Abstract
A system for monitoring at least one motion parameter of the main shaft of a gyratory or cone crusher. The system includes a sensor, such as a magnetometer, positioned within close proximity to a magnetic element, such as a lifting lug, formed on a top end of the main shaft. When the main shaft rotates or moves vertically, the movement creates a change in the magnetic flux, which is sensed by the magnetometer. The change in the magnetic flux is sensed by the magnetometer and an output signal is generated. A controller receives the output signal and determines at least one motion parameter based upon the detected changes in the magnetic flux. In one embodiment, a permanent magnet can be the magnetic element or can be inserted into the lifting lug to enhance the magnetic flux changes caused by the rotational movement or vertical movement of the main shaft.
