Bently Nevada 330101-08-20-10-02-00 3300 XL 8mm Proximity Probes

Product Introduction

The Bently Nevada 330101-08-20-10-02-00 3300 XL 8mm Proximity Probe is a high-performance eddy current sensor designed for precise non-contact measurement of shaft displacement and vibration in rotating machinery. As part of the well-established 3300 XL series, this probe is widely recognized for its reliability, accuracy, and compatibility with industrial monitoring systems.

This probe is engineered to deliver stable and repeatable measurements in demanding environments. With a total length of 1.0 meter, it provides flexibility for installation in a wide range of machinery configurations while maintaining signal integrity. It is typically used together with extension cables and proximitor sensors to form a complete proximity transducer system.

The 3300 XL 8mm probe is optimized for use in critical applications where continuous monitoring of shaft position, radial vibration, and axial displacement is essential. Its rugged construction and high sensitivity make it suitable for long-term operation in harsh industrial conditions, including high temperature, oil contamination, and vibration-heavy environments.
