铠装热电偶两种校准方法的比较

摘要

通过JJG 351-1996与JJF 1262-2010两种方法对8支铠装K型热电偶进行测试，分析得出后者方法的复现性更佳，不确定度更小，更符合铠装廉金属热电偶的固有特性。%In this article, we calibrate 8 K type Sheathed thermocouples according to JJG 351-1996“Verification Regulation of Working Base Metal Thermocouple”and JJF 1262-2010“Calibration Spectification for Sheathed Thermocouples”. The research results indicate that the latter method gets better Reproducibility and smaller Uncertainty. So the latter method is better for the calibration of sheathed thermocouple.
