P+F Pepperl+Fuchs safety barrier One-step explosion-proof safe and reliable

In many industrial processes of P+F Pepperl+Fuchs, some flammable materials need to be processed or used, such as crude oil and its derivatives, alcohol, natural gas, powder, flying materials, any leakage or splashing may create an explosive environment. The control room equipment in the safe place or the intrinsically safe equipment in the dangerous place fails. As long as the current-limiting and voltage-limiting circuit of the safety barrier works normally, the entire system will be in a safe state and will not explode.

For the safety of the factory and personnel, the P+F Pepperl+Fuchs safety barrier must ensure that the environment cannot be ignited and cause an explosion. In the production process, a large number of electrical equipment is used, and various frictional electric sparks, static sparks, high temperatures, etc. are inevitable, especially when the equipment fails, it may ignite an explosive environment. As the related equipment between the non-intrinsically safe equipment in the control room and the intrinsically safe equipment in hazardous locations, the safety barrier is an important part of the intrinsically safe explosion-proof system. Safety barriers are used alone or in conjunction with surge protectors. The control room equipment in the safe place is connected with the intrinsically safe equipment in the dangerous place through the safety barrier to transmit signals or energy. The P+F Pepperl+Fuchs safety barrier uses current-limiting and voltage-limiting circuits to limit the energy transmitted from the safe place to the dangerous place; the intrinsically safe equipment in the dangerous place can work normally under such energy, but this energy is not enough to attract In a flammable and explosive environment, even if the intrinsically safe equipment itself fails, it will not produce any sparks or heating surfaces sufficient to ignite.
