Technical FAQs

1. What is the primary function of the Bently Nevada 330930-040-02-00?

It is an extension cable used between a 3300 NSv proximity probe and Proximitor sensor to maintain accurate shaft vibration and displacement measurement signals.

2. What does the model number mean?

The part number can be interpreted as:

• 330930 → 3300 NSv Extension Cable series
• 040 → 4.0 meter cable length
• 02 → Stainless steel armor, without FEP jacket
• 00 → No additional approval option

3. Does this cable include stainless steel armor?

Yes. The -02- configuration includes stainless steel armor protection.

4. Does this model have an FEP outer jacket?

No. This configuration uses stainless steel armor without an FEP jacket.

5. What systems use this extension cable?

It is designed for the Bently Nevada 3300 XL NSv proximity transducer system.

6. What equipment commonly uses this cable?

Typical applications include:

• Steam turbines
• Gas turbines
• Centrifugal compressors
• Pumps
• Motors
• Generators
• Gearboxes

7. Can it replace other 3300 extension cables?

Not always. NSv systems require matched electrical characteristics including cable length, impedance, and capacitance. Replacing with an incorrect cable type may affect calibration accuracy.

8. What should be checked before replacement?

Confirm:

• System series (NSv or standard 3300 XL)
• Cable length
• Armor requirement
• Jacket configuration
• Approval requirements
• Probe and Proximitor compatibility

9. What is the main advantage of armored construction?

It improves resistance against mechanical damage, vibration, and harsh installation conditions.

10. What components form a complete NSv measurement loop?

A typical system includes:

1. 3300 NSv proximity probe
2. 330930 extension cable
3. 330980 NSv Proximitor sensor
