Configurable Outputs

User-selectable 1 PPR or 60 PPR pulse outputs allow integration with external data loggers, PLCs, or diagnostic tools, supporting diverse monitoring and control requirements.

Robust Signal Processing

Advanced filtering and noise rejection capabilities ensure reliable signal detection even in electrically noisy industrial environments, minimizing false speed readings.

Seamless 3500 Integration

Connects to the 3500 system backplane to share speed and timing data with vibration monitors, enabling synchronized data collection for comprehensive machinery health analysis.

Function

The primary function of the 3500/05-01-02-00-00-01 is to monitor rotational speed and provide timing references for the Bently Nevada 3500 Machinery Protection System. It receives Keyphasor signals from magnetic pickups mounted on rotating shafts, processes the signals to calculate speed and generate timing pulses, and synchronizes vibration data collection across the 3500 system. This synchronization allows for precise phase analysis of vibration signals, enabling accurate identification of rotational faults such as unbalance, misalignment, and shaft bow. The module also outputs speed data to external systems, supporting real-time monitoring and control of rotating machinery.

Use

In industrial settings, the module is installed in the 3500 system rack, connected to magnetic pickups on rotating equipment such as turbines, compressors, and motors. It continuously monitors rotational speed, providing timing signals to vibration monitors for synchronized data collection. Operators use its speed data to assess machinery performance, while maintenance teams leverage phase-synchronized vibration analysis to diagnose rotational faults. Its configurable outputs integrate with control systems to trigger alarms or adjust operations based on speed fluctuations, ensuring safe and efficient machinery operation.

Application Fields

Power Generation

In coal, gas, and nuclear power plants, it monitors turbine and generator rotational speed, enabling synchronized vibration analysis to detect unbalance or misalignment, critical for reliable electricity production.

Oil and Gas

Monitors compressors, pumps, and gas turbines in upstream, midstream, and downstream operations, providing speed data to optimize performance and diagnose rotational faults in harsh energy environments.

Chemical Processing

Supports speed monitoring of mixers, agitators, and centrifuges, ensuring precise rotational control and enabling early detection of faults that could disrupt chemical production processes.

Pulp and Paper

Monitors paper machine rollers and motor rotational speed, synchronizing vibration data to identify misalignment or balance issues that affect product quality and production efficiency.

Metals and Mining

Tracks speed of crushers, conveyor motors, and mill drives, providing critical data to prevent equipment overload and diagnose rotational faults in rugged mining environments.

In summary, the Bently Nevada 3500/05-01-02-00-00-01 is a vital Keyphasor module that enhances the 3500 system’s ability to monitor and protect rotating machinery.
