Product Overview
The Bently Nevada 330904-00-10-05-11-05 is a 3300 NSv Proximity Probe designed for reliable vibration and position measurement in critical rotating machinery. This model features an M8X1 threaded case with armor, a 0.5-meter FluidLoc cable, and a miniature coaxial ClickLoc connector. It delivers precise, repeatable measurements with a linear range of 1.5 mm (60 mils) and an incremental scale factor of 7.87 V/mm (200 mV/mil).
Engineered for harsh industrial environments, the 330904-00-10-05-11-05 offers enhanced chemical resistance compared to previous 3300 RAM probes, making it ideal for process compressor applications. Its side-view characteristics outperform the 3000-series 190 probe, ensuring accurate gapping at the same distance from the target.

Compatibility & Integration
The 330904-00-10-05-11-05 is mechanically and electrically interchangeable with Bently Nevada's previous 3300 RAM probe and extension cable. It works seamlessly with the 3300 XL NSv Proximitor Sensor, supporting field wiring up to 305 meters (1,000 feet) with a three-conductor shielded triad cable. This probe is suitable for use with Bently Nevada monitoring systems that accept 3300 NSv inputs.
Installation & Setup
For optimal performance, mount the probe with the recommended torque of finger tight (maximum 0.56 N•m). Ensure the target surface meets the minimum diameter requirements. When measuring axial positions on shafts smaller than 13 mm (0.5 in), reduce the gap to minimize scale factor changes. Use the recommended 1.0 mm (40 mils) gap setting for standard applications.
Maintenance & Reliability
The probe's stainless steel case and PPS tip resist chemical attack, reducing maintenance needs. The Viton O-ring seals differential pressure between tip and case. Regularly inspect the cable and connector for damage, and avoid bending beyond the 25.4 mm radius. These practices extend service life and maintain measurement accuracy.
Selection Guide & Purchasing Advice
When ordering, verify the part number 330904-00-10-05-11-05 to ensure you receive the M8X1 thread, 0.5 m cable, and multiple approvals. Confirm compatibility with your existing monitor and extension cable. For reliable sourcing, PLC Source PRO offers this authentic Bently Nevada probe with factory warranty and original packaging.
