Bently Nevada 330105-02-12-20-12-05 3300 XL 8 mm Reverse Mount Probe

Description

The 330105-02-12-20-12-05 is a 3300 XL 8 mm reverse mount proximity probe designed for non-contact eddy-current displacement measurement in critical machinery monitoring applications. This specific configuration features a 3/8-24 UNF threaded body, a 2.0 meter total system length (Option 20), and utilizes a FluidLoc cable (Option 12) with a miniature ClickLoc coaxial connector (Option 12). It is intended for use within 3300 XL 8 mm transducer chains, providing reliable shaft vibration and axial position data for turbines, compressors, and other rotating equipment.

This reverse mount probe configuration is optimized for installations where the probe is mounted from the inside of the machine case, pointing toward the shaft. The inclusion of the FluidLoc cable (Option 12) provides enhanced protection against oil migration, making it suitable for environments where exposure to lubricating fluids is a concern. The 05 approval code certifies this component for hazardous area operation, including CSA, ATEX, and IECEx standards.

Features

• 330105 Configuration: 3/8-24 UNF threaded, reverse mount 8 mm proximity probe.
• FluidLoc Cable (Option 12): Designed to prevent oil leakage through the cable path, offering superior fluid containment.
• Connector Type: Miniature coaxial ClickLoc connector for secure, reliable signal transmission without the need for additional connector protectors.
• System Length: 2.0 meter total length (Option 20) ensures compatibility with standard 3300 XL monitoring chain requirements.
• Hazardous Area Approval (Option 05): Certified for CSA, ATEX, and IECEx environments.

Applications

• Turbine shaft vibration and axial position monitoring
• Compressor rotor position and displacement tracking
• Critical rotating machinery protection
• Hazardous area installations requiring CSA, ATEX, or IECEx compliance
• High-reliability oil-lubricated machinery environments
