Patent ID: 8279428

Claim:
A weighing scale, comprising: a scale pan supported or suspended on at least one force transducer of a force measuring system and coupled to or comprising a reflecting surface, wherein the reflecting surface tilts in conformance with a tilting of the scale pan; a corner load sensor configured to measure the tilt of the scale pan relative to the force transducer, wherein the corner load sensor comprises: at least one light beam source configured to emit a first light beam and a second light beam toward the reflecting surface, wherein the first light beam and the second light beam are each inclined relative to a perpendicular of the reflecting surface in an untilted position of the scale pan; a first optical sensor toward which, in the untilted position, a predetermined portion of the first light beam reflected by the reflecting surface is directed; a second optical sensor toward which, in the untilted position, a predetermined portion of the second light beam reflected by the reflecting surface is directed; and an evaluating unit configured to determine the tilt of the scale pan in accordance with a light quantity measured with the first optical sensor and a light quantity measured with the second optical sensor.
