Abstract. A possibility is demonstrated of checking piezoelectric unit with frequency variation measurement in ceramic element mechanical resonance region. Theoretical relations and experimental data are presented.
Keywords: piezoelectric ceramic element, electromechanical coupling coefficient, piezoelectric unit, frequency characteristic of conductivity, equivalent electrical diagram.
