AI Technical Summary
The detection accuracy of existing magnetic sensor-based inspection devices for wire ropes in endless handrails is compromised due to varying overlap and separation of wire rope ends, leading to either strong magnetic fields exceeding sensor limits or reduced accuracy when widening the sensor range.
A tensile strength testing apparatus with a magnetic sensor, detection magnet, demagnetizer, and magnetizer that adjusts its operation mode based on the overlap or gap between wire rope ends, either demagnetizing or magnetizing the rope to manage magnetic fields effectively.
The apparatus maintains high detection accuracy by controlling magnetic fields, allowing for precise detection of defects in wire ropes with varying end configurations without needing to widen the sensor's detectable range.
