Bently Nevada 330903-00-04-10-02-05 3300 XL NSv Proximity Probe

Description

330903-00-04-10-02-05 is a 3300 XL NSv 5 mm proximity probe configured with 0.0 in unthreaded length (Option 00), 0.4 in case length (Option 04), 1.0 m total length (Option 10), a Miniature ClickLoc connector (Option 02), and CSA, ATEX, and IECEx hazardous area approvals (Option 05). This probe is a component of the 3300 XL NSv Proximity Transducer System, specifically engineered for machinery applications where the target area is insufficient for standard 8 mm or 11 mm probes, such as aeroderivative turbines and small-bore rotating equipment.

The 3300 XL NSv system maintains compatibility with existing Bently Nevada monitoring hardware while providing the required signal integrity for reduced target geometry. The 5 mm tip configuration allows for installation in tight clearances, ensuring accurate shaft vibration and axial position measurement where traditional transducers may suffer from side-view interference. This configuration uses a standard Miniature ClickLoc connector, requiring mating with compatible 330930 series extension cables to complete the transducer loop.

Installation Guidelines

Ensure the probe is installed in a rigid mount to prevent mechanical vibration unrelated to the shaft. Maintain correct gap settings as specified in the 3300 XL NSv manual for the specific target material. When using the Miniature ClickLoc connector, ensure it is fully seated to prevent intermittent signal loss. Routing of extension cables should be isolated from high-voltage power lines to minimize EMI, using conduit where mechanical protection is required.

Compliance and Certifications

This unit is certified for hazardous area environments under Option 05, including CSA, ATEX, and IECEx compliance. Verify site-specific requirements before installation in classified areas.
