ABSTRACT:
A method for manufacturing an ultrasonic transducer arrangement with groups of jointly controlled transducer elements, in which the metal coating of a contact foil is connected to a strip-shaped piezoelectric body, and the piezoelectric body, with the metal coating, is subsequently subdivided, in which the parts of the contact foil overhanging at the ends of the transducer elements are separated into contact tabs for individual transducer groups at both ends with one tab connected to a control conductor and the other tab forming electrically conducting bridges for the transducer elements of its transducer group. The bridges increase the operating reliability of the transducer arrangement produced, in that each transducer element is provided with an electrical lead at both its ends.
