Title
(DE) BREITSTRAHLENDER ULTRASCHALLWANDLER
(EN) WIDE-RANGE ULTRASONIC TRANSDUCER
(FR) TRANSDUCTEUR D'ULTRASONS A LARGE BANDE
Abstract
(DE)
Breitbandiger Ultraschallwandler in Schichtbauweise, bestehend aus mit Elektroden versehenen Piezokeramiklamellen (2) und Platten/Schichten (3, 13), in Form eines Quaders mit einem Verhältnis Breite (B) : Länge (L) = 0,42, bei dem die Dickenverhältnisse der Piezokeramiklamellen und Platten/Schichten so bemessen sind, daß konphases Schwingungsverhalten einer seitlichen Fläche des Quaders erzielt ist.
(EN)
Disclosed is a wide-range ultrasonic transducer of sandwich construction, comprising piezo-ceramic laminae (2), fitted with electrodes, and plates/films (3, 13) in the shape of a parallelepiped with a width (B) to length (L) ratio of 0,42 and in which the relative thicknesses of the piezo-ceramic laminae and the plates/films are chosen such that one side surface of the parallelepiped undergoes co-phasal oscillations.
(FR)
Transducteur d'ultrasons à large bande en construction lamellaire, composé de lamelles piézocéramiques (2) munies d'électrodes et de plaquettes /couches (3, 13), sous la forme d'un parallélépipède avec un rapport Largeur (B): Longueur (L) = 0,42, dans lequel les rapports d'épaisseur des lamelles piézocéramiques et des plaquettes/couches sont dimensionnés de façon à obtenir un comportement oscillatoire en phase d'une face latérale du parallélépipède.
