2800mm wide Needle metal detector for cloth

Needle metal detector for cloth

The needle metal detector is a portable instrument used to find and identify ferromagnetic metals. The instrument consists of a coil and an electronic circuit. The coil is made up of many turns of fine wire wound tightly around a core, usually a circular laminated iron core. The electronic circuit detects the electromagnetic field produced by the current flowing in the coil and produces an audible tone when it detects the field. A typical needle metal detector has a range of about one inch; this means that it can detect objects within one inch of its surface.

Needle metal detector for cloth, also known as the needle metal detector and the needle sensor, is mainly used to detect the existence of hidden metal objects in the cloth. The main technology of this product is that it uses a high frequency alternating current signal to pass through the conductive materials of the object and detects its impedance change, so that it can identify whether there is any metal material inside. It has a wide range of detection (about 2mm), which can effectively avoid false identification.
