Description
Overview
The Bently Nevada 330104‑02‑21‑10‑01‑00 proximity probe is an 8 mm eddy‑current sensor designed for high‑accuracy vibration and shaft displacement monitoring in critical rotating machinery. As part of the 3300 XL transducer family, it provides stable linearity, robust mechanical construction, and seamless compatibility with XL Proximitor Sensors and extension cables.
Design and Construction
This configuration features an armored M10 × 1 threaded probe with a 20 mm minimum unthreaded length and a 210 mm case length, making it suitable for installations requiring extended reach or deeper mounting sleeves. The probe includes a 1.0 m integral cable terminated with a miniature ClickLoc coaxial connector for secure, repeatable electrical connections.
The armored design enhances mechanical protection in harsh industrial environments, while the XL system architecture provides improved RFI/EMI immunity—allowing installation in fiberglass housings or electrically noisy areas without performance degradation.
