| 发明名称 | Magnetic circuit device for a magnetic-inductive flow meter | ||
| 摘要 | A magnetic circuit device (1) for implementing the magnetic circuit of a magnetic-inductive flow meter (12) has at least one coil (2b) which generates a magnetic field, at least two opposing flat pole elements (3a, 3b), between which, in the installed state, the measurement tube (13) of the magnetic-inductive flow meter is located, and with at least one magnetically conductive connecting element (4a, 4b) for magnetic closure of the magnetic circuit. The cross section of the core (2a) of the coil (2) and/or of the magnetically conductive connecting elements (4a, 4b) is as small as possible. Preferably, the magnetically conductive connecting element or the magnetically conductive connecting elements (4a, 4b) are arc-shaped so that the resulting magnetic circuit device (1) has a ring-shaped outer contour and extensively encompasses at least one of the flat pole elements (3a, 3b). | ||

| 主权项 | 1. A magnetic circuit device for implementing a magnetic circuit of a magnetic-inductive flow meter, comprising: at least one coil and coil core for generating a magnetic field, at least two opposing flat pole elements between which a measurement tube of the magnetic-inductive flow meter is located in an installed state of the circuit device in a magnetic-inductive flow meter, and at least one magnetically conductive connecting element for magnetic closure of the magnetic circuit between the pole elements, wherein at least one of the core and the at least one magnetically conductive connecting element has a cross section that is as small as possible without leading to saturation. | ||
