Description

For ultrasonic quantitative NDE, broad-band transducers with reproducible characteristics are needed. To design this type of a probe, one has to carefully match the electrical, mechanical and piezo-electric parameters of all its components. The most important point for a broad-band probe performance is the matching of a piezo-element with a damper. The main goal of this work was a study of physical aspects of the design of broad band ultrasonic transducers with reproducible parameters taking into account possible variations of geometrical, piezo-electrical and acoustical parameters of all the components. The analysis is based on the known equivalent electrical circuit model.
