摘要
用于过程控制部分的国际标准IEC 61511已于2003年发布,它详细叙述了安全仪表系统(SIS)生命周期里的要求。制造商已经生产出支持这一新技术的产品,可供设计者选择的传感器满足安全要求,遵从新标准,降低整个生命周期的成本。本文叙述了SIS应用中的传感器选择,符合IEC 61511标准,最小化生命周期的成本。
The international standard for safety instrumented systems for the process control sector （IEC 61511） was published in 2003 and details the lifecycle requirements for Safety Instrumented Systems （SIS）. New technologies and support from manufacturers are now available that will allow designers to select ＂sensors＂ that meet safety requirements in compliance with these new standards while reducing overall lifecycle costs. The paper outlines the selection of sensors for SIS applications that meet the requirements of IEC 61511 while minimizing lifecycle costs.
