The Bently Nevada 330101-00-79-10-02-05 is a 3300 XL 8 mm Proximity Probe designed for use as part of the 3300 XL 8 mm Proximity Transducer System. Within the complete system, the probe operates together with a compatible extension cable and Proximitor® Sensor to provide non-contact measurement between the probe tip and a conductive target surface.

The 3300 XL 8 mm Transducer System provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. Changes in the physical gap between the probe and target are therefore represented by corresponding changes in the system's electrical output.

The system is capable of measuring both static and dynamic values. Static measurement is used for position, while dynamic measurement is used for vibration, allowing the same transducer system to support multiple rotating machinery measurement requirements.

Primary applications include vibration and position measurements on fluid-film bearing machines. The system can also be used for Keyphasor® reference and speed measurements, providing additional measurement functions within machinery monitoring applications.
