The Bently 3300/35 is a high-precision monitoring module engineered by Baker Hughes (formerly Bently Nevada) for industrial machinery protection and condition monitoring. As a key component in the Bently 3300 series—an industry-standard platform for rotating equipment health management—it specializes in measuring critical mechanical parameters, including radial vibration, axial position, and differential expansion, for turbines, generators, compressors, and pumps. By providing real-time data on machinery performance, this module enables early detection of potential faults (e.g., misalignment, bearing wear, rotor imbalance), minimizing unplanned downtime and ensuring safe, reliable operation in power generation, oil & gas, petrochemical, and manufacturing industries.
- Integrates vibration, position, and expansion measurement into a single compact unit, eliminating the need for multiple dedicated monitors. This reduces cabinet space, wiring complexity, and overall system cost while simplifying maintenance.
- Compatible with Bently’s industry-proven eddy-current proximity probes, which provide non-contact, high-resolution measurements (0.1 mil / 0.0025 mm) of rotating shaft behavior—critical for detecting subtle faults in high-speed machinery (e.g., turbine rotors).
- Configurable Alarm/Trip Settings: Users can define custom thresholds for each parameter (e.g., “alert” at 25 mils vibration, “trip” at 50 mils) to trigger discrete relay outputs. This enables automated shutdown of machinery in critical conditions, preventing catastrophic damage.
- Signal Validation: Built-in diagnostics check for probe wiring faults (open/short circuits) and sensor degradation, ensuring measurement accuracy and reducing false alarms. Fault status is transmitted via Modbus for remote monitoring.
- Modbus RTU Communication: The RS485 port enables real-time data transfer to PLCs, DCS, or SCADA systems, allowing operators to monitor machinery health from a central control room. It also supports integration with Bently Nevada’s System 1® software for advanced analytics (e.g., trend analysis, predictive maintenance).
- Analog Output Flexibility: 4-20 mA outputs can be scaled to match specific measurement ranges (e.g., 4 mA = 0 mils, 20 mA = 254 mils vibration), ensuring compatibility with third-party monitoring equipment.
- Wide Operating Range: Functions reliably in temperatures from 0°C to +65°C and high humidity (10-95% non-condensing), making it suitable for harsh industrial environments (e.g., refineries, power plant turbine halls).
- Robust Construction: Industrial-grade components and surge protection (compliant with IEC 61000-4-2/4) withstand electrical noise and voltage spikes common in industrial power grids, ensuring stable long-term operation (MTBF ≥ 100,000 hours).
The Bently 3300/35 is a staple in rotating machinery monitoring across critical industries, including:
- Power Generation: Turbines (steam, gas, hydro), generators, and boiler feed pumps—monitoring shaft vibration and axial position to prevent rotor rub and bearing failure.
- Oil & Gas: Centrifugal compressors, pipeline pumps, and reciprocating engines in upstream (drilling) and downstream (refining) operations—detecting misalignment and imbalance to avoid unplanned shutdowns.
- Petrochemicals: Process pumps, fans, and agitators in chemical plants—tracking differential expansion in high-temperature equipment to ensure thermal stability.
- Manufacturing: Large motors, gearboxes, and paper machine rolls—monitoring vibration to extend equipment lifespan and maintain production efficiency.
- Condition: New or fully refurbished original Baker Hughes (Bently Nevada) module (100% authentic, tested to meet OEM performance standards).
- Warranty: 12-month warranty covering manufacturing defects (excludes damage from improper wiring, voltage surges, or physical impact).
- Technical Support: Access to Baker Hughes’ global service network, including installation manuals, calibration guides, and compatibility lists for probes/sensors. Our team provides remote assistance for configuration, troubleshooting, and integration with condition monitoring software.
- Packaging: Anti-static industrial packaging to protect sensitive electronic components during shipping and storage.
