In modern industry and automatic production, the accurate measurement of the vibration and strike in testing dynamically seems especially important. For the acquisition of signal, the most common used sensor is piezoelectric accelerometer. On the basis of researching piezoelectric accelerometer sensor, this paper analyzed the work principle of measurement,proposed a kind of accelerometer measurement design method. Adding temperature sensor to compensate temperature, the applied temperature rang could be wider. Detection circuit suiting this kind of sensor and the system composition of accelerometer measurement was also given in the paper. This design method was accurate with high value for application and extension. Also the structure was simple, the price was lower and, the performance was stable.
