Introduction — High-Stability Proximity Measurement for Critical Rotating Machinery
The Bently Nevada 330103-00-05-05-12-05 3300 XL 8 mm Proximity Probe is a precision eddy current sensor designed for continuous monitoring of shaft vibration, displacement, and position in rotating machinery. As part of the widely adopted 3300 XL proximity transducer system, it delivers stable output performance, strong environmental resistance, and long-term measurement reliability for industrial condition monitoring applications.
The “12” segment in the configuration code typically indicates a FluidLoc® cable option with ClickLoc® connector system, improving sealing performance and installation robustness in demanding environments. The 3300 XL platform is widely used in turbine, compressor, and critical rotating equipment monitoring systems compliant with API 670-based design practices.
