A Research for Error Compensation Algorithm of Dual Range Pressure Sensor

Abstract

Abstract:Large range-high precision measurement has always been a challenge in the field of mechanical measurements. This paper built the input-output differential equation of Dual Range Pressure Sensor (DRPS) and gave an error compensation algorithm of DRPS after analyzing the mathematical model of DRPS. For a given situation, dynamic measurement errors of sensor parameters can be compensated by this method. Finally the accuracy and feasibility of the method were verified using Adams Software.
