The Bently Nevada 330104-00-02-50-02-05 Proximity Probe Module is a high-performance non-contact sensor designed for precision shaft vibration, displacement, and position measurement in critical rotating machinery. As part of the industry-proven 3300 XL 8 mm Proximity Transducer System, this model is engineered to deliver exceptional accuracy, long-term reliability, and robust environmental resistance in demanding industrial applications.
This configuration combines a compact 20 mm probe case length with a 5.0-meter total system length, providing installation flexibility for machinery layouts that require extended cable routing. The Agency Approval Code 05 indicates compliance with internationally recognized hazardous-area certifications, including CSA, ATEX, and IECEx approvals, making it suitable for use in potentially explosive environments.
Widely used in power generation, oil and gas, petrochemical, and heavy industrial facilities, the probe provides continuous machinery condition monitoring that helps maintenance teams detect imbalance, misalignment, bearing degradation, and shaft movement abnormalities before equipment damage occurs.
