Flow-through pressure transducer

A measuring system for a physical variable, the measuring system comprising:

• a housing;
• a measuring tube comprising:
• at least one tubular deformation body having a cross-section which is deformed at least partially in a defined manner deviating from a circular cross-section and which is configured to expand elastically under pressure;
• two feed sections which are each attached to end sections of the deformation body and which each have a circular cross-section at outer edge sections thereof;
• two sealing sections for sealingly coupling the measuring system to a process, the sealing sections being integrally formed to the outer edge sections of the feed sections;
• and
• two molded support sections which carry the housing;
• a measuring sensor system configured to measure values of at least one of a stretching and a widening at at least two points on a section of the deformation body;
• and
• an evaluation unit configured to electronically evaluate measured values of the at least one of the stretching and widening and to output them as a measurement signal,
• wherein the housing at least partially surrounds and stabilizes the measuring tube on an outside in a direction of extension of the measuring tube, and
• wherein the feed sections are solid, and the feed sections comprise a transition of the inner contour from circular to oval.
