The Bently Nevada 330104-00-15-10-01-CN 3300 XL 8 mm Proximity Probe is part of the industry-leading 3300 XL series proximity transducer system, designed to offer superior performance and unmatched reliability in machine condition monitoring and rotating equipment protection applications.

As a key component of the 3300 XL 8 mm system, this probe works in conjunction with a matching extension cable and Proximitor sensor to deliver precise non-contact measurements of shaft position and vibration. The probe uses advanced eddy current technology, providing an output directly proportional to the distance between the probe tip and the target metal surface — usually the rotating shaft.

The 3300 XL probes are known worldwide for their ability to operate under harsh industrial conditions, withstanding vibration, chemical exposure, moisture, and wide temperature swings. The 330104-00-15-10-01-CN model is optimized for use in critical machinery such as turbines, compressors, pumps, and motors, offering operators accurate, real-time insights into the health of rotating assets.
