Product Overview
The Bently Nevada 330105-XX-XX-10-02-05 (part number 157310-09) is a reverse-mount 8 mm proximity probe, part of the 3300 XL series. It works with a Proximitor sensor and extension cable to deliver high-precision measurements for static and dynamic shaft position and vibration. Designed for reverse mounting, this probe is suitable for applications where forward mounting is impractical.
