Key Features

1. Multi-Parameter Vibration Monitoring
   • Monitors shaft vibration, eccentricity, differential expansion, and axial position with 14-channel high-speed data acquisition.
   • Compatible with Bently Nevada and other industry-standard vibration sensors for rotating machinery.
2. High-Accuracy Signal Processing
   • 16-bit ADC and 4,600 samples/sec sampling rate deliver precise vibration amplitude, frequency, and phase data.
   • Advanced filtering conditions raw sensor signals to eliminate EMI/noise in harsh industrial environments.
3. Seamless Mark VI Integration
   • 6U VME form factor fits standard Mark VI control cabinets; connects to TVIB/DVIB terminal boards for sensor interfacing.
   • Transmits digitized vibration data to the Mark VI controller via the VME bus for real-time analysis and protection actions.
4. Robust Industrial Reliability
   • Wide operating temperature range (-40°C to +85°C) and ruggedized components withstand extreme power plant conditions.
   • On-board diagnostics and LED indicators enable real-time status monitoring and fault troubleshooting.
5. Predictive Maintenance & Protection
   • Detects early anomalies (imbalance, bearing wear, misalignment) to prevent catastrophic turbine failure.
   • Supports data logging and remote monitoring via Mark VI HMI/software for trend analysis and proactive maintenance.

Application Scenarios

• Power Generation (Core Application)
  • Gas Turbines: Monitors shaft vibration and balance in combined-cycle power plants, ensuring safe startup, load operation, and overspeed protection.
  • Steam Turbines: Tracks eccentricity, differential expansion, and bearing vibration in thermal power stations to avoid thermal stress and mechanical damage.
  • Hydro Turbines: Measures runner shaft vibration and axial displacement in hydroelectric plants for stable power generation.
• Process Industries
  • Oil & Gas: Monitors turbine-driven compressors/pumps in refineries, pipelines, and LNG facilities, preventing unplanned downtime.
  • Chemical & Petrochemical: Protects turbine-driven reactors, blowers, and rotating equipment from vibration-induced wear.
• Industrial Automation
  • Critical Infrastructure: Used in steel mills, paper mills, and pharmaceutical plants with large rotating machinery requiring high-reliability vibration monitoring.
  • Distributed Control Systems (DCS): Integrates with GE Mark VI DCS to provide vibration data for plant-wide asset health management。
