The Bently Nevada 330704-000-030-50-02-00 is an 11 mm proximity probe belonging to the 3300 XL proximity transducer system, designed for non-contact measurement of shaft vibration and displacement in rotating machinery.
It is used in combination with a Proximitor sensor and extension cable to form a complete eddy current-based measurement chain. This system is widely applied in machinery protection and condition monitoring for turbines, compressors, pumps, and other critical rotating assets.
According to 3300 XL system specifications, the 11 mm probe family provides a typical linear measurement range of around 4 mm (160 mil) for accurate vibration and position monitoring in industrial applications.
The 030–50 configuration indicates a short case length with a 5.0 m cable assembly, making it suitable for compact installations requiring standard reach and flexible routing.
