Long range metal detector circuit diagram.

The metal object has to be at a distance of 10mm for the detector to detect it. The following image shows the circuit diagram for the metal detector circuit. A distinctive feature of this device is the low operating frequency. Can be more sophisticated with different design and elements not available in electromagnetic metal detectors.

Metal detector circuit diagram the metal detector is a relatively simple device an electronic circuit that provides good sensitivity and stability. Long range gold detector circuit diagram. 1 x tda0161 proximity detector ic. Metal detector coil operates at a frequency of 3 khz.

May 19 2017 the post discusses a simple deep under soil metal detector circuit for evaluating hidden metals such as gold iron tin brass etc by detecting change in the resistance of the. Below is an example of a circuit diagram for a long range gold detector. This is nothing but a colpitts oscillator working in the medium band frequency and a radio tuned to the same frequency. The main disadvantage of this metal detector circuit is the range of detection.
