FAQ

Q: What is this probe used for?
A: It’s used to measure shaft radial position and vibration on rotating machinery. The probe tip responds to changes in gap between the probe and target (shaft),

which is translated by the Proximitor sensor into displacement/vibration signals.

Q: What does “8 mm” signify?
A: It refers to the nominal diameter of the probe tip — a common size for industrial probes, offering a balance of sensitivity and

robustness in applications where 5 mm is too small.

Q: Is it compatible with other Bently Nevada parts?
A: Yes. 3300 XL probes are backwards-compatible and interchangeable with other 3300 series

components (e.g., extension cables and Proximitor sensors).
