The Bently Nevada 330703-000-040-90-01-CN is a 3300 XL 11 mm proximity probe designed for non-contact measurement of shaft vibration, radial position, eccentricity, and mechanical displacement in rotating machinery. It is widely used in steam turbines, gas turbines, compressors, pumps, generators, and other critical industrial equipment requiring continuous condition monitoring and protection.
As part of the 3300 XL 11 mm proximity transducer system, this probe provides high linearity, stable signal output, and strong resistance to vibration, oil, moisture, and electromagnetic interference. This configuration includes a 9.0 m integral cable, a Miniature ClickLoc connector with connector protector, standard industrial cable, and CN (China NEPSI hazardous-area approval) for regulated installations.
