Linierisasi Sensor Koil Datar Dengan Pengolahan Isyarat Metode Diferensial

Flat coil inductive sensor works by detecting changes in the magnetic field of an object without a physical contact with measuring object. This study use two flat coil sensor geometry circle on Printed Circuit Board (PCB) through the etching process with indutance of Hμ5.22and Hμ9.17respectively. Flat coil evaluation sensor using LC oscillator produces the eigen frequency of 1MHz up to 2MHz. …
