Abstract In view of the lack of relevant research on the influence of temperature on the field calibration of air pressure sensors,the air pressure sensors are calibrated in the laboratory environment with stable temperature and in the field environment (during temperature rising periods).By comparing the calibration results,it can be concluded that in the field calibration,with the increase of temperature,the deviation value of the measurement error of each calibration point gradually increases,and the fluctuation of the error also gradually increases.Therefore,it is necessary to carry out field calibration when the ambient temperature is stable,so as to better improve the reliability of calibration results.
