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 on an inlet side and an outlet tube piece on an outlet side; a counteroscillator, which is affixed to the measuring tube on the inlet and outlet sides to form coupling zones; an cantilever coupled with the measuring tube on the inlet side; an cantilever coupled with the measuring tube on the outlet side; a sensor arrangement secured, at least in part, to the counteroscillator for registering oscillations at least of the measuring tube; an exciter mechanism secured, at least in part, to the counteroscillator for driving at least the measuring tube; a transducer housing affixed to the inlet tube piece and to the outlet tube piece; as well as connection lines, of which at least one is secured at least pointwise to the transducer housing and at least pointwise to an inner part of the measuring transducer formed by means of measuring tube, counteroscillator and the two cantilevers. A section at least of the one connection line extends freely suspended between two mutually spaced tie-down points. One of the tie-down points is located on the inner part of the measuring transducer and the other on the transducer housing. The two tie-down points are so placed that a relative distance therebetween remains essentially unchanged, even when the measuring tube is vibrating.
