Modeling and characterization of LC displacement sensor in PCB technology

This paper presents the development of LC sensor comprised of a movable inductor and a fixed inductor-capacitor resonant circuit, thereby causing the sensor resonant frequency to be displacement dependent. The sensor has been fabricated in PCB (Printed Circuit Board) technology and experimentally ch...

Zusammenfassung:This paper presents the development of LC sensor comprised of a movable inductor and a fixed inductor-capacitor resonant circuit, thereby causing the sensor resonant frequency to be displacement dependent. The sensor has been fabricated in PCB (Printed Circuit Board) technology and experimentally characterized. Experimentally obtained results are compared with an electrical model. Good agreement between measured results and parameters estimated by analytical calculations are obtained.
