- Multi-Parameter Monitoring: Simultaneously tracks radial vibration, axial displacement, and shaft eccentricity for comprehensive machinery health assessment.
- Real-Time Alarm System: Configurable alarm thresholds with hysteresis to minimize false triggers and ensure prompt action.
- High Precision: 16-bit analog-to-digital conversion for accurate signal analysis.
- Rugged Design: Industrial-grade components with EMI/EMC protection for reliable operation in harsh environments.
- Flexible Configuration: Supports both internal and external terminal options for diverse installation needs.
Industries:
- Power generation (turbines, generators)
- Oil and gas (pumps, compressors)
- Manufacturing (rotating machinery)
Case Study:
A European power plant deployed the 128229-01 to monitor steam turbine vibrations. By detecting abnormal axial displacement trends, operators avoided a catastrophic failure, saving over $500,000 in repair costs.
The 128229-01 surpasses standard displacement modules with:
- Quadruple Channel Capacity: Supports 4 channels vs. typical 2-channel competitors.
- Integrated Safety Features: Built-in redundancy and fault isolation for critical applications.
- Lower Installation Cost: Reduces wiring complexity with integrated terminal blocks.
- System Compatibility: Ensure compatibility with the 3500 Rack and System 1™ software.
- Channel Requirements: Choose 4-channel configuration for multi-point monitoring.
- Environmental Conditions: Opt for external terminals if exposed to corrosive or high-vibration environments.
- Sensor Calibration: Calibrate eddy current sensors before installation using Bentley’s Proximitor® technology.
- Grounding: Maintain proper grounding to prevent signal interference.
- Firmware Updates: Regularly update firmware via Bentley’s System 1™ software for enhanced functionality.
