Abstract
Apparatus for weighing a billet adapted for use in conjunction with a billet manipulator. The weighing apparatus includes two or more cooperating billet weighing arms pivoted at one end to the billet manipulator which support the billet at their opposite end for weighing. Each arm has two planes of measurement spaced apart by fixed predetermined distance and the apparatus includes instrumentation which measures the bending moment on each arm at the two planes. The weight of the billet is proportional to the summation of the difference between the bending moments at the two planes for each arm and is independent of billet geometry or positioning of the billet on the apparatus.
