Detection of small metallic wear debris is critical to identify abnormal conditions for prognosis pending machinery failure. In this paper we applied an inductance–capacitance (LC) resonance method inductive pulse sensor increase the sensitivity. By adding external capacitor sensing coil sensor, a parallel LC circuit formed that has unique resonant frequency. At excitation frequency close frequency, impedance change (and thus in voltage output) caused by passage particle amplified due sharp...
