安全仪表系统(Safety instrumented systems,SIS)是一种自动安全保护系统,它是保证正
常生产和人身、设备安全的必不可少的措施,它已发展成为工业自动化的重要组成部分。在过程工
业中,安全仪表系统的安全性对于事故的影响十分巨大,由于过程工业中的安全事故通常会造成人
员伤亡和巨额财产损失,因此开展过程工业安全仪表系统安全评定对于确保过程工业安全具有重要
意义。统计资料表明,过程工业中,由于对安全仪表系统的安全要求不合理以及投产后的项目改造过
程中对安全仪表系统的改建不恰当所造成的安全事故在全部事故中所占的比重最大。安全仪表系统
设计不当,一种可能的后果是该跳车时不跳,造成拒动作;另一种可能的后果是不该跳车时跳车,造成
误动作。拒动作会造成严重甚至灾难性的后果,误动作的直接后果是装置停车,造成巨额的经济损失。
