Guardian SDS

The Guardian Surge Detection System (SDS) offers SIL-rated surge and overspeed protection for your rotating equipment — all in one device. Protect against damaging surge events in a safety-rated device that is independent of the control system.

The Guardian SDS incorporates all Guardian ODS overspeed detection functionality into a single unit while maintaining the capability of a TUV certified SIL-3. Compliant with API-670, API-611 and API-612 standards, the Guardian SDS integrates seamlessly with industry-leading CCC control systems — making it easier than ever to safeguard your rotating assets.
