Characterization of inductive changes by resonant circuit technique

This work focuses on measuring precise values of passive elements such resistors, inductors and capacitors through non-contact means through inductive coupling for series and parallel. Resonant circuit is used for selective identification of high frequency components. However, if one of the circuit components such as the inductance, capacitance or resistance is made to vary, it will cause a change in the impedance output. The Device Under Test (DUT) is measured by sending an input signal through one inductive coupling and measuring the same received through another inductive coupling. Finally in the form of results, the procedure is shown to be consistent with traditional measurement methods. This change in the resonant frequency can be used to know which one of the circuit (series and parallel) or passive component will generate resonant coupling quickly and impedance highly. It also can used in some practical applications such as the inductive pressure sensor.
