Abstract

Level sensors having conductive target movement sensing are disclosed. An example level sensor includes a lever operatively coupled to a sensing member, a target operatively coupled to the lever, where the target includes a conductor, an inductive coil to generate a magnetic field and measure feedback signatures associated with the target and the magnetic field, and a processor to calculate a position of the sensing member based on the feedback signatures.
