Product Overview
When process compressors demand reliable vibration monitoring, the Bently Nevada 330905-00-10-05-02-05 3300 NSv Proximity Probe delivers precision and durability. This industrial automation module is part of the 3300 NSv series, designed for non-contact shaft vibration and position measurement. The probe features an M10X1 thread, a 0.5-meter total length, and a miniature coaxial ClickLoc connector with standard cable. It is mechanically and electrically interchangeable with the previous 3300 RAM probe, while offering increased chemical resistance for demanding applications. The side-view characteristics are superior to the 3000-series 190 probe when gapping at the same distance from the target.

Industry Applications
The 330905-00-10-05-02-05 excels in process compressor applications where chemical resistance is critical. Use it for radial vibration and axial position monitoring on rotating machinery such as turbines, pumps, and compressors. In a typical setup, the probe targets a shaft with a minimum diameter of 8.9 mm (0.35 in) for flat targets; for axial measurements on shafts smaller than 13 mm (0.5 in), expect a scale factor change. Reducing the gap helps limit the change. This probe's superior side-view characteristics make it ideal for tight installations where space is limited.
Installation & Setup Guidance
Proper installation ensures accurate readings. Follow these guidelines:
-
Thread torque: For M10X1 probe cases, maximum rated torque is 22.6 N•m (200 in•lb) on the first three threads; recommended torque is 7.5 N•m (66 in•lb). Finger tight is the recommended torque for the probe tip.
-
Field wiring: Use a three-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) conductors, or 0.25 to 0.75 mm² (18 to 23 AWG) with ferrules. Maximum length between the Proximitor Sensor and monitor is 305 meters (1,000 feet).
-
Bend radius: Minimum bend radius is 25.4 mm (1.0 in) with or without SST armor.
-
Gap setting: Set the recommended gap to 1.0 mm (40 mils) for optimal linearity.
Maintenance & Reliability
Routine inspection of the probe cable and connector is essential. The probe case is AISI 304 stainless steel, providing corrosion resistance. The probe tip is PPS, offering chemical resistance. The sealing material is a Viton O-ring, designed to seal differential pressure between the tip and case. Note that probes are not pressure tested prior to shipment; if your application requires a pressure seal test, contact the custom design department. Operating temperature range is -52°C to +177°C, suitable for harsh environments.
Compatibility & Integration
The 330905-00-10-05-02-05 is compatible with Bently Nevada's 3300 XL NSv Proximitor Sensor and monitor systems. It is mechanically and electrically interchangeable with the 3300 RAM probe and extension cable. The miniature coaxial ClickLoc connector ensures secure connection. For integration, ensure the extension cable's dc resistance and capacitance match the system requirements to maintain signal integrity.
Buying Guide
When purchasing the 330905-00-10-05-02-05, verify the total length (0.5 meter), unthreaded length (00 mm), overall case length (100 mm), and connector type (miniature coaxial ClickLoc). Check the agency approval option (-05 multiple approvals). This unit is new and original in factory packing with a 12-month warranty.
