Bently Nevada 3500/53 133388-01 Overspeed Protection Module
The Bently Nevada 3500/53 133388-01 serves as a critical safeguard in industrial machinery systems, specifically designed to detect and mitigate overspeed conditions in turbines, compressors, and pumps. Engineered for environments where failure isn’t an option—think nuclear power plants or offshore oil platforms—this module ensures compliance with API 670 and 612 standards while delivering millisecond-level response times. Unlike generic protection systems, its dual-channel architecture supports both 2-out-of-2 and 2-out-of-3 voting configurations, making it a cornerstone of redundant safety systems.

In real-world applications, this module shines where downtime carries extreme costs. A power plant engineer recently shared how the 3500/53 detected a turbine overspeed event during a grid failure, preventing a $2M+ repair incident. The device integrates seamlessly with Bently Nevada’s 3500 rack systems and works alongside proximity probes like the 3500/15 and 3500/42M. We’ve seen it deployed in:
- Gas turbine installations in Middle Eastern oil fields
- Steam turbine protection systems in European nuclear plants
- Marine propulsion systems on LNG carriers
