Compact Metric Proximity Sensor for Accurate Shaft Position and Vibration Monitoring
The Bently Nevada 330103-00-02-05-02-00 3300 XL 8 mm Proximity Probe (Metric) is a precision non-contact displacement sensor designed for reliable monitoring of rotating machinery. Utilizing advanced eddy current sensing technology, this probe provides accurate measurement of shaft vibration, radial displacement, and axial position in critical industrial equipment. As part of the 3300 XL 8 mm Proximity Transducer System, it delivers proven performance for machinery protection and condition monitoring applications.
Designed with an M10 × 1 metric thread and unarmored construction, the 330103 series provides a flexible solution for installations requiring metric mounting compatibility. The 330103-00-02-05-02-00 configuration features a 0 mm unthreaded length, 20 mm overall case length, 0.5-meter cable, miniature coaxial ClickLoc™ connector with standard cable, and no additional agency approval option. This compact design is ideal for applications where installation space is limited while maintaining the measurement reliability of the 3300 XL platform.

Technical FAQs
1. What is the Bently Nevada 330103-00-02-05-02-00 used for?
It is used to measure shaft vibration, radial displacement, and axial position on rotating machinery through non-contact sensing technology.
2. What makes this model different from 330101 and 330102 probes?
The 330103 series uses an M10 × 1 metric thread and unarmored construction, while 330101 uses a 3/8-24 UNF thread without armor and 330102 uses a 3/8-24 UNF armored design.
3. What sensing technology does this probe use?
It uses eddy current technology to detect changes in the distance between the probe tip and a conductive shaft surface.
4. What does the "00" unthreaded length option mean?
The 00 option indicates a 0 mm unthreaded length configuration.
5. What does the "02" case length option specify?
The 02 option represents a 20 mm overall case length.
6. What does the "05" cable option indicate?
The 05 option specifies a 0.5-meter (1.6 ft) total cable length.
7. What connector is used on this proximity probe?
This model uses a miniature coaxial ClickLoc™ connector with standard cable.
8. Does this model include hazardous-area approvals?
No. The -00 suffix indicates that no additional agency approval option is selected.
9. What components are needed to build a complete 3300 XL system?
A complete system typically includes the proximity probe, compatible extension cable, and a 3300 XL Proximitor Sensor.
10. Why choose the 3300 XL 8 mm metric probe series?
The metric series provides accurate displacement measurement with international mounting compatibility and reliable performance for critical rotating machinery.
