Description
Overview
The Bently Nevada 330101‑00‑59‑15‑12‑05 proximity probe is an 8 mm eddy‑current sensor designed for high‑accuracy shaft vibration and displacement measurement in rotating machinery. As part of the 3300 XL transducer family, it provides stable linearity, long‑term reliability, and full compatibility with both XL and non‑XL 3300‑series components.
Design and Construction
This probe features a 3/8‑24 UNF threaded body with a 5.9‑inch overall case length, offering a durable mechanical structure suitable for harsh industrial environments. It includes a 2.0 m FluidLoc cable, engineered to prevent oil migration along the cable jacket—an essential requirement for turbines, compressors, and other oil‑rich installations.
A miniature ClickLoc coaxial connector ensures secure, repeatable electrical connections while allowing quick installation and removal without tools.
The probe carries CSA, ATEX, and IECEx certifications, supporting deployment in hazardous‑area applications.

Functional Description
The 330101‑00‑59‑15‑12‑05 probe forms the sensing element of the 3300 XL system, generating a voltage proportional to the distance between the probe tip and the monitored conductive surface. When paired with an XL Proximitor Sensor and extension cable, it provides high‑resolution vibration and displacement measurements with excellent immunity to electromagnetic interference.
The FluidLoc cable design prevents oil ingress, significantly improving long‑term reliability in turbine and compressor environments. Full interchangeability with other 5 mm and 8 mm 3300‑series components simplifies system upgrades and maintenance.
