Abstract (en)
The transducer (1) has an adaptation layer (5) for acoustic impedance matching of a piezo-ceramic disc (3) at an environmental medium. The piezo-ceramic disc and the adaptation layer are embedded into a damping body (7). The layer is provided with a radiating surface (8), where a front side of the transducer with the radiating surface and a part of an upper surface of a cupular transducer housing (9) are coated with a parylene layer (11). The damping body is embedded into the transducer housing in such a manner that the radiating surface is free. Independent claims are also included for the following: (1) a method for manufacturing an ultrasound transducer (2) an ultrasound sensor comprising a housing (3) a method for manufacturing an ultrasound sensor.

Der Ultraschallwandler (1) und der Ultraschallsensor (13) umfassen einen Schutz gegen aggressive Chemikalien. Der Ultraschallwandler (13) ist mit einer Schutzschicht aus Parylene überzogen und wird innerhalb des Gehäuses (15) gegen einen an einem frontseitigen Absatz (25) des Gehäuses (15) anstehenden O-Ring (31) gepresst und in dieser Lage durch einen Pfropfen aus ausgehärtetem Giessharz gehalten.
