Abstract (en)
[origin: ES8704360A1] 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.
