“…Pressure thermometers are mainly based on the relationship between water vapor pressure and temperature changes within the temperature measurement system to achieve temperature measurement [1]. However, due to the influence of the temperature measurement environment and temperature measurement methods, the measurement results of pressure thermometers often exhibit certain errors [2]. Therefore, it is necessary to detect the temperature measurement error of the pressure thermometer.…”

The current conventional pressure thermometer temperature measurement error detection method mainly realizes detection by calculating the fixed error of temperature measurement, which leads to poor detection effect due to the lack of analysis of the uncertainty in the temperature measurement process. Therefore, based on Hall sensors, research has been conducted on the detection method of temperature measurement errors in pressure thermometers. Firstly, the uncertainties in different temperature measurement scenarios are analyzed and combined, and the temperature measurement error detection device is constructed. Hall sensors are used to judge the stability of the thermometer temperature values in the thermostat tank, and the actual temperature error is calculated by combining the deviation values brought by the uncertainties. In the experiment, the proposed method is tested for the accuracy of temperature measurement error detection. The experimental results show that the proposed method has a low misjudgment rate and has a more excellent detection effect when the temperature measurement error of the pressure thermometer is detected by the proposed method.
