Metal detector

Metal detector

A measuring device used to automatically check and detect metal objects mixed in non-metals. Electromagnetic induction is generally used for metal detection. The instrument usually includes a transmitter, a transmitting coil, a receiving coil, a receiver, an electronic measuring device, an alarm and an iron removal device. The transmitter transmits electromagnetic waves of a certain frequency through the transmitting coil, and the receiver receives the signal through the receiving coil and the inductive coupling of the metal object to be detected, thereby achieving the purpose of detection
