ABSTRACT:
An ultrasonic probe head, in particular for an ultrasonic flow meter having a housing and an ultrasonic transducer in the housing, wherein ultrasonic signals can be created and/or detected by the ultrasonic transducer and the ultrasonic signals from the ultrasonic transducer can be emitted and/or received via an ultrasonic window. A thin, relatively flexible solid interface layer is provided between the ultrasonic transducer and the ultrasonic window, the surface of the ultrasonic window having contact with the solid interface layer has a specified roughness and the ultrasonic transducer is impacted with a force, wherein the material of the solid interface layer and the ultrasonic window, the specified roughness of the surface of the ultrasonic window and the force are attuned to one another so that the solid interface layer nestles into the ultrasonic window of the housing at least also by plastic deformation. Thus, a passage is created between the ultrasonic transducer and the ultrasonic window that eliminates, at least partially, the known disadvantages between the ultrasonic transducer and the ultrasonic window.
