Abstract (en)
The device has a solenoid wound around a haulage cable, in which a current impulse passes through the solenoid to magnetize a specific-point at the haulage cable for setting a bench-mark in the cable. The haulage cable is demagnetized when an alternating current flows through the solenoid. The specific point that is magnetized is detected by magnetic field sensors that are arranged around the specific point.
