STUDY ON THERMAL DRIFT OF NOBLE METAL THERMOCOUPLES

• Abstract:

  We set up the temperature - running period CM (Characteristic Modelling) of the noble metal thermocouples (S/B type). Using CM, we got the both thermocouples max error reduced, type S is 2.1 °C and type B is 1.8 °C which were 5.8 °C and 4.3 °C before using CM and the coefficients of determination in CM are 82.1 % and 72.5 %. It shows 85 % difference between CM and error less than 1.0 °C, especially in type B. So it is necessary to use CM to measure temperature accurately.
