How Does a Metal Detector Work?

There are a number of people who do not really know how does a metal detector work? In a previous article, I talked about how exactly the technology works. So in this article, we are going to get to know how exactly the products work. But first let us know what a metal detector is.

A detector is a tool used for detecting the presence of metals. Metal detectors can detect metal from as far as a mile away. The presence of some substances present at the object’s location means that it is metallic. There are different types of metal detectors. The most common type of detector is the omni-directional detector. Omni-directional metal detectors are sensitive to a small area.

How does a metal detector work? Basically, a metal detector is a radio-controlled device that emits a particular frequency that is sensitive to metal. These devices usually have a scanning scope that is a dedicated crystal. Once the specific frequency is found, the scanner will locate the metal.

The technology of metal detectors was developed in the mid-19th century by Morse, Jones, and Slade. They had observed an open metal box emitting a magnetic field. These scientists were surprised to find that a metallic object or air was being disturbed by the field. They named the phenomenon the Faraday effect. The frequency was known as the ideal frequency.

By manipulating the length of the wire coils, scientists discovered that they could detect metal without the use of a metal box. In other words, they were able to detect metal objects far away. Wire coils were used to identify metal objects in the air. Today, these devices are used as direct-scan and sub-sonicreceivers. Since these types of detectors are quite sensitive, they can usually detect small particles like glass, plastic, stone, and dust.

How does a metal detector work? All radio-controlled detectors of today use either antenna design or electronic circuit design to generate a frequency. The field is sensed by a capacitor.

Technology has improved greatly in the last few decades. Now detectors can detect objects as far as one hundred yards. The technology is constantly improving. Just remember that you do not necessarily need a metal detector to perform your searches. You could utilize other types of detectors that are sensitive to other types of substances.
