okplazas.com Pepperl+Fuchs safety barrier is stable and safe, and the workers are very relaxed

Safety barrier is one of the indispensable products in metallurgy, chemical industry, petroleum, water treatment, electric power, cement production and other industries. Pepperl+Fuchs safety barriers use fast fuses, current-limiting resistors or voltage-limiting diodes to limit the input electrical energy, so as to ensure the energy output to the hazardous 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.

Pepperl+Fuchs Safety Barrier

The safety barrier is an important part of the intrinsically safe system. Pepperl+Fuchs safety barriers mainly include Zener safety barriers and isolation safety barriers. The core components of Zener safety barriers are Zener diodes, current-limiting resistors and fast-fuse wires. The isolated safety barrier has not only limited energy function, but also isolation function. It is mainly composed of loop energy limited unit, signal and power isolation unit, and signal processing unit. The isolation barrier in the safety barrier is one of the more commonly used explosion protection products. The isolation barrier effectively isolates the on-site 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 require an intrinsically safe grounding system, which simplifies the construction when the intrinsically safe explosion-proof system is applied. The isolation barrier greatly enhances the anti-interference ability of the detection and control loop, and improves the reliability of the system. Use isolated P+F safety barriers, allow field instruments to be grounded, and allow field instruments to be non-isolated. The isolated safety barrier has many protective function circuits, and the possibility of accidental damage is small. On-site instrumentation is allowed to be overhauled with power, which can shorten the preparation time of the project and reduce the parking time. Isolated safety barriers have strong signal processing capabilities. In the industrial industry, Pepperl+Fuchs series products include encoders, sensors, proximity switches, photoelectric switches, ultrasonic sensors and other products in addition to safety barriers. In addition, there are well-known industrial control brand products such as MTL, Koyo, Phoenix, and Shike.
