Where It Excels in Industrial Use

• Compact Shaft Vibration and Position Monitoring:
The Bently Nevada 330905-02-10-05-02-CN is a 3300 NSv Proximity Probe designed for non-contact measurement of shaft displacement, radial vibration, and rotor position. It uses eddy-current sensing technology and is typically installed with compatible Bently Nevada Proximitor sensors and machinery protection systems.

• Small Rotating Machinery Protection Applications:
This M10 × 1 metric probe is designed for compact machinery installations where mounting space is limited. Typical applications include compressors, pumps, motors, turbines, and auxiliary rotating equipment requiring reliable shaft monitoring.

• Short Cable Installation Requirements:
The model uses a 0.5 m total length configuration, making it suitable for installations where the probe is mounted close to the Proximitor sensor or where a short probe assembly is preferred.

• Machinery Condition Monitoring and Protection:
When combined with a compatible monitoring module, the probe provides vibration and displacement signals used for detecting imbalance, misalignment, shaft instability, and other mechanical conditions in critical rotating assets. 

Key Advantages at a Glance

• High-Accuracy Eddy Current Measurement:
Provides non-contact shaft measurement without mechanical wear, enabling continuous monitoring of high-speed rotating equipment.

• 3300 NSv M10 × 1 Metric Design:
The probe uses an M10 × 1 thread and a non-armored construction, making it suitable for compact machinery applications.

• 20 mm Unthreaded Length:
The first configuration option 02 identifies a 20 mm unthreaded length design, allowing flexible mounting depth adjustment.

• 100 mm Overall Case Length:
The 10 option specifies a 100 mm overall case length configuration.

• Miniature Coaxial ClickLoc Connector:
The 02 connector option uses a miniature coaxial ClickLoc connector with standard cable for reliable signal transmission.

• CN Approval Configuration:
The -CN suffix indicates a country-specific approval option for installations requiring regional certification compliance.
