Bently Nevada 330102-00-40-10-01-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330102-00-40-10-01-00 are listed below for quick reference:

Industrial Applications for Reliable Machine Protection

This proximity probe is engineered for harsh industrial environments. Its robust stainless steel case and PPS tip withstand extreme temperatures and humidity. Typical applications include:

• Turbine and Compressor Monitoring: The 2 mm linear range and -9 Vdc gap setting allow precise measurement of shaft vibration and position, helping prevent catastrophic failures.
• Pump and Motor Protection: With a temperature range from -52°C to +177°C, this probe performs reliably in both cryogenic and high-heat processes.
• Hydrocarbon Processing: The probe's intrinsic safety approvals (Class I, Zone 0, AEx/Ex ia IIC T5...T1 Ga) make it suitable for explosive atmospheres when used with approved barriers.

Installation and Setup Guidance

Proper installation is critical for accurate readings. The 330102-00-40-10-01-00 uses a 3/8-24 UNF thread with a maximum thread engagement of 0.563 in. Ensure the probe is mounted securely without over-tightening. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable. The maximum distance between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Refer to the frequency response graphs for signal rolloff at high frequencies with longer cable runs.

Maintenance and Reliability

To maintain accuracy, inspect the probe tip and cable periodically for physical damage. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe's relative humidity performance shows less than 3% change in Average Scale Factor after 56 days at 93% humidity per IEC 68-2-3.

High-Precision Vibration Monitoring with the Bently Nevada 3300 XL Probe

When machine reliability is critical, accurate vibration measurement is non-negotiable. The Bently Nevada 330102-00-40-10-01-00 3300 XL 8 mm Proximity Probe delivers the precision and durability needed for continuous protection of rotating machinery. Designed for radial vibration and position monitoring, this probe provides a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, corresponding to about 1.27 mm (50 mils).

Compatibility and Integration

It supports both intrinsic safety (with zener barriers per drawing 141092 or galvanic isolators) and non-incendive installations (per drawing 140979). The miniature coaxial ClickLoc connector simplifies field replacement and ensures a reliable connection.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the total length, thread type, and cable option. The 330102-00-40-10-01-00 is a 1.0 meter probe with 3/8-24 UNF thread and armor.
