Archway Walk Through Metal Detector Gate

What is a walk through metal detector? Walk-through metal detectors utilize magnetic fields to detect metal that passes through them. The science behind how they work is based on Maxwell's equations. The latest detectors include multiple detection zones allowing them to pinpoint the location of the metal causing the alarm. How do metal detector doors work? The pulse generates a short magnetic field. When a piece of metal crosses through this magnetic field, a reflected magnetic field will emerge and this magnetic field will react with the receiver coil, which initiates the alarm in the door frame metal detector. This process will happen in a few microseconds. How deep can metal detectors detect? Most metal detectors can detect objects about 4-8ʺ (10 - 20 cm) deep. In ideal conditions, a mid-range metal detector can reach 12-18ʺ (30-45 cm) underground. Some specialized detectors can go as deep as 65' (20 m) What metals cannot be detected by a metal detector? Metal detectors have a tough time detecting metals like stainless steel, which have very poor electrical conductivity. Stainless steel has low magnetic permeability, which means it does not produce a signal strong enough to be detected. Other items that metal detectors won't be able to locate include: Gemstones How much does a walk through metal detector cost? A stationary metal detector can cost anywhere from BDT 50,000 to BDT 3, 50,000. Best range typically offer features best suited for a school environment, according to a report from the National Institute of Justice Related video: Digital Signage Display Kiosk Bangladesh:    • Digital Signage Display Kiosk Bangladesh   Swing Barrier Gates in Bangladesh:    • Swing Barrier Gates in Bangladesh   Tripod turnstile gate in Bangladesh:    • tripod turnstile gate  in Bangladesh   IP CCTV Camera For Home Security Surveillance in Bangladesh:    • IP CCTV Camera For Home Security Surveilla...   Follow our Social Media: Facebook:   / gctlbd   Instagram:   / gctl_security   LinkedIn:   / gctlbd   Pinterest:   / _saved   Google my Business: https://business.google.com/u/1/dashb... #metal_detector_gate #walk_through_metal_detector #archway_metal_detector_gate #Archway_Walk_Through_Metal_Detector_Gate Video credit: Dahua Walk-through Metal Detector
