Bently Nevada 330103-00-03-90-12-CN 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-03-90-12-CN are listed below for quick reference:

Industry Applications

Typical applications include:

• Steam and Gas Turbines: Measuring radial shaft vibration and axial position to detect imbalance, misalignment, or bearing wear.
• Centrifugal Compressors: Monitoring shaft displacement to prevent rubs and seal damage in high-speed trains.
• Large Pumps and Motors: Providing early warning of bearing degradation through continuous proximity measurement.

Installation & Setup Guidance

For optimal performance, mount the probe with the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils from the target). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. The maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Ensure the probe case thread engagement does not exceed 15 mm to avoid mechanical interference.

Maintenance & Reliability

The probe's PPS tip and stainless steel case provide robust resistance to harsh environments. The probe is designed to seal differential pressure between tip and case using a Viton O-ring. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Inspect the cable and connector periodically for signs of wear or fluid ingress, especially in high-moisture areas.

Solving Vibration Monitoring Challenges in Rotating Machinery

In high-speed rotating equipment like steam turbines and centrifugal compressors, undetected shaft vibration can lead to catastrophic failure. The Bently Nevada 330103-00-03-90-12-CN 3300 XL 8 mm Proximity Probe provides the precise, reliable measurement needed to prevent unplanned downtime. This metric probe, with a 9.0-meter FluidLoc cable and miniature coaxial ClickLoc connector, delivers accurate displacement data directly to your monitoring system.

Compatibility & Integration

This 3300 XL probe works with Bently Nevada 3300 XL Proximitor Sensors and compatible monitoring systems. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators to achieve Class I, Zone 0 ratings. For non-incendive circuits, follow drawing 140979.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify total cable length and connector type match your system requirements. The 330103-00-03-90-12-CN is available now at AutoDCSTech. Contact our team for assistance with configuration or to confirm lifecycle status before ordering.
