ABSTRACT:
A differential transformer is provided comprising an elongated secondary winding of uniform turn density. First and second transformer primary windings are wound about the secondary winding. The primary windings lie generally in parallel spaced apart planes which cut the axis of the secondary winding at an angle other than 90.degree.. A core of magnetic material is movable linearly along a path parallel to the secondary winding axis and serves to couple the primary and secondary windings. The primary windings are connected to AC sources which are 90.degree. out of phase with each other.
