ULTRASONIC CONTACT TRANSDUCER COMPRISING MULTIPLE EMITTING ELEMENTS AND MEANS FOR PRESSING SAID ELEMENTS

摘要

The invention relates to an ultrasonic contact transducer comprising multiple emitting elements and means for pressing said elements. The inventive transducer is particularly suitable for use for non-destructive testing purposes. The invention comprises means (8, 10) for pressing the emitting elements (2) against an object (6) that is to be tested and means (26, 28 and 34 to 40) for determining the positions of said elements in relation to the object, using the aforementioned press means, in order to establish the delay laws to be applied to pulses for excitation of the elements, such as to produce a focused ultrasonic beam (F).
