Bently Nevada 330101-00-47-05-02-05 3300 XL 8 mm Probe
An imperial-threaded 8 mm probe with a 4.7-inch case, short standard cable and multiple approvals.
Product Profile
330101-00-47-05-02-05 is a non-armored 3300 XL 8 mm probe with a 3/8-24 UNF body. It has no unthreaded length, a 4.7-inch overall case, 0.5 m total probe length and a ClickLoc connector without protector.
The 05 suffix identifies the multiple-approval execution. Correct replacement requires the exact case envelope and the extension-cable length that completes the installed 5 m or 9 m system.

System Role
- Provides a non-contact eddy-current signal for shaft vibration or position.
- Fits imperial 3/8-24 probe brackets and housings that match the 4.7-inch case.
- Forms the sensing end of a matched probe, extension cable and Proximitor Sensor chain.
- Carries the approval identity needed for controlled hazardous-area replacement.
Compatibility
- Do not substitute a nearby 4.6-, 5.0- or 5.2-inch case without checking insertion and adjustment range.
- Select the extension cable from the 0.5 m probe lead and installed Proximitor system length.
- Provide separate mechanical protection for the exposed connector because option 02 omits the protector.
- Confirm the complete approved loop and certificate revision before installation.
Applications
- Radial shaft vibration channels on fluid-film bearing machinery.
- Axial position and key measurement points within the 8 mm system range.
- Approved-area replacement where the original 3/8-24 mounting and short probe lead are retained.
FAQ
Why is the 4.7-inch case on 330101-00-47-05-02-05 important?
It controls insertion reach and adjustment range; a close catalog number can fit the thread yet leave the probe tip in the wrong position.
Which extension cable normally completes 330101-00-47-05-02-05?
Select the cable length needed to reach the exact installed system length after accounting for this 0.5 m probe lead.
How should the unprotected connector on 330101-00-47-05-02-05 be handled?
Keep it clean, dry, strain-free and inside suitable installation protection; do not force or tape over a contaminated joint.
Can the multiple-approval suffix on 330101-00-47-05-02-05 be accepted without paperwork?
No. Match the nameplate and certificate revision to the area classification, associated apparatus and installation drawing.
What comparison should follow replacement of 330101-00-47-05-02-05?
Compare gap voltage, slow-roll runout, phase, monitor scaling and running vibration with the pre-maintenance channel record.
