Abstract
The magnetic circuit arrangement, which is preferably used in a fluid-measuring transducer, comprises at least one coil which is traversed in operation by a current. It further comprises two armatures that are fixed to two flow tubes vibrating in phase opposition. The coil is float-mounted by means of a holder to a double flow tube configuration formed by the flow tubes. The armatures are shaped and aligned relative to each other in such a manner that magnetic fields produced by means of the magnetic circuit arrangement are essentially concentrated within the magnetic circuit arrangement, whereby the latter is also largely insensitive to extraneous magnetic fields. The magnetic circuit arrangement is marked by a long service life and, particularly if the transducer is used for fluids with high and/or varying temperatures, by constantly high accuracy in operation.
