Bently Nevada 330103-02-08-10-02-00 3300 XL 8 mm Proximity Probe, Metric

Technical Specifications Breakdown

Key parameters for the 330103-02-08-10-02-00 are listed below for quick reference:

Industry Applications: Protecting Critical Assets

This proximity probe is widely used in turbomachinery, compressors, pumps, and motors. The 2 mm linear range and -9 Vdc recommended gap setting make it suitable for radial vibration and thrust position monitoring. The PPS tip and stainless steel case withstand high temperatures and corrosive environments, ensuring long-term reliability. The miniature coaxial ClickLoc connector simplifies field wiring, reducing installation time.

Installation & Setup Guidance

For optimal performance, mount the probe with the M10x1 thread into a drilled and tapped hole. Ensure the maximum thread engagement of 15 mm is not exceeded. Use 3-conductor shielded triad cable (0.2 to 1.5 mm² / 16 to 24 AWG) for field wiring. 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 or 50 mils) for radial vibration measurements. Always follow the manufacturer's installation manual.

Maintenance & Reliability

Inspect the probe cable and connector periodically for damage or wear. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring. If a pressure test is required, contact the custom design department. The probe's relative humidity performance shows less than a 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC 68-2-3.

Reliable Vibration Monitoring with Bently Nevada 330103-02-08-10-02-00

For industrial rotating machinery, accurate vibration measurement is critical to prevent unplanned downtime and catastrophic failures. The Bently Nevada 330103-02-08-10-02-00 is a 3300 XL 8 mm Proximity Probe designed for precise, non-contact displacement measurements. This metric probe features an M10x1 thread, a 1.0 meter (3.3 feet) cable with a miniature coaxial ClickLoc connector, and a polyphenylene sulfide (PPS) tip. It is engineered for harsh environments, with a standard temperature range of -52°C to +177°C (-62°F to +350°F) and a probe case made of AISI 303 or 304 stainless steel.

Compatibility & Integration

This probe is part of the 3300 XL system and is compatible with 3300 XL Proximitor Sensors and monitoring systems. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, follow drawing 140979. The probe carries hazardous area approvals for Class I, Zone 0 and Zone 2 environments as specified.

Selection Guide & Purchasing Advice

When selecting a replacement or spare probe, verify the part number 330103-02-08-10-02-00 matches your system requirements. AutoDCSTech stocks genuine Bently Nevada products with fast worldwide shipping. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If readings are erratic, check the cable and connector for continuity or damage. Verify the probe gap is within the linear range (0.25 to 2.3 mm). Ensure the target material is compatible and the probe is not contacting the shaft. For signal roll-off at high frequencies with long cable runs, refer to the frequency response graphs in the manual.
