In-situ Calibration of Differential Pressure Sensor Based on Least Square Method
摘要
Abstract
Considering the swing moment calculation inaccuracy due to the complex data processing of differential pressure sensor in nozzle swing test,the in-situ calibration technique of differential pressure sensor is studied.The least square method is used for the processing of calibration data,the processing formula of sensor output data is modified,and the accuracy of nozzle swing torque is improved.The paper describes the method of in-situ calibration of a differential pressure sensor as well as the application of least square method in calibration.As compared with the previous calculated result,the calculation accuracy of the differential pressure sensor output data after calibration is improved by 56.88%.关键词
