Industrial applications of metal and needle detector

Metal detectors are electronic instruments. These are used to detect the presence of metal particles and inclusions if these are hidden in any objects. Metal detectors can trace metal if those are buried underground. How? Here it is described below.

How do metal detectors work?
Every metal detector has a handheld part that has a sensor probe attached with. This sensor can be swept over the objects to find metal particles. When it comes near any metallic object, a change of tone is sounded on the earphones. If it is a needle detector then the user can see a needle to move on an indicator. The needle starts moving fast by getting closer to the hidden metal particle.

History of metal detectors:
Most of the people believe that metal detectors were invented in the 19th century as there are many proof remains of the successful industrial applications. But actually, metal detectors are a product of 1881. How? The great Alexander Graham Bell invented the first metal detector in the necessity of finding out a bullet from the abdomen of President James Garfield. Though it was a failure and he could not pinpoint the exact location for the bullet but his metal detector became a useful tool of the modern world.

Uses of metal detector:
Metal detectors have a huge use in security checking and in the medical, food, and mining industries. It can successfully detect landmines, and also a common choice for treasure hunting, archaeology, and geographical prospecting. Apart from the applications mentioned above, the textile and garments industries benefit heavily using needle detectors. How? The metal detecting devices use a needle here and the needle detection ensures that the garments remain free from all types of metal contaminants. This is crucial otherwise this can damage the whole business!

If a needle remains accidentally in a bundle of clothing, it can be taken under legal issues. This, in turn, reflects in the negative publicity of the manufacturer which may result in financial losses. It is one of the prime reasons why manufacturers and several brands invest heavily in using needle detectors and have severe metal contamination mechanism processes in place.

Needle detection in the garments industry:
With its years of use, needle detection has become a fundamental part of the process of garments production and accessories. Among all the types of garments and clothing, the department for infants strictly undergoes the metal and needle detection processes.

The two most commonly used needle detection techniques include handheld and conveyor type. All the recognized manufacturers of needle detectors in India efficiently ensure that no needles or broken tips or any type of metal contaminants remain in the garments.
