Off the Shelf Compliance for Safety Instrumented System Design
Whether you are employing ANSI/ISA 84.00.01-2004 (IEC 61511) methods or your own “proven in use” practice for safety system design and life cycle management, Endress+Hauser can provide you the right measuring instrument and safety system support documentation you need for the cost of a standard instrument.
The elimination of separate measuring instrument versions, each dedicated to either safety or basic control, contributes to reduced life cycle costs. Endress+Hauser made the choice to provide all safety related instrumentation with a single standard class that can be used for:
- ANSI/ISA 84.00.01-2004 (IEC 61511)
- “proven in use”
- basic process control applications.
To achieve this Endress+Hauser employs the required IEC 61508 processes on all these products.
The emergence of ANSI/ISA 84.00.01-2004 (IEC 61511) and IEC 61508 standards are giving (SIS) engineers better tools to model and evaluate Safety Instrumented System (SIS) designs. Components used in safety systems are available with SIL-metrics that allow Probability of Failure on Demand Average (PFDAVG) and the Mean Time To Failure Spurious (MTTFSP) to be modeled. This goes a long way to ensure that the SIS being designed not only addresses the desired Safety Instrumented Function (SIF) and target Safety Integrity Level (SIL) but also the desired availability.
Endress+Hauser provides detailed functional safety manuals and SIL documentation that Safety Instrumented System engineers can use in their design efforts. Their standard transmitters, with their software and modification processes can support you throughout your SIS lifecycles.
