Pepperl+fuchs safety barriers do the best explosion-proof work for you

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

P+F Pepperl+Fuchs metallurgical industry's instrument connection for 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 intrinsically safe explosion-proof instrumentation does not affect the function of the measurement system under normal conditions. It is set 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, so as to ensure 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 widely used in the field of safety and explosion protection. Fast fuses, current-limiting resistors or voltage-limiting diodes are used in the circuit 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. However, due to its own principle defects, its reliability in its application is greatly affected and its application range is limited.
