ABSTRACT:
In one embodiment, a sensor assembly for measuring an angular position of a rotatable structure includes an annular ring that is eccentrically rotatable about an axis, a first and second sensors, and an sensor transducing circuit for combining the respective output levels from the two sensors. The first and second sensors are rotatable relative to the annular ring and disposed a predetermined distance from the axis such that the first and second sensors have a first and second output level respectively that is proportional to the angular position of the annular ring. The sensor transducing circuit is operable to proportionally combine the first and second output levels into an output signal based upon a weighting factor, the weighting factor being proportional to angular position of at least one of the first and second sensors.
