Functional Safety (SIL)

Functional Safety for Process Instrumentation and Analytics

Since the IEC 61508 and IEC 61511 standards for functional safety came into effect, demand has increased for process instrumentation and analytics devices conforming to the Safety Integrity Level (SIL) classification. You can find all the important information about our SIL-related products here: Deliverable Products, Manufacturer Certificates, Safety Manuals and additional information brochures and links for the topic of Functional Safety.
