1.Measure and control angle 2.Non contact, no friction and long lifetime 3.Good frequency response

     Principle

As following figure shows, two doroid magnetic resistances form ring bridge structure. Hemicycle magnetic field generated by hemicycle permanent magnet is perpendicular to the plane where magnetic resistances are located. DC voltage Vin is applied on 1 and 3 terminals of magnetic resistance bridge. Each time permanent magnet turns around the axle center of ring magnetic resistance one cycle, one cycle of similar triangular wave signal (or sine wave ) will be output from 2 terminal and its effective linear range is 90°. Beyond 90°, the linear is not good
