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.

Remote initiation of proof test

  • Regular verification or remote iterative proof test with SIL certified protocol (hardware/ software)

Safety by choice

Our extensive SIL qualified and certified instrumentation portfolio is developed according to IEC 61508. We offer the best solutions for every measuring task including flow, level, pressure, temperature and measurement subsystems. Many of our devices have a SIL rating of SIL 2/3. This means you can reach SIL 3 even in homogeneous redundancy.

Safety by smart proof testing

Sensors and sensor subsystems must be proof tested to ensure that they are available to carry out their safety role. With smart sensors you are able to evoke proof testing procedures including in-situ proof testing via a push-button or software simulation. Actionable diagnostics and safety parameters offer you the ability to extend proof test intervals reducing your risk, lowering costs and improving availability.
