouple. Accidentally wire diameter provision of 0. 5 mm, allowable deviation - 0. The positive (015 mm, SP） In the name of the chemical composition of platinum rhodium, contain the rhodium is 10%, platinum-based is 90%, the cathode ( SN) For pure platinum, commonly known as single platinum-rhodium thermocouple. The thermocouple * long-term high temperature of 1300 ℃, short-term * high temperature of 1600 ℃. S type thermocouple in the series of thermocouple with high accuracy *, * good stability, test your area wide, long service life, etc. Its physical and chemical performance is good, the thermoelectric potential stability and oxidation resistance at high temperature performance is good, suitable for oxidizing and inert atmosphere. Because of S type thermocouple has excellent comprehensive performance, in line with the international use of S type thermocouple temperature scale, has for a long time as an international scale interpolation instruments, 'ITS - Although 90 'provisions will not be as an international scale in check instruments, but the international advisory committee (temperature 有条件现金转移支付) S type thermocouple can still be used for approximate to realize international temperature scale. S type thermocouple under normal use for a long time when the temperature is 800 ~ 1300 ℃ or so * high measurement precision, and in 800 ℃ temperature measurement accuracy is not high, but the long-term use of temperature above 1300 ℃ can easily damage the thermocouple, so select the correct index number of thermocouple temperature measurement accuracy is the important factor.
