New core geometries to increase the sensing range of proximity transducers in general, and eddy current killed oscillator mode sensors, in particular. A theoretical analysis yields electromagnetic parameters that facilitate prediction of the sensing capability of any ferrite core geometry. The results of this analysis is applied to a multitude of Finite Element Analysis models to study changes in maximum sensing distance due to ferrite core geometry modifications. This yielded preferred embodiments for shielded and unshielded sensors.
