Bently Nevada 330901‑00‑24‑10‑11‑05 3300 XL NSv Proximity Probe

The Bently Nevada 330901‑00‑24‑10‑11‑05, part of the 3300 XL NSv series, is a miniature proximity probe designed for restricted clearance applications and small shaft vibration monitoring. It is widely used in compressors, pumps, and other rotating machinery where standard 5 mm or 8 mm probes cannot fit.

Part Number Breakdown

Key Applications

• Compressors: Centrifugal air, refrigeration, and process gas compressors.

• Restricted Clearances: Areas where side‑view or counterbore limits prevent use of standard probes.

• Small Targets: Radial vibration measurement on shafts under 51 mm (2 inches).

Functional Description

The 330901‑00‑24‑10‑11‑05 probe uses eddy‑current technology to measure shaft displacement and vibration. Its compact design allows installation in tight spaces, while the FluidLoc cable prevents fluid ingress, ensuring long‑term reliability. The probe delivers a linear signal compatible with Bently Nevada monitoring systems, enabling accurate diagnostics of machine health.

Frequently Asked Questions

• What makes the NSv probe different from standard probes?  It is designed for narrow side‑view (NSv) applications, fitting into restricted clearances where larger probes cannot be installed.

• Can this probe be used on small shafts?  Yes, it is optimized for shafts under 51 mm (2 inches).

• What is the advantage of the FluidLoc cable?  It prevents leakage and contamination through the cable, maintaining signal integrity in harsh environments.

Field Installation Guidelines

• Mounting: Use the 1/4‑28 UNF thread; ensure proper torque to avoid probe damage.

• Cable Routing: Keep the FluidLoc cable away from high‑voltage lines to minimize interference.

• Shielding: Ground shielding at the Proximitor end only to prevent ground loops.

• Verification: Confirm linear range calibration during commissioning.

• Maintenance: Inspect connectors and cable integrity periodically, especially in compressor environments.
