High Sensitivity - Low Capacity Load Cell with Overload Protection.
Abstract
Research in metalworking frequently requires utilization of a small fraction of the load capacity of the equipment. This situation can result from small workpieces because of limited amounts of experimental materials, prior deformation processing of ignots or constraints on experimental variables. Measurement of small loads can pose linearity and sensitivity difficulties when using load cells designed to accommodate full press capacity. A high sensitivity low capacity load cell was designed with a load measuring capability up to 110,000 lbs and capable of safely accommodating loads up to maximum press load (1.1 times 10 to the 5th power lbs). The load cell was built, instrumented with strain gages and calibrated up to 200,000 lbs on a certified testing machine. Flow stress-strain curves obtained from loads measured using the cell are shown. (Author)
