I recently bought this from an estate with a lot of machining equipment. It is used to measure the tensile forces. You can look up show distribution... they make equipment for the entertainment industry. Please email with any questions! Thanks for looking. The Dog Bone load cell improves upon the traditional load pin arrangement used to measure tensile forces on cranes, hoists, and other lifting devices. The unique shackle body design consists of dual sensing elements built into each leg of the shackle and provides accuracy up to 0.15% over ranges from 1,000 to 4000 lbs. Capacity of 4000 lbs Double strain gauge sensor Unaffected by side-loading Standard XLR-5 connector
