The ultrasonic transducer (1) has a housing (2) and an ultrasonic window (4) is provided in an area of the housing for transmission of ultrasonic waves between the interior and the exterior of the ultrasonic transducer. A transducer element (5) is arranged adjacent to the ultrasound window in the housing. Two slightly coupled mechanical resonators (8,9) are formed in another area of the housing. The resonators are arranged one behind the other in propagation direction of the housing waves (G). |
