Influence of Extreme Temperature on Characteristics of Electric Equivalent of Piezoceramic Transducer

The paper is dedicated to the issue of temperature variation influence on the characteristics of piezoceramic transducer to verify its possible use in extreme temperature conditions in specific applications e. g. military, aerospace, etc. The paper presents equivalent schematics of piezoceramic transducers - both transmitter and receiver. Next, there are presented dependences of impedance magnitude and angle on frequency of specific transmitter or receiver and their analysis is performed. In the last section of the article, the real responses of the whole system, transmitter - environment - receiver, on an input signal for relevant temperatures are presented together with their analysis.
