Product Introduction
The Bently Nevada 330106-05-30-05-02-05 is a 3300 XL 8 mm reverse mount proximity probe designed for non-contact measurement of shaft vibration and position in rotating machinery. It uses eddy-current sensing technology to monitor the gap between the probe tip and a conductive target, making it well suited to machinery protection and condition-monitoring applications.
With its reverse-mount configuration, 8 mm probe diameter, M10 × 1 mounting thread, 0.5 m total length option, and Miniature ClickLoc coaxial connector, this model is intended for installations where conventional probe mounting is not practical. The PPS probe tip and stainless-steel probe case provide a durable construction for demanding industrial environments.
The 330106-05-30-05-02-05 also incorporates the 3300 XL design approach, including TipLoc construction at the probe tip and secure cable attachment. For maintenance teams, this combination provides a practical balance of installation flexibility, measurement consistency, and long-term serviceability.

Applications
The 330106-05-30-05-02-05 is particularly valuable in rotating-equipment monitoring systems where accurate shaft movement information is essential.
Turbine Monitoring
The probe can be integrated into monitoring arrangements for steam and gas turbines, helping detect shaft vibration and displacement before abnormal mechanical conditions develop.
Compressor Protection
For centrifugal and other rotating compressors, continuous shaft-position and vibration measurements can support machinery protection and predictive maintenance programs.
Pump and Bearing Monitoring
The 8 mm eddy-current sensing design is suitable for monitoring rotating shafts associated with fluid-film bearing machinery, where small changes in shaft position can provide important condition information.
Gearbox and Rotating Equipment
The probe can also be applied to gearboxes and other high-speed machinery where non-contact displacement measurement is preferred.
Machinery Protection Systems
When paired with the appropriate 3300 XL Proximitor sensor and monitoring electronics, the probe becomes part of a complete machinery protection chain for vibration and position monitoring.
Key Advantages
Reverse-Mount Flexibility
The reverse-mount construction provides an alternative installation arrangement for applications with limited front-side access or restricted mounting space.
Reliable Non-Contact Measurement
Eddy-current technology allows the probe to monitor shaft movement without physical contact between the sensing tip and the rotating target.
Rugged Industrial Construction
The PPS probe tip and stainless-steel case are designed for demanding industrial service, providing a robust mechanical package for continuous monitoring applications.
Secure Probe Construction
The 3300 XL design incorporates TipLoc technology to reinforce the connection between the probe tip and probe body. CableLoc technology also helps provide a secure connection between the cable and probe assembly.
Easy System Integration
The Miniature ClickLoc coaxial connector provides a practical connection method for integration with compatible 3300 XL system components.
Maintenance-Oriented Design
A standardized 3300 XL configuration makes the probe a convenient replacement choice for maintenance teams working with established Bently Nevada machinery monitoring installations.
