1. A weighing sensor for a scale, comprising a mainland body, a load receiver articulated on the mainland body by parallelogram guiding, and a lever mechanism having at least two levers which are supported on the mainland body by supporting joints, a first lever being arranged closer to a load receiver than a second lever, and the at least two levers being connected to each other via coupling rods and load joints, a calibration weight assembly comprising a calibration weight rest and a calibration weight being arranged on one lever, wherein the calibration weight rest is connected to at least one coupling element, wherein the calibration weight and a transfer mechanism for the calibration weight are arranged in front of the load receiver,
wherein the transfer mechanism raises and lowers the calibration weight, and
wherein the calibration weight rests on the calibration weight rest in a lowered state and has no contact with the calibration weight rest in a raised state.
