摘要:
A measuring transducer includes: a measuring tube vibrating at least at times and serving for conveying medium to be measured; a counteroscillator, which is affixed to the measuring tube on an inlet-side, to form a first coupling zone, and to the measuring tube on an outlet-side, to form a second coupling zone; an exciter mechanism for driving at least the measuring tube; as well as a sensor arrangement for registering oscillations at least of the measuring tube. During operation, the measuring tube executes, at least at times and/or at least in part, bending oscillations about an imaginary bending oscillation axis, which imaginarily connects the two coupling zones with one another. Additionally, at least a first spring element and a second spring element are included, with each of the at least two spring elements being affixed to the measuring tube and the counteroscillator spaced both from each of the two coupling zones as well as also from the exciter mechanism.
