| Abstract: | Based on the principle of leakage flux test for broken wires in wire ropes, the characteristic parameters with single Hall element including the longitudinal resolution, the signal-to-noise ratio of testing signals and the formula for the optimum number of Hall elements are derived when the elements arrary is installed uniformly around the periphery. The combined test method with multiple elements for improving the signal-to-noise ratio of testing signals and reducing the number of output channels as well as the optimum combining the installing method of Hall elements is proposed. |
