Product Overview
The Bently Nevada 3500/54 133396-01 is a dual-channel speed monitoring module critical to machinery protection systems in critical industrial environments. As part of the Bently Nevada 3500 series, it provides precise rotational speed measurement and overspeed protection for turbines, compressors, pumps, and other high-speed rotating equipment. It processes signals from proximity probes, magnetic pickups, or tachometers, delivering real-time speed data and triggering alarms or shutdowns to prevent catastrophic failures. Its dual-channel redundancy ensures continuous operation even during sensor or channel faults, aligning with SIL 2 safety standards (IEC 61508/61511) for critical applications.
