Industrial Applications
Steam & Gas Turbines
Monitor bearing vibration and shaft displacement in power generation turbines. Dual channels enable simultaneous X-Y radial vibration measurement for orbit analysis.
Centrifugal Compressors
Protect critical compressor trains in oil & gas facilities. API 670 compliance ensures machinery protection system certification.
Large Motors & Generators
Track rotor vibration in electric motors and generators above 1,000 HP. Early fault detection prevents catastrophic bearing failures.
Pumps & Fans
Monitor vibration in critical process pumps and induced draft fans. Reduce unplanned maintenance and extend equipment life.
Installation & Configuration
Mounting Options
- DIN Rail Mount – Snap module onto standard 35mm DIN rail in control cabinet
- Panel Mount – Use mounting brackets for direct panel installation
- Rack Mount – Install in 3300 series monitoring rack (requires rack chassis)
Configuration Steps
- Connect proximity probes or accelerometers to input terminals
- Set measurement range using DIP switches or software configuration
- Program alarm setpoints (Alert and Danger levels)
- Connect 4-20mA output to DCS/PLC analog input
- Wire relay contacts to machinery shutdown system
- Apply 24V DC power and verify LED indicators
- Calibrate using known vibration source or signal generator
Alarm Configuration
Two-Stage Alarm System
- Alert Level: Early warning of abnormal vibration (typically 70% of trip level)
- Danger Level: Critical alarm triggers machinery shutdown (API 670 trip level)
Typical Setpoints (ISO 10816)
| Machine Type | Alert (mm/s RMS) | Danger (mm/s RMS) |
|---|---|---|
| Small machines (<15 kW) | 4.5 | 7.1 |
| Medium machines (15-75 kW) | 7.1 | 11.2 |
| Large machines (>75 kW) | 11.2 | 18.0 |
| Turbines (rigid foundation) | 7.1 | 11.2 |
Troubleshooting
| Problem | Cause | Solution |
|---|---|---|
| No output signal | Sensor disconnected | Check sensor wiring, verify continuity |
| Erratic readings | Electrical noise | Verify grounding, separate from power cables |
| Alarm relay stuck | Relay failure | Replace module or use alternate relay output |
| 4-20mA output incorrect | Calibration drift | Recalibrate using signal generator |

FAQ
Q: What is the difference between 3300/03 and 3300/05 modules?
A: 3300/03 is a dual-channel monitor. 3300/05 is a single-channel monitor with additional features.
Q: Can I use this module with non-Bently Nevada sensors?
A: Not recommended. Module is calibrated for Bently Nevada sensor specifications.
Q: How often should I recalibrate the module?
A: API 670 recommends annual calibration verification. Full recalibration every 3-5 years.
Q: Can I hot-swap this module?
A: Yes, if installed in a 3300 series rack with redundant power. Standalone installations require shutdown.
