Bently Nevada 330101-00-49-10-02-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread

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

Industrial machinery reliability depends on accurate, durable vibration sensing. The Bently Nevada 330101-00-49-10-02-05 3300 XL 8 mm Probe offers a proven solution for critical rotating equipment monitoring. This probe is designed for applications requiring precise shaft vibration and position measurements, even in harsh environments.

Technical Specifications Breakdown

Key parameters for the 330101-00-49-10-02-05 are listed below for quick reference:

Industry Applications

The 2 mm linear range covers typical vibration amplitudes, while the -9 Vdc recommended gap ensures optimal sensitivity.

Installation & Setup Guidance

When installing the 330101-00-49-10-02-05, ensure the probe case thread (3/8-24 UNF) engages properly. Maximum thread engagement is 0.563 in. For standard forward mounted probes, recommended torque is 11.2 N•m (100 in•lbf) for the case and 7.5 N•m (66 in•lbf) for the first three threads. Use a 3-conductor shielded triad cable (16 to 24 AWG) for field wiring, with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and monitor. The miniature coaxial ClickLoc connector simplifies cable attachment.

Maintenance & Reliability

The patented TipLoc molding method provides a robust bond between probe tip and body, while the CableLoc design offers 330 N (75 lbf) pull strength. The probe is designed to seal differential pressure between tip and case using a Viton O-ring. For extended temperature range applications, the probe tip can operate up to +218°C (+425°F). Periodic inspection of cable integrity and connector cleanliness is recommended. Exposing the probe to temperatures below –34˚C (-30˚F) may cause premature failure of the pressure seal.

Compatibility & Integration

This probe is part of the 3300 XL system and works with 3300 XL Proximitor Sensors and extension cables. The standard 5 or 1 meter system provides an ISF of 7.87 V/mm ± 5% over 0°C to +45°C. For 9 meter systems, ISF is ± 6.5%. The deviation from best fit straight line (DSL) is less than ±0.025 mm (±1 mil) for standard 5 or 1 meter systems. The probe is approved for use in hazardous areas with CSA, ATEX, and IECEx certifications.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the unthreaded length, overall case length, and total length match your mounting requirements. The 330101-00-49-10-02-05 with 1.0 meter cable and ClickLoc connector suits most standard installations. Contact AutoDCSTech for availability and lifecycle status before ordering.

Troubleshooting & Common Issues

If you observe erratic readings, first check the cable connection at the ClickLoc connector and inspect for damage. Verify the probe tip is clean and free of debris. Ensure the gap voltage is set to approximately -9 Vdc. If the probe is exposed to temperatures below –34˚C (-30˚F), the pressure seal may fail prematurely. For extended temperature applications, use the ETR probe variant rated up to +218°C (+425°F) for the tip. Always follow manufacturer guidelines for torque and thread engagement.
