An example actuator assembly includes an actuator configured to move a rod. A variable differential transformer (VDT) is situated adjacent to the actuator. The VDT includes a core coupled to the rod such that movement of the rod causes a corresponding movement of the core. A plurality of windings surround the core for measuring displacement of the core. A shield surrounds the plurality of windings and shields the plurality of windings from a magnetic field of the actuator. The shield having a maximum permeability of 50,000-500,000. A LVDT configuration method is also disclosed.
