Abstract
In a weighing sensor for a scale, comprising a base (1), a load receiver (4) jointedly linked to the base (1) by means of a parallelogram linkage, and a lever mechanism having at least two force transmitting levers each having a load arm (14, 23, 28, 35, 39, 46, 54) and an force arm (19, 30, 38), the force transmitting levers (8, 9, 36, 40, 50) being supported by means of supporting joints (17, 24, 29, 37, 42, 48, 55, 60) defining supporting joint pivot points on the base (1), 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 (8, 9, 36, 40, 50) are two-sided levers.
Claims19
A weighing sensor for a scale, comprising:
- a base;
- a load receiver jointedly linked to the base by a parallelogram linkage;
- a lever mechanism including a plurality of force transmitting levers, each including a load arm and a force arm,
- wherein the plurality of force transmitting levers are supported by means of supporting joints including supporting joint pivot points on the base,
- wherein the plurality of force transmitting levers are arranged one behind the other as seen in a longitudinal direction of the weighing sensor, and
- wherein the plurality of force transmitting levers are two-sided levers;
- and
- at least one pair of a plurality of coupling elements that are arranged parallel to each other and arranged adjacent to each other and connected to a same arm which is one of a load arm or a force arm of one of the plurality of force transmitting levers, wherein the same arm protrudes into a coupling element space left between two coupling elements of the at least one pair of coupling elements.
