Bently Nevada 330104-00-06-05-02-00 3300 XL 8 mm Proximity Probe, Metric

When Vibration Monitoring Demands Precision

Unplanned downtime in rotating machinery often starts with undetected shaft vibration. The Bently Nevada 330104-00-06-05-02-00 3300 XL 8 mm proximity probe provides the accurate displacement measurement needed to catch issues early. This metric probe, with its M10x1 thread and armored construction, is engineered for harsh industrial environments where reliability is non-negotiable.

Technical Specifications Breakdown

The 330104-00-06-05-02-00 delivers a 2 mm (80 mils) linear range, starting at approximately 0.25 mm (10 mils) from the target. Its nominal DC resistance measures 7.45 ± 0.50 Ω for the 0.5 m probe length. The recommended gap setting for radial vibration is -9 Vdc, roughly 1.27 mm (50 mils). Operating temperature spans -52°C to +177°C for the standard probe, with extended range options available for the tip and cable. The probe case material is AISI 303 or 304 stainless steel, and the tip is made of polyphenylene sulfide (PPS).

Industry Applications

This proximity probe excels in monitoring radial vibration and axial position of turbines, compressors, pumps, and motors. In a typical steam turbine installation, the 330104-00-06-05-02-00 provides the -9 Vdc gap setting to track shaft movement within the 2 mm linear range. Its PPS tip withstands high temperatures and aggressive media, making it suitable for refinery and chemical plant applications where seal integrity is critical.

Installation & Setup Guidance

Proper installation begins with verifying the probe case thread engagement—maximum 15 mm for the M10x1 thread. Use the recommended torque of 11.2 N·m (100 in·lbf) to avoid damaging the seal. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the proximitor sensor and monitor. For best frequency response, keep wiring as short as practical.

Maintenance & Reliability

To maintain measurement accuracy, inspect the probe tip and cable for physical damage regularly. The Viton® O-ring provides a differential pressure seal, but probes are not pressure tested before shipment. If your application requires a pressure seal test, contact the custom design department. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure. The probe's relative humidity tolerance keeps ASF change under 3% when tested per IEC 68-2-3 at 93% humidity for up to 56 days.

Selection Guide & Purchasing Advice

Before ordering the 330104-00-06-05-02-00, confirm your system requires a 3300 XL 8 mm metric probe with M10x1 thread and 0.5 m cable. This model uses a miniature coaxial ClickLoc connector with standard cable. For intrinsically safe installations, refer to drawing 141092 for zener barriers or galvanic isolators. For non-incendive circuits, use drawing 140979. Verify the probe length and connector type match your existing setup.
