Abstract
A self-balance noise reduction metal detection double-coil comprises a main magnetic field transmitting coil and a plurality of induction coils. Each induction coil is composed of two inductors and induction unicoils in series connection, wherein the induction unicoils have similar Q values and are arranged in parallel. Every two adjacent induction coils are arranged in an overlapping mode. The multiple induction coils are arranged in the main magnetic field transmitting coil. The induction coils do not need to be adjusted, and the self-balance noise reduction metal detection double-coil is high in anti-electromagnetic interference capacity, unlikely to cause false alarms and free of weak induction zones, can normally operate in complex metal environments without being distributed, and is simple in structure, easy to machine and suitable for volume production.
