Linear Variable Displacement Transformer (LVDT) With Improved Linearity Using Extreme End Booster Winding

A linear variable displacement transformer (LVDT) position sensor. The position sensor comprises a bobbin, a primary coil of wire wound on the bobbin, a first secondary coil wound in stepped layers on the bobbin, and a second secondary coil wound in stepped layers on the bobbin. The first secondary coil comprises a plurality of booster windings at an end of the first secondary coil. The second secondary coil comprises a plurality of booster windings at an end of the second secondary coil opposite the end of the first secondary coil booster windings. The stepped windings of the second secondary coil are complementary to the stepped windings of the first secondary coil.
