The Bently Nevada 330106-05-30-05-02-RU is a 3300 XL 8 mm Reverse Mount Probe designed for non-contact monitoring of shaft position, vibration, and movement in rotating machinery. Its reverse-mount configuration provides an installation alternative for machines where a conventional probe orientation is difficult to accommodate.
Built around eddy-current proximity sensing, the probe is intended to provide stable measurement information for machinery condition monitoring and protection applications. The 8 mm sensing format makes it a practical fit for established 3300 XL monitoring arrangements, while its stainless-steel construction supports demanding industrial service.
With a total length of 0.5 meter and a product weight of approximately 0.161 kg, the 330106-05-30-05-02-RU combines a relatively compact physical profile with the installation flexibility required for specialized machinery layouts. It can be considered for turbines, compressors, pumps, generators, and other critical rotating equipment where reliable shaft monitoring is an important part of maintenance strategy.

Applications
Power Generation Equipment
The probe can be used in turbine and generator monitoring systems where shaft movement and vibration are important indicators of rotating-equipment condition. Continuous displacement information can help operators identify changes that warrant further inspection.
Oil and Gas Machinery
Compressors, pumps, and other critical rotating assets in oil and gas facilities can benefit from non-contact shaft monitoring. The reverse-mount design is particularly useful when access around the machine casing is limited.
Petrochemical and Chemical Plants
Continuous vibration and displacement monitoring is valuable for machinery operating in process environments where unexpected equipment downtime can have a significant operational impact.
Industrial Manufacturing
The 330106-05-30-05-02-RU can support monitoring of critical rotating machinery used in production environments, helping maintenance teams track equipment behavior and respond to abnormal conditions.
Water and Wastewater Systems
Pump and motor assemblies can use proximity-based shaft monitoring as part of a broader machinery protection or predictive maintenance program.
Specialized Machinery Installations
The reverse mounting arrangement makes this model a useful option for applications where the available installation direction differs from a conventional proximity probe arrangement.
Advantages
Reverse-Mount Installation Flexibility
The key advantage of this model is its reverse-mount configuration. It provides engineers with another installation approach when machine geometry, access limitations, or existing mounting arrangements make standard installation impractical.
Non-Contact Shaft Measurement
The proximity sensing principle allows shaft movement to be measured without direct contact between the probe and rotating component. This makes the technology well suited to high-speed machinery monitoring.
8 mm Probe Format
The 8 mm configuration offers a practical sensing format for many rotating-equipment applications and is designed around the 3300 XL monitoring ecosystem.
Rugged Stainless-Steel Housing
A stainless-steel housing provides a durable mechanical enclosure for industrial service and helps the probe withstand the physical demands associated with machinery monitoring installations.
Wide Temperature Capability
With a listed operating range of -40°C to +121°C, the probe is suited to a broad range of industrial operating environments.
Stable Monitoring for Maintenance Programs
Reliable shaft-position and vibration information can contribute to condition-based maintenance strategies, giving maintenance personnel useful data for identifying changes in machine behavior.
Lightweight Physical Design
At approximately 0.161 kg, the listed assembly is relatively lightweight, which can make handling and replacement more convenient during field maintenance.
Practical Integration
The probe is designed for use within Bently Nevada 3300 XL monitoring arrangements, making it a practical component for installations already built around this product family.
