Metal detektor

The post explains a simple one transistor metal detector circuit which is very sensitive and and can detect any metal from a significant distance. We are

In contrast to the other metal detector in this issue, the present one works on the principle that the frequency of an LC oscillator changes when the inductance is altered. Any metal object brought near the inductor will modify the inductance. The degree by which the frequency changes depends on the nature of the metal and on the frequency. If the fre- quency is very high, a metal object will act as a shorted turn, which lowers the inductance, so that the fre- quency increases. If the…

Metal detector sensor is a special sensor or tools used in metal detectors contains special designed circuits for detecting of metallic objects underground

Metal Detector Technologies VFLEX Technology VFLEX uses state of the art digital electronics and signal processing to enhance conventional single frequency (VLF) metal detector technology. VFLEX provides increased detecting performance with perfect sine wave transmission, an in-coil signal booster and coil selectable t

The function of this adsorption type metal detector is to indicate the presence of ferrous and non-ferrous type metals. Its functionality depends on the
