Abstract
A linear variable differential transducer (LVDT) includes a primary coil, a first secondary coil, and a second secondary coil. Each of the first and second secondary coils comprises a wound portion that is wound around a longitudinal axis of the LVDT, and first and second non-wound portions at either end of the wound portion. The wound portion meets the first and second non-wound portions at locations that are separated from each other in a direction along the longitudinal axis.
