The Bently Nevada 330104-00-08-90-02-CN Proximity Probe Module is a high-precision non-contact eddy-current sensor designed for continuous monitoring of shaft vibration, axial position, radial displacement, and rotor dynamics in critical rotating machinery. As part of the highly regarded 3300 XL 8 mm Proximity Transducer System, this probe delivers industry-leading reliability, measurement accuracy, and long-term operational stability across a wide range of industrial applications.

This configuration incorporates an 80 mm probe case length (Option 08), an extended 9.0-meter system length (Option 90), a secure ClickLoc connector configuration (Option 02), and a CN-certified regional configuration. The combination of extended cable reach and localized certification makes this model particularly suitable for large industrial installations where monitoring systems are positioned remotely from machinery while maintaining compliance with regional project requirements.

Designed for continuous-duty operation, the 330104-00-08-90-02-CN helps operators detect developing machinery issues at an early stage, supporting predictive maintenance programs and reducing the risk of costly unplanned shutdowns.
