Where It Excels in Industrial Use

• Compact Shaft Vibration and Position Monitoring:
The Bently Nevada 330905-03-10-50-02-00 is a 3300 NSv Proximity Probe designed for non-contact measurement of shaft displacement, radial vibration, and rotor position in rotating machinery. It uses eddy-current sensing technology and is intended for use with compatible 3300 XL NSv Proximitor Sensors and monitoring systems.

• Small-Clearance Machinery Applications:
The 3300 XL NSv series is designed for applications where standard proximity probes cannot fit due to limited installation space. Typical uses include centrifugal compressors, refrigeration compressors, process gas compressors, pumps, motors, and other small rotating machines.

• Extended Cable Installation:
This model uses a 5.0 m total length configuration, allowing the probe to be installed at the machine while the Proximitor sensor is located remotely in a junction box, cabinet, or control panel.

• Machinery Protection and Predictive Maintenance:
When combined with a compatible Proximitor sensor and monitor module, the probe provides vibration and position signals used for machine protection, alarm processing, and condition monitoring. 

Key Advantages at a Glance

• Non-Contact Eddy Current Technology
Measures shaft movement without physical contact, enabling continuous monitoring of high-speed rotating equipment.

• M10 × 1 Metric Probe Construction
The 330905 series identifies an M10 × 1 threaded, non-armored 3300 NSv probe design.

• 30 mm Unthreaded Length
The first code 03 indicates a 30 mm unthreaded length configuration. The unthreaded length is selected according to mounting requirements and must remain shorter than the overall case length.

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

• 5.0 m Total Length
The 50 option specifies a 5.0 m (16.4 ft) total probe system length.

• Miniature Coaxial ClickLoc Connector
The 02 option specifies a miniature coaxial ClickLoc connector with standard cable.
