BENTLY 3500/44-01-00 Aeroderivative GT Vibration Monitor
1. Product Description
The BENTLY 3500/44-01-00 is a high-performance, four-channel vibration monitor designed for aeroderivative gas turbine applications. As part of the BENTLY 3500 modular monitoring system, it continuously tracks critical parameters like axial displacement, vibration amplitude, and rotor dynamics to prevent machinery failures. The monitor supports configurable alarm setpoints and integrates with BENTLY’s System 1 software for advanced analytics. Its compact design and hot-swap capability enable easy installation in harsh industrial environments, ensuring minimal downtime during maintenance.

3. Advantages and Features
- Multi-Mode Monitoring: Configurable with up to 8 alarm parameter sets per channel, allowing seamless adaptation to varying machine modes (e.g., startup, full load).
- Real-Time Alarms: Compares measured data against user-defined thresholds to trigger alerts and shutdowns, reducing unplanned downtime.
- Flexible Signal Processing: Supports signal integration, 1X vibration tracking, and band-pass filtering for detailed fault analysis.
- Hot-Swap Design: Enables module replacement without powering down the entire system, enhancing operational continuity.
4. Application Fields and Case Studies
- Energy: Monitoring gas turbine rotor stability during load changes.
- Oil & Gas: Detecting bearing wear in offshore compressor trains.
- Manufacturing: Analyzing gearbox vibrations in high-speed production lines.
Case Study: A power plant reduced maintenance costs by 30% using the 3500/44-01-00 to predict turbine blade fatigue through real-time vibration trend analysis.
5. Competitor Comparison
The 3500/44-01-00 stands out with:
- Simultaneous dual-keyphasor tracking for precise phase analysis (vs. single-keyphasor alternatives).
- Built-in support for aeroderivative gas turbine-specific parameters (e.g., axial displacement).
- Higher channel density (4 channels in a single slot) compared to legacy 2-channel modules.
