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.

摘要翻译： 根据电磁力补偿原理工作的称重系统具有两个作为平行导向装置的导向杆（12），该导向杆将负荷支承件（14）连接到固定在壳体上的基础区域（11），并且具有至少一个传动杆（17） 安装在底部区域上，并且由负载支撑件传递的重力经由耦合元件施加到其较短的杠杆臂，并且杠杆臂的较长的杠杆臂固定有线圈（18），该线圈伸入永磁体系统的气隙 （19）。 称重系统应该很窄，以便多个称重系统可以排列成彼此紧挨着的狭窄间隔排。 然而，永磁系统不需要与由基础区域，导杆，负载支撑件和传动杆构成的系统的主体一样窄。 为此，永磁体系统比系统主体宽，并且每个称重系统具有凹槽，相邻的称重系统（2）的永磁体系统（29）或相邻的称重系统的永磁体系统（29）可以投影到凹槽中 。 因此永磁体系统可以是系统主体的两倍。
