The safety barrier can achieve the purpose of not generating electric sparks or temperature rise by limiting the voltage, so as to achieve explosion-proof. Pepperl+Fuchs safety barriers are used for instrumentation and are usually installed in the control cabinet together with the control system. Safety barriers are mainly used in petroleum, chemical, petrochemical, natural gas, medicine and other industrial fields where there are flammable and explosive dangerous places.

Pepperl+Fuchs Safety Barrier

When the isolation barrier is individually energized and debugged, you must pay attention to the type, power polarity, voltage level of the isolation barrier, and the label on the terminal of the isolation barrier. Pepperl+Fuchs safety barrier is an energy-limiting interface between field equipment and control room equipment. Therefore, regardless of whether the control room equipment is in a normal or faulty state, the safety barrier can ensure that the energy transmitted to the field equipment through it is intrinsically safe. Make sure that this environment will not be ignited. When the isolation barrier is individually energized and debugged, you must pay attention to the type, power polarity, voltage level of the isolation barrier, and the label on the terminal of the isolation barrier. The basic principle of intrinsic safety is very simple. All flammable materials are grouped according to the amount of energy required to ignite them. Safety barriers are very important industrial explosion-proof products. Pepperl+fuchs safety barriers are related equipment of intrinsically safe explosion-proof instrumentation. Under normal circumstances, it does not affect the function of the measurement system and is set in a safe place. When the intrinsically safe explosion-proof system fails, the energy (electric energy) entering the dangerous place can be limited to a safe value, thereby ensuring the safety of on-site production.
