    Simplifying Safety Valve Proof Testing

    A safety instrumented function (SIF) within a safety instrumented system (SIS) consists of a sensor, logic solver, and final element. As part of the IEC 61511 global safety standard, these elements within the SIF must be tested during the operational phase of the safety lifecycle. Of the 3 elements, the final control element, typically a safety valve, has mechanical movement which must be tested. In a Processing magazine...
