3. Advantages and Features
Multi-Sensor Flexibility: Supports proximity transducers, RPTs, and LVDTs for versatile machinery monitoring.
Dual-Channel Operation: Each pair of channels can monitor two parameters simultaneously (e.g., axial position + differential expansion).
Hazardous Area Compliance: Certified for use in explosive environments, ensuring safety in oil & gas and petrochemical industries.
Hot-Swap Capability: Enables module replacement without system shutdown, minimizing downtime.
Case Study: A power plant reduced unplanned outages by 25% using the 135137-01 to detect early-stage axial displacement in steam turbines.
4. Application Areas and Use Cases
Industries: Oil & gas, power generation, petrochemical, manufacturing.
Key Applications:
Axial position monitoring in turbines and compressors.
Differential expansion tracking in rotating machinery.
Valve position control in process systems.
5. Competitor Comparison
The 135137-01 outperforms alternatives with:
Wider Sensor Compatibility: Supports LVDTs and RPTs, unlike many single-sensor modules.
Enhanced Safety: Multiple explosion-proof certifications for use in Zone 0/1/2.
Higher Precision: Maintains ±0.1% accuracy for analog inputs.
6. Selection Recommendations
Compatibility: Ensure integration with existing 3500 Series racks and sensors.
Environment: Verify temperature and hazardous area ratings match site conditions.
Scalability: Choose based on channel requirements (e.g., 4 channels for large-scale systems).
7. Precautions
Sensor Calibration: Use BENTLY-approved sensors and recalibrate annually.
Installation: Follow API 670 guidelines for wiring and grounding.
Firmware Updates: Regularly update firmware for optimal performance.
