Abstract
A method for aligning a sensor with a conductive material includes inducing a first magnetic flux in the conductive material to generate a first magnetic field state, and receiving a first signal at a first signal output level from a first detector and a second signal at a second signal output level from a second detector at the first magnetic field state. The method also includes inducing a second magnetic flux in the conductive material to generate a second magnetic field state, and receiving a third signal at a third signal output level from the first detector and a fourth signal at a fourth signal output level from the second detector at the second magnetic field state. Moreover, the method includes, based on changes in the signal output levels, adjusting a position of the sensor relative to the conductive target material to adjust the signal output levels to desired levels.
