From the working characteristics,scope of application and some main factors that affect the working performance of piezoelectric sensors,and based on the two kinds of the measuring circuits that are put forward in this paper,the performance of measuring circuits is further analyzed. In order to improve the working performance of piezoelectric sensors,differential amplification forms of signal conditioning circuit are designed to reduce interference and drift. And through EWB simulation software the design of the signal adjustment circuit is simulated. The results show that the differential amplification form of the signal adjustment circuit achieves the desired optimization requirement.
