Magnetizing device for a core magnetic flow meter

摘要

The device (1) has permanent magnets (2) for generation of magnetic fields, and a carrier (3) i.e. yoke, comprising a magnet retainer for retaining the permanent magnets. Molding of the magnet retainer and the permanent magnets allows a movement of the permanent magnets in a direction in the magnet retainer. The permanent magnets are held by the magnet retainer and arranged regarding the magnetic fields. The magnet retainer is designed as a hollow section (4), where friction is reduced during movement of the permanent magnets in the hollow section. The carrier is made of ceramic and/or composite glass fiber material and/or plastic.
