Abstract

The 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; 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 the outlet tube piece; and connection lines, especially connection lines for the exciter mechanism and/or for the sensor arrangement, of which connection lines at least one is secured at least sectionally along the counteroscillator and secured at least pointwise thereto, as well as to the transducer housing. The connection lines are routed essentially symmetrically with respect to a principal axis of inertia of the inner part…
