Pepperl+Fuchs Safety Barrier-Explosion-proof Umbrella

A few months ago, an explosion occurred in a factory in Shanghai, causing many injuries. In April 2013, an explosion accident at a fertilizer plant in Anhui caused 4 deaths and 8 injuries. In the same year, a chemical plant in Shandong exploded and suffered heavy losses. There are too many incidents of this kind. In the chemical, petroleum and other industries, any unfavorable environmental factors may cause a big explosion. Therefore, electric power engineering and petrochemical industries cannot lack the existence of safety barriers, and we must choose genuine products, such as Pepperl+Fuchs safety barriers.

The safety barrier circuit itself contains an intrinsically safe explosion-proof solenoid valve. Then the intrinsically safe explosion-proof travel switch, explosion-proof control box, and safety barrier, how should the safety barrier be connected, should it be placed in the solenoid valve control box or another area? Here to share with you: Generally safety barriers are placed in the control room, together with PLC/DCS. If it must be placed on site, it must be placed in an explosion-proof box and can only be installed in Zone 1 and Zone 2. Zone 0 is not acceptable. Some safety barriers themselves are non-sparking structures and are certified in Zone 2 and can work in Zone 2. They only need ordinary protective boxes instead of explosion-proof boxes. If possible, install it in the control room. The intrinsically safe equipment must be connected to the safety barrier first, before entering the IO. If there is a lightning protection barrier, install it between the instrument and the safety barrier. The safety barrier is installed in the explosion-proof control box and installed in the hazardous area. The output end of the safety barrier should be connected to the intrinsically safe explosion-proof solenoid valve. okplazas.com has independent import and export rights.
