Induction metal detector metal detectors and door sensors can be used with automatic door system at the same time use the metal detector to the signal output signal to open or close automatic door sensor systems, driving automatic doors to open or close the action.
Metal detector principle is: the a sense space and generate clutter field, it will have amplified signal, if not of metal, even if no signal is made worse.
Also one, it send a frequency electromagnetic waves, because the metal has self-inductance, will shift the frequency of occurrence, when it followed a deviation of electromagnetic waves received, assemble the difference frequency amplified policy.
Metal detector in the detection sensor to detect when the doorway area to be in the metal signal an alarm sound. Principle of distinction by function follows:
1, the metal detector gate accuracy: maximum agility in the center of the threshold can be detected through pin (or 1 / 2), paper clip, could be detected using a hundred times a great deal of times, and the string won't be omitted reported. Can also be eliminated belt buckle, shoes, bra impact test to 150 grams of copper, aluminum, zinc different metal, or knives.
2, the metal detector gate six location display: Products are divided into six zones, each zone suspicious objects can show up properly.
3, variety of metal detector gate statistics: cash advances and could be detected via alarm number, take the 100 meter 100, not or less about prepare.
4, the metal detector gate shock-proof design: globe exclusive shock-proof design, browsing the core of the door, slapped both sides of the door, the should not false possible benefits.
5, adjust the metal detector gate agility: agility can be adjusted, an utter of two hundred dollars agility.
6, the metal detector gate door material: type of utilize of of PVC, and foreign brands among the same material and appearance, beautiful, generous, fire and moisture.
7, the metal detector gate post lights on sides: they can be kept are two rows of LED lights, a visual display of your alarm location, sound and light-weight alarm on the other hand.
8, metal detector door panel display: The front panel live view screen (LCD) means that in the English menu, built-in agility to detect a number of places recommended to set the value, one-touch buttons, like electronics factory use, select electronics factory, all the its parameter is the electronic factory parameters, more simple to install and suppress.
