A metal detector is an electronic device used to detect traces of metal, usually of land, a person or cargo. Metal detectors can effectively penetrate soil, wood and other nonmetallic materials.

How it works

Metal detectors use principle of electromagnetism. Typically, a metal detector includes an electronic box, transmitter, receiver and antenna, a battery case. For energy battery, the transmitter generates a magnetic field. If an element of metal passes through the metal detector, which is magnetized by the magnetic field effect. Upon receipt electromagnetic signature, the receiver sends a signal to the electronic box. There is a loudspeaker to amplify this signal. This produces a sound which indicates that contamination by metals.

What are the different types of metal detectors?

Depending on specific situations, different types of detectors metal are available. For example, the exclusive metal detectors for gold prospecting. Also, special metal detectors are available for hunting relics. Underwater metal detectors, money detectors and walk through metal detectors are other prominent. Multi-purpose metal detector are also popular today.

What is the effect of the product?

Passing through the metal detector, some food products tend to generate a signal of metal, but is not present in them. This effect is called the product. This is mainly due to factors such as acidity, fat content, moisture content, salinity and temperature.

What are the factors affecting the sensitivity of metal detectors?

Effect of product size and type of metal contaminants, and metal detector aperture size are some of the factors affecting the sensitivity of the metal detector.

What is the heating time for metal detectors after the power is on?

For accurate detection of metals, metal detectors should allow hot at least 30 minutes after the phone is on.

It can burn and rustic metal detect using metal detectors?

Yes, however, the sensitivity of detection is based on the shape and orientation of the pollutants. It is hard to detect tiny particles.

They can detect metal detectors nonmetallic contaminants?

Metal detectors can not detect non-metallic contaminants.

What are necessary accessories in metal detecting?

Among the accessories needed for metal detecting are gloves, probe, knife, finder cayman and floor cloths.

What are the precautions to be taken when cleaning metal detectors?

To clean the main unit of the detectors metal, hot water below 40 degrees centigrade may be used. Dirt and particles in the detector should be cleaned frequently. It is also necessary cleaning their conveyors. Neutral detergent and a soft bristle brush with plastic can be applied for this purpose.
