Computerized Measurement, Display and Analysis of Sonar Transducer Equivalent Circuit Parameters
Abstract
Certain measurements of the electrical and mechanical properties of transducers are of importance to designers. These can be determined from accurate complex admittance and impedance measurements made throughout the frequency range of interest. Manual collection of needed data is a time- consuming process that is prone to error. The computerized system herein described substantially reduces the time requirement and produces more accurate output than can be obtained utilizing manual methods. In addition to a general discussion of equivalent circuits and the instruments employed, this report includes samples of plots and calculated parameters for piezoelectric and magnetostrictive transducers, the experimental comparison with traditional manual methods and the program listing for two versions of the system allowing varying amounts of operator options.
