Bently Nevada 330104‑00‑11‑10‑02‑05
Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)
1. Product Introduction
The 330104‑00‑11‑10‑02‑05 is a high‑precision industrial proximity probe designed for non‑contact measurement of rotating machinery vibration and shaft displacement. It belongs to the 3300 XL 8 mm series, a widely implemented line of eddy current proximity sensors used in condition monitoring and machinery protection systems around the world.
This probe uses the principle of eddy current induction to convert relative motion between a conductive target and the sensor tip into a highly stable electrical signal. Because it does not require physical contact with the rotating shaft, wear is minimized and long‑term reliability is achieved. The series is known for consistent performance in harsh industrial environments, including plants with high vibration, heat, moisture, and airborne contaminants.
The “11” in the model code identifies a configuration with enhanced sensitivity and linear response characteristics, suitable for applications where precise measurement of shaft dynamics is critical. The “10” indicates the measurement range of up to 10 mm, “02” designates the industrial connector type, and “05” indicates a standard 5 m cable length.
This proximity probe is typically installed on bearing housings, turbine frames, or compressor stands close to rotating shafts. It plays a central role in vibration and displacement monitoring systems that help maintenance engineers optimize machinery reliability and avoid unscheduled downtime.
