The Bently Nevada 330708-00-20-50-02-00 is a 3300 XL 11 mm Proximitor® Sensor designed for use as part of the 3300 XL 11 mm Transducer System. When used together with the corresponding 3300 XL 11 mm Proximity Probe and Extension Cable, it forms a complete transducer system for machinery condition monitoring and proximity measurement.

The 3300 XL 11 mm Proximitor® Sensor is specifically designed to replace the earlier 7200-series 11 mm and 14 mm Transducer Systems. This provides a standardized upgrade path for users transitioning from legacy 7200-series installations to the 3300 XL 11 mm platform.

When upgrading from a 7200-series Transducer System to the 3300 XL 11 mm Transducer System, every component of the transducer system must be replaced with 3300 XL 11 mm components, including the Proximity Probe, Extension Cable, and Proximitor® Sensor. Replacing the complete transducer system ensures compatibility among all system components.
