ABSTRACT:
An improved weighing apparatus of the electromagnetic load compensation type is disclosed, characterized by the provision of a horizontal one- or two-arm lever connected at one end with a compensation coil carrier device, a first bearing device connecting said lever for pivotal movement in a vertical plane relative to a pot-type permanent magnet, and a second bearing device connecting the pan carrier member with the lever. Preferably the first and second bearing devices comprise vertical flexible hanger straps that are bendable about parallel horizontal axes. In the one-arm embodiment, the lever is connected at its other end with the permanent magnet by the first bearing device, the pan carrier member being connected by the second bearing device to an intermediate portion of the lever. In the two-arm embodiment, an intermediate portion of the lever is connected with the permanent magnet by the first bearing device, and the other end of the lever is connected with the pan carrier by the second bearing device.
