The piezoelectric sensor is the best choice for large industrial installations for instantaneous monitoring and premature fault diagnosis of electromechanical systems. In this work, we made a study on the piezoelectric detection and the piezoelectric sensor then a model of the physical behavior of this sensor extracted. The developed model of measurement accuracy as a function of the relative vibration movement is validated by experimental tests and simulation. The good choice of the damping rate allowed to improve the parameters of the sensor on the one hand and to advance the technique of vibratory analysis on the other hand.
