ABSTRACT:
A velocity sensor for sensing the speed of a moving conductive body employing an E-shaped magnetic core having a pair of spaced Hall effect devices positioned on the end of the central core, the ends of all cores being arranged adjacent to the path of the moving conductive body. The difference in output voltage registered by the two Hall effect devices is indicative of the speed of the conductive body.
