The Bently Nevada 330102-40-12-90-02-05 is part of the 3300 XL 8 mm proximity probe series, designed for non-contact measurement of shaft vibration, displacement, and position in rotating machinery.

It is used as a component of a complete proximity transducer system together with a Proximitor sensor and extension cable. This model is commonly applied in machinery condition monitoring and protection systems where stable signal performance and long-term reliability are required.

The “90” configuration code typically indicates a special or extended system configuration variant within the ordering structure, depending on installation or application requirements.
