A leading manufacturer of Trampolines for sports and fitness applications wanted to test the strength and longevity of the springs used to build the trampolines.  They turned to Loadstar Sensors' iLoad Mini Load Cells to test the Force vs. Deflection characteristic of the springs.  In addition they needed to see how well the springs held up after millions of cycles of load applied to them.  

So they built a testing machine that applied a tension and compression cycle every few seconds and applied this load to their springs in series with our iLoad Mini load cell.  

The results they got from the test helped them refine the design and ensure that their product would be a quality product that protected the safety of its users and also lasted for many millions of cycles of use with minimal sagging.
