ABSTRACT:
A movement detection system for use in measuring movements of a rotating body or shaft which is magnetized along an axis which is angularly displaced from the mechanical axis of rotation thereof. The system has a plurality of inductive coils which are connected to produce signals proportional to the movements of the body or shaft while suppressing spurious noise signals.
