Ultrasonic device
First Claim
1. Ultrasonic device comprising at least one ultrasonic transducer and a probe having an active part adapted to be immersed in a medium, said active part including an adapter part having a surface for matching the impedance of said probe to the medium, said adapter part surface having an end face and said active part extending longitudinally between said end face of said adapter part and a limiting part beyond said active part, said probe being adapted to carry longitudinal ultrasonic waves and radial ultrasonic waves generated by said ultrasonic transducer, said limiting part being located at a node of the longitudinal ultrasonic waves and said end face being located at a peak of the longitudinal ultrasonic waves, the longitudinal dimension of said active part being such that in operation at least one peak of the radial ultrasonic waves will be formed along said active part intermediate said limiting part and said end face.

Abstract
An ultrasonic device comprises at least one transducer and a probe having a first active part adapted to be immersed in a medium, an adapter part for matching the impedance of the probe to the medium and an end surface on the adapter part adapted to emit ultrasonic waves longitudinally into the medium. The first active part lies between the end surface on the adapter part, at which is located a peak of the longitudinal ultrasonic waves, and a limiting part at which is located a node of the longitudinal ultrasonic waves. It comprises a second active part adapted to emit ultrasonic waves radially into the medium and at which is located one or more peaks of the radial ultrasonic waves.
