摘要： A weighing system working on the principle of electromagnetic force compensation has two guide rods (12) which connect as parallel guides a load support (14) to a base region (11) fixed to the housing, and at least one transmission lever (17) mounted on the base region and to whose shorter lever arm the weight force transmitted by the load support is applied via a coupling element, and to whose longer lever arm is secured a coil (18) which projects into the air gap of a permanent magnet system (19). The weighing system should be narrow so that multiple weighing systems may be arranged in narrowly spaced rows next to each other. The permanent magnet system, however, should not need to be as narrow as the body of the system formed by the base region, the guide rods, the load support and the transmission lever(s). For that purpose, the permanent magnet system is broader than the body of the system and each weighing system has a recess into which the permanent magnet system(s) (29) of an adjacent weighing system (2) or of adjacent weighing systems can project. The permanent magnet system can thus be twice as broad as the body of the system.

摘要： A weighing system working on the principle of electromagnetic force compensation has two guide rods (4') which connect as parallel guides a load support (5') to a base region fixed to the housing, and at least one transmission lever (6') mounted on the base region and to whose shorter lever arm the weight force transmitted by the load support is applied via a coupling element, and to whose longer lever arm (7') is secured a coil which projects into the air gap of a permanent magnet system. The weighing system should be as narrow as possible while the length of the transmission lever and the space for the permanent magnet system should not be limited. For this purpose, the base region is subdivided into two separate sub-regions (2', 3'), the transmission lever (6') extends between these two sub-regions and two weighing systems are arranged next to one another and their base regions are interconnected in such a way that the two sub-regions (2, 3) of the base region of each weighing system fixes the two sub-regions (2', 3') of the base region of the other weighing system in their respective position relative to one another.

摘要： The invention relates to a force sensor with two force input elements (3,5/6), to which the force for measuring and the support force (11) are supplied, whereby both force input elements are embodied to be essentially rotationally symmetrical, separated in the axial direction and the force for measuring and the support force are introduced in the radial direction. A spring element (2), arranged in the axial direction between the both force input elements, connects the same and the load-dependent deformation thereof is converted into an electrical signal, for example, by means of strain measurement strips (25). According to the invention, a suppression of transverse forces can be achieved in a purely mechanical manner to such a degree that the influence of transverse forces on the output signal of the force sensor can be ignored, whereby the both force input elements (3,5/6) are additionally connected to each other by means of a guide element (42) which encloses the spring element (2) and which comprises two connectors (44) as parallel guide, significantly softer in the direction of the force (11) to be measured than in the direction perpendicular thereto.

摘要： The invention relates to a weighing system comprising a base region, a parallel-guided load sensor, at least one transmission lever that is pivotably mounted on the base region by means of at least one flexural pivot (3), and a coupling element that connects the load sensor to the short lever arm of the transmission lever. According to the invention, the flexural pivot (3), at least one part of the transmission lever (2), and at least one part of the base region (1') are monolithically formed from a block. The flexural pivot (3) is separated from the rest of the block by four horizontal, parallel boreholes (31, 32, 33, 34) that are adjacently arranged in an annular manner in such a way as to respectively leave a thin connecting segment (36, 37, 38, 39) between adjacent boreholes, and by additional slits. In this way, a hysteresis-free flexural pivot can be created, without requiring any assembly means.

摘要： The invention relates to a weighing system that operates according to the principle of electromagnetic force compensation, comprising two connecting rods that, in the form of a parallel guide, connect a load receptor to a housing-fixed base area, and comprising a bent lever mounted on the base area. The force due to weight that is transmitted by the load receptor acts upon the short lever arm of said bent lever via a coupling element, and a coil is fastened to the long lever arm, which projects into the air gap of a permanent magnet system. The aim of the invention is to provide a weighing system of the aforementioned type that occupies only a small area. To this end, the invention provides that the long lever arm (5 ) is provided in the form of a vertical lever arm and extends, at least in part, in the area underneath the connecting rods (2, 3) of the parallel guide, and that the permanent magnet system (7) is likewise arranged underneath the connecting rods (2, 3) of the parallel guide.

摘要： The invention relates to a weighing sensor comprising a piece (1), fixed to the housing, a load sensor (2), connected to the piece fixed to the housing in a displaceable manner, by means of two arms (3, 4), a pivot gear (8 11) with at least one lever, transmitting the load acting on the load sensor to a transducer (12, 13) and a built-in calibration weight (40) which may be lowered onto a support region (30/38) for checking and/or calibrating the sensitivity of the weighing sensor, whereby the support region is guided in a parallel manner by means of two further arms (21, 22) and connected to a lever (9/39) on the pivot gear by means of a coupling element (26). According to the invention, relatively large loads on the weighing sensor may be simulated by means of relatively small calibration weights, without the need for complicated lifting devices, whereby both further arms (21, 22) are connected on one side to the support region (30/38) and to the load sensor (2) on the side opposite to the pivot gear (8 11).
