安全完整性等级 (SIL) 分析及应用Safety Integrity Level (SIL) Analysis and Applications 【摘要】:过程工业涉及的领域广、危险性大,工厂除了在工艺设计阶段尽可能的考虑防止和减少各种潜在风险外,还必须附加额外的保护措施来控制危险的发生,如安全仪表系统(SIS)
本文结合实际例子介绍了 SIS 系统安全完整性等级(SIL)的应用,并对不同等级下 SIS 系统的硬件组成要求做了探讨
Abstract: Process industry is involved a wide area of enterprises and hazardous, the factory shall try best to prevent and reduce potential risk at process design stage, besides other protective measures like safety instrument system (SIS) also shall be used to control occurrence of dangerous accidents
This paper has introduced basic theory of SIL level for SIS system, and also discussed SIS hardware requirement for different SIL levels
