因为屏蔽体对来自导线、电缆、元部件、电路或系统等外部的干扰电磁波和内部电磁波均起着吸收能量（涡流损耗）、反射能量（电磁波在屏蔽体上的界面反射）和抵消能量（电磁感应在屏蔽层上产生反向电磁场，可抵消部分干扰电磁波）的作用，所以屏蔽体具有减弱干扰的功能。
屏蔽体材料选择的原则是：
（1）当干扰电磁场的频率较高时，利用低电阻率的金属材料中产生的涡流，形成对外来电磁波的抵消作用，从而达到屏蔽的效果。
（2）当干扰电磁波的频率较低时，要采用高导磁率的材料，从而使磁力线限制在屏蔽体内部，防止扩散到屏蔽的空间去。
（3）在某些场合下，如果要求对高频和低频电磁场都具有良好的屏蔽效果时，往往采用不同的金属材料组成多层屏蔽体。来电咨询：郑娟萍（小妹）++工作QQ ：3150816822

Triconex的版本9-10系统
TRICONEX 安全控制系统是基于三重模件冗余 (TMR) 结构的最先进的容错控制器。 TMR 是集成了三路隔离的、并行工作的控制系统，并在每一个独立的控制系统中执行广泛的诊断。系统采用三取二逻辑表决方式，提供高度完善、无差错、不间断的过程操作，不会因为单点的故障而导致系统失效。
TRICONEX 系统最大的特点是能同时满足高可靠性、高可用性的容错控制能力。为保证系统的高可靠性和高可用性，控制器、I/O 模块 、通讯均采用三重化设计。控制系统可以识别控制系统元件的故障，自动把故障的元件加以排除，并允许在继续完成指定任务的同时，对故障元件进行在线修复而不中断过程的操作。任何故障及相关数据被存储在 NVRAM 中，在 I/O 模块中任一通道故障，系统保证该模块能维持运行 1500 小时，仍能满足 TUV AK6 级。Square D Enclosed 225 Amp Circuit Breaker With Q2L3225
