Bently Nevada 330103-00-07-10-02-CN 3300 XL 8 mm Proximity Probe, Metric

Technical Specifications Breakdown

Key parameters for the 330103-00-07-10-02-CN are listed below for quick reference:

Industry Applications

Typical uses include:

• Steam and Gas Turbines: Monitor shaft radial vibration and thrust position, leveraging the probe's extended temperature range up to 218°C at the tip for close-coupled installations.
• Centrifugal Compressors: The PPS tip and stainless steel case resist process contaminants, while the 2 mm linear range captures full-scale vibration in high-speed rotating equipment.
• Pumps and Fans: Install with standard or extended cable lengths up to 305 meters (1,000 feet) between the probe and monitor, allowing flexible placement in large facilities.

Installation & Setup Guidance

Proper installation is critical for accurate readings. Follow these guidelines:

• Thread Engagement: Maximum thread engagement is 15 mm. Do not exceed this depth to avoid damaging the probe tip.
• Field Wiring: Use 0.2 to 1.5 mm² (16 to 24 AWG) wire. A 3-conductor shielded triad cable with tinned ends is recommended. Maximum field wiring length is 305 meters (1,000 feet) to the monitor.
• Gap Setting: For radial vibration, set the gap to -9 Vdc, which corresponds to approximately 1.27 mm (50 mils) from the target. This ensures operation within the linear range.
• Pressure Seal: The probe uses a Viton® O-ring to seal differential pressure. Probes are not pressure tested before shipment; contact the custom design department if a pressure seal test is required.

Maintenance & Reliability

To maintain measurement integrity:

• Inspect the probe tip and cable periodically for physical damage or contamination. Clean with a soft, lint-free cloth if needed.
• Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal.
• The probe is designed for less than 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days, confirming its reliability in humid environments.

Precision Vibration Monitoring for Critical Machinery

In rotating machinery, undetected shaft vibration can lead to catastrophic failures, unplanned downtime, and costly repairs. The Bently Nevada 330103-00-07-10-02-CN 3300 XL 8 mm Proximity Probe provides the accurate, reliable displacement measurement needed to protect your turbomachinery, compressors, and pumps. This metric probe is engineered for harsh industrial environments, offering a linear range from 0.25 to 2.3 mm (10 to 90 mils) with a recommended gap setting of -9 Vdc for radial vibration monitoring.

Compatibility & Integration

This probe is part of the 3300 XL series and is compatible with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems.
