The Bently Nevada 330104-00-10-90-02-00 proximity probe is a high-reliability eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, radial displacement, and rotor position in rotating machinery.

As part of the widely deployed 3300 XL 8 mm proximity transducer system, this model is engineered for heavy-duty industrial environments such as turbines, compressors, generators, and large mechanical drive systems. Its configuration is optimized for long-distance signal transmission, making it suitable for plants where monitoring equipment is installed far from the rotating asset.

The “90” system length configuration (commonly associated with extended cable designs) provides exceptional installation flexibility in large-scale industrial layouts while maintaining signal stability and measurement accuracy.
