Product Overview
The Bently Nevada 330905-05-10-10-01-00 is a 3300 NSv proximity probe engineered for reliable vibration and position monitoring in critical rotating machinery. This industrial automation module delivers precise, non-contact measurements even in harsh process environments. With a 1.0 meter total length, M10×1 thread, and miniature coaxial ClickLoc connector, the 330905-05-10-10-01-00 integrates seamlessly into existing 3300 XL monitoring systems.
Compared to earlier 3300 RAM probes, the NSv design offers superior chemical resistance and improved side-view characteristics, making it ideal for process compressor applications. The probe and extension cable remain mechanically and electrically interchangeable with the previous generation, simplifying upgrades and spare part management.

Real-World Applications
The 330905-05-10-10-01-00 excels in monitoring shaft vibration, axial position, and eccentricity in turbomachinery, compressors, and large electric motors. Its enhanced chemical resistance allows direct installation in process compressor applications where exposure to aggressive media is common.
For critical machinery protection, the probe pairs with a 3300 XL Proximitor Sensor and monitor, delivering accurate gap measurements over a 1.5 mm linear range. The side-view performance surpasses that of the older 3000-series 190 probe, ensuring reliable readings even when the probe is offset from the target.
The stainless steel case and PPS tip withstand extreme temperatures from -52°C to +177°C, making the 330905-05-10-10-01-00 suitable for both high-temperature turbine applications and low-temperature cryogenic processes.
Installation & Setup Guidance
For optimal performance, mount the Bently Nevada 330905-05-10-10-01-00 with the recommended gap of 1.0 mm (40 mils). Use the provided ClickLoc connector to attach the extension cable securely. Apply only finger tight torque when threading the probe into the mounting boss, and never exceed the maximum torque of 0.56 N•m (5 in•lb).
Field wiring should use three-conductor shielded triad cable with conductors sized 0.2 to 1.5 mm² (16 to 24 AWG). If ferrules are used, 0.25 to 0.75 mm² (18 to 23 AWG) is preferred. Keep the total field wiring length between the probe and the monitor to a maximum of 305 meters (1,000 feet). For longer runs, review the frequency response graphs to understand signal rolloff at high frequencies.
When measuring axial position on shafts smaller than 13 mm (0.5 in) diameter, expect a change in scale factor. Reduce the gap between probe and target to minimize this effect.
Maintenance & Reliability
The robust construction of the 330905-05-10-10-01-00 minimizes maintenance needs, but periodic inspection is recommended. Check the probe tip for contamination or damage, and verify that the connector remains clean and securely fastened.
The probe is designed to seal differential pressure between the tip and case using a Viton O-ring. Note that probes are not pressure tested prior to shipment; if your application requires a pressure seal test, contact the custom design department.
With a wide operating temperature range and corrosion-resistant materials, this industrial automation module delivers long service life, reducing downtime and replacement costs.
Compatibility & Integration
The 330905-05-10-10-01-00 is mechanically and electrically compatible with the Bently Nevada 3300 XL Proximitor Sensor and the 3300 XL monitoring system. It is also interchangeable with the previous 3300 RAM probe and extension cable, allowing direct replacement in existing installations.
The miniature coaxial ClickLoc connector ensures a secure, repeatable connection with the extension cable, maintaining signal integrity over the full frequency range.
