Product Overview
The Bently Nevada 330196‑05‑30‑10‑CN 3300 XL 8 mm ETR Reverse Mount Probe is a specialized non‑contact displacement sensor designed for advanced machinery vibration and position monitoring. As part of the 3300 XL Proximity Transducer System, this reverse‑mount probe delivers precise measurement of shaft motion in applications where standard probe orientations are impractical.
Featuring an 8 mm sensing tip and engineered for “ETR” (End‑To‑Rear) mounting configurations, this probe excels in installations with limited access or confined spaces within machinery housings. Its rugged construction and eddy‑current technology ensure reliable performance in high‑vibration environments encountered in power generation, petrochemical, and heavy industrial facilities.

It measures vibration, displacement, and shaft position using non‑contact eddy‑current sensing.
3. What is the probe diameter?
The probe has an 8 mm sensing tip.
4. What is the linear measurement range?
The typical calibrated range is approximately 2 mm.
5. What environments is it suitable for?
It works reliably under industrial temperature, vibration, and moisture conditions.
6. What type of cable does it use?
FEP‑insulated coaxial cable for stable signal integrity.
7. What industries use this probe?
Power generation, petrochemical, oil & gas, and heavy manufacturing sectors.
8. Is this compatible with standard 3300 XL systems?
Yes, it interfaces with 3300 XL Proximitor sensors and monitoring systems.
9. Does the reverse mount design affect signal quality?
No, the measurement performance remains consistent with conventional probe orientations.
10. Can this probe be calibrated in the field?
Calibration is typically performed during initial system commissioning.
