Abstract
An angular position sensor is provided with a rotatable magnetic structure that comprises a primary magnet and a secondary magnet. The primary and secondary magnets are adjusted in position relative to each other in order to achieve an adjustability of the gain and offset characteristic of an output signal from a magnetically sensitive component disposed within the magnetic field of the magnetic structure. The primary and secondary magnets are rigidly maintained in position relative to each other and disposed for rotation about an axis of rotation. Each magnet has a magnetic axis extending though its first and second magnetic poles. The two magnetic axes rotate within parallel planes that are each perpendicular to the axis of rotation of the magnetic structure. The gain characteristic of the output signal from the magnetically sensitive component can be advantageously affected by changing the linear distance between the first and second planes in which the first and second magnetic axes of the primary and secondary magnets rotate. The offset characteristic of the output signal from the magnetically sensitive component can be advantageously affected by changing the angular dimension between the first and second magnetic axes of the primary and secondary magnets.
