The Bently Nevada 330105-02-12-10-02-00 is a high-performance 8 mm reverse mount proximity probe from the 3300 XL series, designed for precision vibration and position monitoring in critical rotating machinery . Part of the 3300 XL eddy-current transducer system, this probe provides non-contact displacement measurement for turbines, compressors, pumps, and other fluid-film bearing machines . Fully compliant with API 670 Standard (4th Edition) , it supports complete interchangeability of probes, extension cables, and Proximitor sensors without requiring individual component calibration. The reverse mount design allows installation in confined spaces where standard probes cannot be accommodated.
