Bently Nevada 330103-00-14-50-02-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-14-50-02-00 are listed below for quick reference:

Industry Applications for Reliable Vibration Monitoring

Steam and Gas Turbine Protection

In power generation, the probe’s 2 mm linear range and -9 Vdc gap setting allow precise radial vibration and thrust position measurement. The PPS tip withstands high temperatures up to +177°C standard, ensuring continuous operation in turbine bearing housings.

Compressor and Pump Monitoring

For centrifugal compressors and large pumps, the 5.0-meter cable length pairs with the 5 meter Proximitor sensor for seamless integration. The M10 x 1 thread and 15 mm maximum thread engagement simplify installation into existing bearing brackets.

Critical Rotating Machinery in Harsh Environments

The stainless steel case (AISI 303/304) and Viton® O-ring seal provide resistance to moisture and contaminants. The probe maintains less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3, making it suitable for offshore and chemical plant applications.

Installation & Setup Guidance

Mount the probe with the M10 x 1 thread, ensuring thread engagement does not exceed 15 mm. Use 3-conductor shielded triad cable (0.2 to 1.5 mm² / 16 to 24 AWG) for field wiring. Maximum cable length between the Proximitor sensor and monitor is 305 meters (1,000 feet). For radial vibration, set the initial gap to -9 Vdc (approximately 1.27 mm or 50 mils). Refer to frequency response graphs for signal roll-off at high frequencies with longer cable runs.

Maintenance & Reliability

Inspect the probe cable and connector periodically for wear or damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe is not pressure tested before shipment; contact the custom design department if pressure seal testing is required. Store in a clean, dry environment within the -52°C to +177°C range.

Compatibility & Integration

This 5.0-meter probe is designed exclusively for use with the 5 meter Proximitor sensor. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, the probe is rated Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga. For non-incendive circuits per drawing 140979, it is rated Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. Always verify compatibility with your monitoring system before installation.

Selection Guide & Purchasing Advice

When ordering the 330103-00-14-50-02-00, confirm the required total length (5.0 meters) and connector type (miniature coaxial ClickLoc). AutoDCSTech stocks genuine Bently Nevada parts to ensure authentic performance. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If the probe output is erratic, check the field wiring for continuity and proper shielding. Verify that the Proximitor sensor matches the 5.0-meter probe length. For no output, inspect the ClickLoc connector for damage and ensure the target is within the linear range (0.25 to 2.3 mm from target). If the pressure seal fails, replace the probe and avoid operation below -34°C.
