Bently Nevada 330103-17-22-10-12-05 — Detailed Technical Overview

1. Product Introduction

The Bently Nevada 330103-17-22-10-12-05 is a high-precision 8 mm proximity probe designed for non-contact measurement of shaft vibration and displacement in rotating machinery. It is part of the 3300 XL series, a mature and widely used platform in industrial condition monitoring and machine protection systems.

This model features an extended probe body (code 17), making it suitable for installations that require deeper mounting or extended reach. The configuration “22-10-12-05” defines the probe length, case structure, cable length, connector type, and certification level.

Using eddy current sensing technology, the probe provides accurate and stable measurements without physical contact, ensuring long-term reliability and minimal wear. It is typically used together with extension cables and signal conditioning modules to form a complete monitoring system.
