Bently Nevada 330103-00-04-50-02-00 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-04-50-02-00 are listed below for quick reference:

Industry Applications

In a typical power generation application, the 330103-00-04-50-02-00 provides early warning of shaft misalignment or bearing wear, enabling predictive maintenance that avoids unplanned downtime. The 2 mm linear range and precise -9 Vdc gap setting ensure accurate measurement over the full operating envelope.

Installation & Setup Guidance

Proper installation is critical for reliable performance. The probe must be mounted using the M10 x 1 thread with a maximum thread engagement of 15 mm. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. The maximum distance between the Proximitor sensor and the monitor is 305 meters (1,000 feet). Always verify the probe DC resistance (8.73 ± 0.50 Ω) before final assembly to confirm cable integrity.

Maintenance & Reliability

The 330103-00-04-50-02-00 is designed for long-term, maintenance-free operation in most environments. However, periodic inspection of the cable and connector for physical damage is recommended. The probe can operate in relative humidity up to 93% (per IEC 68-2-3) with less than 3% change in Average Scale Factor. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.

Precision Vibration Monitoring with the Bently Nevada 330103-00-04-50-02-00

Industrial rotating machinery demands reliable, accurate vibration sensing to prevent catastrophic failures. The Bently Nevada 330103-00-04-50-02-00 is a 3300 XL 8 mm proximity probe designed for continuous, non-contact measurement of shaft displacement and vibration. This metric probe features an M10 x 1 thread, a 40 mm overall case length, and a 5.0 meter (16.4 feet) total length cable terminated with a miniature coaxial ClickLoc connector. It is intended for use exclusively with a 5 meter Proximitor sensor to ensure optimal signal integrity.

The probe tip is made of polyphenylene sulfide (PPS), offering chemical resistance and thermal stability. The probe case is constructed from AISI 303 or 304 stainless steel, providing durability in harsh industrial environments. The 330103-00-04-50-02-00 is designed to seal differential pressure between the probe tip and case using a Viton O-ring, though it is not pressure tested prior to shipment.

Compatibility & Integration

This probe is part of the Bently Nevada 3300 XL series and is specifically designed for use with a 5 meter Proximitor sensor. It supports installation with intrinsic safety barriers (per drawing 141092) for Class I, Zone 0 hazardous areas, or with non-incendive circuits (per drawing 140979) for Class I, Zone 2 locations. The miniature coaxial ClickLoc connector simplifies field replacement without special tools.

Selection Guide & Purchasing Advice

When selecting a replacement or new proximity probe, verify the thread size, cable length, and connector type match your existing installation. The 330103-00-04-50-02-00 is a metric M10 x 1 probe with a 5.0 m cable and ClickLoc connector.
