Use of console piezoceramic identifiers in vibrodiagnostics аt the definition of emergency situations of potentially hazardous productions

The article discusses the possibility of identifying technological equipment that can be used in the system for determining emergency situations of potentially hazardous industries. For this purpose, it is offered to use console piezoelectric transducers based on asymmetric bimorph piezoelectric elements. By changing the size and shape of the electrodes on opposite sides of a thin piezoelectric element, a change in the characteristics of piezoelectric transducer is achieved, which serves as an identifier for the transducer, and hence for the equipment on which it is attached. Moreover, the areas of the electrodes on opposite sides do not intersect, which provides the conditions for the occurrence of domain-dissipative properties of piezoelectric element
