Industrial-Grade Precision Monitoring for Critical Rotating Machinery
The Bently Nevada 330101-30-63-15-02-CN 3300 XL 8 mm Proximity Probe is a high-reliability eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, displacement, and position in rotating machinery systems. As part of the widely used 3300 XL proximity transducer family, it provides stable signal output, strong noise immunity, and consistent long-term performance in demanding industrial environments.
This configuration (30-63-15-02-CN) is typically associated with a 3.0-inch unthreaded length, 6.3-inch case length, 1.5-meter system cable, ClickLoc connector, and CN certification option (CSA/ATEX/IECEx compliant configuration), making it suitable for heavy-duty turbomachinery applications requiring extended probe reach and certified installation standards.
Built with stainless steel housing and a PPS sensing tip, it is engineered for durability under vibration stress, thermal cycling, and corrosive industrial conditions while maintaining measurement accuracy.
