FIELD: measuring equipment.
SUBSTANCE: essence of the method for determining electrical parameters of a piezoelectric transducer is that excitation of converter is carried out by means of electric noise signal, arising as a result of intrinsic thermal oscillations of the polarized piezoelectric material of the piezoelectric element of the transducer, recording the electrical signal obtained at the output of the converter in the operating frequency range of the transducer, determining transducer parameters using values of characteristic frequencies of extrema, corresponding to resonance and anti-resonance frequencies and signal values at extremum frequencies related to resonance and anti-resonance frequencies of transducer natural oscillations.
EFFECT: high accuracy and reliability of determining parameters of piezoelectric transducers.
