ABSTRACT:
The measuring transducer includes at least one measuring tube communicating with a line connected during operation for conveying a medium to be measured, and a support element oscillatably holding the at least one measuring tube. Additionally, it is provided that the support element contains at least two passageways, via which the at least one measuring tube communicates with the line, and that the at least one measuring tube is affixed, especially releasably, at at least one end to the support element by means of a screwed-fitting at one of the passageways. Alternatively or in supplementation thereof, it is further provided that the at least one measuring tube is, at least in part, made of cold-strengthened, for instance cold-stretched or autofrettaged, material. As required, the measuring transducer can further include at least two measuring tubes communicating with the line for conveying the medium; each of these two measuring tubes is to be connected to an inlet-side distributor element and an outlet-side distributor element. In such case, at least one of the two distributor elements can be embodied as an integral component of the support element, so that the support element can be kept, at least in the area of this at least one distributor element, free of materially bonded, joined locations, especially free of solder, braze or weld connections. The measuring transducer of the invention is especially provided also for applications in which the medium to be measured acts with a pressure of more than 500 bar, especially over 700 bar, on the measuring tube.
