The Bently Nevada 330704-000-050-90-02-00 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 Bently Nevada eddy current proximity transducer system and is used together with a Proximitor sensor and extension cable. The system provides continuous monitoring of rotor dynamics in turbines, compressors, pumps, and generators for condition monitoring and machinery protection.
The “-050 / -90 / -02-00” configuration typically represents a 50 mm case length, a 9.0 m system cable length, ClickLoc connector type, and standard approval option within the 3300 XL ordering structure.
The 11 mm probe family is designed for a typical linear measurement range of around 4 mm (160 mil), enabling accurate vibration and position monitoring in fluid-film bearing machines.
