    Abstract: An arrangement comprising an ultrasonic transducer and a damping element with a longitudinal axis, which damping element connects the ultrasonic transducer with a housing- or measuring tube wall. The transducer has an end piece with a medium-contacting surface, from which ultrasonic signals are transferred into a gaseous or liquid medium. The damping element has at least two annular grooves and an annular mass segment arranged therebetween, characterized in that the damping element has a first eigenfrequency, in which the annular mass segment executes an axial movement parallel to the longitudinal direction of the damping element. This first eigenfrequency is the highest eigenfrequency, in the case that a plurality of eigenfrequencies are present, in the case of which the annular mass segment executes an axial movement parallel to the longitudinal direction of the damping element, and the damping element has a second eigenfrequency, in which the annular mass segment executes a rotary movement. This second eigenfrequency is the lowest eigenfrequency, in the case that a plurality of eigenfrequencies are present, in the case of which the annular mass segment executes a rotary movement, will and wherein the ratio of the first eigenfrequency to the second eigenfrequency is less than 0.75; and a field device of process measurements technology.
