Bently Nevada 330100-90-00 3300 XL 8mm Proximitor Sensor — Precision Vibration Monitoring

The Bently Nevada 330100-90-00 is a high-performance 8mm Proximitor sensor engineered for critical vibration and position monitoring in industrial rotating machinery. Part of the renowned 3300 XL series, this eddy current proximity sensor delivers exceptional accuracy and reliability for turbines, compressors, pumps, motors, and other turbomachinery applications.

Technical Specifications

  • Model Number: 330100-90-00
  • Probe Type: 8mm Proximitor (Eddy Current)
  • Series: 3300 XL
  • Frequency Response: 0 to 10 kHz (-3 dB)
  • Operating Temperature: -40 °C to +105 °C (-40 °F to +221 °F)
  • Linear Range: 0.40 mm to 1.78 mm (16 to 70 mils)
  • Thread Size: M18 x 1.0
  • Cable Connection: Integral armored cable with TNC connector
  • Material: Stainless steel housing for harsh environments

Key Applications

This Proximitor sensor excels in demanding industrial environments where precise shaft displacement and vibration measurement are critical:

  • Steam and gas turbine monitoring
  • Centrifugal and axial compressor protection
  • Large motor and generator surveillance
  • Pump bearing condition assessment
  • Fan and blower vibration analysis
  • Gearbox shaft position tracking

Advanced Monitoring Solutions

When paired with compatible 3300 XL Proximitor extension cables and signal conditioning modules, the 330100-90-00 creates a complete monitoring system that detects early signs of mechanical degradation. The sensor’s eddy current technology provides non-contact measurement, eliminating wear and ensuring long-term stability in continuous operation.

Integration with Bently Nevada monitoring systems enables real-time data acquisition, trend analysis, and predictive maintenance strategies that reduce unplanned downtime and extend equipment lifespan.

Common Technical Questions

Q: What is the recommended gap voltage for the 330100-90-00?
A: The sensor operates optimally with a gap voltage of -10 Vdc when used with standard 3300 XL signal conditioning modules, providing 200 mV/mil output sensitivity.

Q: Can this sensor monitor both radial and axial vibration?
A: Yes, multiple 330100-90-00 sensors can be installed in orthogonal configurations to capture X-Y radial vibration and axial position simultaneously.

Q: Is the sensor compatible with non-ferrous target materials?
A: The 330100-90-00 is optimized for ferrous targets. For non-ferrous materials like aluminum or titanium, consult factory calibration data or consider alternative sensor configurations.

Q: What cable length options are available?
A: Standard integral cable lengths range from 1 to 9 meters. Extension cables can extend total system length up to 91 meters (300 feet) when properly matched.
