Abstract
A sensor assembly for indicating the relative location of a metallic object. The sensor assembly including a primary electromagnetic coil arranged to generate a time varying magnetic field, and a secondary electromagnetic coil arranged to detect the time varying magnetic field as affected, directly or indirectly, by the object and to output, on the basis of the detected time varying magnetic field, a signal indicative of the relative location of the object. At least one of the primary and secondary electromagnetic coils is wound about a core body formed of a material having the same conductivity and/or magnetic permeability as the object.
