Abstract

The ultrasonic transducer (5) is moved along the axial direction of elements of elongate shape (1), and is electrically excited for the emission of ultrasonic waves. Electrical measurement currents originating from the transducer (5) are collected and analyzed. The transducer (5) comprises a support having a concave active surface having curved generatrices and a plurality of piezoelectric elements fixed to the active surface of the support in adjacent dispositions.
