Abstract

Es ist ein Schall- oder Ultraschallsensor zum Senden und/oder Empfangen von Schall oder Ultraschall vorgesehen, der mechanisch robust und chemisch beständig ist und der eine einstellbare Abstrahlcharakteristik aufweist, z.B. mit einem vorzugweise geringen Öffnungswinkel aufweist,
mit einem Abstrahlelement (3), das eine ebene Frontfläche (34) hat, und einem Wandlerelement (1), wobei das Wandlerelement (1) die Frontfläche (34) derart in Schwingungen aufgrund einer Anregungsfrequenz versetzt, daß die gesamte Frontfläche (34) nahezu gleichphasige Auslenkungen mit nahezu gleichgroßer Amplitude parallel zur Flächennormalen auf die Frontflache (34) ausführt und bei dem auf der Frontfläche konzentrische Stege (32),
angeordnet sind, wobei zwischen zwei benachbarten Stegen (32) jeweils ein konzentrischer Spalt (33) besteht und eine Scheibe (5) den Schall- oder Ultraschallsensor frontbündig abschließt, die fest mit den Stegen (32) verbunden ist und die nicht mit Stegen (32) verbundene, als Membranen (51) dienende Segmente aufweist.
