Bently Nevada 330901-00-09-10-02-05 3300 NSv Proximity Probe

Bently Nevada 330901-00-09-10-02-05 3300 NSv Proximity Probe

The Bently Nevada 330901-00-09-10-02-05 represents a specialized solution in the 3300 NSv (Narrow Space Vibration) Proximity Probe family, engineered specifically for machinery installations where conventional probe mounting is constrained by limited radial clearance.

Technical Specifications

• Model Number: 330901-00-09-10-02-05
• Series: 3300 NSv Proximity Probe System
• Probe Length: 9 mm active tip extension
• Thread Size: 10 mm x 1.0 metric thread
• Cable Termination: 2-pin connector (05 configuration)
• Operating Temperature: -40 °C to +105 °C (-40 °F to +221 °F)
• Frequency Response: 0 to 10 kHz (-3 dB)
• Linear Range: 0.50 to 1.40 mm (20 to 55 mils)
• Sensitivity: 200 mV/mil (7.87 mV/ ¼m) nominal

Application Scenarios

This NSv probe excels in monitoring applications where space constraints prevent standard 8mm probe installation:

• Centrifugal Compressors: Radial vibration measurement on high-speed impellers with tight bearing housings
• Process Gas Compressors: Shaft displacement monitoring in multi-stage configurations
• Small Frame Turbines: Rotor position tracking in compact generator sets
• Gearbox Monitoring: Pinion shaft vibration analysis in confined gear casings
• Pump Applications: Critical machinery protection in vertical and horizontal pump designs

Key Features & Benefits

• Compact Design: Narrow profile enables installation in restricted radial spaces down to 12mm clearance
• High Reliability: Hermetically sealed construction withstands harsh industrial environments including moisture, oil mist, and chemical exposure
• Precision Measurement: Factory-calibrated system ensures accurate vibration and position data for predictive maintenance programs
• System Compatibility: Fully compatible with Bently Nevada 3300 XL, 3500, and System 1 monitoring platforms
• Extended Service Life: Ruggedized cable assembly and connector design minimize field failures

Installation & Integration

The 330901-00-09-10-02-05 integrates seamlessly with existing Bently Nevada monitoring infrastructure. The probe requires pairing with a compatible proximitor (such as the 3300 XL 11mm or 3300 XL 8mm proximitor) and extension cable system. Proper installation includes verification of target material conductivity, surface finish validation, and gap voltage calibration to achieve optimal measurement accuracy.

Common Technical Questions

Q: What is the minimum target area required?
A: The probe requires a minimum target area of 3x the probe tip diameter, approximately 30mm diameter for reliable operation.

Q: Can this probe measure axial position?
A: Yes, when installed axially with appropriate thrust collar targets, it provides accurate shaft position measurement within the linear range.

Q: What cable length options are available?
A: This configuration (05) typically supports extension cables from 1 to 9 meters when used with appropriate Bently Nevada extension cable assemblies.

Q: Is recalibration required after installation?
A: The probe-proximitor system is factory-calibrated as a matched pair. Field gap voltage verification is recommended but full recalibration is not typically required.

Warranty & Support

All units include a comprehensive 12-month manufacturer warranty covering defects in materials and workmanship. Technical support and application engineering assistance are available to ensure successful integration into your condition monitoring program.
