The Bently Nevada 330704-000-050-90-02-05 is an 11 mm proximity probe from the 3300 XL series, engineered 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. This system is widely used in turbines, compressors, pumps, and generators for continuous condition monitoring and machinery protection.
The 050 / 90 / 02 / 05 configuration generally represents:
- 050 = 50 mm case length
- 90 = 9.0 m system cable length
- 02 = ClickLoc miniature coaxial connector system
- 05 = Multiple approval / compliance variant (often used for broader industrial certification requirements)
The 3300 XL 11 mm probe family provides a typical linear measurement range of around 4 mm (160 mil), making it suitable for reliable shaft vibration monitoring in fluid-film bearing machines.
