What should you pay attention to when buying an explosion-proof mobile phone?
With the progress of scientific and technological development and the development of industrial intelligence, the application of data sharing has become more and more extensive, and data sharing has also become the guarantee of enterprise security. As the main supplier of energy such as kerosene, gasoline, diesel and natural gas, the petrochemical industry is also in a dangerous place. Ordinary smart phones cannot meet the requirements of operation in hazardous areas, so a professional industrial explosion-proof mobile phone is required.
Because explosive mixtures commonly exist in the production, processing, storage and transportation of coal, petroleum, chemical, textile, grain processing and other industries, ordinary mobile phones have become a strong source of safety accidents in these places, and if an explosion occurs, it will be very harmful. Explosion-proof mobile phones fundamentally solve the problem of ignition sources. Manufacturers have adopted a variety of explosion-proof technologies, such as intrinsically safe circuits, limiting casing, surface temperature, and using "dust-tight" or "dust-proof" casings to limit dust entry, etc. Prevent the explosive mixture from being ignited, so that the explosion-proof mobile phone can be used safely in the above-mentioned hazardous environment.
So what should you pay attention to when purchasing an explosion-proof mobile phone?
Explosion-proof signs of explosion-proof mobile phones:
For explosion-proof mobile phones, the explosion-proof certification level issued by the explosion-proof electrical product quality supervision and inspection center is an important indicator. The grades are divided into ABC three grades, C grade is the high grade. From the detonating substances are divided into two kinds of gas and dust. The temperature of these flammable and explosive substances is also a very important factor. The Quality Supervision Center divides the temperature into 6 grades, from T1 to T6. The higher the temperature, the safer it is.
Anti-counterfeiting signs of explosion-proof mobile phones:
When choosing an explosion-proof mobile phone, pay attention to whether anti-counterfeiting signs, explosion-proof signs, and mobile phone serial numbers can be found.
Warranty period of explosion-proof mobile phone:
When choosing an explosion-proof mobile phone, you should ask how long it is guaranteed for the mobile phone (usually 1 year). If the warranty is not included, it is recommended not to buy it.
