Product Overview

The Bently Nevada 330130-070-11-05 is a 3300 XL standard extension cable used in the Bently Nevada 3300 XL proximity transducer system.

It connects the proximity probe to the Proximitor sensor, enabling reliable transmission of vibration and displacement signals used in rotating machinery condition monitoring and protection systems.

This version provides a 7-meter cable length and is designed for industrial installations where moderate routing distance and robust signal integrity are required.

Technical Specifications

Function and Working Principle

The extension cable itself does not perform measurement. Instead, it serves as a precision analog signal transmission link within the 3300 XL system.

Signal Flow

1. Proximity probe detects shaft vibration using eddy-current sensing
2. Electrical signal is generated at the probe tip
3. Extension cable transmits the raw analog signal
4. Proximitor sensor conditions and converts the signal into calibrated output

Key Functions

• Transmits high-frequency proximity probe signals
• Maintains signal integrity over 7-meter cable runs
• Supports accurate shaft vibration and displacement measurement
• Ensures compatibility with machinery protection systems (API 670 aligned systems)
• Enables flexible installation layouts in industrial environments

System Role

The 3300 XL proximity measurement chain consists of:

• Proximity probe (sensor head)
• Extension cable (this product)
• Proximitor sensor (signal conditioning module)

Together, they provide:

• Shaft vibration monitoring
• Radial displacement measurement
• Rotor dynamic analysis
• Machinery protection and shutdown logic inputs

Industrial Applications

• Steam turbines
• Gas turbines
• Compressors
• Pumps
• Generators
• Industrial fans
• Petrochemical processing units
• Power generation plants

Installation Guidelines

• Ensure correct ClickLoc connector engagement (hand-tight connection only)
• Avoid sharp bends or mechanical stress on the cable
• Keep away from high-voltage power cables to reduce EMI interference
• Maintain proper grounding and shielding practices
• Verify full system compatibility (probe + cable + Proximitor)
• Ensure correct system length matching for calibration accuracy

Key Advantages

• Reliable signal transmission over 7 meters
• High mechanical robustness (higher cable mass variant)
• Strong EMI resistance for industrial environments
• Fully compatible with Bently Nevada 3300 XL systems
• Supports long-term condition monitoring and predictive maintenance

Technical FAQs

Q1: Does this cable measure vibration?
No. It only transmits signals between the probe and the Proximitor sensor.

Q2: Why is this model heavier than similar cables?
The 0.721 kg weight suggests a different jacket or construction variant designed for enhanced durability.

Q3: Can it be used alone?
No. It must be part of a complete 3300 XL probe–cable–Proximitor system.

Q4: Where is it used?
In turbines, compressors, pumps, generators, and other rotating machinery systems.

Conclusion

The Bently Nevada 330130-070-11-05 3300 XL Standard Extension Cable is a robust 7-meter interconnect component designed for industrial vibration monitoring systems. It ensures stable and accurate signal transmission, supporting reliable machine protection and predictive maintenance in critical rotating equipment environments.
