The P+F Pepperl+Fuchs safety barrier intrinsically safe system has attracted more and more attention in Asia, and the safety barrier as its main component is also known by people. Pepperl+Fuchs safety barriers are divided into Zener barriers and isolation barriers. The explosion-proof principle of the Zener grid is to use a Zener diode to control the output voltage and a resistor to limit the output current. The circuit is relatively simple. When the production industry is working normally, the isolation barrier is equivalent to two resistors in series into the circuit, so there is no need to change the system structure.
Pepperl+Fuchs Safety Barrier
As a field explosion-proof product, the safety must be strict. When using, the installation location must have a very reliable grounding system, and the grounding resistance of the Zener safety barrier must be less than 1Ω, otherwise the explosion-proof safety protection performance will be lost. Obviously Such requirements are very harsh and difficult to guarantee in actual engineering applications. China has strict and scientific regulations on intrinsically safe safety barriers. Only the enterprises that have passed the certification of the supervision station and the products they develop and produce can have the safety performance that meets the standards. The P+F Pepperl+Fuchs safety barrier uses high frequency as the fundamental wave to modulate and demodulate the signal. If the signal changes, the accuracy will be affected by the safety barrier circuit. Due to the high frequency oscillating circuit of the isolation safety barrier, radio frequency interference will be generated, which is detrimental to the system, and the isolation safety barrier is also relatively easy to damage. Secondly, it is required that the field instruments from the dangerous area must be isolated, otherwise the signal cannot be transmitted correctly, and the signal is grounded, which directly reduces the signal anti-interference ability and affects the system stability. okplazas.com's independent storage warehouses provide original and authentic Pepperl+Fuchs safety barriers for spot and futures.
