Metal Detector (MC14046-B) Circuit Diagram

Published:2011/6/23 8:42:00 Author:Vicky | Keyword: Metal Detector Circuit | From:SeekIC

Metal Detector is shown in the above picture. Detection coils constitute the LC oscillating circuit. When the coil gets close to the metal, the metal will generate eddy current inside, change the amount of coil inductance and thereby change the oscillating frequency of the detector circuit. Picture(a) is the functional block diagram of the detector and picuture(b) is the detecting picture.
