The Bently Nevada 330101-00-08-20-12-05 is a 3300 XL 8 mm Proximity Probe designed for use as part of the 3300 XL 8 mm Proximity Transducer System. When used together with the corresponding 3300 XL Extension Cable and 3300 XL Proximitor® Sensor, it forms a complete transducer system for non-contact shaft vibration and position measurement in rotating machinery.

The 3300 XL 8 mm Transducer System delivers the advanced performance of Bently Nevada's eddy current proximity transducer technology. The standard 3300 XL 8 mm 5-meter system fully complies with the requirements of API 670 for mechanical configuration, linear range, accuracy, and temperature stability, making it suitable for machinery protection and condition monitoring applications.

All 3300 XL 8 mm Proximity Transducer System components provide this level of performance and support complete interchangeability between proximity probes, extension cables, and Proximitor® Sensors. This interchangeable design eliminates the need to match individual components or perform bench calibration before installation, simplifying maintenance and replacement procedures.
