Commonly used thermocouples can be divided into two categories: standard thermocouples and non-standard thermocouples. The standard thermocouple referred to refers to the thermocouple whose thermoelectric potential and temperature are stipulated in the national standard, allow errors, and have a consistent standard indexing table. It has a matching display surface for selection. Non-standardized thermocouples are not as good as standardized thermocouples in terms of application range or order of magnitude, and generally do not have a consistent indexing table, which is mainly used for measurement in some special occasions. Seven standardized thermocouples of S, B, E, K, R, J, and T are uniformly designed thermocouples in my country. There are mainly S, R, B, N, K, E, J, T, etc. for the graduation numbers of thermocouples. Among them, S, R, B belong to precious metal thermocouples, and N, K, E, J, T belong to cheap metal thermocouples. The following is the explanation of the thermocouple graduation number S platinum rhodium 10 pure platinum R platinum rhodium 13 pure platinum B platinum rhodium 30 platinum rhodium 6 K nickel chromium nickel silicon T pure copper copper nickel J iron copper nickel N nickel chromium silicon nickel silicon E Nickel-chromium-copper-nickel (S-type thermocouple) platinum-rhodium 10-platinum thermocouple platinum-rhodium 10-platinum thermocouple (S-type thermocouple) is a precious metal thermocouple. The diameter of the even wire is specified as 0.5mm, and the allowable error is -0.015mm. The nominal chemical composition of the positive electrode (SP) is platinum-rhodium alloy, which contains 10% rhodium, 90% platinum, and the negative electrode (SN) is pure platinum, so Commonly known as single platinum rhodium thermocouple. The maximum operating temperature of the thermocouple is 1300°C for a long time and 1600°C for a short term.
