• A metal detector is used to detect the metals.
  It can find the metals that are present in other metals or underground and can also find the metals that are not visible to the eyes in any way. Usually, metal detectors have a handle and a sensor and when they are moved over a surface, they detect the metal and either make a sound or move their needle as an indication. There are ‘walk-through’ metal detectors as well, they are installed at certain places to detect the metals.

Metal detectors contain an oscillator that produces current. This current produces a magnetic field when passed through a coil.

There are vast applications for metal detectors. They are used in mines for getting precious metals. They are used to find weapons that are kept hidden. They are also used to find metals in food. In the construction field, they are used to find pipes and wires in the walls, etc.

Metal detectors transmit electromagnetic fields to the ground through their coil. Metal comes within the range of that electromagnetic field, it will get energy and will retransmit its own electromagnetic field. The coil of the metal detector will send the other electromagnetic field and will give the signal. The minilab detectors are capable of detecting only the target metals.

There are different components of metal detectors which are mentioned below

• 𝐂𝐨𝐧𝐭𝐫𝐨𝐥 𝐛𝐨𝐱

The control box can be regarded as the basic component of metal detectors. All the electronics are present within it. Sending, receiving, and processing the signals, everything happens here.

• 𝐒𝐞𝐚𝐫𝐜𝐡 𝐜𝐨𝐢𝐥

The search coil sends an electromagnetic field to the surfaces and receives the retransmitted electromagnetic field from the metal objects.

• 𝐓𝐫𝐚𝐧𝐬𝐦𝐢𝐭 𝐞𝐥𝐞𝐜𝐭𝐫𝐨𝐦𝐚𝐠𝐧𝐞𝐭𝐢𝐜

The transmitted electromagnetic field provides energy to the target metal and helps detect it.

• 𝐓𝐚𝐫𝐠𝐞𝐭

A target is any metal that we have to detect through the metal detectors. It can be gold or weapons or anything.

• 𝐔𝐧𝐰𝐚𝐧𝐭𝐞𝐝 𝐭𝐚𝐫𝐠𝐞𝐭

Unwanted targets are the metals that we do not want to detect through the metal detectors. The metal detectors are set to ignore them.

• 𝐑𝐞𝐜𝐞𝐢𝐯𝐞 𝐞𝐥𝐞𝐜𝐭𝐫𝐨𝐦𝐚𝐠𝐧𝐞𝐭𝐢𝐜

The receive electromagnetic is the electromagnetic field that is received by the target metal.

• 𝐓𝐚𝐫𝐠𝐞𝐭 𝐫𝐞𝐬𝐩𝐨𝐧𝐬𝐞

When the metal detectors come in contact with the target metals they produce a response like sound or any visual display.

There are different factors which are in what in detecting metals

• 𝐅𝐫𝐞𝐪𝐮𝐞𝐧𝐜𝐲

That detection of metals greatly depends upon the frequency of metal detectors. Different frequencies are suitable for detecting the different metals. We can choose the metal detectors with a specific frequency, according to the metal we want to detect. Metal detectors with multiple frequencies are also available.

• 𝐆𝐫𝐨𝐮𝐧𝐝 𝐁𝐚𝐥𝐚𝐧𝐜𝐞

Ground balance is another factor in the world in detecting metals. All the minerals present in a specific ground will respond after coming in contact with the metal detectors. The sounds of these minerals can distract you from finding the target metals. The setting of the ground balance, in the metal detector, is a very useful feature that saves time.

The ground balance has the following three types

• 𝐌𝐚𝐧𝐮𝐚𝐥 𝐆𝐫𝐨𝐮𝐧𝐝 𝐛𝐚𝐥𝐚𝐧𝐜𝐞

In this type, the ground balance can be adjusted manually to avoid disturbance by the noise of the ground.

• 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐜 𝐠𝐫𝐨𝐮𝐧𝐝 𝐛𝐚𝐥𝐚𝐧𝐜𝐞

This type of metal detector automatically attains the required ground balance setting.

• 𝐓𝐫𝐚𝐜𝐤𝐢𝐧𝐠 𝐠𝐫𝐨𝐮𝐧𝐝 𝐛𝐚𝐥𝐚𝐧𝐜𝐞

The metal detectors keep on adjusting the ground balance setting which is an extremely useful feature. Minelab detectors are the most advanced metal detectors.

• 𝐃𝐢𝐬𝐜𝐫𝐢𝐦𝐢𝐧𝐚𝐭𝐢𝐨𝐧

The ability of metal detectors to identify the hit metal is called discrimination. When you know accurately what is the object, that is hit to the metal detector you can decide whether to dig the ground or not. Minelab detectors produce different target identification numbers and produce different target sounds after sending different types of metals.

• Metal detectors can detect metals up to certain depths
  The larger the diameter of the coil the larger the metal detector will be able to detect the metals. The other factors involved in detecting the target at a depth involve:
• 𝐓𝐚𝐫𝐠𝐞𝐭 𝐬𝐢𝐳𝐞

Large metals can be detected to more depths than the smaller target metals.

• 𝐓𝐚𝐫𝐠𝐞𝐭 𝐬𝐡𝐚𝐩𝐞

Some shapes can be detected too deep than others.

• 𝐓𝐚𝐫𝐠𝐞𝐭 𝐨𝐫𝐢𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧

The horizontal metals can be detected to larger depths than the vertical ones.

• 𝐓𝐚𝐫𝐠𝐞𝐭 𝐦𝐚𝐭𝐞𝐫𝐢𝐚𝐥

The metals with higher conduction properties can be detected larger depth than the metals with poor conductive properties. you may also learn about the Fire Alarm Control Panel
