The working principle of the MRT10-S is that when the wire rope passes through the sensor quickly, the magnet in the sensor magnetizes the wire rope in the axial depth and reaches saturation. The magnetic signal diffused to the space is accumulated by the concentrating ring, and is converted into a Voltage change value by the array wide-angle Hall element group, and the analog-to-digital conversion is carried out through the AD interface, and the digital signal is compressed and then input into the PC. Real-time decompression processing by software based on 3D mathematical model. The changes in the internal and external wire breakage, corrosion, damage and metal cross-sectional area of the wire rope are displayed with clear quantitative values, and the diagnostic evaluation report of the safety and service life of the wire rope is proposed according to the current standard.
