Abstract: A weighing chamber in a shape of a transparent cuboid with sliding panels (1, 2, 3, 4, 5) assembled on structural guides (8) that are fastened using at least a single adjustable lock (13) blocking at least one panel in a way that their releasing enables sliding and disassembling the other panels. The fastening lock forms a profiled element, preferably an angle bar shaped component assembled in a detachable manner to the horizontal structural beam (8). The chamber comprises two vertical columns (6, 7) assembled at the back corners of the chamber's interior which support the chamber structure (8) comprising a horizontal beam for assembling the fastening lock and guides for holding and sliding the top and side panels using grips (9, 10, 11).

Abstract: A balance base (5), under the weighing mechanism (4), features automatic mechanism for opening door of the weighing chamber. An electric motor (6) is coupled through a gear (8) with an arm (10) connected with the moveable frame (11) structure, that moves on rails (12, 13). The ratchet and pawl mechanism is related to the fastener knob (17) of the side doors enabling joining the doors with the moveable frame (11) and both opening and closing them by moving the arm (10) coupled with the motor (6) through a gear (8). The mechanism activation is controlled by the proximity sensors (12) located on balance's display housing (16).
