Functional safety SIL

The production of a safety instrumented system must be done with the best SIL certified instruments

To obtain reliable information for safety instrumented systems (IEC 61511), proper instrument specification and implementation is crucial. The application must be clear, the correct instrument technology applied and the life cycle properly managed.

Functional safety in process instrumentation. Learn about Safety Integrity Levels (SIL), continuous self-monitoring, homogeneous redundancy and proof testing.

    Functional Safety in practice

    Investments in functional safety, and thus in measures to avoid accidental and systematic errors, are very moderate if one relies on instruments developed according to IEC 61508.
