Bently Nevada 3500/33 149986-01 Dual Voting Trip Module – 3500 Series Machinery Protection System
Imagine a critical rotating machine — a high-speed compressor, a steam turbine, or a boiler feed pump — running at full load in your plant. Without a functioning trip module, the machinery protection system loses its ability to execute a safe, coordinated shutdown when vibration or process parameters exceed safe limits. The result: uncontrolled mechanical failure, catastrophic downtime, and potentially irreversible damage to assets worth millions. The Bently Nevada 3500/33 149986-01 Dual Voting Trip Module is the last line of defense between normal operation and disaster — it is not a component you can afford to substitute or leave unverified.
Within the Bently Nevada 3500 Series Machinery Protection System — the global industry benchmark for continuous machinery monitoring — the 3500/33 occupies a mission-critical position. It receives relay outputs from monitoring modules and executes dual-voting logic to determine whether a trip condition is genuine, eliminating spurious shutdowns while ensuring no real fault goes undetected. Deployed across refineries, LNG terminals, power generation facilities, and petrochemical plants on every continent, the 3500 Series and its 3500/33 trip module represent the standard against which all other machinery protection platforms are measured.
