The thermocouple type

Thermocouple index number of commonly used thermocouple could be divided into two types: standard thermocouple and non-standard thermocouple. Invokes standard thermocouple is refers to the national standard specifies its thermoelectric potential and the relationship between temperature, permissible error, and a unified standard score table of thermocouple, it has with matching display instrument to choose from. Non-standard thermocouple or on the order of magnitude less than the range using standardized thermocouple, generally no unified indexing table, mainly used for the measurement of some special occasions.

standardized thermocouple since January 1, 1988 in our country, the thermocouple and thermal resistance were manufactured according to IEC international standard, and specify the S type thermocouple, B type thermocouple, E type thermocouple, K type thermocouple, R type thermocouple, J type thermocouple, T seven standardized thermocouple type thermocouple for our country unified design. Thermocouple index number mainly S, R, B, N, K, E, J, T wait for a few kinds. S, R, B belong to precious metal thermocouple, N, K, E, J, T belong to cheap metal thermocouple. The following is the interpretation of the thermocouple indexing number S 10 pure platinum rhodium platinum R platinum rhodium 13 pure platinum
