3. Advantages & Features

1. Ultra-Precision Measurement: BENTLY 135137-01 leverages digital signal filtering and linearization to achieve ±0.1% full-scale accuracy for shaft displacement—critical for detecting micro-movements that signal early-stage bearing degradation.
2. Multi-Parameter Capability: A single BENTLY 135137-01 module monitors shaft displacement, vibration, and thrust position, eliminating the need for multiple standalone modules and reducing 3500 rack space requirements by up to 40%.
3. Advanced Fault Detection: Built-in algorithms for rotor orbit analysis and trend tracking enable BENTLY 135137-01 to identify subtle fault patterns (e.g., synchronous vibration from misalignment) that basic monitoring systems miss.
4. Robust Environmental Performance: Rated for -40°C to +85°C operation and compliant with MIL-STD-810G for shock and vibration, BENTLY 135137-01 performs reliably in extreme environments like arctic power plants and desert compressor stations.
5. Seamless System Integration: Support for Modbus TCP/IP and 4–20 mA outputs ensures BENTLY 135137-01 integrates with existing control and analytics platforms, enabling plant-wide visibility of machinery health data.

4. Application Fields & Cases

4.1 Application Fields

• Power Generation: Gas/steam turbine shaft monitoring, generator rotor position tracking, boiler feed pump vibration analysis
• Oil & Gas: Pipeline compressor thrust position monitoring, LNG plant cryogenic pump shaft displacement, refinery hydrocracker reactor agitator vibration
• Petrochemical: Chemical plant centrifugal pump shaft monitoring, polymer extruder rotor alignment, ammonia synthesis reactor compressor vibration
• Manufacturing: Steel mill rolling mill roll eccentricity measurement, paper mill dryer cylinder shaft displacement

4.2 Typical Cases

1. Gas Turbine Power Plant Fault Prevention: A 500 MW combined-cycle power plant deployed BENTLY 135137-01 to monitor turbine shaft displacement and vibration. The module detected a 0.2 mm increase in radial displacement (caused by bearing wear) 6 weeks before failure would have occurred, allowing scheduled maintenance during a planned outage and avoiding a $2.5 million unplanned shutdown.
2. Natural Gas Compressor Station Thrust Protection: An interstate pipeline compressor station used BENTLY 135137-01 to track compressor thrust bearing position. When the module detected abnormal axial movement (indicating lubrication loss), it triggered an automatic shutdown, preventing seal damage and a 72-hour pipeline outage (valued at $1.8 million in lost revenue).
3. Refinery Reactor Compressor Monitoring: A petrochemical refinery integrated BENTLY 135137-01 into its hydrocracker reactor compressor system. The module’s vibration analysis identified rotor misalignment caused by foundation settling, enabling realignment before impeller damage occurred—reducing maintenance costs by $300,000 and extending compressor lifespan by 2 years.

6. Selection Suggestions & Precautions

6.1 Selection Suggestions

1. Machinery Type Matching: BENTLY 135137-01 is optimized for high-speed rotating equipment (≥1000 RPM) like turbines and compressors; for low-speed machinery (≤500 RPM), select Bently 135137-02 with extended low-frequency response.
2. Environment & Safety: Choose ATEX/IECEx-certified versions for explosive zones (e.g., refineries, offshore platforms); opt for IP65 enclosures for outdoor or dusty installations (e.g., mining pumps).
3. Integration Needs: Select modules with Modbus TCP/IP for cloud-based analytics (e.g., Bently Predix); choose 4–20 mA-only versions for legacy DCS integration to reduce costs.

6.2 Precautions

1. Sensor Wiring: Use shielded, twisted-pair Bently 3300 XL extension cables for probe connections; ground shielding at the module end only to eliminate ground loops. Tighten terminal screws to 1.5 N·m to prevent signal degradation.
2. Calibration Requirements: Calibrate BENTLY 135137-01 annually using Bently-certified calibration tools (e.g., Calibrator 9010); verify linearity across the full measurement range to maintain accuracy for early fault detection.
3. Maintenance Checks: Inspect probe alignment and cable integrity every 6 months; replace aging probe cables (≥5 years old) to prevent signal loss. Update module firmware via System 1® software to enable new fault-detection algorithms.
4. Installation Guidelines: Mount BENTLY 135137-01 in the 3500 chassis’s dedicated vibration/displacement slot; maintain 5 cm clearance from power modules to avoid heat interference. Avoid installation near VFDs or high-voltage equipment to minimize EMI.
