Metal Detector Malaysia
Metal Detector AD-4971 Series provides high sensitivity detection with simple and easy operation and contributes to the delivery of safe products to your customers.
You can conduct high sensitivity detection with simple and easy operation. The optimal sensitivity setting can be set through the auto sensitivity settings. The phase tracking function enables minimization of product phase and allows constant high sensitivity inspection.
The display utilises a high visibility touch panel color LCD with user friendly Graphic User Interface (audio guidance support function included).
Product images can be quickly uploaded to the metal detector from USB memory, making product identification and upload fast and simple.
Basic principle of metal detection
A sensor head of an electromagnetic induction type metal detector consists of a transmitter coil and two receiver coils that are equally spaced and are differentially connected. A transmitter coil broadcasts a radio frequency signal and generates an electromagnetic field between the transmitter coil and the receiver coils. When no contaminant exists, both receiver coils receive an equal amount of magnetic flux and differential signal output is balanced at zero.
The magnetic flux balance is disturbed and creates a differential output signal when a contaminant
passes through the aperture.
Metal detectors detect metal contaminants by processing this differential output signal.
