The Bently Nevada 330704-000-050-10-02-CN is an 11 mm proximity probe from the 3300 XL series, designed for non-contact measurement of shaft vibration and displacement in rotating machinery.
It is part of the eddy current proximity transducer system and operates together with a Proximitor sensor and extension cable to provide continuous monitoring of rotor dynamics in turbines, compressors, pumps, and generators.
This specific configuration is the “CN” approval variant, typically indicating China regional certification / hazardous area compliance (CN marking option) within the 3300 XL ordering structure.
The 050 case length option (50 mm) combined with the 10 (1.0 m system length) and 02 (ClickLoc connector type) defines a standard short-body probe with modular cable assembly used in industrial monitoring applications.

System Configuration
This probe is used as part of a complete 3300 XL measurement chain:
- 3300 XL 11 mm proximity probe
- Matching extension cable
- 3300 XL Proximitor sensor
The system converts shaft motion into a proportional electrical signal used for vibration monitoring, diagnostics, and machinery protection functions.
