摘要： A weighing system for a rotary rail car dumper. The rotary rail car dumper includes a frame assembly that receives a rail car including contents to be weighed. A series of trunnions are positioned to rotatably support the frame assembly and allow the frame assembly to be rotated to dump the contents of the rail car. A weight gauge is positioned on each of the trunnions. The weight gauge generates a signal based upon the force applied to the respective trunnion by the weight of the frame assembly and rail car. In one embodiment, the weight gauges are a series of strain gauges that generate an electrical signal based upon the force applied to the strain gauge. A control unit receives the electrical signals from the strain gauges and determines the weight of the rail car before and after the contents of the rail car have been dumped.
