An Automated Immittance Measuring System for Electroacoustic Transducers
Abstract
A fully automated method of obtaining immittance loops of piezoelectric transducers has been designed to be utilized in conjunction with the Hewlett-Packard 4192A Impedance Analyzer. The algorithm determines the frequencies at maximum and minimum immittances, the series and parallel resonance frequencies, and the resonance and antiresonance frequencies as well as the mechanical quality factor of the element under test. The collected data are plotted in the form of either admittance or impedance loops with evenly spaced points. The program has been implemented successfully as a means to rapidly obtain the admittance information of various loaded and unloaded transducers and transducer elements.
