Bently Nevada 330103-00-05-05-01-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-05-05-01-05 are listed below for quick reference:

Industry Applications

Its extended temperature range (up to +218°C for the tip with optional range) makes it suitable for steam turbine applications where high heat is present. The CSA, ATEX, and IECEx approvals allow installation in hazardous areas, including Zone 0 gas environments when paired with intrinsic safety barriers.

Installation & Setup Guidance

For optimal performance, mount the probe using the M10 x 1 thread with a maximum engagement of 15 mm. Use 3-conductor shielded triad cable for field wiring (0.2 to 1.5 mm² / 16 to 24 AWG). The maximum cable length between the probe and the 3300 XL Proximitor Sensor is 305 meters (1,000 feet). Set the initial gap to -9 Vdc (approximately 1.27 mm / 50 mils) for radial vibration monitoring. Ensure the target surface is clean and free of magnetic irregularities.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage, especially in high-vibration or corrosive environments. The probe is designed to seal differential pressure between tip and case using a Viton® O-ring, but it is not pressure tested before shipment. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe maintains less than 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC 68-2-3.

Solving Vibration Monitoring Challenges in Harsh Environments

When rotating machinery operates under extreme temperatures or hazardous conditions, accurate vibration measurement becomes critical for predictive maintenance. The Bently Nevada 330103-00-05-05-01-05 3300 XL 8 mm Proximity Probe offers a proven solution for such demanding applications. This metric probe, with its M10 x 1 thread and polyphenylene sulfide (PPS) tip, is engineered to deliver reliable displacement data in environments where standard sensors fail.

Compatibility & Integration

The 330103-00-05-05-01-05 is part of the 3300 XL series and is compatible with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures secure, quick installation. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, follow drawing 140979.

Selection Guide & Purchasing Advice

When selecting a proximity probe, consider the required cable length, thread size, and agency approvals. The 330103-00-05-05-01-05 offers a 0.5 m cable, M10 x 1 thread, and CSA/ATEX/IECEx approvals, making it a versatile choice for global applications.

Troubleshooting & Common Issues

If the probe output is erratic, check the field wiring connections and ensure the cable is properly shielded. Verify that the gap setting is within the linear range (0.25 to 2.3 mm). If the signal is noisy, inspect the target surface for runout or damage. For high-temperature applications, confirm the probe temperature rating matches the environment. If the pressure seal fails, contact the custom design department for testing options.
