Where It Excels in Industrial Use

• Compact Shaft Vibration and Position Monitoring:
The Bently Nevada 330905-02-08-70-01-00 is a 3300 NSv Proximity Probe designed for non-contact measurement of shaft vibration, radial displacement, and shaft position in rotating machinery. It uses eddy-current sensing technology and is typically integrated with a 3300 XL NSv Proximitor Sensor and monitoring system.

• Small Shaft and Space-Constrained Machinery Applications:
The 3300 NSv system is intended for applications where standard proximity systems cannot be installed due to limited clearance. It is commonly used on centrifugal compressors, refrigeration compressors, process gas compressors, pumps, and other compact rotating equipment.

• Long Cable Distance Installations:
This model includes a 7.0 m total length option, making it suitable for installations where the probe location is far from the monitoring cabinet or Proximitor sensor location.

• Machinery Protection and Predictive Maintenance:
When paired with compatible Bently Nevada signal conditioning equipment, the probe provides vibration and displacement data used for detecting imbalance, misalignment, shaft instability, and other mechanical issues. 

Key Advantages at a Glance

• Non-Contact Eddy Current Measurement
Measures shaft movement without physical contact, eliminating sensor wear and allowing continuous operation on high-speed rotating equipment.

• 3300 NSv M10 × 1 Metric Design
Uses an M10 × 1 thread configuration without armor, suitable for compact machinery installations.

• Extended 7 m Cable Configuration
The 70 option specifies a 7.0 meter total length, useful for installations requiring extended distance between probe and monitoring electronics.

• ClickLoc Connector System
Uses a miniature coaxial ClickLoc connector with connector protector and standard cable configuration for secure installation.

• Chemical and Industrial Environment Compatibility
The 3300 NSv probe design provides improved chemical resistance compared with earlier 3300 RAM probe designs, supporting demanding process applications.

Technical FAQs

1. What is the main function of the Bently Nevada 330905-02-08-70-01-00?

It measures shaft displacement and vibration using a non-contact eddy-current proximity sensing system.

2. Which product family does this probe belong to?

It belongs to the Bently Nevada 3300 NSv Proximity Probe family.

3. What thread type does this probe use?

It uses an M10 × 1 metric thread.

4. What does the "-02" option indicate?

The first option identifies the unthreaded length configuration. For this model, 02 = 20 mm unthreaded length.

5. What does the "-08" option indicate?

The 08 option specifies an 80 mm overall case length.

6. What does the "-70" option indicate?

The 70 option specifies a 7.0 m total probe system length.

7. What connector type is included?

It uses a miniature coaxial ClickLoc connector with connector protector and standard cable.

8. Does the probe operate by itself?

No. It requires a compatible 3300 XL NSv Proximitor Sensor and monitoring system to provide a usable vibration/displacement output.

9. What machines commonly use this probe?

Typical applications include:

• Centrifugal compressors
• Process compressors
• Pumps
• Motors
• Turbine auxiliary systems
• Small-shaft rotating machinery

10. What should be checked before replacement?

Verify:

• Thread size (M10 × 1)
• Probe length
• Cable length
• Connector type
• Proximitor compatibility
• Required approvals
