Bently Nevada 330101-00-19-15-11-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Optimized Vibration Monitoring with the Bently Nevada 3300 XL 8 mm Probe

When machine reliability is critical, selecting the right proximity probe is essential. The Bently Nevada 330101-00-19-15-11-CN 3300 XL 8 mm Probe offers a robust solution for measuring shaft vibration and position in rotating machinery. This model features a 3/8-24 UNF thread, a 1.5 meter (4.9 feet) FluidLoc cable, and a miniature coaxial ClickLoc connector with connector protector, designed for demanding environments.

Technical Specifications Breakdown

Key parameters for the 330101-00-19-15-11-CN are listed below for quick reference:

Industry Applications

The patented TipLoc molding method provides a more robust bond between the probe tip and body, reducing failure risk in high-vibration environments. The FluidLoc cable option prevents oil leakage through the cable interior, making it suitable for lubricated machinery. By choosing this probe, you minimize unplanned downtime and extend equipment life.

Installation & Setup Guidance

For optimal performance, mount the probe with the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and the mounting surface is free of debris to maintain accurate readings.

Maintenance & Reliability

The probe’s stainless steel case and PPS tip resist corrosion and wear. The CableLoc design provides 330 N (75 lbf) pull strength for secure cable attachment. Inspect the probe and cable periodically for physical damage, especially in high-temperature or humid environments. The probe is designed to seal differential pressure with a Viton O-ring; contact the manufacturer if pressure testing is required for your application.

Compatibility & Integration

This probe is part of the 3300 XL system and works with compatible Bently Nevada extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector ensures a secure, quick connection. The system supports standard 5 or 1 meter and 9 meter configurations, with interchangeability error within ±5% to ±6.5% depending on the setup.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), cable length, and connector type. The 330101-00-19-15-11-CN is a popular choice for its robust design and FluidLoc cable. For availability and lifecycle status, contact AutoDCSTech, your trusted source for industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If readings are erratic, check the probe tip for contamination or damage. Verify the cable connection at the ClickLoc connector and ensure the field wiring is properly shielded and grounded. If the scale factor drifts, confirm that the probe is within the linear range (0.25 to 2.3 mm from target). For persistent issues, consult the Bently Nevada manual for the 3300 XL system.
