Heavy-Duty Armored Probe Designed for Continuous Rotating Machinery Protection
The Bently Nevada 330102-00-10-20-01-00 3300 XL 8 mm Proximity Probe is a rugged eddy current displacement sensor developed for accurate, non-contact measurement of shaft vibration, radial displacement, and axial position in critical rotating equipment. Built as part of the proven 3300 XL 8 mm Proximity Transducer System, this armored probe configuration provides enhanced mechanical protection while maintaining the high measurement stability required for machinery condition monitoring.
With a 3/8-24 UNF threaded design and armored cable construction, this model is configured with 0.0-inch unthreaded length, 1.0-inch overall case length, 2.0-meter total cable length, and a miniature coaxial ClickLoc™ connector with connector protector. The armored cable design improves resistance against abrasion, accidental impact, and harsh installation conditions, making it a preferred choice for demanding industrial applications.

Technical FAQs
1. What is the Bently Nevada 330102-00-10-20-01-00 used for?
It is used for measuring shaft vibration, radial movement, and axial position on rotating machinery using eddy current sensing technology.
2. What is the difference between 330101 and 330102 probes?
The 330101 series uses a standard non-armored cable design, while the 330102 series adds armored cable protection for installations exposed to mechanical stress or harsh environments.
3. What does the 330102 designation indicate?
The 330102 model number identifies a 3300 XL 8 mm proximity probe with 3/8-24 UNF thread and armored construction.
4. What does the "10" in the case length option mean?
The 10 option indicates a 1.0-inch overall case length.
5. What does the "20" cable option represent?
The 20 option specifies a 2.0-meter (6.6 ft) total probe cable length.
6. What type of connector does this probe use?
It uses a miniature coaxial ClickLoc™ connector with connector protector for secure signal transmission.
7. Does this model include hazardous-area certification?
This specific configuration uses the -00 approval option, meaning no additional agency approval option is selected. Other variants are available with CSA, ATEX, IECEx, or regional approvals.
8. What materials are used in the probe construction?
The probe tip is manufactured from polyphenylene sulfide (PPS), and the probe case uses AISI 303/304 stainless steel.
9. What components are needed to build a complete monitoring system?
A complete 3300 XL system normally includes the proximity probe, compatible extension cable, and a 3300 XL Proximitor Sensor.
10. Why choose an armored proximity probe?
Armored probes provide additional cable protection against abrasion, vibration, and accidental damage, improving reliability in industrial installations.
