06-06-2015· Hi, In designing a metal detector with VLF technology, 1. why do we choose VLF technology as the best among other frequency e.g. HF, UHF etc. 2. What are the advantages of the VLF technology than the other frequency? Thanks.
Metal detectors generally operate on the basis of one of the following technical prin- ciples: BFO (beat frequency os- cillator). In this system, the inductor in the search head is part of an os- cillator, whose variable out- put frequency is mixed with another, fixed, frequency ob- tained from a second oscillator. The difference (beat) frequency falls within the audible range.

Our metal detectors are combined with interlocking doors to help stop armed assailants from entering facilities by denying access into a facility when a weapon is detected. When the alarm has triggered the walk through metal detector sends a signal to the system's PLC which keeps the door into the facility locked via a 1200lb pull force mag lock.
