Industry Applications
The Bently Nevada 330709-000-050-10-02-00 3300 XL 11 mm Proximity Probe excels in applications requiring precise shaft displacement and eccentricity measurements. Typical use cases include:
-
Steam Turbines: Monitor radial vibration and thrust position in high-speed turbines, where the probe's temperature resistance up to +177°C ensures reliable performance near hot casings.
-
Centrifugal Compressors: Detect shaft vibration and axial position in compressors used in petrochemical and gas processing plants. The 1.0 meter cable length simplifies routing to remote monitoring cabinets.
-
Large Electric Motors: Provide early warning of bearing wear and misalignment in motors driving pumps or fans. The PPS tip material resists chemical exposure in industrial environments.
Installation & Setup Guidance
Correct installation of the Bently Nevada 330709-000-050-10-02-00 is critical for accurate measurements. Follow these guidelines:
-
Thread Engagement: Ensure the M16x1.5 thread engages fully but do not exceed 24 mm maximum thread length. Use the recommended case torque of 63.3 N•m to secure the probe without damaging the case.
-
Cable Routing: Maintain a minimum bend radius of 25.4 mm (1.0 in) to avoid damaging the FEP-insulated cable. Secure the cable along its path to prevent vibration-induced wear.
-
Connector Torque: Tighten the ClickLoc connector finger-tight only. Do not exceed 0.565 N•m (5 in•lb) to prevent connector damage.
-
Target Surface: Use a flat target surface with a minimum diameter of 30.5 mm (1.2 in). For shaft measurements, the shaft diameter should be at least 152 mm (6.0 in) to avoid cross-talk limitations.
Maintenance & Reliability
To ensure long service life of the Bently Nevada 330709-000-050-10-02-00, perform periodic inspections:
-
Visual Checks: Inspect the cable and connector for cuts, kinks, or corrosion. Replace the probe if the cable jacket shows wear.
-
Resistance Test: Measure the DC resistance between the center conductor and outer conductor. It should read 5.9 ± 0.5 ohms for the 1.0 meter probe. Deviations indicate cable damage.
-
Temperature Considerations: Avoid exposing the probe to temperatures below -34°C (-30°F) during storage or operation, as this may cause premature failure of the pressure seal.
-
Cleaning: Wipe the probe tip with a soft, dry cloth. Do not use solvents that could damage the PPS tip.
Selection Guide & Purchasing Advice
When replacing or upgrading to the Bently Nevada 330709-000-050-10-02-00, verify the following:
-
Mechanical Fit: Confirm the mounting thread is M16x1.5 and that there is sufficient clearance for the 50 mm case length.
-
Cable Length: Choose the total probe length option to match your installation distance. For longer runs, variant 330709 series offers 5 and 9 meter options.
-
Agency Approvals: This unit carries agency approval option 00 (not required). If your application demands certification, contact UBEST Automation for approved variants.
