Abstract: An inductive position sensor and method for detecting a movement of a conductive target, having: at least a first and a second transmitter coil having the same shape and which are phase-shifted to each other, at least one oscillator for generating a first and a second transmitter signal having the same shape and which are phase shifted to each other and are applied to the first transmitter coil and second transmitter coil respectively, at least one receiver coil, and a processing unit for determining a phase-shift between the first or second transmitter signal and a receiver signal received at the receiver coil; the determined phase-shift corresponding to the position of the conductive target above the first and second transmitter coils.
