Product function

High-Speed Monitoring: Continuously measures shaft speed via proximity probes or encoders using Bently Nevada 286566-01.

Hardware Trip Logic: Compares measured speed against two independent thresholds and actuates hardwired relay outputs for instantaneous turbine shutdown.

Redundancy & Voting: Optional dual-module or dual-channel voting configurations with Bently Nevada 286566-01 provide fail-safe protection.

Application Areas

Steam & Gas Turbines: Primary overspeed protection via Bently Nevada 286566-01 to prevent rotor burst.

Compressors & Pumps: High-speed machinery requiring immediate shutdown.

Generators & Turbo-Generators: Safeguarding against uncontrolled overspeed.

Marine & Aerospace Test Stands: Critical overspeed detection for safety.
