Measuring tube for magneto-inductive flow-measuring systems

摘要

A measuring tube for magneto-inductive flowmeter systems, having a measuring tube for the flow of an electrically conductive medium and a magnetic field generating device for generating a magnetic field, at least two measuring electrodes which tap the measurement voltage induced in the electrically conductive medium and preferably an evaluation unit. The measuring electrodes have externally accessible measuring contacts, wherein the measuring tube forms a first functional unit with the measuring electrodes, and mating contacts corresponding to the measuring contacts of the measuring electrodes, the magnetic field generating device and an evaluation unit, if present, form a second functional unit. The measuring contacts of the measuring electrodes are provided on the measuring tube in such a manner that they can be brought into electrically conductive contact with the mating contacts by a movement which runs substantially perpendicular to the direction of the magnetic field and is substantially only translational.
