According to general piezoelectric acceleration sensor measurement circuit existing problems in the dynamic testing field, the paper proposes the modular, integration design method, using the integrated chips CA3140 to design the signal disposal circuit, in order to reduce the cost and improve the circuit SNR, enhance the stability and reliability of the circuit. This circuit includes a charge amplifier, conditional amplifier, low-pass filter, high-pass filter and output amplifier. The test shows that the circuit functions are complete, it is practical and reliable. It has a higher performance price ratio, and can be widely used in the dynamic monitoring and the diagnosis of fault or defect about the equipment and structure.
