Title:
WIRE ROPE INSPECTION DEVICE AND WIRE ROPE INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/053512
Kind Code:
A1
Abstract:
A wire rope inspection device (101) comprises: a magnetizing coil (11); a detection unit (20) including a first detection coil (21) and a second detection coil (22); and a detected signal processing unit (33) that processes signals detected by the first detection coil (21) and the second detection coil (22). Each of the first detection coil (21) and the second detection coil (22) has one side connected to a shared reference potential and the other side connected to the detected signal processing unit. The detected signal processing unit (33) obtains a value based on the sum of the detected signals of the first detection coil (21) and the second detection coil (22) that are connected to the shared reference potential.
