3. Advantages and Features
- Dual-Channel Redundancy: Simultaneous monitoring of two critical vibration parameters (e.g., X and Y directions).
- API/ISO Compliance: Direct support for API 670 safety systems and ISO 10816 vibration severity guidelines.
- Adaptive Filtering: Advanced signal processing reduces noise interference for accurate measurements.
- User-Configurable: Customizable alarm levels and analog outputs via BENTLY’s 3500 Software.
- Self-Diagnostics: Front-panel LEDs indicate sensor faults or module errors.
4. Application Areas and Use Cases
Industry Applications:
Industry Applications:
- Oil & Gas: Centrifugal pumps, gas turbines.
- Power Generation: Steam turbines, generators.
- Water Treatment: High-speed pumps.
Case Study: A European power plant reduced vibration-related downtime by 35% using the 3500/33 to monitor a steam turbine. Early detection of rotor imbalance allowed proactive maintenance, avoiding costly repairs.
5. Competitor Comparison
- Multi-Parameter Support: Simultaneous amplitude and phase monitoring in a single module, unlike some competitors requiring separate units.
- Software Integration: Native compatibility with BENTLY’s 3500 Series software for unified data management.
- Sensor Flexibility: Supports both proximity and velocity sensors, offering broader application coverage.

6. Selection Recommendations
- Sensor Type: Choose proximity probes for shaft displacement or velocity sensors for casing vibration.
- Rack Expansion: Ensure 3500 Rack slots are available for additional modules (e.g., temperature or process variables).
- Alarm Configuration: Adjust thresholds based on ISO 10816 vibration severity classes.
7. Precautions
- Probe Installation: Maintain precise probe alignment (<±0.05 mm) to avoid measurement errors.
- Grounding: Isolate signal cables from power lines to prevent EMI.
- Calibration: Verify sensor linearity annually using BENTLY’s 3500/05 Calibration Interface.
