Bently Nevada 330103-00-12-10-02-CN 8 mm Proximity Probe

Overview

The Bently Nevada 330103-00-12-10-02-CN proximity probe belongs to the 3300 XL 8 mm Proximity Transducer System, engineered for continuous machinery protection and high-fidelity condition monitoring. The probe operates on eddy-current measurement principles, enabling accurate detection of shaft displacement, axial position, and dynamic vibration relative to a conductive target surface.

With a medium 12 mm probe body and a factory-integrated 10 m cable, this configuration is optimized for installations that require balanced mounting depth while maintaining signal integrity over longer routing distances. It is designed to operate reliably in demanding rotating equipment environments.

Key Design Characteristics

The 330103-00-12-10-02-CN is manufactured to tight mechanical and electrical tolerances to ensure consistent system calibration when paired with compatible 3300 XL Proximitor sensors. Its ClickLoc connector provides a mechanically secure, vibration-resistant interface, minimizing the risk of signal loss in high-speed machinery applications.

The probe supports both static and dynamic measurements, allowing it to be used for shaft position, vibration amplitude, phase reference, and speed-related monitoring functions within the same transducer platform.

FAQ

Is this probe interchangeable with non-3300 XL systems?

No. The 330103-00-12-10-02-CN is specifically calibrated for the 3300 XL 8 mm system and must be used with compatible Proximitor sensors to maintain accuracy.

What is the advantage of the 12 mm case length?

The 12 mm housing offers a balance between compact mounting and mechanical stability, making it suitable for most standard bearing housings without requiring deep probe wells.

Can this probe measure both vibration and shaft position?

Yes. It supports dynamic vibration measurements as well as static position measurements, depending on how it is configured within the monitoring system.
