Can metal detectors detect needles?
by Dongguan Jindu Electronic Technology Co.,Ltd
To understand whether metal detectors can detect needles, one must first understand the technology behind metal detectors and the principles of how needles are detected.
Metal detectors are designed to detect metal objects. They do this by using a combination of electrical fields, magnetic fields, and sound waves. Metal detectors emit an electrical current that passes through a coil of wires. The current creates a magnetic field that is then picked up by a detector. When a metal object passes through this field, it disrupts the magnetic field, which sends a signal to the detector. This signal is then heard by the operator who can then identify the type of metal object.
Needles, however, are small, thin metal objects and are much harder to detect with a metal detector than larger objects. This is because needles have a small surface area, which makes them difficult to detect with a metal detector. Additionally, needles can be made of various metals, such as steel, copper or aluminum, which can further complicate the ability to detect them.
In order to detect needles, specialized metal detectors must be used. These metal detectors are designed to be sensitive to very small metal objects, including needles. These needle detectors are specifically designed to detect and identify needles and other small metal objects. They are usually highly sensitive and are able to detect even the smallest of needles.
So call needle detector, it special design for detect any broken needle/ pin or other metal fragment in textile, garment, shoe industry, widely applied to textile and non textile industries.
There are also different model of needle detector that applied to various type of fabric, textile products, shoe products.,etc for maximize the detecting performance.
