Introduction
The Bently Nevada 330106-05-03-10-02-CN is a 3300 XL 8 mm Reverse Mount Probe intended for non-contact measurement of shaft movement in critical rotating machinery. The 330106 family is associated with the 3300 XL 8 mm reverse-mount platform, providing a practical sensing solution for applications where conventional probe access is restricted by bearing housings, machine casings, or other mechanical structures.
This configuration combines a 1.0-meter cable option, Miniature ClickLoc coaxial connection, and a CN agency-approval configuration. The 1-meter cable is particularly convenient for installations where the probe and associated signal-conditioning equipment are positioned relatively close together, while still allowing additional system cable length to be accommodated where required.
Designed for professional vibration and machinery-monitoring applications, the probe can be used as part of a properly engineered 3300 XL proximity transducer system. It is a strong choice for maintenance teams seeking a compact, reliable reverse-mount sensing solution for turbines, compressors, generators, pumps, and other rotating assets.

Applications
Steam Turbine Monitoring
The probe can be incorporated into turbine shaft-monitoring systems where continuous measurement of shaft movement is required. Its reverse-mount arrangement provides useful installation flexibility around bearing housings and other restricted areas.
Gas Turbine Machinery
Gas turbine rotors operate under demanding mechanical and thermal conditions. A correctly configured proximity system can monitor shaft behavior and provide valuable information for machinery protection and condition assessment.
Compressor Applications
Large compressors often contain crowded bearing structures where conventional probe installation is difficult. The reverse-mount design allows engineers to approach the target from an alternative direction.
Generator Shaft Monitoring
Generators can benefit from continuous shaft vibration and position measurement. The 330106 platform can be integrated into suitable monitoring systems for observing rotor behavior during normal and changing operating conditions.
Pumps and Motors
Critical pumps, motors, fans, and auxiliary rotating machines can use proximity measurement as part of a predictive-maintenance strategy. Non-contact sensing is particularly useful on high-speed rotating equipment.
Fluid-Film Bearing Systems
Shaft displacement relative to a stationary bearing surface is an important condition indicator in fluid-film bearing machinery. A properly installed proximity probe can continuously monitor this relationship.
Machinery Protection
When paired with compatible 3300 XL signal-conditioning hardware, the probe can form part of a machinery protection channel designed to detect abnormal shaft vibration or position.
Replacement and Retrofit Work
The 330106-05-03-10-02-CN is a useful reference when maintaining an existing 3300 XL reverse-mount installation that specifically calls for the corresponding mechanical, cable, connector, and approval configuration.
Advantages
Purpose-Built Reverse Mounting
The reverse-mount construction is the primary installation advantage. It gives engineers more freedom when the sensing location cannot be conveniently reached using a standard forward-mounted probe.
1-Meter Cable Reach
The 1.0-meter integral cable provides approximately 3.3 feet of connection distance. This is a versatile length for compact machinery installations where a 0.5-meter cable may be too short but a substantially longer cable is unnecessary.
Miniature ClickLoc Interface
The 02 connector configuration uses a Miniature ClickLoc coaxial connector, providing a compact interface suited to the 3300 XL proximity-system architecture.
Non-Contact Sensing
Eddy-current proximity technology measures shaft movement without physical contact. The absence of mechanical contact helps eliminate probe-tip wear associated with direct-contact measurement.
Compact 8 mm Format
The 8 mm probe platform offers a useful balance between sensing capability and installation size. It is well suited to common shaft vibration and position monitoring applications.
Flexible Cable Architecture
A 1-meter probe cable provides enough integral reach for many installations while still allowing an appropriate extension cable to be added where the total system length requires it.
Industrial Construction
The 3300 XL proximity-probe platform is designed for demanding rotating-equipment environments. Its robust construction supports continuous service when the probe is installed within its specified operating conditions.
Broad Machinery Coverage
The same basic proximity technology can be applied across turbines, compressors, generators, pumps, motors, and other rotating assets, making the 330106 family useful for facilities with diverse machinery fleets.
Maintenance Efficiency
Using the correct complete part number during replacement helps maintenance personnel preserve the existing mechanical arrangement and reduce unnecessary changes to probe mounting or cable routing.
Technical FAQs
1. What is the Bently Nevada 330106-05-03-10-02-CN?
It is a 3300 XL 8 mm Reverse Mount Probe designed for non-contact shaft vibration and position measurement.
2. How long is the cable?
The 10 option identifies a 1.0-meter cable, approximately 3.3 feet, in the 3300 XL reverse-mount configuration.
3. What connector is used?
The 02 option specifies a Miniature ClickLoc coaxial connector.
4. What does “8 mm” mean?
The 8 mm designation identifies the probe family and nominal sensing-tip size used for the 3300 XL 8 mm proximity transducer system.
5. Is the 330106 designed for reverse mounting?
Yes. The 330106 family is identified as a 3300 XL 8 mm Reverse Mount Probe family.
6. What measurement principle does it use?
The probe uses eddy-current proximity sensing, allowing non-contact measurement of the relative position of a conductive shaft target.
7. What is the approximate probe weight?
The probe is generally in the 0.3 kg class. Actual shipping weight is higher and depends on packaging and associated items.
8. Can the 1-meter probe be used with an extension cable?
Yes, provided the complete 3300 XL proximity system is configured with the correct total electrical length. The probe and extension cable should be considered together with the compatible Proximitor Sensor.
9. Is the CN version interchangeable with a 00 version?
It should not be assumed to be interchangeable. The approval/configuration suffix is part of the complete ordering specification. Where certification or installation requirements apply, the exact suffix should be retained.
10. What should be checked before ordering a replacement?
Confirm the complete 330106-05-03-10-02-CN part number, probe mounting geometry, cable length, connector, target gap, system electrical length, and applicable approval requirements. Matching only the 8 mm designation is not sufficient for a reliable replacement decision.
