Metal detectors

A typical metal detector used for detecting coins, gold, or landmines consists of a circular horizontal coil assembly held just above the ground.

There are two types of metal detector, classified by the type of magnetic field generated by the transmit coil.

1. Pulse induction (PI) detectors typically generate a transmitter current which is turned on for a time, and is then suddenly turned off. The collapsing field generates pulsed eddy currents in the target, which are then detected by analysing the decay of the pulse induced in the receiver coil.
2. Continuous wave (CW) detectors generate a transmitter coil current which alternates at a fixed frequency and amplitude. Small changes in the phase and amplitude of the receiver voltage reveal the presence of metal targets.

When you choose right metal detector, take a look at the next features:

Sensitivity and detection depth, robustness and reliability, endurance, immunity to electromagnetic interference, target localisation, target discrimination, detection depth and localization capability
