Applications:
Shaft vibration and displacement monitoring.
Eccentricity and misalignment detection.
Predictive maintenance systems.
Case Example: A petrochemical plant used 140734-01 to monitor compressor axial displacement, preventing a $300,000 production loss due to seal failure.
5. Competitive Comparison
The 140734-01 outperforms similar modules with:
Higher Resolution: 24-bit vs. standard 16-bit in competing products.
Wider Temperature Range: Operates in -40°C to +85°C, surpassing most alternatives.
Integrated Redundancy: Dual-channel design eliminates single points of failure.
6. Selection Recommendations
System Compatibility: Ensure compatibility with BENTLEY 3500 racks and proximity sensors.
Environmental Needs: Prioritize this module for high-temperature or high-vibration settings.
Scalability: Pair with additional modules (e.g., 149992-01 relay outputs) for comprehensive monitoring.
7. Precautions
Installation: Power down the system before module replacement.
Calibration: Perform annual sensor calibration to maintain accuracy.
Environmental Limits: Avoid exposure to condensation or corrosive gases.
