安全屏障

本质安全屏障用于与某些批准用于危险区域的变送器进行通信并提供隔离。 障碍物限制了进入危险区域的能量的传递，从而阻止了在易燃气体中的着火。
Intrinsically Safe Barriers are used to communicate with certain transmitters approved for use in hazardous areas and to provide isolation. Barriers limit the amount of energy allowed to pass into the hazardous area, which inhibit ignition in flammable atmospheres.
