Bently Nevada 330104-00-20-05-02-00 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330104-00-20-05-02-00 3300 XL 8 mm Proximity Probe is a high-performance sensor designed for non-contact vibration and position measurement in rotating machinery. As part of the globally trusted 3300 XL series, this proximity probe operates using eddy current technology to deliver precise, real-time monitoring of shaft position and dynamic behavior.

Matched with a compatible extension cable and Proximitor sensor, this probe provides an accurate linear output corresponding to shaft-to-probe distance, enabling machine protection systems to detect mechanical degradation — before it results in costly unplanned downtime.

Built to operate in demanding industrial environments, this particular model — with a 0.5 meter total length, armor cable, and standard 8 mm tip — is ideal for critical machinery in power generation, oil & gas, refining, chemical processing, and other industries where robust, reliable measurements are essential for equipment health monitoring and protection.

Product Specifications

Applications

The 330104-00-20-05-02-00 3300 XL 8 mm Proximity Probe is widely used across many industries for condition monitoring and protection of critical rotating machinery:
