Functional Safety to IEC 61508 (SIL 1–3)

Sensonics delivers certified machinery protection, overspeed, vibration, and seismic monitoring systems designed in accordance with EN/IEC 61508. Our solutions help operators reduce risk, achieve compliance, and maintain high availability across power generation, nuclear, oil & gas, hydrogen, and other critical infrastructure.

Integrated Protection & Proven Reliability

Beyond condition monitoring, many Sensonics systems incorporate protective shutdown functions to safeguard machinery during excessive vibration or overspeed events. Backed by extensive field-proven data, built-in proof testing, and stated reliability levels, our integrated vibration, position, and speed protection systems are engineered to comply with IEC 61508 up to SIL 3.

Overspeed Protection Systems

Uncontrolled overspeed events can lead to catastrophic failure. Sensonics’ Sentry G3 Overspeed Protection System provides fast, independent shutdown for turbines and pumps.

Certified to IEC 61508 SIL 3, Sentry G3 supports voted architectures such as 2oo3, with response times under 20 ms and built‑in online proof testing.

Machinery Protection & Vibration Monitoring

Effective vibration monitoring provides early warning of developing faults and initiates automatic shutdown when safe limits are exceeded.

Sensonics systems support dual alarm levels, relay-based shutdown, trending, FFT analysis, and sensor integrity checks. Solutions can be engineered to meet IEC 61508 SIL 1, 2, or 3, as well as API 670 requirements.

Seismic Monitoring & Protection (SIL-Certified)

Sensonics also provides SIL-certified seismic monitoring and protection systems to safeguard critical infrastructure during earthquake and strong-motion events. Our solutions deliver reliable detection and automatic shutdown to minimise risk and protect people, plant, and assets.

Built on proven sensor technologies, redundant system architectures, and robust voting logic, Sensonics seismic systems offer high availability with minimal spurious trips. Integrated self-testing and online proof testing support stated reliability levels up to SIL 3, while enabling effective post-event analysis and regulatory compliance.
