ABSTRACT:
A rotary variable differential transformer has coil windings at an angle with respect to the longitudinal axis of the transformer and a core rotatable about this axis with end faces cut at projected angles therewith such that a rotation of the core varies the coupling between the primary and secondary windings. Amplitude and phase variations at the secondary windings are measurements of core rotation.
