Abstract:
A measuring transducer includes: A measuring tube vibrating, at least at times, during operation and serving for conveying a medium, wherein the measuring tube communicates with a pipeline via an inlet tube piece at an inlet end and an outlet tube piece at an outlet end; a counteroscillator, which is affixed to the measuring tube on the inlet end to form a first coupling zone and affixed to the measuring tube on the outlet end to form a second coupling zone; and a transducer housing affixed to the inlet tube piece and the outlet tube piece. An exciter mechanism, for driving at least the measuring tube, and a sensor arrangement, for registering oscillations at least of the measuring tube, are, in each case, secured, at least in part, to the counteroscillator. Additionally, on the inlet side, an cantilever is so coupled in the region of the coupling zone with the inlet tube piece and the measuring tube, that the center of mass of the cantilever lies in the region of the inlet tube piece, and, on the outlet side, an cantilever is so coupled in the region of the coupling zone with the outlet tube piece and the measuring tube, that the center of mass of the cantilever lies in the region of the outlet tube piece. Furthermore, the measuring transducer includes connection lines, especially connection lines for the exciter mechanism and/or for the sensor arrangement, with at least one of the connection lines being secured to at least one of the two cantilevers.
