Abstract:
1. An ultrasonic probe head, in particular for an ultrasonic flow meter having a housing and an ultrasonic transducer arranged in the housing, wherein ultrasonic signals are created and/or detected by the ultrasonic transducer and the ultrasonic signals from the ultrasonic transducer are emitted and/or received via an ultrasonic window, and wherein a thin, relatively flexible solid interface layer is provided between the ultrasonic transducer and the ultrasonic window of the housing, a contact 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, the improvement wherein the material of the solid interface layer and the ultrasonic window, the specified roughness of a contact 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 and wherein the contact surface between the solid interface layer and the ultrasonic window of the housing is as large as possible, in particular a maximum due to the plastic deformation of the solid interface layer.
