330101-00-12-10-02-05 | Bently Nevada| 8 mm Proximity Probe

Product Description

The Bently Nevada 330101-00-12-10-02-05 is an 8 mm proximity probe from the 3300 XL platform, engineered for accurate non-contact measurement of shaft vibration and static or dynamic position in rotating machinery. It is designed to operate as part of a complete 3300 XL transducer system together with a compatible extension cable and Proximitor® sensor.

This probe uses a compact stainless-steel housing with a 3/8-24 UNF mounting thread, making it suitable for installations where space is limited but measurement stability and long-term reliability are critical. Integrated TipLoc® and CableLoc® technologies improve mechanical robustness, reduce installation damage risk, and ensure consistent electrical performance over the probe’s service life.

The probe output is optimized for linear response within the standard 3300 XL operating gap range, supporting high-resolution vibration and displacement measurements required for machinery protection and condition monitoring systems.

FAQ

Is this probe interchangeable with 5 mm or 11 mm probes?

No. The 8 mm probe must be used with 3300 XL components designed specifically for the 8 mm system to maintain correct scale factor and linear range.

Does this probe include agency approvals?

Yes. The “05” option code indicates inclusion of applicable agency approvals when installed as part of an approved system.

Can this probe be used for axial position measurement?

Yes. When properly installed and paired with the correct Proximitor® sensor, it supports axial position, thrust, and vibration measurements.
