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.
