Bently Nevada 330905-00-08-05-12-00 | 3300 NSv Proximity Probe

8 mm NSv Probe for Narrow Sideview Installations

The Bently Nevada 330905-00-08-05-12-00 belongs to the 3300 NSv series and performs non-contact vibration measurements. This sensor monitors shaft displacement in tight clearance areas of turbines and compressors. Its slim profile allows installation where standard probes cannot physically fit.

This probe features an 8 mm tip with a 12 mm diameter case for narrow sideview access. A matched Proximitor sensor completes the system for accurate shaft relative vibration data. The device includes an integral cable with a miniature coaxial connector at the system end.
