Bently Nevada 330101-00-79-15-02-05 3300 XL 8 mm Probe, 3/8-24 UNF Thread

Technical Specifications Breakdown

Key parameters for the 330101-00-79-15-02-05 are listed below for quick reference:

Industry Applications and Operational ROI

Operators of steam turbines, centrifugal compressors, and large pumps frequently face false trips or undetected bearing wear due to unreliable vibration probes. Its 8 mm diameter provides thicker PPS encapsulation and a stronger case, offering superior resistance to physical abuse compared to smaller probes. By delivering consistent 7.87 V/mm scale factor over the linear range, this probe enables accurate trend data for predictive maintenance, reducing unplanned downtime and extending machinery life.

Installation and Setup Guidance

When installing the 330101-00-79-15-02-05, ensure the probe tip is clean and free of debris. Use the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration measurements. The miniature coaxial ClickLoc connector simplifies field wiring; use 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² or 16 to 24 AWG). Maximum field wiring length between the Proximitor sensor and monitor is 305 meters (1,000 feet). Always verify that the mounting thread (3/8-24 UNF) matches the machine's tapped hole to avoid cross-threading.

Maintenance and Reliability

Periodically inspect the probe cable and connector for signs of wear or damage. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. For applications with high humidity, note that the probe shows less than 3% change in Average Scale Factor when tested at 93% humidity per IEC 68-2-3 for up to 56 days. If an oil leak path through the cable interior is a concern, consider the optional FluidLoc cable option.

Robust Vibration Sensing for Critical Machinery

Industrial rotating machinery demands precise, reliable vibration monitoring to prevent unplanned downtime and catastrophic failures. The Bently Nevada 330101-00-79-15-02-05 3300 XL 8 mm probe offers a proven solution for measuring shaft relative vibration and position in harsh environments. This eddy-current probe is designed for permanent installation in compressors, turbines, pumps, and other rotating equipment where accuracy and durability are non-negotiable.

Compatibility and Integration

The 330101-00-79-15-02-05 is part of the Bently Nevada 3300 XL series and is compatible with 3300 XL Proximitor sensors and extension cables. The standard 1.5 meter system offers interchangeability error of ±5% over the linear range from 0°C to +45°C. For longer cable runs, the 9 meter system provides ±6.5% interchangeability. The probe carries CSA, ATEX, and IECEx approvals, making it suitable for hazardous area installations.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the total length option (1.5 meter in this model) and connector type (miniature coaxial ClickLoc).
