Bently Nevada 330104-00-06-10-02-CN 3300 XL 8 mm Proximity Probe, Metric

Solving Vibration Monitoring Challenges in Rotating Machinery

When a critical turbine or compressor begins to exhibit unexpected shaft vibration, the ability to accurately measure displacement becomes paramount. The Bently Nevada 330104-00-06-10-02-CN 3300 XL 8 mm Proximity Probe provides the precise, reliable data needed to protect your machinery and avoid costly unplanned downtime. This probe is engineered for continuous operation in demanding environments, delivering consistent performance where it matters most.

Technical Specifications Breakdown

The 330104-00-06-10-02-CN is a metric 3300 XL 8 mm proximity probe designed for radial vibration and position measurement. Key specifications include:

Probe Tip Material: Polyphenylene sulfide (PPS) for durability and chemical resistance.

Probe Case Material: AISI 303 or 304 stainless steel (SST) for corrosion resistance.

Thread Size: M10x1, with a maximum thread engagement of 15 mm.

Linear Range: 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target.

Recommended Gap Setting: -9 Vdc [approximately 1.27 mm (50 mils)] for radial vibration.

Cable Length: 1.0 meter (3.3 feet) with a miniature coaxial ClickLoc connector.

Temperature Range (Standard): -52°C to +177°C (-62°F to +350°F) for the probe.

Nominal Probe DC Resistance: 7.59 ± 0.50 Ω at 1.0 m length.

These parameters ensure the probe delivers accurate, repeatable measurements in a wide range of operating conditions.

Industry Applications

This probe is ideally suited for critical rotating machinery such as steam turbines, gas turbines, centrifugal compressors, and large pumps. In a typical application, the 330104-00-06-10-02-CN mounts into a machine case to monitor shaft radial vibration. Its 2 mm linear range provides ample coverage for most vibration excursions, while the PPS tip withstands high temperatures and aggressive media. The M10x1 thread allows straightforward installation into standard probe mounting holes.

Installation & Setup Guidance

Proper installation is essential for accurate readings. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. The maximum cable length between the probe and the monitor is 305 meters (1,000 feet). For radial vibration, set the initial gap to approximately -9 Vdc, which corresponds to about 1.27 mm (50 mils) from the target. Ensure the probe tip is clean and free of debris before installation. The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring.

Maintenance & Reliability

Routine inspection of the probe and cable is recommended to verify mechanical integrity and electrical continuity. The probe operates reliably within its specified temperature range and relative humidity conditions (less than 3% change in Average Scale Factor when tested at 93% humidity per IEC 68-2-3). Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. For extended temperature range applications, the probe tip can withstand up to +218°C (+425°F) and the cable up to +260°C (+500°F).

Compatibility & Integration

The 330104-00-06-10-02-CN is designed for use with Bently Nevada 3300 XL Proximitor sensors and compatible monitoring systems. When installed with intrinsically safe zener barriers or galvanic isolators, the probe meets Class I, Zone 0 and Class 1, Division 1 hazardous area requirements. For non-incendive installations, it meets Class I, Zone 2 and Class 1, Division 2. Always consult the appropriate wiring diagrams (e.g., drawing 141092 or 140979) for your specific installation.

Selection Guide & Purchasing Advice
