    • 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).
    • 一种称重传感器,包括固定到壳体的基座(1),经由两个臂(3,4)以可移位方式连接到基座的负载传感器(2),至少具有至少 一个杠杆并将作用在负载传感器上的负载传递到换能器(12,13),以及内置的校准配重(40),其可以降低到支撑区域(30/38)上,用于检查和/或校准 称重传感器的灵敏度。 支撑区域通过两个附加臂(21,22)以平行的方式被引导,并且经由联接元件(26)连接到杠杆系统(8 ... 11)的杠杆(9/39)。 称重传感器上的相对较大的载荷可以用相对较小的校准砝码来模拟,而不需要复杂的提升装置。 两个附加臂(21,22)一方面连接到支撑区域(30/38),另一方面连接到负载传感器(2),并且位于负载传感器(2)的相反侧 从杠杆系统(8 ... 11)。
