Angular position sensor with adjustable gain and offset signal capability

An angular position sensor, comprising:

• a rotatable permanent magnet, said permanent magnet being attachable to a shaft;
• first and second ferromagnetic pole pieces, each of said first and second ferromagnetic pole pieces having a first end and a second end, said permanent magnet being disposed in spaced relation with said first and second ferromagnetic pole pieces between said first ends of said ferromagnetic pole pieces with a first gap disposed between said first ferromagnetic pole piece and said permanent magnet and a second gap disposed between said second ferromagnetic pole piece and said permanent magnet;
• a magnetically sensitive component disposed between said second ends of said first and second ferromagnetic pole pieces, said magnetically sensitive component having an output signal which is representative of the angular position of said permanent magnet;
• a first ferromagnetic insert which is variably disposable within said first gap;
• and
• a second ferromagnetic insert which is variably disposable within said second gap, wherein the positions of said first and second ferromagnetic inserts within said first and second gaps affects the magnetic field extending from said permanent magnet to said magnetically sensitive component, said first and second ferromagnetic inserts being threaded and movable relative to said first and second gaps in response to rotation of said first and second ferromagnetic inserts about their respective central axes.
