Description
Overview
The 330881-28-04-080-03-02 PROXPAC XL proximity transducer is a fully integrated measurement assembly developed by Bently Nevada for applications requiring robust, self‑contained vibration and displacement monitoring. Unlike traditional systems that rely on separate Proximitor enclosures and extension cables, this assembly incorporates the 3300 XL Proximitor sensor directly into the housing, creating a compact, high‑reliability solution for critical rotating machinery.
