Abstract
(DE)
Es wird eine Anregungseinheit (1) für einen Ultraschallsender vorgeschlagen, die einen Resonanzkörper (2) zur Festlegung einer Grundfrequenz der Anregungseinheit (1), ein Piezoelement (4) zur Anregung des Resonanzkörpers (2) und wenigstens ein Einstellelement (42) umfasst. Erfindungsgemäß ist das Einstellelement (42) an dem Resonanzkörper (2) zerstörungsfrei lösbar angeordnet. Weiterhin betrifft die Erfindung ein Verfahren zur Ultraschallprüfung eines Prüfobjektes.
(EN)
An excitation unit (1) for an ultrasonic transmitter is proposed, said excitation unit comprising a resonance body (2) for setting a fundamental frequency of the excitation unit (1), a piezo-element (4) for exciting the resonance body (2) and at least one adjustment element (42). According to the invention, the adjustment element (42) is nondestructively detachably disposed at the resonance body (2). Furthermore, the invention relates to a method for ultrasonic testing of a test object.
(FR)
L'invention concerne une unité d’excitation (1) pour un émetteur à ultrasons, comportant un corps résonnant (2) destiné à fixer une fréquence de base de l’unité d’excitation (1), un élément piézoélectrique (4) destiné à exciter le corps résonnant (2) et au moins un élément de réglage (42). Selon l’invention, l’élément de réglage (42) est disposé sur le corps résonnant (2) de façon amovible non destructive. En outre, l'invention concerne un procédé de contrôle par ultrasons d’un objet à contrôler.
