Webb9 jan. 2024 · Since proving rings are operate with relatively small deflection to stay within their linear range, measuring the minuscule deflection of the ring – which is typically between 0.05 (1.25 mm) to 0.10 inch (2.5 mm) under full load for a medium-size unit – requires a unique, non-obvious approach. WebbELE Proving Rings are available in the range of 450 lbf (2 kN) to 11,200 lbf. (50 kN). Both analog and digital models are available. The repeatability of all models of Proving Ring is within 0.2% of the indicated load and the accuracy is +/- 1% of the indicated load over the upper 80% of the working range at the calibration loads.
