In previous work, we developed a calibration apparatus for use with contact surface thermometers. In this apparatus, the temperature of the upper surface of a copper cube was used as reference surface temperature. In this new study, uncertainty components due to environmental conditions in the measurement space were estimated by measuring the temperature of the upper surface of the calibration apparatus and the output of contact surface thermometers while varying ambient temperature and air flow speed. It was found that the temperature of the upper surface of the calibration apparatus and the output of the contact surface thermometer increased with increasing ambient temperature. The uncertainty in our previous work due to the effect of the ambient temperature was estimated to be 0.01 °C, based on the ±1 °C variance of the ambient temperature in the lab room. We also found that the measured values tended to decrease with increasing the air flow speed around the calibration appar...

使用校准设备估算环境对接触表面温度计性能的影响

在以前的工作中，我们开发了一种用于接触式表面温度计的校准设备。在该装置中，将铜立方体的上表面的温度用作基准表面温度。在这项新研究中，通过测量校准设备上表面的温度和接触表面温度计的输出，同时改变环境温度和空气流速，来估算由于测量空间中的环境条件引起的不确定性分量。已经发现，校准设备的上表面的温度和接触表面温度计的输出随着环境温度的升高而增加。由于环境温度的影响，我们先前工作中的不确定性估计为0.01°C，根据实验室室内环境温度的±1°C方差确定。我们还发现，随着校准设备周围空气流速的增加，测量值趋于降低。
