The Bently Nevada 330704-000-050-10-01-05 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 used as part of the Bently Nevada eddy current proximity transducer system together with a Proximitor sensor and extension cable. This system is widely applied in turbines, compressors, pumps, and generators for continuous condition monitoring and machinery protection.
The 050 configuration typically indicates a 50 mm case length, while the 10-01-05 suffix represents a standard 1.0 m system length with ClickLoc connector and multiple approval configuration for broader industrial compliance.
The 3300 XL 11 mm system provides a typical linear output sensitivity of 3.94 V/mm (100 mV/mil) and is designed for applications requiring a longer linear range than 8 mm probes.
