Abstract: A method for producing a force-measuring element (10) having at least one articulation point (20) which separates one region of the force-measuring element (10) into two connected subregions (11, 12) which can be deflected in relation to one another. The method includes: providing a force-measuring element blank (10), removing material from the force-measuring element blank (10) in order to produce the articulation point (20), checking whether the deflection behavior of the subregions (11, 12) which is produced by the articulation point corresponds to a predefined specification, defining a correction form (30) which can be produced through material removal and compensates for an ascertained deviation from the predefined specification, correcting the articulation point geometry using a laser and the previously defined correction form (30), through material removal at the articulation point.

Abstract: A top-pan balance having a pan, a weighing system, and an overload safety mechanism. The load cell (4) of the weighing system is connected to fixed points (1) on a housing of the weighing system by an upper connecting rod (2) and a lower connecting rod (3) as a parallel guide so as to be movable in the vertical direction. The pan is attached to a pan support (8/9) for securing against overload, the support being connected to the load cell through an auxiliary parallel guide (15/16) and through a biased spring element (17/18), whereby the pan is quasi rigidly coupled to the load cell in the permissible weighing range, but is only resiliently coupled to the load cell when the permissible weighing range is exceeded. At least one limit stop is fixed to the housing and limits the elastic deflection of the pan and the pan support in case of overload.

Abstract: A weighing system (1) with a plurality of weighing cells for respectively weighing a plurality of materials. The weighing cells have essentially the same configuration, are arranged interchangeably in a two-dimensional array, are releaseably fixed on a support element (6) and have electrical connectors.

Abstract: A weighing sensor including a base (1) fixed to a housing, a load sensor (2) connected to the base in a displaceable manner via two arms (3, 4), a lever system (8 . . . 11) having at least one lever and 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. The support region is guided in a parallel manner by two additional arms (21, 22) and is connected to a lever (9/39) of the lever system (8 . . . 11) via a coupling element (26). Relatively large loads on the weighing sensor may be simulated with relatively small calibration weights, without the need for complicated lifting devices. The two additional arms (21, 22) are connected on the one hand to the support region (30/38) and on the other hand to the load sensor (2) and are located on the side of the load sensor (2) opposite from the lever system (8 . . . 11).

Abstract: An apparatus for determining the position of the center of gravity of a test body with a test-body receiving plate supported on at least two weighing systems with short displacement in which device the position of the center of gravity is calculated from the particular bearing forces on the weighing systems that the connection between the test-body receiving plate (2) and the weighing systems (12, 13) takes place by means of coupling elements (22, 23) which are permanently connected by their one end to the test-body receiving plate (2), which are connected permanently by their other end to a weighing system (12, 13) and which are designed to be elastically flexible by means of at least one thin area (33, 34) defining a horizontal axis of rotation. This avoids an undefined introduction of force possibly overlaid by frictional forces and frictional moments into the weighing systems and thus increases the measuring accuracy.
