Description
Product Overview
The Bently Nevada 3500/54 133396-01 is a dual-channel speed monitoring module integral to machinery protection systems in critical industrial environments. As part of Bently Nevada’s 3500 Series, this module provides precise rotational speed measurement and overspeed protection for turbines, compressors, pumps, and other high-speed rotating equipment. The Bently Nevada 3500/54 133396-01 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.
Designed for seamless integration into 3500 racks, the Bently Nevada 3500/54 133396-01 supports dynamic speed measurement up to 50,000 RPM with ±0.1% accuracy. The module’s advanced diagnostics detect sensor health, signal integrity issues, and alignment errors, enabling predictive maintenance. With rugged construction and compliance with API 670 standards, it operates reliably in extreme temperatures (-40°C to +85°C) and high-vibration environments such as power plants, offshore platforms, and petrochemical facilities.
