Description
Overview
The 330704‑010‑060‑10‑11‑00 proximity probe is part of Bently Nevada’s 3300 XL 11 mm transducer family, designed for high‑accuracy displacement and vibration measurement in large rotating machinery. This probe assembly is optimized for applications requiring extended linear range and enhanced sensitivity, making it suitable for turbines, compressors, and other fluid‑film bearing equipment.
Design and Construction
This model features an M14×1.5 threaded probe body with a 60 mm overall length and a minimum 10 mm unthreaded section. The probe includes a 1‑meter armored cable for mechanical protection in harsh environments. Its 11 mm tip design provides a wider linear range than 8 mm probes, enabling more accurate monitoring of slow‑speed or high‑displacement machinery.
The assembly incorporates FluidLoc cable technology to prevent oil ingress and uses a miniature coaxial ClickLoc connector for secure, tool‑free installation. Stainless steel armor (indicated by “10” in the part number) ensures long‑term durability in high‑vibration environments.
