Method of the selection of ultrasonic transducers and transducers selected according to this method.

摘要

The invention relates to a method of selection of the ultrasonic transducers used in devices of the non-destructive ultrasonic. The method consists in establishing under determined conditions, the frequency spectrum of the transducer to be tested, to compare this spectrum to a reference spectrum, and to select the transducers which are identical to the reference spectrum.
