okplazas.com original authentic P+F Pepperl+Fuchs safety barrier, exquisite intrinsically safe explosion-proof, prevent it before it happens

The P+F Pepperl+Fuchs isolated safety barrier can effectively isolate the field loop signal in the hazardous area from the loop signal in the safe area. In this way, the intrinsically safe automatic control system does not need an intrinsically safe grounding system, which simplifies the construction when the intrinsically safe explosion-proof system is applied. In the related equipment of P+F Pepperl+Fuchs intrinsically safe explosion-proof instrumentation, the Pepperl+Fuchs safety barrier plays an important role in explosion protection.

P+F Pepperl+Fuchs safety barriers have been widely used in the field of safety and explosion protection. Fast fuse, current-limiting resistor or voltage-limiting diode are used in the safety barrier to limit the input electric energy, so as to ensure the energy output to the dangerous area. Its principle is simple, the circuit is easy to realize, and the price is low, but its reliability in its application is greatly affected due to its own principle defects. The isolation barrier greatly enhances the anti-interference ability of the detection and control loop, and improves the system reliability. Use isolated Pepperl+Fuchs safety barriers to allow field instruments to be grounded and allow field instruments to be non-isolated. The isolated safety barrier has many protection function circuits, and the possibility of accidental damage is small. It allows on-site instrumentation to be repaired with power, which can shorten the preparation time of the project and reduce the parking time. The P+F Pepperl+Fuchs isolation barrier also considers low power consumption in its industrial design, and its performance and technical indicators have also been improved. There are basically two types of isolated safety barriers: detection end safety barriers and operating end safety barriers. Pepperl+Fuchs safety barriers have a wide range of applications, including petroleum, chemical, coal, pharmaceuticals, highways, metallurgy, explosives plants, etc.
