FIELD: manufacture of weighers as a part of automated weighing systems. SUBSTANCE: automated weighing system has indicator interfaced with weigher controller, and keyboard connected in parallel with keyboard of weigher controller control unit. Introduced into weigher controller control unit are circuits OR NOT, NOT, OR, diodes and bidirectional switches using MOS structures. Arrester of the weigher intermediate mechanism is provided with a cam made in the form of a disk with recesses having nonlinear working surfaces, and a pawl, which comes in contact with the cam over the nonlinear working surface of recess at the moment, when the arrester opens, and over the working cylindrical surface of the disk at the moment, when the arrester closes.
