Bently Nevada 330103-01-06-05-02-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-01-06-05-02-05 are listed below for quick reference:

Industry Applications

Turbomachinery Protection

In steam turbines and compressors, the probe's 2 mm linear range and -9 Vdc gap setting provide precise shaft vibration monitoring. The PPS tip and stainless steel case resist high temperatures up to +177°C, ensuring reliable data in critical rotating equipment.

Pump and Motor Monitoring

For large pumps and motors, the 0.5 meter cable length allows flexible placement near the bearing housing. The miniature coaxial ClickLoc connector simplifies installation while maintaining signal integrity over long field wiring runs up to 305 meters.

Hazardous Area Compliance

With CSA, ATEX, and IECEx approvals, this probe is suitable for Class I, Zone 0 and Zone 2 environments when installed with appropriate barriers. This reduces the risk of ignition in gas and dust atmospheres, a key factor for chemical and oil & gas facilities.

Installation & Setup Guidance

Mount the probe with the M10x1 thread, ensuring thread engagement does not exceed 15 mm. Use 3-conductor shielded triad cable (16 to 24 AWG) for field wiring. Set the initial gap to approximately 1.27 mm (50 mils) to achieve -9 Vdc output for radial vibration measurements. Verify the probe tip is clean and free of debris before final tightening.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage or corrosion, especially in high-humidity environments (up to 93% RH). The probe's pressure seal uses a Viton O-ring; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure. No internal calibration is required under normal conditions.

Compatibility & Integration

This 3300 XL probe works with Bently Nevada Proximitor sensors and monitoring systems. The standard cable and miniature coaxial ClickLoc connector ensure straightforward integration. For intrinsically safe installations, refer to drawing 141092 for zener barriers or galvanic isolators. For non-incendive circuits, use drawing 140979.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size (M10x1), overall case length (60 mm), and total length (0.5 m). AutoDCSTech stocks this model and can assist with lifecycle status and availability. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If the output voltage drifts outside the -1 to -17 Vdc range, check the probe gap and target surface condition. High resistance readings (above 7.95 Ω) may indicate cable damage or connector corrosion. For signal noise, ensure field wiring does not exceed 305 meters and is routed away from high-voltage cables. If the probe fails to respond, inspect the ClickLoc connector for secure mating.
