Bently Nevada 330103-00-08-10-02-CN 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-08-10-02-CN are listed below for quick reference:

Application in Rotating Machinery Protection

This 8 mm proximity probe is engineered for radial vibration and position measurement in critical assets. The 2 mm linear range (0.25 to 2.3 mm from target) provides the sensitivity needed for early fault detection. The PPS tip withstands high temperatures and chemical exposure, making it suitable for steam turbines and gas compressors. The M10x1 thread allows direct mounting into standard probe holders.

Installation and Setup Guidance

Proper installation ensures measurement accuracy. The probe requires a 3-conductor shielded triad cable for field wiring (0.2 to 1.5 mm² / 16 to 24 AWG). Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Use tinned field wiring for reliable connections. The recommended gap setting for radial vibration is -9 Vdc, corresponding to approximately 1.27 mm (50 mils). Ensure thread engagement does not exceed 15 mm to avoid mechanical interference.

Maintenance and Reliability

The probe is designed for long-term reliability in industrial environments. The Viton® O-ring provides a differential pressure seal between tip and case. Exposing the probe to temperatures below –34°C (–30°F) may cause premature seal failure. Inspect the probe and cable periodically for physical damage. The stainless steel case resists corrosion, and the PPS tip maintains dimensional stability across the temperature range.

Precision Vibration Monitoring for Critical Machinery

Industrial rotating machinery demands accurate, reliable vibration measurement to prevent unplanned downtime. The Bently Nevada 330103-00-08-10-02-CN 3300 XL 8 mm Proximity Probe delivers the performance needed for continuous protection of turbines, compressors, and pumps. This metric probe features a polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, ensuring durability in harsh environments.

Compatibility and Integration

The 330103-00-08-10-02-CN is part of the 3300 XL family and works with compatible Bently Nevada Proximitor Sensors and monitoring systems. For intrinsically safe installations, use zener barriers per drawing 141092 or galvanic isolators (Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga). For non-incendive circuits, use connections per drawing 140979 (Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc).

Selection Guide and Purchasing Advice

When selecting a replacement probe, verify the thread size (M10x1), overall length, and cable length match your application. The 330103-00-08-10-02-CN is a metric probe with 1.0m cable and ClickLoc connector. Contact AutoDCSTech for availability and lifecycle status before ordering. Our team can help confirm compatibility with your existing monitoring system.

Troubleshooting and Common Issues

If the probe output is erratic, check the field wiring connections and ensure the cable length does not exceed 305 meters. Verify the gap setting is within the linear range (0.25 to 2.3 mm). If the probe is exposed to high humidity, confirm the average scale factor change is less than 3%. For pressure seal concerns, contact the custom design department for testing options.
