Bently Nevada 330904-00-09-10-02-05 3300 XL NSv Proximity Probe

Description

The 330904-00-09-10-02-05 is a 3300 XL NSv proximity probe configuration featuring an M8x1 thread, integrated armor, and a 1.0 meter total system length. This eddy-current displacement probe is a critical component of the 3300 XL NSv Proximity Transducer System, specifically engineered for applications where space constraints or small target geometries limit the performance of standard transducers. This configuration includes Option 00 (0.0 inch unthreaded length), Option 09 (0.9 inch case length), Option 10 (1.0 meter total length), Option 02 (standard miniature ClickLoc connector), and Option 05 (CSA/ATEX/IECEx hazardous area approvals).

The 3300 XL NSv system is designed for high-precision monitoring on machinery such as small-bore turbomachinery, aeroderivative turbines, and equipment where shaft diameters are below 51 mm (2 inches). By utilizing a smaller probe tip and coil assembly, this transducer provides reliable radial vibration, axial position, and tachometer measurements in restricted areas, effectively replacing legacy 3300 RAM or 190-series transducer systems.

Features

• Thread: M8x1 thread for precise mechanical mounting.
• Armor: Integrated stainless steel armor for improved mechanical protection in industrial environments.
• Total Length: 1.0 meter system length (probe plus cable).
• Connector: Miniature coaxial ClickLoc connector (Option 02) for secure, reliable signal path.
• Approvals: Option 05 certification supporting CSA, ATEX, and IECEx hazardous area requirements.
• Compatibility: Designed for use with 3300 XL NSv Proximitor Sensors and extension cables.

Applications

• Radial vibration and radial position measurements on fluid-filmed bearing machines.
• Axial (thrust) position measurements for small-scale targets.
• Tachometer and zero speed measurements.
• Phase reference (Keyphasor) signaling.
• Monitoring in machines with tight side-view or counter-bore restrictions.

Installation Guidelines

Ensure the probe is mounted using the provided locknuts in a location that minimizes vibration of the mounting bracket itself. Verify that the probe tip gap is set to approximately 1.0 mm (40 mils) as recommended for nominal operation. When routing cables, avoid sharp bends and maintain separation from high-voltage AC lines to prevent signal interference. Use supplied connector protectors if the environment exposes connectors to moisture or debris.
