Mechanically adjustable current sensor and method for making same

A current sensor, comprising:

• a first lamina having a first gap formed in its circumferential length, said first gap being defined by first and second opposing faces which are spaced apart by a first preselected distance, said first lamina having a first planar surface;
• a second lamina having a second gap formed in its circumferential length, said second gap being defined by third and fourth opposing faces which are spaced apart by a second preselected distance, said second lamina having a second planar surface, said first and second laminae being associated together with said first and second planar surfaces disposed in contact with each other, said first and second laminae defining a central opening shaped to permit an electrical conductor to extend therethrough;
• and
• a magnetically sensitive device disposed in a space defined by said first and second gaps, said magnetically sensitive device being disposed between said first and second opposing faces and between said third and fourth opposing faces, said magnetically sensitive device having an output signal which varies as a function of magnetic flux density in said space defined by said first and second gaps, said magnetic flux density being a function of an electric current flowing through said central opening in said conductor and the size of said space defined by said first and second gaps, said first lamina being disposed relative to said second lamina to misalign said first and third faces by a predetermined distance which is determined as a function of the relationship between said current and said output signal.
