I have a 10klbs S shaped four wire load cell that I am going to be using to study dynamic loading on nylon ropes. Basically I am going to drop weights on various ropes and I need to record the maximum force the load cell experienced. I wanted to get a Daytronic 4077, it seems like it would be perfect for my application, however it requires a 120 VAC power source. Being that these tests will be conducted outside, away from buildings and power sources, I am trying to find a software application that I can use on my laptop. The program would have to have the ability to read a minimal of 1,000 samples per second as this is a dynamic loading scenario which will have a peak value lasting but a few milliseconds. Anyone have any ideas?
