In a weighing sensor for a scale, comprising a base (), a load receiver () jointedly linked to the base () by means of a parallelogram linkage, and a lever mechanism having at least two force transmitting levers each having a load arm () and an force arm (), the force transmitting levers () being supported by means of supporting joints () defining supporting joint pivot points on the base (), and being arranged one behind the other as seen in the longitudinal direction of the weighing sensor, it is provided that all force transmitting levers () are two-sided levers.

Weighing sensor for a scale

The invention relates to a sealing mechanism for a scale, in which a connection element connected to a moving lifting element seals or opens an annular gap, wherein, for an opened annular gap, the connection element and lifting element form a biasing load for the weighing sensor of the scale.

Sealing mechanism

The above described preferred embodiments are intended to illustrate the principles of the invention, but not to limit the scope of the invention. Various other embodiments and modifications to these preferred embodiments may be made by those skilled in the art without departing from the scope of the present invention.

Weighing sensor with a serial arrangement of force transfer levers to obtain a compact load cell

A weighing sensor according to the principle of electromagnetic force compensation, wherein a stop is provided on the load receiver for a lever or a component carried by it.

Weighing sensor having a stop structure

A lever mechanism, particularly for a scale receiver of a scale that works on the principle of electromagnetic force compensation includes at least one lever which is connected to a stationary base body or an element connected to the base body. The at least one lever arm is connected to the base body or the element connected to the base body via an elastically deformable articulation which defines a swivel axis of the at least one lever. A load force (F), which corresponds to the weight force (F) or is derived therefrom, acts on a first lever arm of the at least one lever and generates on a second lever arm of the at least one lever a reaction three (F). The elastically deformable articulation comprises two thin, elastically deformable bending areas, which connect the lever to the base body or to the element connected to the base body. Each bending area is bendable in a direction that is perpendicular to a longitudinal extension plane defined by the geometry of the respective bending area, for the generation of a swivel motion of the at least one lever. The longitudinal extension planes of the bending areas enclose an angle (&#x3b1;) that is not equal to zero, and a virtual swivel axis (D) of the at least one lever is defined by the two elastically deformable bending areas.

Lever mechanism, particulary for a scale receiver of a scale that works on the principle of electromagnetic force compensation

A weight sensor includes at least one force-translating element cooperating in a levered manner in response to an applied load. The at least one force-translating element is arranged at least in part asymmetrically to an imaginary center plane of the weight sensor.
