okplazas.com German original Pepperl+Fuchs safety barriers spring hot sale in progress

The P+F Pepperl+Fuchs safety barrier is mainly used for on-site explosion-proof, such as the petroleum, chemical, metallurgical and other industries that exist to a certain degree of danger. The safety barrier can be equipped with a good protection for the production site. For example, in the power distribution room of the metallurgical industry, the detection end is powered by the safety barrier of the safety barrier to the on-site transmitter in the dangerous area, and each transmitter is provided with an independent isolated power supply, and the power input and output are isolated from each other.

Pepperl+Fuchs Safety Barrier

The instrument connection of Pepperl+Fuchs metallurgical industry in explosion-proof occasions forms an intrinsically safe circuit through a safety barrier and intrinsically safe instrument, which plays the role of intrinsically safe explosion-proof. At the time of purchase, please note that the selected Zener safety barrier should have been certified by the explosion-proof inspection agency and have an explosion-proof qualification certificate. The associated equipment of Pepperl+Fuchs intrinsically safe explosion-proof instrumentation does not affect the function of the measurement system under normal conditions. The Pepperl+Fuchs safety barrier is installed on one side of the safe place. When the intrinsically safe explosion-proof system fails, it can limit the energy entering the dangerous place within a safe value, thus ensuring the safety of on-site production. Almost without exception, isolation safety barriers are used as the main intrinsically safe explosion-proof instruments in high-demand engineering sites. Isolated safety barriers have gradually replaced Zener safety barriers and have been increasingly used in the field of safety and explosion protection. Its principle is simple, the circuit is easy to realize, and the price is low. However, due to its own principle defects, its reliability in its application is greatly affected and its application range is limited.
