Bently Nevada 330102-00-28-10-02-05 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330102-00-28-10-02-05 are listed below for quick reference:

Installation and Setup Guidance

Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned conductors. Maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For high-frequency applications, refer to the frequency response graphs (Figures 10 and 12) to assess signal roll-off with longer wiring. The probe case thread is 3/8-24 UNF with a maximum thread engagement of 0.563 in. Ensure the probe is not exposed to temperatures below -34°C (-30°F) to avoid premature pressure seal failure.

Maintenance and Reliability

The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel, providing corrosion resistance in demanding environments. The probe exhibits less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC standard 68-2-3 for up to 56 days. Regular inspection of the cable and connector for damage is recommended. For applications requiring pressure seal verification, contact the custom design department.

Precision Vibration Monitoring for Critical Machinery

Rotating machinery failures often begin with undetected shaft vibration. The Bently Nevada 330102-00-28-10-02-05 3300 XL 8 mm Proximity Probe provides the accurate, non-contact measurement needed to catch these issues early. This probe is engineered for continuous operation in harsh industrial environments, delivering reliable data for predictive maintenance and machine protection.

Solving Vibration Monitoring Challenges

Traditional contact sensors wear out and introduce measurement errors. This proximity probe eliminates physical contact, providing a linear range of 2 mm (80 mils) starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc [approximately 1.27 mm (50 mils)], ensuring consistent, repeatable readings.

Compatibility and Integration

This probe is part of the 3300 XL series and is designed for use with Bently Nevada Proximitor sensors. The 1.0 meter probe length is compatible with the standard Proximitor sensor. Note that 3-meter probes are only available on 330101 probes and are designed for use with the 9 meter Proximitor sensor; 5-meter probes require the 5 meter Proximitor sensor. The miniature coaxial ClickLoc connector ensures a secure, quick connection.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the required cable length, connector type, and agency approvals. The 330102-00-28-10-02-05 includes CSA, ATEX, and IECEx approvals, making it suitable for hazardous area installations. Contact AutoDCSTech for availability and lifecycle status before ordering.
