Abstract: Analyses of the properties of conical piezoelectric acoustic emission transducer are presented here. The conical piezoelectric transducer is used to scanning normal displacement on a surface of testing constructions in NDT methods, such as acoustic emission. The simplified one-dimensional analysis based on the equivalent circuit of conical waveguide is recapitulated. FEM analysis on this transducer is presented. Both the frequency response characteristic of the transducer and his time response on pulse excitation are results of this analysis. All of computations are done for various cone angles of piezoceramic (PTZ-H5) element and various sizes of the cylindrical backing of the sensor.
