Background. Products from piezomaterials are widely used as primary measuring converters for monitoring the parameters of industrial equipment in various fields of technology. Working in harsh operating conditions, products from piezomaterials should preserve their parametric characteristics as much as possible. This necessitates the development of measuring system for monitoring and analyzing the parameters of pie-zomaterials.
Materials and methods. The article describes the structure of the hardware of the automated meter piezomaterials parameters. Results. The simulation of the measuring circuit was made, the AFC curves were obtained and the electrical parameters for the model of the piezoceramic element were determined.
Conclusions. Automated measuring instru-ment of piezomaterial products allows to determine the resonance frequencies, quality fac-tor and electrical parameters of piezoceramic elements in accordance with the four-element equivalent electrical circuit.
