Measuring transducer of a vibration-type having slits in the coupling elements for tuning eigenfrequency of the measuring tubes

摘要

A measuring transducer serves for producing vibration signals corresponding to parameters of a flowing medium comprises a measuring transducer housing having housing ends and, extending within the measuring transducer housing between its housing ends, a tube arrangement formed by means of at least two tubes. Of the two tubes, at least one tube serves as a measuring tube conveying flowing medium and the other tube is mechanically connected with the tube by means of a first coupling element to form an inlet-side coupling zone and by means of a second coupling element to form an outlet-side coupling zone. At least the first coupling element has in a region extending between the tubes a slit having at least one closed end. Slit has a maximal slit width and a maximal slit length, which is greater than the maximal slit width. Placed partially within the slit is a connecting element, which contacts a slit edge enclosing said slit.

1. A measuring transducer of vibration-type for producing vibration signals as a function of parameters of a flowing medium, said measuring transducer comprising:
a measuring transducer housing with a first housing end and a second housing end; and a tube arrangement extending within said measuring transducer housing from said first housing end to said second housing end, and formed by means of at least two tubes, of which at least a first tube, is embodied as a measuring tube serving for conveying flowing medium, and of which a second tube is connected mechanically with said first tube to form an inlet-side, first coupling zone by means of a first coupling element, and to form an outlet-side, second coupling zone by means of a second coupling element, wherein: in a region extending between said first and second tubes said first coupling element exhibits a slit with a maximal slit width and a maximal slit length, which is greater than the maximal slit width, and said first coupling element includes a connecting element, which is placed partially within said slit, said slit exhibiting at least one closed end, and said connecting element contacting a slit edge enclosing said slit, in order to form a securement zone, within which relative movements of said edge regions are prevented, in that said connecting element is affixed to said edge regions lying opposite one another.
