As the subject subtlely hints at, I’m using the 200kg load cell to make a big scale. The [Load Cell Hookup Guide was very helpful, but unfortunately the one type of load cell it did not include a setup picture for was the disc load cell.
I’m hoping for a little mechanical guidance. Say I have a 4x4 sheet of plywood or thin metal and I bolt my little disc load cell to the center. And then I set another sheet on top. How do I balance the corners? How do I best make sure the load is distributed as evenly as possible even if I don’t put my box or whatever right in the center of the scale? I thought I could winch down springs at each corner that would be pulling the top board down onto the load cell, then calibrate for that downward force. Can anyone think of a better way?
The lever might be 10ft long, a pivot on one end, load on the other, load cell in the middle.
200KG of load at the 10ft end, 100kg of load on the load cell.
But that invites the problem of the load being perfectly centered on the 10ft mark of the arm itself. Otherwise, you end up with some of that 200kg out at 11ft, some in at 9ft. Never mind.
Maybe you get 4 load cells for the load pad, one on each corner. Add them all up, do the math, you got your solution.
