Product Overview

The Bently Nevada 330905-00-09-05-02-05 is a specialized proximity probe belonging to the 3300 NSv (Narrow Sideview) series. This transducer system is specifically engineered for applications where conventional proximity probes cannot be used due to restricted installation space or small target diameters. The NSv series is the primary solution for monitoring vibration and displacement on shafts smaller than 51 mm (2 inches) or in environments where the probe must be mounted in close proximity to adjacent metal surfaces that would typically cause "side-view" interference.

This non-contact sensor utilizes eddy current technology to provide high-resolution data for radial vibration, axial thrust position, and Keyphasor signals. It is a critical component for Turbine Supervisory Instrumentation (TSI) in compact centrifugal compressors, pumps, and small-scale steam turbines.

Key Technical Characteristics

The 3300 NSv system offers unique advantages for high-density machinery layouts, providing the same level of reliability as the standard 3300 XL series but in a more versatile form factor.

• Optimized for Small Shafts: Designed to maintain linear signal integrity on shaft diameters where standard 8mm probes experience significant "cross-talk" or distorted magnetic fields.

• Reduced Side-view Sensitivity: The probe tip and internal coil are configured to minimize the influence of surrounding conductive material, allowing for installation in tighter counterbores.

• Rugged Environmental Build: With an IP67 ingress protection rating, the probe is fully sealed against the penetration of industrial lubricants, moisture, and dust.

• Precision Signal Output: Delivers a linear voltage output proportional to the gap between the probe tip and the target, ensuring accurate real-time feedback for machinery protection systems.

• Thermal Endurance: Engineered to operate within a temperature range of -40°C to +85°C, ensuring stable calibration during the thermal expansion cycles of rotating machinery.
