Bently Nevada 330104-01-05-50-02-CN 3300 XL 8 mm Proximity Probe

Precision Vibration Monitoring for Critical Machinery

When unplanned downtime strikes rotating equipment, the Bently Nevada 330104-01-05-50-02-CN 3300 XL 8 mm Proximity Probe provides the reliable shaft displacement and vibration data needed to diagnose issues early. This probe is designed for permanent installation in harsh industrial environments, delivering consistent performance under demanding conditions.

Technical Specifications Breakdown

The 330104-01-05-50-02-CN features a probe tip made of polyphenylene sulfide (PPS) and a case constructed from AISI 303 or 304 stainless steel (SST). The unthreaded length is 10 mm, overall case length is 50 mm, and total length is 5.0 meters (16.4 feet). It uses a miniature coaxial ClickLoc connector with standard cable. Nominal probe DC resistance from center conductor to outer conductor is 8.73 ± 0.50 Ω for the 5.0 meter probe. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring.

Industry Applications

In power generation, a sudden increase in bearing vibration can signal impending failure. The 330104-01-05-50-02-CN mounts directly into the machine casing using its M10 x 1 thread, providing real-time gap voltage and dynamic vibration signals to a compatible 3300 XL Proximitor Sensor. This allows operators to trend changes and schedule maintenance before catastrophic damage occurs. Similarly, in oil and gas facilities, the probe's stainless steel case and PPS tip resist corrosion and wear in harsh environments.

Installation & Setup Guidance

Mount the probe using the M10 x 1 threaded section. Ensure the probe tip is properly gapped at 1.27 mm (50 mils) for optimal linear range. Use only 3300 XL 8 mm extension cables and Proximitor Sensors to maintain system accuracy. The probe accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe and extension cable. Power requirement is -17.5 Vdc to -26 Vdc when installed with nonincendive circuit per drawing 140979 at 12 mA maximum consumption.

Maintenance & Reliability

Periodically inspect the probe cable and connector for damage. The Viton O-ring seal helps maintain pressure integrity. Verify that the probe tip is free of debris and that the target surface (AISI 4140 steel recommended) is clean. Regular calibration checks with a 3300 XL system ensure measurement accuracy.

Selection Guide & Purchasing Advice

Before ordering, confirm that the 330104-01-05-50-02-CN matches your required thread size (M10 x 1), cable length (5.0 m), and connector type (miniature coaxial ClickLoc). Ensure your Proximitor Sensor and extension cable are 3300 XL 8 mm compatible. For current availability and lifecycle status, contact plcmatrix.com, a trusted supplier of Bently Nevada components.
