| Abstract: | By establishing the model,this paper analyzes the uncertainty sources of measurement results for PTB330 pressure sensor,and the uncertainty components of measurement results are evaluated.The combined standard uncertainty and extended uncertainty of indication error measurement are obtained.The ten pressure sensors were selected to evaluate the uncertainty of measurement results at each detection point according to the requirements of the verification regulations of pressure sensors for automatic weather station,so as to provide scientific reference for the verification results of the same type of pressure sensors. |
