ABSTRACT:
A measuring transducer includes a transducer housing, as well as an internal part arranged in the transducer housing. The internal part includes at least one curved measuring tube vibrating, at least at times, during operation and serving for conveying the medium, as well as a counteroscillator affixed to the measuring tube on the inlet-side, accompanied by formation of a coupling zone, and to the measuring tube on the outlet-side, accompanied by the formation of a coupling zone. The internal part is held oscillatably in the transducer housing, at least by means of two connecting tube pieces, via which the measuring tube communicates during operation with the pipeline and which are so oriented with respect to one another, as well as with respect to an imaginary longitudinal axis of the measuring transducer, that the internal part can move during operation in the manner of a pendulum about the longitudinal axis. The measuring tube and the counteroscillator are additionally so embodied and so oriented with respect to one another that both a center of mass spaced from the imaginary longitudinal axis of the measuring tube, as well as also a center of mass of the counteroscillator spaced from the imaginary longitudinal axis, lie in a common region of the measuring transducer spanned by the imaginary longitudinal axis and the measuring tube, and that the center of mass of the measuring tube is spaced farther from the longitudinal axis than the center of mass of the counteroscillator.
