How Metal Detectors Work
Metal detectors provide public safety by enabling security officers to scan for concealed weapons and other threats. Used at events or schools, these devices help prevent harmful objects from entering and potentially injuring or damaging people or property. Unfortunately, however, these safety tools aren't foolproof and some weapon carriers know how to use them against themselves.
Many school districts have implemented measures such as clear backpack policies and school resource officers in response to gun violence in schools; however, these steps alone cannot guarantee student safety. As a result, there has been an increasing demand for preventative safety measures like metal detectors.
Metal detectors operate by detecting eddy currents within metallic objects that create electromagnetic fields when conducting electricity, which cause metal surfaces to vibrate or pulse and can be detected using an accessory called a search coil. Once detected, an object triggers a signal sending information regarding its magnetic field strength directly to electronic circuitry for analysis.
When processing this signal, it is compared to an average reading for that specific metal type. If an abnormality has been identified in its readings, an audible alert will sound to notify users.
Modern detectors come equipped with various other features, including discrimination, track speed control, threshold volume and notch filters. These metal detector machine tools enable users to fine tune their detectors for specific environments or conditions and save settings in memory for later use; some models even connect directly with smartphone applications for enhanced functionality.
Multiple companies manufacture metal detectors, with products varying greatly in terms of size, capability and price. More expensive models often contain additional bells and whistles while simpler models may be better suited for beginners. Although the technology differs among manufacturers, all modern versions utilize pulse induction sensors with digital signal processing to improve performance.
Newer models, for instance, are more resistant to mineralization and provide improved targeting, enabling them to detect objects up to 20 inches deep. Alexander Graham Bell first patented his 4-coil induction balance in 1881 but it could only detect bullets lodged in American President James Garfield's chest from two inches away; its 2-coil successor later evolved into the double D-shaped search coils used today.
Metal detectors may not be foolproof, but they are an invaluable asset when used correctly to identify individuals attempting to bring weapons into secure areas. This gives authorities time and opportunity to intervene before an incident takes place, possibly confiscating weapons, conducting further investigations or initiating lockdown procedures as needed. Metal detectors like Garrett offer invaluable support in maintaining public safety; with their strong record for technological innovation and dependability.
