Bently Nevada 330709 Series Technical Notes

The Bently Nevada 330709 series is a family of industrial proximity probes engineered for continuous, non-contact vibration and position measurement in rotating machinery. Deployed across petrochemical refineries, nuclear power stations, offshore platforms, LNG terminals, and heavy industrial compressor trains, the 330709 series forms a critical sensing layer within Bently Nevada's 3300 XL and System 1 condition monitoring architectures. These probes operate on the eddy-current principle, generating a high-frequency electromagnetic field that responds to changes in the distance between the probe tip and a conductive target surface. The resulting voltage signal is processed by a compatible proximitor/extension cable system to deliver real-time shaft displacement, eccentricity, and axial position data to the control room. The 330709 series is fully compatible with the Bently Nevada 3300 XL 8mm Proximity Transducer System and meets API 670 machinery protection standards, making it the reference-grade sensor for turbomachinery OEM and aftermarket applications globally.
