Bently Nevada 125800-01 is an advanced Enhanced Keyphasor Module engineered for the 3500 Series Machinery Protection System. Designed as a half-height, dual-channel unit, it receives signals from proximity probes or magnetic pickups and converts them into precise digital timing pulses for shaft speed, phase reference, and vibration analysis. It is widely used in rotating equipment diagnostics where reliable synchronization data is essential.
Built for demanding industrial environments, 125800-01 improves signal processing performance while remaining fully compatible with earlier Bently Nevada 3500/25 modules. It supports once-per-turn and multiple-event-per-turn inputs, enabling accurate monitoring of turbines, compressors, motors, and pumps across different speed ranges.
With dependable communication, field-upgradeable firmware, and seamless integration with models such as 149369-01 and other 3500 Series components, 125800-01 offers a practical upgrade path for modern condition monitoring systems.
