The Bently Nevada 330104-00-11-50-02-05 proximity probe is a high-reliability eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, radial displacement, and rotor position in critical rotating machinery.

Built on the proven 3300 XL 8 mm platform, this configuration is widely used in turbine systems, compressors, generators, and other heavy-duty rotating equipment where measurement stability and long-distance signal transmission are essential for safe and efficient operation.

The “50” system length configuration (5.0 m class) provides strong installation flexibility in large industrial plants, especially where monitoring systems are located remotely from the machine skid. The “02-05” connector/approval combination typically aligns with ClickLoc-style connection architecture and regionally certified industrial deployment requirements.
