摘要

温度测量中使用不同类型的温度计（电阻温度计、热电偶、玻璃中液体温度计、辐射温度计等）。电阻温度计是用于敏感温度测量的最可靠的传感器类型之一。测量结果的可追溯性、准确性和精密度对测量的可靠性至关重要。在电阻温度计的测量中，有许多参数会影响不确定度的估计。不确定性估计中要考虑的参数之一是将电阻值转换为温度时的插值误差。可以使用不同的方法（ITS-90、Calendar Van Dusen CVD、多项式方程）将电阻值转换为温度。问题在于，使用通过不同方法获得的系数读取的温度值存在差异。在本研究中，研究了CVD和多项式方程方法的误差对测量不确定度的影响。

The Effect of the Conversion Coefficients of Platinum-Based Resistance Thermometers on the Uncertainty Estimation

Different types of thermometers (resistance thermometers, thermocouples, liquid in glass thermometers, radiation thermometers, etc.) are used in temperature measurements. Resistance thermometers are among the most reliable types of sensors used for sensitive temperature measurements. The traceability, accuracy and precision of the measurement results are important for the reliability of the measurements. There are many parameters that affect the uncertainty estimation in measurements made with resistance thermometers. One of the parameters to be considered in the uncertainty estimation is the interpolation error in converting the resistance value to temperature. Different methods (ITS-90, Calendar Van Dusen CVD, Polynomial equation) can be used to convert the resistance value to temperature. The problem is that there are differences in the temperature values read using the coefficients obtained by different methods. In this study, the effect of errors from CVD and polynomial equation methods on measurement uncertainty was investigated.
