The second lever arm includes a first partial lever arm (482A) and a second partial lever arm (482B), wherein the first partial lever arm is designed to receive the compensation force generated by the measurement transducer, and the second partial lever arm is designed for the detection of a displacement of the pivotally supported force-transmitting lever relative to a null reference of a position sensor (420).

An inspection device for inspecting containers (100) comprises a rotary conveyor (2), provided with a plurality of receiving cavities (5), and a measuring station (400) configured to inspect each container (100) while the container (100) is being supported and moved by the conveyor (2), wherein the conveyor (2) has continuous motion and the measuring station (400) comprises a microwave detector provided with a measuring zone (410) through which each container (100) passes in order to generate an information item relating to at least one of the following: weight of the container (100) as a whole or of the dose of product contained therein, type of product inside the container (100), presence of foreign bodies in the container (100).

A monoblock sensor body of a load cell based on an electromagnetic force compensation mechanism has a Roberval mechanism. Mounting portions mount the fixed column to a housing side of a weighing module, and mount a load receiving member to the movable column. At least one of the mounting portions has at least one mounting hole that extends predominantly orthogonal to the load direction. One of the flexure point sections is closest to the mounting hole. A cavity associated with at least one of the mounting portions reduces an available solid angle for straight propagation paths that run from the inner thread to one or more of: the closest flexure point section, the coupling and the closest fulcrum. A material boundary of the body closes the cavity over at least a bridging width versus the height-side end of the body corresponding to the closest flexure point section.

A method and an apparatus for measuring mass based on torque equilibrium, including a main blade for supporting and balancing a lever and parts arranged on the lever; a displacement measuring device for measuring a position of the lever; an electromagnetic torquer for balancing the apparatus after a balance weight is coarsely loaded during measuring; a product tooling on which a product to be measured is arranged and fixedly connected. The product tooling is fixed on a slider which freely slides along a guide rail; a locking block is provided to lock the product after the product slides in place; the guide rail is fixed on the level; a laser displacement sensor is provided to measure a displacement of the product along the guide rail; a lifting mechanism is provided to lift the lever and parts arranged on the lever to separate from the main blade.

A weighing sensor and a lever are disclosed. The weighing sensor has a load-receiving portion, a fixing portion, and a parallel guiding portion connected to the load-receiving portion and the fixing portion. The parallel guiding portion has upper and lower parallel guiding units, separated from each other. The ends of the parallel guiding units are connected to the load-receiving portion and the fixing portion. The fixing portion has an extension located between the parallel guiding units. The extension is at a distance from both parallel guiding units and extends to the load-receiving portion. A gap is formed between the extension and the load-receiving portion; and the distance between the extension and the upper parallel guiding unit allows a lever to pass through. The weighing sensor has a simple structure, both the processing process and the assembly process are simplified, and the processing and assembly during production are facilitated.

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.
