Claim:
1. A sensor device for use in detecting current in a conductor, said sensor device comprising: a non-magnetic substrate defining an aperture through which a conductor is received; a coil comprising a plurality of turns wound about at least a portion of said substrate; and a housing enclosing said substrate and said coil, said housing including the aperture formed by said non-magnetic substrate and comprising: a dielectric material having a dielectric constant, said dielectric material positioned adjacent to said coil and at least partially within said aperture for said dielectric material to be disposed between said coil and said conductor when said conductor is received through said aperture; and an offset ring fitting within said aperture with an outer end of the offset ring projecting perpendicular to an outer face of said housing for said ring to be offset from said housing, said offset ring including at least one spacer extending between said offset ring and said conductor so to maintain a position of said coil relative to said conductor, said spacer extending into said aperture from said outer end of said offset ring so to be offset from said aperture, said offset ring ensuring that said sensor device is spaced a distance away from any object in a meter with which said sensor device is used.
