The security gate is a device used to detect the presence or absence of metal objects. It is also known as a metal detection gate. It is mainly used in airports, stations, and other traffic places with high traffic. The purchase of security gates has always been a problem for consumers. The following editors will detail the four main points of security gate purchases.
Four key points to purchase at security gate
1. High-level security check function
The demand for metal detection gates with high security inspection requirements includes the following factors:
â‘´ The uniformity of the magnetic field is the key to 100% detection rate;
⑵, security inspection and search power must be sufficient to detect any hazardous metal objects, regardless of their entry position and angle;
(3) The security inspection and search power must be sufficient to detect personnel passing through at any speed;
â‘· Must have the ability to detect ferrous and non-ferrous metals simultaneously.
â’‰High level of recognition
It is required to be able to distinguish a small amount of hazardous metal objects (such as small arms) from various metal substances carried by individuals.
Resolving power is based on the following factors:
â‘´, the uniformity of the magnetic field distribution;
⑵, various analytical capabilities of metal substances;
⑶, immunity to external motor noise interference;
â‘·, immunity to external mechanical interference;
â’ŠGood (noise interference) immunity
Noise interference is an important reason that affects the performance of metal detection doors. The noise interference is divided into the following types:
(1) Transient noise: the noise generated by the co-loading of the motor, electric control lock, and power supply line;
⑵, intermittent noise: radio frequency noise generated by the power supply equipment on the voltage;
(3) Noise generated by other nearby metal detectors;
â‘·, noise caused by moving or vibrating metal quality.
â’‹ Equipment proper rate
To consider the proper rate of equipment, you can observe from two points:
(1) Whether to use SMD technology to assemble the electronic substrate;
(2) Whether the control panel host is tested for function.
The above is the introduction of the four main points about the purchase of security gates. I hope you can correctly buy your favorite products according to these four main points. I wish you a happy purchase.
High Velocity Powder-Actuated Tool is used for normal concrete not harder than C40. The nail initial velocity is very high as there is no piston but high pressure gas to push it.
Powder-actuated tools come in high-velocity and low-velocity types. In high-velocity tools, the propellant charge acts directly on the fastener in a process similar to a firearm. ... Powder-actuated fasteners are made of special heat-treated steel. Common nails are not used for powder-actuated fastenings.
