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.
