The Bently Nevada 330704-000-030-90-02-00 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 used as part of a complete eddy current proximity transducer system together with a Proximitor sensor and extension cable. The system is widely applied in turbines, compressors, pumps, and generators for continuous condition monitoring and machinery protection.
The “-030 / -90” configuration typically corresponds to a short case length with a 9.0 m cable assembly, making it suitable for installations requiring longer cable routing while maintaining a compact probe body.
According to 3300 XL 11 mm system design data, the probe family supports a typical linear measurement range of around 4 mm (160 mil) for shaft displacement monitoring in industrial applications.
