A conveyor system features a driven drive shaft, or other shaft, to which is mounted a speed sensor 20, made up of a plurality of Hall Effect sensors 24. A magnet 22 may feature at the centre of the shaft. The system finds application in the measuring of low speed conditions, around the 3-5 rpm mark, which may indicated a problem in the mechanical operation of the conveyor, upon which a control signal from a controller, may shut down operation of the conveyor. |
