The Bently Nevada 330703-000-040-10-11-00 is a 3300 XL 11 mm Proximity Probe engineered for high-precision, non-contact measurement of shaft vibration, shaft position, eccentricity, and mechanical displacement in rotating machinery. It is widely used in turbines, compressors, pumps, generators, and other critical equipment requiring continuous condition monitoring and machinery protection.

As part of the 3300 XL 11 mm Proximity Transducer System, this probe delivers excellent linearity, reliable signal stability, and superior resistance to vibration, moisture, oil, and electromagnetic interference. The 11 connector option features a Miniature ClickLoc connector with FluidLoc cable, providing enhanced sealing performance for harsh industrial environments, while the 00 approval option indicates that no special agency certification is required.
