The Bently Nevada 330703-000-060-50-12-00 Proximity Probe is a high-precision 11 mm eddy current displacement sensor designed for continuous monitoring of shaft vibration, radial position, and mechanical clearance in rotating machinery.

As part of the Bently Nevada 3300 XL proximity transducer system, this model is engineered for demanding industrial environments where signal stability, EMI resistance, and long-term reliability are essential. The 060 configuration provides a 60 mm probe case length, making it suitable for deeper installation positions and mechanically constrained assemblies.

The 50-12-00 configuration typically represents an extended system cable option combined with a Miniature ClickLoc connector and standard agency approval, making it a flexible choice for large rotating equipment installations such as turbines and compressors.
