Through metal detector gate radiation it

Security doors, also called metal detector. In the end the security gate have radiation? Is a question that people have been concerned about. Wei Antai Technology technical staff on this topic to be a brief introduction to the masses:
    Security door radiation: all electrical undeniable have radiation, the most common computer, subwoofer, electric fans, microwave ovens and other household appliances have radiation output voltage, but their output voltage is higher than some of the high security doors, radiation is very low-flying, security doors mainly by weak electromagnetic fields to work, and he was in the normal operation of the output voltage is only 12V. Therefore, the human body does not produce any harm. For pregnant women, children do not have any effects of radiation!
    How it works: the use of magnetic fields to detect changes in magnetic flux to achieve results. That is when a person with a certain amount of metal items through the security gate, brought the metal cutting magnetic field lines, so that the security gate in a uniform magnetic field changes, the flux increased, the acquisition process is greater than the set signal value, the central processor (CPU) so that the alarm system sends an alarm signal; otherwise, the security gate in a uniform magnetic field does not change, flux and there is no increase, no alarm signal.
   Security doors, mainly used to check the man metal objects hidden on the body. When inspectors from the security gate by the human body carried by the metal exceeds pre-set parameter values based on weight, quantity or shape, security doors immediate alarm, and display alarm location, allowing security personnel to detect that person contraband metal objects belt. Enterprise security, public safety essential security equipment.
