High-Performance Armored Shaft Monitoring Probe for Critical Machinery Reliability
The Bently Nevada 330102-03-28-10-02-00 3300 XL 8 mm Proximity Probe is a precision eddy current displacement sensor designed for continuous monitoring of rotating machinery shaft vibration, radial displacement, and axial position. Built within the proven 3300 XL 8 mm Proximity Transducer System, this armored probe delivers dependable measurement accuracy, excellent mechanical durability, and long-term stability for industrial condition monitoring applications.
The 330102 series is the armored version of the standard 3300 XL 8 mm proximity probe family. This configuration features a 3/8-24 UNF-2A threaded body, 0.3-inch unthreaded length, 2.8-inch overall case length, 1.0-meter cable, and a miniature coaxial ClickLoc™ connector with connector protector. The armored cable design provides improved protection against abrasion, vibration, and installation-related mechanical stress, making it suitable for demanding machinery environments.

Technical FAQs
1. What is the Bently Nevada 330102-03-28-10-02-00 used for?
It is used for measuring shaft vibration, radial displacement, and axial position on rotating machinery through eddy current sensing technology.
2. What does the 330102 series indicate?
The 330102 series identifies a 3300 XL 8 mm proximity probe with armored cable construction and 3/8-24 UNF threading.
3. What is the difference between 330101 and 330102 probes?
The 330101 series uses a standard non-armored cable, while the 330102 series provides armored cable protection for harsher industrial environments.
4. What does the "03" option represent?
The 03 option indicates a 0.3-inch unthreaded length configuration.
5. What does the "28" option specify?
The 28 option indicates a 2.8-inch overall case length configuration.
6. What does the "10" cable option mean?
The 10 option specifies a 1.0-meter (3.3 ft) total probe cable length.
7. What type of connector is installed on this probe?
This model uses a miniature coaxial ClickLoc™ connector with connector protector.
8. Does this model include hazardous-area certification?
The -00 suffix indicates that no additional agency approval option is selected. Models with -05 are available with CSA, ATEX, and IECEx approvals.
9. What additional components are needed for operation?
A complete system normally requires a compatible extension cable and a 3300 XL Proximitor Sensor.
10. Why choose an armored proximity probe?
Armored probes provide additional cable protection in locations exposed to vibration, abrasion, maintenance activity, and mechanical impact.
