ABSTRACT:
A weighing apparatus with electromagnetic force compensation is disclosed, including a load portion having a first compensation or load coil, and a reference portion having a second compensation or reference coil. An associated permanent magnet system is provided in the form of a partially closed housing having an intermediate wall on which flat permanent magnets are mounted, preferably in pairs. The load coil and the reference coil are arranged on opposite sides of the intermediate wall, thereby providing a compact arrangement which is easy to assemble and which has particular properties in regard to mutual decoupling of the two compensation coils.
