What is the difference between indoor walk through metal door and outdoor metal detector door?
We know that security metal detector can be distinguished from indoor or outdoor use from IP (INGRESS PROTECTION) protection levels. The IP protection level is composed of two numbers. The first number indicates the level of dustproofing and preventing foreign objects from entering the appliance. (The foreign objects contained in this article contain tools, and human fingers are not allowed to touch the live parts of the appliance. In order to avoid electric shock), the second number indicates the degree of airtightness of the appliance against moisture and water immersion. The higher the number, the higher the degree of protection.
Therefore IP55 means: completely prevent foreign matter from invading, although it can not completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the appliance; prevent the jetted water from immersing, and prevent low-pressure water spray for at least 3 minutes.
IP65 stands for: completely prevent foreign matter and dust from entering; prevent the jetted water from immersing and prevent low-pressure water spray for at least 3 minutes. Usually Garrett and CEIA's outdoor security doors reach IP65.
The door frame material is one of the important links affecting the quality of the security door. Since the signal generated by the metal under the safe electromagnetic field environment is very small, the signal processing is usually amplified tens of thousands of times to meet the circuit drive requirements. A small displacement change, after the circuit is amplified, can cause an alarm, so it is required that the security door frame is deformed as small as possible during long-term use.
The archway metal detectors are designed as independent door frames. The sensors are equipped with thin and long shapes. The door frame thickness is only five or six centimeters (5cm-6cm) and the length is more than 220cm (220CM). Due to the installation environment and long-term working relationship, the door panel is easily deformed, so that the parameters of the sensor are too different from the factory, which affects the detection effect and cannot work for a long time.
At present, most Chinese manufacturers use wooden rafts or high-density wood fiber sheets for security door frame. It is well known that raft boards or high-density wood fiber boards are very easy to absorb moisture and damp. After a few months, they will be deformed and dispersed. Disintegration; especially in coastal areas, due to the humid air and long rainy season, the products only can be used in a short time after purchasing these metal detector doors. High-quality products or waterproof door panels, such as the shell is made of high-strength PVC material, the door frame is made of aluminum alloy, and the interior is made of multi-layer splint. It is not easy to be deformed and will not be damp, ensuring long-term normal use of the product. maintenance free in the year.
Low-cost door frame metal detector, commonly used rafters or high-density wood fiberboard, as shown:
The waterproof door panel is made of aluminum alloy and the interior is made of multi-layer flat plate, as shown in the figure:
The material difference of the main control box also determines the waterproof performance of the metal detector gate.
The main control box of indoor body metal detector is also made of high-density wood fiberboard, as shown:
The main control box of outdoor arch metal detector is made of high-quality aluminum box, which is corrosion-resistant, moisture-resistant and rust-free. as the picture shows:
