ABSTRACT:
A rotary differential transformer is provided which has a constant amplitude output the phase angle of which varies with the angular displacement of a rotor. The rotor contains a pair of core segments of magnetic material which serve to couple portions of first and second primary coils to a secondary coil. The primary coils are connected to AC sources 90.degree. out of phase with each other.
