What Is a Metal Detector?
Metal detectors work by sending short bursts (pulses) of current through a coil of wire, creating an alternating magnetic field which interacts with any metal that conducts electricity, such as copper. Different metals respond differently to this field, which allows metal detectors to identify them more precisely.
Pulses from the transmitter coil are then reflected back into a receiver coil and detected, creating a signal that can be processed in a control box. The signal produced is an extremely brief electrical spike lasting only milliseconds; upon analysis if conductive metal contamination is identified it triggers an alarm; thus allowing removal from product stream before becoming part of any food products and thus protecting potential health and safety risks.
Metal detectors are usually placed at production points identified as crucial to product quality or to protecting expensive equipment from being damaged by metal. Some detectors are integrated directly with production lines while others can serve as standalone units to monitor incoming product. Detectors may be designed to respond only when large amounts of metal contamination is present or more sensitive detectors could also detect smaller amounts.
VLF technology is one of the most commonly used metal detection techniques. This system utilizes two coils - one on each end of an oscillating magnetic field - which sends short pulses of current into an environment and interacts with any metals present, creating magnetic fields which interact with them and cause them to cause changes in phase response and pulse length - this metal detector means longer reflected pulses mean there's likely some sort of metal nearby.
Pulse Induction or PI is another popular detector used in most walkthrough systems. As opposed to VLF which sends continuous waves of pulses, PI metal detector store near me detectors send short bursts of pulses before timing their reflection from decaying - this provides a good indicator as to whether metal exists or not.
Both VLF best metal detector for gold and silver and PI come equipped with a control box which processes signals and detects metal contaminants. Product Effect Compensation can also be done, which occurs when magnetic or conductive effects caused by ingredients, density, salt level, moisture or packaging distort the detector's field and good metal detector for beginners disrupt operation of the system. In these instances, adjusting system operating parameters is often sufficient to counteract their negative impact. Adjusting transmitter frequency or switching to higher operating voltage may be utilized to provide optimal performance. When selecting a metal detector store near me metal detector for your plant, it is essential to conduct tests under actual production conditions - preferably at its final installation location - in order to ensure it has the appropriate sensitivity settings for your products and can pick up exactly what you expect it to. By conducting such trials before final installation, you can rest easy knowing your metal detector is only picking up what it should.
