The alarm detector is very obvious. Knowing its name, it knows its purpose. Its role is to detect intrusions. It is composed of sensors and signal processing. It is used to detect intruder intrusions and is the first line of defense for burglar alarm systems. Because the illegal intrusion is first detected by the detector, the alarm can be sent out. If there is no signal from the detector to the anti-theft alarm, the alarm will not alarm. The sensor is the core element of the alarm detector. The sensor components with different principles can be used to construct different types of alarm detectors with different purposes and different detection purposes.
(1) Alarm detectors can be divided into infrared alarm detectors, microwave alarm detectors, passive infrared/microwave alarm detectors, glass broken alarm detectors, vibration alarm detectors, ultrasonic alarm detectors, laser alarm detection according to the working principle. , magnetic switch alarm detectors, switch alarm detectors, video motion detection alarms, sound detectors and many other types. These detectors are installed at the forefront of the anti-theft alarm system to detect various intrusions and ensure that they can be detected as long as there are illegal intrusions.
(2) Alarm detectors can be classified into active alarm detectors and passive alarm detectors according to their working methods. The active detector adopts an active method, and the detector actively detects the intrusion. Passive detectors use a passive method, in which the intruder actively enters the detection range.
(3) Alarm detectors can be classified into point-controlled alarm detectors, line-controlled alarm detectors, surface-controlled alarm detectors, and space-prevention alarm detectors according to different detection ranges.
The burglar alarm serves as the main equipment for modern security and is used to report intruder intrusions and various abnormal conditions. There are many places where security precautions are required in various smart buildings and ordinary buildings. With the development of intelligent buildings and intelligent security, the use of anti-theft alarms has become more and more, as anti-theft alarm manufacturers do not immerse in a beautiful environment, because the market demand is now more and more manufacturers of anti-theft alarms More, so the market competition is getting bigger and bigger. Therefore, security manufacturers need to develop a variety of alarm detectors and alarms to meet different security requirements.
coupling magnet:
Connects motor, consists of external rotor, internal rotor and isolating cover, both inner and outer rotors are fitted with permanent magnets in a multi-pole arrangement and are moved synchronously so as to achieve non-contact power transmission . May transport volatile, flammable, explosive and toxic air or liquids without leakage.
We may design with Maximum working torque with fewer magnets, minimum sizes to lower cost while achieving a given torque.
