Metal detectors can be classified as sensors, primarily because they are used to detect or sense the presence of a metal. Metal detectors are mainly used in industries and for security reasons. A closer look at the history of metal detectors reveals that these gadgets have been around for a long time. It is only recently that their uses have evolved to match the ever-changing technological demands.
How do Metal Detectors Work
Any metal detector you see employs a principle known as electromagnetic induction. This principle is all about the creation of an electromagnetic field around the metal detector. Any metal in this field disturbs the magnetic field and is in turn detected. With technology, the effectiveness and compact nature of metal detectors have been improving over the years.
When it comes to security, detectors come into man types; walkthrough detectors and handheld probes. In light of this, here are some of the three main ways that metal detectors are used today.
Metal detectors are an essential accessory for treasure hunters. For most treasure hunters, their main goal is to find a treasure that will see them get rich in an instance. Metal detectors, thus, can be used in locating gold and other precious metals. Looking at the stakes involved in treasure hunting, most treasure hunters tend to invest in top-of-the-range metal detectors to improve their chances of getting the right treasures.
Metal detectors have been used in the construction industry for a very long time, and this is not expected to change any time soon. When building a new structure or planning to reinforce an existing one, for instance, a metal detector can be used to probe whether the metal structure exists or not. Engineers need to know this, and this is why they make metal detectors their friends.
Acts of violence and terrorism can be reduced, to a large extent, through the use of metal detectors. In light of this fact, you will always see security personnel in airports, supermarkets, and some public places carrying some metal detectors as a way of enhancing security. It is worth noting that most people today identify metal detectors with security, and are not aware of the other ways these gadgets are used.
