Product Description

The Bently Nevada 330906-02-12-10-12-05 is a high-performance, reverse-mount eddy current proximity probe system designed for critical rotating machinery protection and condition monitoring. As part of the 3300 XL NSv family, this sensor system is specifically engineered to provide reliable vibration and position measurements in space-constrained environments where standard front-mount probes cannot be utilized. It is a complete system comprising the NSv probe, an integrated extension cable, and is designed to interface seamlessly with 3300 XL NSv Proximitor sensors. This robust sensing solution is ideal for measuring radial vibration, axial position, and keyphasor signals on medium to large rotors, ensuring optimal machinery health and operational safety.

Key Features and Benefits

  • Space-Saving Reverse Mount Design: Allows installation from the rear of the mounting surface, making it perfect for congested areas or hazardous locations where front-side access is limited.
  • Compact and Robust Construction: Features a sealed, rugged probe body that resists oil ingress and withstands harsh industrial environments, ensuring long service life.
  • Enhanced Small Target Performance: The NSv design offers superior side-view and small-target characteristics compared to standard 5mm and 8mm sensors, providing stable measurements on smaller shafts.
  • System Interchangeability: Fully compatible with the industry-standard 3300 XL Proximitor sensor system, allowing for easy upgrades from older 3300 RAM or 3000/7000 series systems.
  • High-Temperature Tolerance: Engineered to handle elevated temperatures commonly found near bearings and in steam turbine applications.

Application Areas

  • Centrifugal Air & Process Gas Compressors
  • Refrigeration Compressors
  • Steam and Gas Turbines
  • Pumps and Motors with Fluid Film Bearings
  • Gearboxes and Generators
  • Machinery with Small Shafts (< 51 mm / 2 in) or Limited Radial Space

Installation and Maintenance

Installation:
  1. Preparation: Ensure the machine is shut down and locked out. Clean the mounting hole thoroughly to remove any debris or old thread sealant.
  2. Mounting: Insert the probe from the back side of the mounting surface. Secure it using the provided locknut and washer. Do not overtighten.
  3. Connection: Connect the integrated ClickLoc cable to the 3300 XL NSv Proximitor sensor. Ensure the connector is fully seated and locked.
  4. Gap Setting: Using a digital gap voltmeter, adjust the probe gap to the recommended center point (typically -9.0 V to -10.0 V DC for 7.87 mV/µm systems) as per API 670 standards.
Maintenance:
  • Visual Inspection: Regularly check the probe cable and connector for signs of wear, oil damage, or physical stress.
  • Signal Verification: Monitor the gap voltage and vibration signals on the monitoring system. A sudden shift in gap voltage or erratic vibration readings may indicate a probe or cable fault.
  • Electrical Testing: During scheduled outages, perform offline resistance and insulation tests on the probe system to verify coil integrity and cable insulation health.
  • Replacement: If the probe is suspected to be faulty, the most reliable confirmation method is to replace it with a known-good spare. Always use genuine Bently Nevada components to maintain system accuracy and warranty.
