Bently Nevada 330102-22-58-10-02-00 3300 XL 8 mm Proximity Probe

Precision Vibration Monitoring with the Bently Nevada 330102-22-58-10-02-00

Rotating machinery reliability depends on accurate shaft vibration and position measurements. The Bently Nevada 330102-22-58-10-02-00 3300 XL 8 mm Proximity Probe delivers the proven eddy current sensing technology needed for critical asset protection. This probe is designed for continuous, non-contact measurement of radial vibration and axial position in turbines, compressors, pumps, and other industrial rotating equipment.

Technical Specifications Breakdown

Key parameters for the 330102-22-58-10-02-00 are listed below for quick reference:

Industry Applications for the 3300 XL Probe

Typical applications include:

• Steam and Gas Turbines: Monitor shaft radial vibration and thrust position to prevent catastrophic failures. The 2 mm linear range and -9 Vdc recommended gap setting provide stable, repeatable data for protective monitoring systems.
• Centrifugal and Axial Compressors: Detect rotor dynamic changes early. The PPS tip withstands harsh process conditions, while the stainless steel case resists corrosion.
• Pumps and Electric Motors: Use for shaft relative vibration monitoring in critical rotating assets. The 330102-22-58-10-02-00 integrates with Bently Nevada 3300 XL Proximitor sensors and monitoring systems.

Installation and Setup Guidance

Proper probe installation is critical for accurate measurements. Follow these engineer-level guidelines:

• Thread Engagement: The 3/8-24 UNF thread has a maximum engagement length of 0.563 in. Ensure the probe is threaded into a properly tapped hole to this depth to avoid mechanical interference.
• Field Wiring: Use 3-conductor shielded triad cable with tinned wiring (16 to 24 AWG). The maximum distance between the Proximitor sensor and monitor is 305 meters (1,000 feet). Account for signal rolloff at high frequencies with longer cable runs.
• Gap Setting: For radial vibration applications, set the initial gap to -9 Vdc (approximately 1.27 mm or 50 mils from the target). This places the probe in the center of its linear range.
• Pressure Sealing: The probe uses a Viton O-ring for differential pressure sealing. Contact the custom design department if pressure testing is required for your application.

Maintenance and Reliability

The 3300 XL probe is built for long-term reliability in demanding environments. Key maintenance considerations:

• Temperature Limits: The standard probe operates from -52°C to +177°C. Extended temperature range versions are available for probe tips up to +218°C and cables up to +260°C. Exposing the probe to temperatures below -34°C may cause premature pressure seal failure.
• Humidity Resistance: The probe shows less than 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC 68-2-3 for up to 56 days.
• Intrinsic Safety: When installed with approved zener barriers (drawing 141092) or galvanic isolators, the probe is suitable for Class I, Zone 0 hazardous areas (AEx/Ex ia IIC T5...T1 Ga). For non-incendive installations (drawing 140979), it meets Class I, Zone 2 requirements (AEx/Ex nA IIC T5...T1 Gc).

Selection Guide and Purchasing Advice

When selecting a replacement or new proximity probe, verify the total length, thread type, and connector configuration match your existing system.
