A magnetic linear position transducer is proposed. It relies on a principle based on the variation of the magnetic flux distribution produced by the linear axial displacement of an ac-excited coil in a proper magnetic circuit. The principle and the correlation between the magnetic flux distribution and the linear displacement are demonstrated by a proposed linear reluctance network analytical model and by experimental results.
