Abstract
A weighing apparatus of the electromagnetic load compensation type is disclosed, including a housing, a load receiver connected for vertical movement relative to the housing, a permanent magnet system connected with the housing for establishing a permanent magnetic field, and an electromagnetic compensating system including a compensation coil connected with the load receiver for movement within the magnetic field. The invention is characterized in that--in order to simplify manufacture and assembly while also achieving low structural height-the permanent magnet system includes a hollow sectional open-ended soft iron yoke member having a generally rectangular cross-sectional configuration, which yoke member is formed from a pair of longitudinally extending generally identical sections. At least one flat permanent magnet is mounted on the inner surface of the yoke member for establishing a flux path therein to generate the magnetic field.
