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.
