In a weight sensor operating according to the principle of electromagnetic force compensation, the essential parts are fabricated from a single block of material. The weight sensor has a load receiver ( ), which is connected through an upper guide ( ) and a lower ( ) guide to the housing-integral base body ( ) of the material block. The weight sensor also has several force-reduction translating levers ( ) and coupling elements ( ) between the translating levers ( ). The housing-integral base body ( ) projects in the direction of the load receiver ( ), extends into the space between the two guides ( ) and forms a support point for the first translating lever ( ). The weight sensor is equipped with a coil ( ), which is fastened at the longer lever arm ( ) of the last translating lever ( ) and is situated in the magnetic field of a permanent magnet. To reduce the overall height and to receive higher loads, at least one translating lever is at least partially split into two partial levers ( ). At least one coupling element is split into two partial coupling elements ( ). The partial levers and the partial coupling elements are arranged symmetrically on both sides of the projecting part ( ) of the base body ( ).
