Patent ID: 7665369

Claim:
Measuring transducer of vibration-type for a medium flowing in a pipeline, said measuring transducer comprising: a measuring tube vibrating, at least at times, and serving for conveying medium to be measured; a counteroscillator affixed on an inlet-side to the measuring tube, to form a first coupling zone, and on an outlet-side to the measuring tube, to form a second coupling zone; an oscillation exciter for producing mechanical oscillations at least of the measuring tube relative to the counteroscillator; and a first oscillation sensor for registering oscillations at least of the measuring tube relative to the counteroscillator, said first oscillation sensor including a coil, a magnet cup composed at least partially of magnetically conductive material, and a permanent magnet placed within said magnet cup and magnetically coupled with the coil; wherein: the magnet cup includes a cup base and a cup wall extending from said cup base and said magnet cup being, and the cup wall of the magnet cup shows at least one slit.
