Technical FAQs
1. What is the Bently Nevada 330102-00-12-05-02-05 used for?
It is used to measure shaft vibration, displacement, and position on rotating equipment using non-contact eddy current technology.
2. What is the difference between 330101 and 330102 probes?
The 330101 series uses a non-armored cable design, while the 330102 series includes armored cable protection for improved mechanical durability.
3. What does the 330102 designation indicate?
The 330102 designation identifies a 3300 XL 8 mm proximity probe with 3/8-24 UNF thread and armored construction.
4. What does the "12" option specify?
The 12 option indicates the probe case length configuration of approximately 1.2 inches.
5. What does the "05" cable option represent?
The 05 option specifies a 0.5-meter (1.6 ft) total probe cable length.
6. What type of connector is installed?
This model uses a miniature coaxial ClickLoc™ connector with standard cable.
7. Is this probe suitable for hazardous locations?
Yes. The -05 approval option provides CSA, ATEX, and IECEx approvals for compatible hazardous-area installations.
