What makes a metal detector a good metal detector?
A basic approach to creating a superior metal detector includes: 1. Products that offer the most useful features and best possible performance 2. Products that are highly reliable 3. Products that exceed expectations every time they are used.
How does a metal detector work on a proximity sensor?
Proximity sensor (TDA0161), is triggered by this LC cirucit if any metal is detected.The Proximity sensor will then turn on the led and produces alarm using buzzer. LC Circuit: LC circuit has inductor and capacitor connected in parallel.This circuit sarts resonating when there is same frequency material near to it.
What does a visual display on a metal detector indicate?
Most discriminating metal detectors also have a visual display which indicates properties of a detected metal target. Figure 1. Transmit signal, receive X and receive R at the receive coil, X magnitude, R magnitude. (The rates of change of magnitudes are exaggerated for the sake of clarity.)
Can a metal detector detect non ferrous metal targets?
As the vast majority of buried metal targets are ferrous, the most important capability of the discriminator is not to detect these targets, but only to detect sought targets; i.e. non-ferrous. This includes non-ferrous targets close to ferrous targets when the ferrous (+X) signal competes with the non-ferrous (-X) signal.
