ULTRASONIC TRANSDUCER FOR USE IN AN ULTRASONIC FLOWMETER OR IN AN ULTRASONIC FILL STATE MEASURING DEVICE

摘要

The invention relates to an ultrasonic transducer (3) having a housing (31), in which a transducer element (11) for producing and detecting ultrasonic signals and an acoustic transformer (12) are arranged, wherein the acoustic transformer (12) is acoustically and mechanically coupled to the transducer element (11). The housing (31) has at least one housing body with at least one housing chamber (32) having a housing wall (33), the housing wall (33) enclosing at least in sections the acoustic transformer (12), wherein the housing is acoustically and mechanically connected to a measuring tube wall or a container wall, and wherein the acoustic transformer (12) is mechanically connected or connectable to the housing (31) via a lateral surface (M) of the acoustic transformer (12) by means of a first acoustic, in particular ring-shaped insulation.
