Description

The3500/25 Enhanced Keyphasor Moduleand spare model149369-01are advanced signal processing units designed for the Bently Nevada 3500 machinery protection system. It replaces the legacy125792-01module while maintaining full form-fit-function compatibility for retrofit applications in existing racks.

The149369-01module processes input signals from proximity probes or magnetic pickups and converts them into accurate digital Keyphasor references. These signals are essential for monitoring shaft speed, phase, and vibration analysis in rotating machinery, supporting reliable predictive maintenance and diagnostics.

Engineered for flexibility, the3500/25supports single or paired configurations, enabling up to eight Keyphasor inputs in expanded systems. It is fully backward compatible and designed for industrial environments requiring high reliability, precision timing, and seamless integration with legacy monitoring platforms.

Applications

Power plants: Used for generator set monitoring, shaft speed detection, and relay protection systems.
Substations: Enables bus differential protection, switching control, and real-time signal acquisition.
Chemical plants: Supports process automation and intrinsically safe signal monitoring environments.
Steel mills (metallurgical plants): Ensures stable control under high temperature and electromagnetic interference conditions.
Machinery manufacturing plants: Applied in automated production lines, robotics systems, and packaging equipment control.
