Bently Nevada 3300 XL 8mm Proximity Probe: The Gold Standard for Industrial Precision

Bently Nevada 3300 XL 8mm Proximity Probe: The Gold Standard for Industrial Precision
A technical comparison of Bently Nevada’s 3300 XL 8mm proximity probe with competing eddy current sensors, focusing on critical parameters like frequency response, temperature resilience, and integration in high-stakes industrial automation systems.

Bently Nevada 3300 XL 8mm Proximity Probe: The Gold Standard for Industrial Precision

Key Features & Innovations

  • Frequency Response: 0–10 kHz (±1% linearity) for real-time monitoring of high-speed machinery like gas turbines.
  • Measurement Range: ±2 mm with ±1% linearity, ensuring ultra-precise displacement and vibration data.
  • Extreme Environment Resilience: Operates at -40°C to +150°C (standard) or up to 218°C (ETR probes) with IP67/IP68 protection against oil, dust, and moisture.
  • Durability: Patented TipLoc™ and CableLoc™ designs provide 330 N (75 lbf) pull-off resistance.
  • Integration: Pre-calibrated for AISI 4140 steel; compatible with Bently’s 3500 monitoring systems (e.g., 3500/25 vibration module).

Technical Specifications

  • Probe Dimensions: 8mm tip with 3/8-24 or M10x1 threading.
  • Cable Options: FluidLoc® oil-resistant cables and ETR (Extended Temperature Range) variants up to 260°C.
  • Output Signal: -200 mV/mil (-7.87 V/mm) sensitivity.
  • Power Supply: 12–30 VDC, 40 mA current limit.
  • Certifications: API 670 compliant for critical machinery in oil/gas and power sectors.

Industrial Applications

  • Radial vibration monitoring in turbines, compressors, and generators.
  • Axial displacement measurement in thrust bearings.
  • Keyphasor® timing and rotor speed analysis.

Why Choose Bently Nevada 3300 XL?

  • Superior Accuracy: ±1% linearity outperforms GE PH-1130 (±1.5%) and IFM PI2793 (±2%).
  • Long-Term Reliability: 1-year warranty with FluidLoc® cables reducing maintenance by 30%.
  • Global Availability: 3–5-day delivery via DHL, FedEx, or UPS.
  • Cost Efficiency: Integrated Proximitor eliminates external signal conditioning (saves 15–20% vs. GE PH-1130).
