Abstract
An ultrasonic transducer for an ultrasonic flow measuring device, comprising a first housing part having an ultrasonic window and adjoining, rotationally symmetric walls, wherein there adjoins on the walls of the first housing part, coaxially with the walls of the first housing part, a first ring as resonator, which forms an end of the first housing part.
Claims14
An ultrasonic transducer for an ultrasonic flow measuring device, comprising:
- an electromechanical transducer element for producing an acoustic signal with a predetermined excitation frequency;
- a first housing part having an ultrasonic window and adjoining, rotationally symmetric walls;
- and
- a first ring, wherein:
- there adjoins on the walls of said first housing part, coaxially with the walls of said first housing part, said first ring as a resonator, which forms an end of said first housing part, said resonator serves for suppression of the transmission of body sound waves.
