Abstract
A linear variable phase transformer position to phase transducer produces a linear phase change in an output signal with respect to displacement. Moreover, the magnitude of such output signal remains relatively constant while such displacement occurs. The transducer includes two primaries which are specially wound according to sine and cosine functions and are excited out of phase, a secondary, and a core that combines the primary signals and induces the output signal in the secondary according to the core position relative to the primaries.
