摘要： An ultrasonic transducer for use in a fluid medium includes at least one transducer core having at least one electroacoustic transducer element, and further includes at least one housing having at least two housing parts. At least one first housing part at least partially encloses the transducer core such that a rear side of the electroacoustic transducer element which faces away from the fluid medium is accessible. Furthermore, at least one second housing part is connected to the first housing part. The ultrasonic transducer is essentially terminated by the second housing part on its side, which faces away from the fluid medium.
