Abstract

2.1. Die Erfindung betrifft einen piezoelektrischen Transducer für die Ultraschallerzeugung, insbesondere für die Ultraschallreinigung, mit einer Schwingplatte zur Übertragung von Schwingungen auf ein Fluid und mit wenigstens einem Piezoelement zur Ultraschallerzeugung mit einem einstückigen Körper aus piezoelektrischem Material mit einer ersten Oberfläche und einer zweiten Oberfläche, die im wesentlichen parallel zueinander angeordnet und wenigstens abschnittsweise mit einer elektrisch leitfähigen Beschichtung versehen sind, wobei das Piezoelement mit seiner zweiten Oberfläche auf der Schwingplatte aufliegt und mit dieser verbunden ist. 2.2. Erfindungsgemäss weist die elektrisch leitfähige Beschichtung der ersten Oberfläche wenigstens zwei elektrisch voneinander isolierte Elektroden zum Anlegen einer Betriebsspannung auf und die elektrisch leitfähige Beschichtung der zweiten Oberfläche ist elektrisch von der ersten und der zweiten Elektrode isoliert und wenigstens abschnittsweise gegenüberliegend der ersten und der zweiten Elektrode angeordnet. 2.3. Verwendung z.B. für Ultraschallreinigungssysteme.
