Research on the Compliance Judgment of Indication Error of Calibration Result of Platinum Resistance Air Temperature Sensor

In view of the current situation that the conformity of measurement results was not judged when tracing the source of air temperature sensor in automatic weather station in the past. In this paper, the representative platinum resistance air temperature sensor is selected. Through the design and implementation of the calibration experimental scheme, the indication error of the corresponding calibration point is obtained, and the measurement uncertainty u95 is analyzed and evaluated. Finally, the conformity of the indication error of the calibration results is determined based on u95. The results are: it is qualified at −10 °C and 0 °C, It is determined to be undetermined at 20 °C and 50 °C. There is a deviation from the result without indication error conformity judgment, Therefore, it is necessary to judge the compliance of the indication error of the calibration result of the platinum resistance air temperature sensor.
