Abstract
An air-core transformer position sensor includes an excitation coil, an output coil, and a sensor coil. The excitation coil is adapted to be electrically excited with an excitation signal. The output coil is inductively coupled to the excitation coil upon electrical excitation of the excitation coil. The sensor coil is electrically shorted, is movable relative to the excitation coil and the output coil and, upon electrical excitation of the excitation coil, is inductively coupled to at least one of the excitation coil or the output coil.
