A position sensor has a moving coil part that is formed from a first coil form formed of a non ferromagnetic material, and a second coil that also has its form made of non-ferromagnetic material. The coil forms can be formed of non ferromagnetic adhesive. One of the coils moves relative to the other. The stationary coil part sufficiently close to said moving coil part such that magnetic flux from said moving coil part is induced into said stationary coil part. A primary coil is driven with a voltage. The operation senses voltages induced into a plurality of secondary coils, from movement of the primary coil relative to the secondary coils. The sensing can be done using a differential amplifier.
