Core position is detected by measuring the coils' differential reluctance using a sine wave excitation and synchronous demodulator. This differential detection method provides a very sensitive measure of core position while cancelling out temperature effects. The transducers' coils and Teflon cables are sealed in vacuum-pumped epoxy, within the stainless-steel case.
