Abstract

An ultrasonic transducer includes at least one ultrasonic transducer element, a semiconductor chip that includes the ultrasonic transducer element, and a housing. The semiconductor chip is arranged in the housing. The semiconductor chip is embedded in a dimensionally stable encapsulation, wherein a contact surface of the dimensionally stable encapsulation is configured for acoustically coupling the ultrasonic transducer to a casing. Additionally, an ultrasonic transducer system and a method for fitting the ultrasonic transducer or ultrasonic transducer system are provided.
