Abstract
A force exerted by a load is determined in a force-measuring device () operating under electromagnetic force compensation. The device includes a measurement transducer () with a coil () movably immersed in a magnet system () and a force-transmitting mechanical connection between a load-receiving part () and the coil or magnet system. A position sensor (), also part of the device, determines a displacement of the coil from its settling position relative to the magnet system () which occurs when the load is placed on the load-receiving part. An electrical current () flowing through the coil generates an electromagnetic force between the coil and the magnet system whereby the coil and the load-receiving part are returned to, and/or held at, the settling position. The magnitude of current and the amount of displacement are used to determine the weight force exerted by the load.
