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.

The present invention relates to a load cell for a scale having a monolithically configured measurement body that has a force reception section, a force introduction section, and a joint section arranged between the force reception section and the force introduction section, having at least one strain gauge arranged at the upper side on the joint section for detecting a stretching deformation of the measurement body, and having electronics that are arranged at the force reception side, that are at least partly arranged on a circuit board, and that have a memory in which calibration data of the load cell and/or a value for gravity are stored, wherein a hardware interface is provided via which the memory can be accessed and via which the calibration data stored in the memory and/or the value for gravity can be changed.

A parallel guide of a force transmission device has movable and fixed parallel legs, and first and second parallel guiding elements. Thin-point flexional bearings connect the parallel legs to the parallel guiding elements. The movable parallel leg is guided by the parallel guiding element on the fixed parallel leg. A force transmission lever, arranged on the fixed parallel leg, has a lever bearing, and a first lever arm. The force transmission lever is pivotably mounted on the lever bearing and the first lever arm is connected to the movable parallel leg to transmit force. The force-transmitting connection is produced by a coupling element having at least one further thin-point flexional bearing, with at least one functional region of the force transmission device being formed monolithically. A functional region associates at least one bearing point with at least one of the parallel legs, the force transmission lever, and the coupling element.

An electromagnetic force-compensation direct measuring system (100) has a load receiver (101), which is connected to a force-compensation device (120) via a power-transmission linkage. The system has a multipart parallel guide mechanism, which has at least two parallel-guiding members (131, 132) spaced apart by the power-transmission linkage. The force-compensation device has at least one permanent magnet (121) and a coil (122) electrically connected to a controllable electrical circuit. At least one parallel-guiding member is electrically integrated in the controllable electrical circuit. The power-transmission linkage is designed as a single-part coil body (110) such that the coil is arranged on the coil body between the parallel-guiding members and is electrically connected to the controllable electrical circuit.

A weigh module (100) comprises a load cell (4), a supporting member (1), a connecting member (23) and a sealing member (3). The supporting member (1) comprises a receiving hole (13) extending vertically and thoroughly. The connecting member (23) comprises a fixing end (231) fixed to the load cell (4) and a limiting end (232) extending into the receiving hole (13). The limiting end (232) is configured to prevent the supporting member (1) from getting rid of the connecting member (23). The sealing member (3) comprises a first end (311) fixed to the supporting member (1), a second end (321) fixed to the load cell (4) and a raised portion (323).

A weigh module (100) comprises a load cell (4), a supporting member (1) and a guiding arrangement. The supporting member (1) comprises a receiving hole (13) extending vertically and through the supporting member (1). The guiding arrangement comprises a connecting member (23) and two parallel inner faces (611, 612) defined in the receiving hole (13). One end of the connecting member (23) is fixed to the load cell (4) and another end of the connecting member (23) extends into the receiving hole (13). The connecting member (23) cooperates with the two inner faces (611, 612) whereby the supporting member (1) can substantially move in a direction parallel with the inner faces (611, 612).
