Bently Nevada 330140-08-05-01-00-00 3300 XL 8mm Proximity Probe

The Bently Nevada 330140-08-05-01-00-00 is a high-precision 8mm proximity probe engineered for continuous shaft position and vibration monitoring in critical rotating machinery. Part of the industry-proven 3300 XL platform, this sensor delivers reliable non-contact measurement for turbines, compressors, pumps, and motors across power generation, oil & gas, and heavy industrial applications.

Technical Specifications

• Probe Diameter: 8mm
• Frequency Response: 0 to 10 kHz (-3dB)
• Linear Range: 0.4 to 2.0 mm (typical)
• Operating Temperature: -40 °C to +125 °C (-40 °F to +257 °F)
• Cable Length: 5 meters (customizable)
• Thread Size: M8 x 1.0
• Material: Stainless steel housing with PTFE insulation
• Compatibility: 3300 XL Proximitor sensors and monitors

Key Applications

This proximity probe excels in demanding environments where accurate displacement and vibration data are mission-critical:

• Steam and gas turbine shaft vibration monitoring
• Centrifugal compressor radial position tracking
• Pump thrust bearing wear detection
• Motor rotor eccentricity measurement
• Gearbox condition monitoring systems

Solution Benefits

Integrating the 330140-08-05-01-00-00 into your machinery protection system provides:

• Early Fault Detection: Identifies bearing wear, misalignment, and rotor rubs before catastrophic failure
• Extended Uptime: Enables predictive maintenance scheduling to minimize unplanned shutdowns
• Harsh Environment Durability: Withstands extreme temperatures, vibration, and electromagnetic interference
• Seamless Integration: Direct compatibility with existing 3300 XL monitoring infrastructure
• Long-Term Stability: Proven sensor technology with minimal drift over operational life

Installation & Configuration

The probe mounts directly into machined holes on bearing housings or casings using standard M8 threads. Proper gap setting (typically 1.0-1.5mm) ensures optimal linearity and sensitivity. Pair with Bently Nevada Proximitor sensors and extension cables for complete system deployment. Consult factory documentation for target material compatibility and calibration procedures.

Frequently Asked Questions

Q: What target materials are compatible with this probe?
A: The 330140-08-05-01-00-00 works with ferromagnetic materials including carbon steel, stainless steel 400 series, and most turbine shaft alloys. Non-magnetic materials require specialized probes.

Q: Can I use this probe with non-Bently Nevada monitoring systems?
A: While designed for 3300 XL systems, the probe outputs a standard eddy current signal compatible with many third-party proximitor interfaces. Verify voltage and impedance specifications before integration.

Q: What is the recommended calibration interval?
A: Factory calibration is stable for 5+ years under normal conditions. Annual verification is recommended for critical safety systems or per regulatory requirements.

Q: How do I identify probe wear or damage?
A: Inspect the probe tip for physical damage, corrosion, or coating wear. Electrical testing should confirm coil resistance within specification (typically 7-9 ohms). Replace if readings deviate significantly.
