Abstract: We discuss the problems of obtaining the transfer function of the resonant piezoelectric sensors based on the use of piezoceramic transformers (PCT), operating at the resonant frequency. In general, the dynamics of the PCT are described by nonlinear equations having the amplitude-time-space character. Therefore, the analysis of dynamic processes in PBC due to the influence of the environment, multiple connection, nonlinearity and its distribution parameters presents considerable mathematical difficulties. It is shown that for practical purposes the transfer function can be sufficiently accurate estimated by experimental and experimental-analytical methods.
Keywords: piezoelectric transducer, piezoceramic transformer, dynamic properties, the transfer function
