摘要： 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 (10), which is connected through an upper guide (12) and a lower (11) guide to the housing-integral base body (1) of the material block. The weight sensor also has several force-reduction translating levers (21,22; 24, 25,25′; 27,27′,28) and coupling elements (18,18′, 23, 26,26′) between the translating levers (21, 22; 24 ,25,25′; 27,27′,28). The housing-integral base body (1) projects in the direction of the load receiver (10), extends into the space between the two guides (11, 12) and forms a support point for the first translating lever (21, 22). The weight sensor is equipped with a coil (34), which is fastened at the longer lever arm (28) of the last translating lever (27,27′,28,29,29′) 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 (25, 25′; 27,27′; 29,29′). At least one coupling element is split into two partial coupling elements (26,26′; 38,38′). The partial levers and the partial coupling elements are arranged symmetrically on both sides of the projecting part (3) of the base body (1).

摘要： A weighing system, using the principle of electromagnetic force compensation, which includes a permanent magnet system (14) having an air gap, a shielding cover (12), a coil (13) located inside the air gap, a transmission lever (7) to whose longer lever arm the coil is attached, and upon whose shorter lever arm the weight transferred by the load receiver acts, a position sensor (20, 21, 22) which detects the position of the transmission lever and which is situated in the vicinity of the coil, and a control amplifier (16) for controlling the current passing through the coil. Further, at least one vertical support (25) is connected to the transmission lever in the vicinity of the coil and the position sensor and projects through an opening (27) in the shielding cover. A counterweight (26) is placed on this/these support(s) closely above the shielding cover.
