Abstract :
This work presents the compact radial-axial 3D PCB capacitive position sensor. The FEM model, numerical analysis and prototype verification are presented. The capacitances of circuit are estimated using 3D model and are verified based on spectral analysis. The open and closed-loop measurements prove feasibility in applications related to rotating machinery.
