A windshield structure (30) is provided for a weighing balance (100) having a base body (48), a floor (46), and a load receiving arrangement (11). The base body and the floor, which is attached to the base body, are positioned horizontal to the ground surface. The load receiving arrangement has a load receiver, with the windshield structure arranged below the load receiver. The windshield structure has a central portion and a circumferential portion that surrounds the central portion. The central portion also has a topological surface with a plurality of alternating hills (32) and valleys (31) which aid in regulating airflow below the load receiver.

A windshield for an electronic balance is provided which includes air cylinders incorporated inside as driving mechanisms, doors supported by a hanging manner by guide holes at least one end portion of which is open, and joint members interposed between the air cylinders and the doors. The joint members are also supported in a hanging manner in the guide holes, and upper portions of the joint members are joined to the air cylinders incorporated inside. The doors can be automatically opened and closed, and can be easily joined to and released from the driving mechanisms, and easily detached from the windshield by a simple structure.

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).

An integrated high-precision weighing module has a shell, an electromagnetic force sensor, a printed circuit board (PCB), a weighing pan component, a support ring, and an air baffle ring. The electromagnetic force sensor and the PCB are mounted in the shell. A bearing head of the electromagnetic force sensor extends upward from an upper end portion of the shell. The support ring sheathes the bearing head. The weighing pan component is mounted on the bearing head, with the support ring located between the weighing pan component and the shell. The air baffle ring is disposed around the weighing pan component and located on the support ring. A first airflow channel is formed among the shell, the support ring, and the air baffle ring. At least part of airflow in the shell flows to the outside through the first airflow channel.

The windshield includes an outer windshield defining a weighing chamber, and an inner windshield disposed inside the outer windshield and covering the weighing pan, the outer windshield includes a pair of left and right sliding doors openable and closable in side surfaces, and the inner windshield is provided with an opening in a surface facing one of the sliding doors, and a shielding wall is provided at a lower portion of the opening. An air flow generated when the sliding door of the outer windshield is opened or closed moves along a floor surface of the outer windshield toward the weighing pan, but is blocked by the shielding wall and does not flow into the inside of the inner windshield.

A gravimetric measuring system (10) includes a balance (12) with a weighing chamber (22), surrounded by a plurality of weighing chamber walls (23, 24, 26, 28); an electromechanical weighing system (181); and an electronic control apparatus (36) controlling the system operation according to routines stored in a memory (363) thereof; and a plurality of functional modules (14, 16), configured to be inserted into module receptacles, arranged on at least one weighing chamber wall (28). The at least one weighing chamber wall (28) is designed as a carrier structure, with recesses (283) which constitute clearances occupying a majority of the wall surface and which form the module receptacles. Either the functional modules (14, 16) or diaphragms (15) without a weighing function close the recesses and are spatially adapted to the recesses.

A gravimetric measuring system (10), includes a balance (12) with a weighing chamber (22), surrounded by a weighing chamber wall (23, 24, 26, 28); an electromechanical weighing system (181); an electronic control apparatus (36) for controlling the system operation; and a cooling apparatus (34), configured to be controlled by the control apparatus, for cooling the weighing chamber (22); and a plurality of functional modules (14, 16), which generate heat during operation and which insert into module receptacles (283), arranged on the weighing chamber wall (28). The module receptacles (283) have device-side thermal interface components (32a), which are thermally connected to the cooling apparatus (34), and the functional modules (14, 16) have corresponding, module-side thermal interface components (32b), which, in the inserted state of the respective functional module (14, 16), thermally contact the device-side thermal interface component (32a) of the respectively associated module receptacle (283).

A gravimetric measuring system (10) includes a balance (12) with a weighing chamber (22), surrounded by a plurality of weighing chamber walls (23, 24, 26, 28); an electromechanical weighing system (181), enclosed by an adjoining weighing system chamber (18); an electronic control apparatus (36) for controlling the system operation according to algorithms stored in a memory (363) thereof; and a plurality of functional modules (14, 16), which generate heat during operation and are configured to be inserted into module receptacles (283), arranged on at least one weighing chamber wall (28). A plurality of interacting measures lead to an advantageously controllable system that can be flexibly equipped, but is nonetheless calibratable.

Provided is an electronic balance that includes a windshield having a door to be automatically opened and closed, and has a high degree of freedom of design. An electronic balance including a balance main body that holds a weighing mechanism connected to a weighing pan, and a windshield including a frame and doors disposed slidably on the frame, and configured to form a weighing chamber by covering the weighing pan, and configured so that the windshield includes inside air cylinders connected to the doors to open and close the doors, and air pumps to drive the air cylinders, and is configured to be detachable from the balance main body. The windshield that has doors to be automatically opened and closed is detachable from the balance main body, so that the windshield and the balance main body can be designed separately, and therefore, the degree of freedom of design of the electronic balance is high.

An integrated high-precision weighing module has a shell, an electromagnetic force sensor, a printed circuit board (PCB), a weighing pan component, a support ring, and an air baffle ring. The electromagnetic force sensor and the PCB are mounted in the shell. A bearing head of the electromagnetic force sensor extends upward from an upper end portion of the shell. The support ring sheathes the bearing head. The weighing pan component is mounted on the bearing head, with the support ring located between the weighing pan component and the shell. The air baffle ring is disposed around the weighing pan component and located on the support ring. A first airflow channel is formed among the shell, the support ring, and the air baffle ring. At least part of airflow in the shell flows to the outside through the first airflow channel.
