Ultrasonic transducer for application in an ultrasonic, flow measuring device or in an ultrasonic, fill-level measuring device

Abstract

The invention relates to an ultrasonic transducer with a housing, in which a transducer element for producing and detecting ultrasonic signals and an acoustic transformer are arranged, wherein the acoustic transformer is acoustically and mechanically coupled with the transducer element. The housing includes at least one housing body, which has at least one housing chamber with a housing wall, which housing wall at least partially surrounds the acoustic transformer, wherein the housing is acoustically and mechanically connected with a measuring tube wall or a container wall and wherein the acoustic transformer is connected or connectable mechanically with the housing via a lateral surface of the acoustic transformer by means of a first acoustic insulation, especially an annular first acoustic insulation.
