Bently Nevada 330103-00-04-10-02-05 3300 XL 8 mm Proximity Probe, Metric

Technical Specifications Breakdown

Key parameters for the 330103-00-04-10-02-05 are listed below for quick reference:

Industry Applications

Turbine Shaft Monitoring

In steam and gas turbines, the probe’s 2 mm linear range and -9 Vdc gap setting enable precise radial vibration measurement, helping operators detect early signs of imbalance or misalignment.

Compressor Protection

For centrifugal compressors, the 330103-00-04-10-02-05 provides continuous shaft position data. Its PPS tip and stainless steel case resist process contaminants, while CSA/ATEX/IECEx approvals allow use in hazardous areas.

Pump Health Assessment

In large industrial pumps, the probe’s extended temperature range (up to +177°C standard) and humidity tolerance (<3% ASF change at 93% RH) ensure stable readings even in demanding environments.

Installation & Setup Guidance

Mount the probe with M10x1 thread, ensuring maximum thread engagement of 15 mm. Use three-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) tinned field wiring. The maximum cable length between the probe and the 3300 XL Proximitor Sensor 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 rolloff at high frequencies with longer cable runs.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage or wear. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; contact the custom design department if pressure testing is required. Store in a clean, dry environment within the -52°C to +177°C range.

Solving Vibration Monitoring Challenges with Precision

In rotating machinery, undetected shaft vibration can lead to catastrophic failures and unplanned downtime. The Bently Nevada 330103-00-04-10-02-05 3300 XL 8 mm proximity probe provides accurate, non-contact displacement measurements essential for protecting critical assets like turbines, compressors, and pumps. This metric probe is engineered for harsh environments, offering reliable performance in temperature extremes and high humidity.

Compatibility & Integration

This probe is part of the 3300 XL series and is compatible with Bently Nevada Proximitor Sensors and monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga requirements. For non-incendive circuits per drawing 140979, it qualifies for Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc.

Selection Guide & Purchasing Advice

Choose the 330103-00-04-10-02-05 for applications requiring a metric, armored probe with CSA/ATEX/IECEx approvals. Verify your system’s thread size (M10x1) and cable length needs.
