| Abstract: | Based on the principle of electromagnetic flaw detection, a new type of electromagnetic sensor for nondestructive testing of the broken strands in wire ropes using Hall elements as the detecting elements has been developed. The application of Hall elements in the test is discussed and the technical measures to improve the accuracy are suggested. A follow-up centering structure for the sensor is designed. By this structure, the variation of radial clearance between the rope surface and the sensor can be automatically compensated. The noise will then be reduced and the stability of the detecting signal guaranteed. Several Hall elements are used in the sensor and the detecting signal is given by multichannel output. The flaw detection resolution is found to have been considerably improved. |
