    摘要: 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).
