A Floating Wiper Inductive Voltage Divider Type Displacement Transducer

A novel, floating wiper, inductive voltage divider (IVD) type displacement transducer is presented here. A self balancing signal conditioning circuit, proposed herein, operates on an IVD with a floating wiper and provides an output that is proportional to the displacement (can be linear or angular) of the wiper. The output is made independent of the coupling capacitor that would arise due to the air gap between the inductive element and the floating wiper. Thus the output of the proffered transducer is unaffected by any jitter that may occur and alter the distance between the wiper and the IVD. The workability of the proposed transducer is extensively verified through simulation studies.
