Bently Nevada 300103-00-05-10-02-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 300103-00-05-10-02-05 are listed below for quick reference:

Application in Rotating Machinery Protection

This proximity probe is commonly installed on steam turbines, compressors, pumps, and electric motors to monitor radial vibration and axial position. The 2 mm linear range and recommended -9 Vdc gap setting allow precise measurement of shaft motion relative to the bearing housing. With CSA, ATEX, and IECEx approvals, the probe is suitable for hazardous area installations, including Zone 0 and Zone 2 environments when paired with appropriate barriers or isolators.

Installation Guidance for Maintenance Engineers

When installing the 300103-00-05-10-02-05, ensure the probe tip is clean and the target surface is smooth and free of scratches. The M10 x 1 thread allows secure mounting with a maximum thread engagement of 15 mm. Use 3-conductor shielded triad cable (16 to 24 AWG) for field wiring, keeping the distance between the Proximitor Sensor and monitor under 305 meters (1,000 feet) to avoid signal roll-off. Verify the gap voltage at -9 Vdc using a multimeter before finalizing the installation.

Maintenance and Reliability Considerations

Periodically inspect the probe cable and connector for damage, especially in high-vibration or high-temperature areas. The probe tip material (PPS) resists many chemicals, but avoid prolonged exposure to temperatures below -34°C (-30°F) to prevent pressure seal failure. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; however, it is not pressure tested before shipment. For applications requiring a pressure seal test, contact the custom design department.

Precision Vibration Monitoring with the Bently Nevada 3300 XL Probe

For maintenance engineers responsible for rotating machinery reliability, the Bently Nevada 300103-00-05-10-02-05 3300 XL 8 mm Proximity Probe offers a trusted solution for shaft vibration and position measurement. This probe is designed for harsh industrial environments, providing accurate, non-contact sensing to detect early signs of bearing wear, imbalance, or misalignment.

Selection and Purchasing Advice

When selecting a replacement or spare probe, verify the total length, connector type, and agency approvals match your system requirements.
