A weighing system, using the principle of electromagnetic force compensation, which includes a permanent magnet system (14) having an air gap, a shielding cover (12), a coil (13) located inside the air gap, a transmission lever (7) to whose longer lever arm the coil is attached, and upon whose shorter lever arm the weight transferred by the load receiver acts, a position sensor (20, 21, 22) which detects the position of the transmission lever and which is situated in the vicinity of the coil, and a control amplifier (16) for controlling the current passing through the coil. Further, at least one vertical support (25) is connected to the transmission lever in the vicinity of the coil and the position sensor and projects through an opening (27) in the shielding cover. A counterweight (26) is placed on this/these support(s) closely above the shielding cover.
