As one of the important elements in the dynamic balancing measurement system, transducer is the device that converts the vibration signal caused by the imbalance into electrical signal without distortion. The piezoelectric pressure transducer is applied to dynamic balancing measurement system for measuring the vibration caused by imbalanced mass. The structure design and the installation location of the piezoelectric force transducer and the critical issues in vibration signal detection are expounded. The characteristics of the signal conditioning circuit of this transducer are analyzed in detail. The experimental results show that the performance of the piezoelectric pressure transducer offers excellent performance in dynamic balancing measurement.
