Abstract
The 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. Counteroscillator of the measuring transducer of the invention is formed by means of two counteroscillator plates, of which a first counteroscillator plate is arranged on the left side of the measuring tube and a second counteroscillator plate is arranged on the right side…
