Do some **not require a safety barrier? In China, safety barriers of the MTL and P+F brands are commonly used.

Why not use a safety barrier in some cases? Safety barriers are widely used in China, with MTL and P+F being the popular brands. It is necessary to use them in many situations. As far as I know, the areas in China where safety barriers are currently used mainly include North China and Northwest China. Does anyone know more about the specific regions where they are utilized?
This topic is quite interesting. Safety barriers are primarily used in intrinsically safe circuits. Intrinsically safety is a type of explosion-proof protection method, and due to its characteristics it is mainly applied in instrument sensors. The related industries include petroleum and natural gas, various chemical industries, thermal power generation, and the pharmaceutical industry. I’m not sure how the information mentioned by the original poster was compiled; it can only be said that currently, these industries in China are likely mainly located in North China and the Northwest region I am in Jiangsu, and given the current situation there, there are also many chemical enterprises along both banks of the Yangtze River below Nanjing. As for those that **do not require safety barriers, it is likely that these** industries with high pollution levels have moved to other places, such as China.
In recent years, environmental protection measures have been tightened in China; it is expected that the market for safety barriers will be limited. Nevertheless, they remain an essential component. Going forward, China will also relocate certain industries to nearby, stable areas.

Regarding the explosion-proof performance of intrinsically safe systems, either safety barriers for power supply or intrinsically safe voltage regulators can be used. In terms of electrical performance, safety barriers suffer from a significant voltage drop, and the zener barriers have strict requirements regarding grounding; meanwhile, isolation barriers experience a precision loss of around 0.1%. . . Therefore, a popular method is not necessarily the best approach; it might even be a rather poor one. . . I prefer the Benwan regulated power supply. It’s easy to use and control. It’s quite easy to use, though .......... :lol
The design concept truly needs comments from industry experts; just passing by...
