Bently Nevada 330704-00-05-10-02-CN 3300 XL 11 mm Armored Proximity Probe

Product Overview

Bently Nevada 330704-00-05-10-02-CN is a 3300 XL 11 mm armored proximity probe designed for shaft vibration and position monitoring in turbines, compressors, generators, and heavy industrial rotating machinery. It operates within the Bently Nevada 3300 XL eddy-current system and delivers stable displacement signals in harsh mechanical and electrical environments.

This probe is built for applications requiring enhanced mechanical protection through armored cable construction. It is commonly deployed in refineries, power plants, and offshore installations where vibration, oil exposure, and mechanical abrasion are continuous operating conditions.

The M14 x 1.5 threaded interface provides secure installation and stable alignment under high vibration loads, ensuring long-term measurement consistency in critical machinery protection systems.
