标准及工业用铂铑_(10)—铂热电偶检定规程中规定,该热电偶的热电势值在300~1300℃范围内,在锌、锑、铜三个固定点分离后用下式进行计算: E_1=E_1F_1(t)+E_2F_2(t)+E_3F_3(t)而国标GB3772—83给出的铂铑_(10)—铂热电偶分度表与IEC出版物584—1中分度表值相同,该分度表中给出了-50°~1769℃范围内温度与对应热电势值。分度表按以下四个温度范围采用不同计算公式计算得出的。
Standard and industrial use of platinum and rhodium _ (10) - platinum thermocouple test procedures stipulate that the thermocouple thermoelectric power value in the range of 300 ~ 1300 ℃, zinc, antimony, copper after the separation of the three fixed points with the following formula Calculation: E_1 = E_1F_1 (t) + E_2F_2 (t) + E_3F_3 (t) And the national standard GB3772-83 platinum rhodium _ (10) - platinum thermocouple index table and IEC Publication 584-1 indexing table The same value, the index table gives -50 ° ~ 1769 ℃ temperature and the corresponding thermoelectric potential value. Index table according to the following four temperature ranges calculated using different formulas.
