Product Overview
The Bently Nevada 330101-00-55-20-12-05 3300 XL 8 mm Proximity Probe is a precision eddy-current proximity probe designed for the 3300 XL 8 mm Proximity Transducer System. It provides accurate, non-contact measurement of shaft vibration and shaft position for continuous monitoring of critical rotating machinery.
This configuration includes a 5.5 in. (139.7 mm) probe case length, a 2.0 m (6.6 ft) FluidLoc® integrated cable, a Miniature ClickLoc™ coaxial connector, and CSA, ATEX, and IECEx hazardous-area approvals (Option 05). The FluidLoc® cable is engineered to help prevent fluid migration through the cable, improving long-term reliability in harsh industrial environments.
