Description
Overview
The Bently Nevada 330709‑00‑05‑10‑12‑05 proximity probe is an 11 mm eddy‑current sensor engineered for long‑range, high‑accuracy vibration and displacement measurement on large rotating machinery. As part of the 3300 XL series, it offers enhanced mechanical durability, fluid‑resistant construction, and full compatibility with XL Proximitor Sensors, making it suitable for demanding industrial environments.
Design and Construction
This probe features an M16 × 1.5 threaded body with a minimum 50 mm case length, providing a robust mechanical interface for heavy‑duty installations. It includes a 1.0 m FluidLoc cable, designed to prevent fluid migration along the cable jacket—an essential feature for turbines, compressors, and oil‑rich machinery.
The probe incorporates Bently Nevada’s patented TipLoc molding process, which permanently bonds the probe tip to the body, and CableLoc reinforcement, providing up to 330 N (75 lbf) of pull strength. These design elements significantly reduce the risk of mechanical failure in high‑vibration environments.
A miniature ClickLoc coaxial connector ensures secure, repeatable electrical connections without requiring tools.

Functional Description
The 330709‑00‑05‑10‑12‑05 probe provides a wide linear measurement range due to its 11 mm tip diameter, making it suitable for large‑shaft machinery and applications requiring extended displacement capability. When paired with the 3300 XL Proximitor Sensor, it delivers high‑resolution vibration and position data with excellent immunity to electrical noise.
The FluidLoc cable prevents oil ingress—a common failure mode in rotating equipment—while the TipLoc and CableLoc technologies ensure long‑term mechanical stability. These features make the probe ideal for high‑value assets where reliability and measurement accuracy are critical.
Application Areas
-
Steam and gas turbines
-
Large compressors and expanders
-
High‑vibration rotating equipment
-
Oil‑rich or contamination‑prone environments
-
Machinery requiring extended linear measurement range
FAQ
Q: What advantages does the 11 mm probe offer over 8 mm models It provides a longer linear range, making it ideal for large‑shaft or high‑clearance applications.
