Abstract
An electronic sensor includes a signal generator configured to output excitation signals and a variable differential transformer connected to the signal generator to receive excitation signals. Embodiments of the variable differential transformer may include a primary coil, a first secondary coil connected to the signal generator, a second secondary coil connected to the signal generator, and a core disposed at least partially in a magnetic field generated via the first secondary coil and the second secondary coil and the first excitation signal and the second excitation signal. A phase of an output signal of the primary coil may correspond to a position of the core.
