The Bently Nevada 330905-00-10-10-02-00 is a high-precision 3300 NSv (Narrow Side View) proximity probe engineered for machinery with severe spatial constraints. Unlike standard proximity sensors, the NSv series is specifically designed for applications where the probe must be installed in tight gaps or near metallic surfaces that would normally cause signal interference. This transducer provides critical non-contact displacement data, allowing for the continuous monitoring of shaft vibration and axial position in small centrifugal compressors, high-speed pumps, and various aero-derivative turbines.
