okplazas.com Pepperl+Fuchs safety barrier is intrinsically safe and explosion-proof, giving you peace of mind and peace of mind

Users of cutting-edge products in the safety barrier industry can choose suitable product types and product models according to different use environments to ensure the normal operation of the safety barrier system. It is necessary to determine the parameters of the safety barrier according to the system parameters. Zener safety barriers mainly Working voltage, maximum working voltage, terminal resistance and other parameters, Pepperl+Fuchs isolation safety barrier mainly depends on the achievable accuracy.

Pepperl+Fuchs Safety Barrier

Pepperl+Fuchs safety barriers work environment, such as operating temperature, humidity, and whether the installation method is convenient for on-site installation, etc., suitable for petrochemical, coal, oil refining, explosion-proof and flammable occasions. It is strictly prohibited to use a megohmmeter to test the insulation between the safety barrier terminals. If you want to check the insulation of the system circuit, you should disconnect all the isolated safety barrier wiring first, otherwise it will cause damage to the internal components. Pepperl+Fuchs safety barrier has two types: Zener barrier and isolation barrier: Zener barrier, whose main component is a Zener tube, also called a Zener diode. But the Zener diode can only control the voltage value, so what element controls the current that constitutes the second element of electrical energy? Resistor, a resistor with a certain power bearing capacity here acts as a current limiting function, so that the current from the safety barrier to the dangerous area is always controlled within an allowable range, thereby achieving intrinsic safety. Pepperl+Fuchs isolation barrier does not require intrinsically safe grounding, which is an advantage over Zener barriers. The difference between intrinsic safety and explosion-proof is that the intrinsic safety of the equipment material and circuit is required, and the explosion-proof is through the shell and additives. Intrinsically safe type is intrinsically safe, and explosion-proof type is required for explosion-proof performance.
