Introduction
The Bently Nevada 330103-00-08-05-02-00 3300 XL 8mm Proximity Probe is a high-accuracy eddy current sensor designed for continuous, non-contact measurement of shaft vibration, radial displacement, and axial position in rotating machinery. As part of the widely deployed 3300 XL series, it provides stable and repeatable signals even in harsh industrial environments where mechanical reliability and measurement precision are essential.
This configuration is commonly used in turbine, compressor, and pump protection systems where medium-to-extended cable routing is required while maintaining high signal integrity across the full monitoring chain.
