Bently Nevada 330106-05-30-10-00 3300 XL 8 mm Reverse Mount Proximity Probe

Description

The 330106-05-30-10-00 is a 3300 XL 8 mm reverse mount proximity probe, part of the Bently Nevada 3300 XL 8 mm Proximity Transducer System. This configuration features a 0.5 in unthreaded length (Option 05) and a 3.0 in case length (Option 30), designed for reverse mounting applications where the probe is installed through the machine case or a bracket, with the tip extending into the bearing housing or case interior.

This transducer is designed for use within the 3300 XL monitoring chain, typically pairing with a 3300 XL Proximitor sensor and extension cable. The system provides precise, non-contact displacement measurements for shaft vibration and axial position monitoring in critical rotating machinery, such as gas turbines, steam turbines, and centrifugal compressors. The reverse mount design simplifies installation in constrained spaces where external mounting is not feasible.

Features

• M10 x 1 thread configuration for reverse mounting installation
• 8 mm probe diameter compatible with 3300 XL Proximitor sensors
• Option 05: 0.5 in unthreaded length for standardized mounting thickness
• Option 30: 3.0 in overall case length
• Option 10: 1.0 m total system length
• Designed for non-contact, eddy-current measurement of shaft position and vibration
• Compatible with standard 3300 XL extension cables and monitoring systems

Applications

The 330106 reverse mount probe is utilized in heavy industrial environments for critical machinery protection. Typical applications include:

• Radial vibration measurement on centrifugal pumps and compressors
• Axial position (thrust) monitoring on steam and gas turbines
• Rotor position measurement in large electric motors and generators
• Machinery diagnostics where reverse-mount geometry is required by the housing layout

Installation Guidelines

Ensure the probe is mounted using the correct M10 x 1 threading to prevent damage to the probe case or the machine housing. Use the appropriate mounting bracket to secure the probe, ensuring it is electrically isolated if required by the application. Always verify the probe gap during installation to ensure it falls within the linear range of the Proximitor sensor (typically 1.27 mm or 50 mils). Proper cable routing should be maintained to avoid signal interference, and connectors should be protected using the provided connector protectors in exposed environments.
