When a weight is applied to the weighing pan (1), it
moves down, guided by the parallel lever system (5). The
motion is transferred by the transmission lever (3) with a
specific ratio. A position detector (7) detects the displacement
x of the transmission lever. The position signal is
the input of the controller, which outputs a current I
through the coil of the electrodynamic actuator (8). The
resulting electromagnetic force compensates the
