Product Overview
The Bently Nevada 330905-02-10-05-02-00 is a 3300 NSv proximity probe designed for reliable vibration and position monitoring in industrial rotating machinery. This Industrial Automation Module delivers precise measurement data to help prevent unplanned downtime in critical applications such as compressors, turbines, and pumps.
With a 0.5-meter total length and a miniature coaxial ClickLoc connector, the 330905-02-10-05-02-00 integrates easily into existing monitoring systems. Its enhanced chemical resistance makes it suitable for process compressor environments where standard probes may fail.

Key Features & Benefits
-
Chemical Resistance: The NSv probe's increased chemical resistance vs. the 3300 RAM probe expands its use in process compressor applications.
-
Interchangeable: Mechanically and electrically compatible with previous 3300 RAM probes and extension cables.
-
Superior Side-View Performance: Improved side-view characteristics compared to 3000-series 190 probes.
-
Field Wiring Flexibility: Supports 0.2 to 1.5 mm² (16 to 24 AWG) wire, with up to 305 meters (1,000 feet) of cable between the Proximitor Sensor and monitor.
Industry Applications
The 330905-02-10-05-02-00 excels in monitoring shaft vibration and axial position in critical rotating equipment. Typical applications include:
-
Process Compressors: The enhanced chemical resistance protects the probe in harsh media environments.
-
Steam and Gas Turbines: Accurate vibration monitoring helps prevent catastrophic failures.
-
Pumps and Motors: Reliable position sensing ensures stable operation and extended service life.
Installation & Setup
For optimal performance, mount the probe with the recommended gap setting of 1.0 mm (40 mils). Use finger-tight torque initially, and do not exceed 0.56 N•m (5 in•lb) for the probe case. Ensure the target surface meets the minimum size requirements: at least 8.9 mm (0.35 in) diameter for flat targets, with 13 mm (0.5 in) recommended for consistent scale factor.
When routing field wiring, use a three-conductor shielded triad cable. Keep the total cable length between the Proximitor Sensor and the monitor within 305 meters (1,000 feet) to maintain signal integrity.
Maintenance & Reliability
Regularly inspect the probe tip for contamination or damage. The PPS tip and stainless steel case resist many chemicals, but verify compatibility with your specific process media. Periodically check the connector torque to ensure a secure connection. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring; if pressure testing is required for your application, contact the custom design department.
Selection Guide
When selecting a replacement probe, verify the total length, thread size, and connector type. The 330905-02-10-05-02-00 includes a 0.5-meter cable and M10x1 thread. For different cable lengths or armored versions, consider other configurations in the 3300 NSv series.
