3. Function and Product Positioning

Core Functions

• High-Fidelity Transient Data Capture: Simultaneously acquires high-resolution waveform data (vibration, displacement, speed) from all 3500 monitor modules during steady-state and transient events (startup/shutdown, load changes, faults).

• Data Synchronization & Processing: Time-synchronizes data across all channels; processes raw signals into engineering units (mm/s, μm, g); supports Bode, Polar, and Cascade plot generation for rotor dynamics analysis.

• Dual Communication Interfaces:

  • Ethernet: Transmits real-time and historical data to System 1 software for remote monitoring, trending, and diagnostics.

  • USB-B: Provides local, plug-and-play access for on-site configuration, data logging, and troubleshooting without network connectivity.

• Rack Management: Acts as the interface between the 3500 rack and external systems; supports rack configuration, firmware updates, and health status reporting.

• Event Logging: Captures and stores up to 10,000 critical events (alarms, trips, sensor faults, speed changes) with time stamps for root-cause analysis.

Operational Features

• Seamless Software Integration: Fully compatible with Bently Nevada System 1 (v8.0+) and 3500 Configuration Software for end-to-end monitoring and setup.

• Hot-Swappable: Can be replaced or inserted into the 3500 rack without powering down the system, minimizing maintenance downtime.

• Fault Tolerance: Built-in diagnostics for module, backplane, and communication faults; reports status via front-panel LEDs and System 1 software.

• Signal Optimization: Performs advanced signal conditioning for proximity probes, ensuring high-accuracy displacement data for shaft position and vibration monitoring.

Product Positioning

• Critical rotating equipment (turbines, compressors, generators) in power generation, oil and gas, and petrochemical industries.

• API 670-compliant machinery protection and condition monitoring requiring high-resolution transient data for fault diagnosis.

• Integration with System 1 software for predictive maintenance, asset health management, and compliance reporting.

• Retrofit projects upgrading older 3500 racks to support modern diagnostic software and high-speed data acquisition.
