Product Overview

The Bently Nevada 330130-075-02-05 is a 3300 XL standard extension cable used in the Bently Nevada 3300 XL proximity transducer system.

It provides the critical signal connection between the proximity probe and the Proximitor sensor, enabling accurate transmission of vibration and displacement measurements in rotating machinery.

This model supports a 7.5-meter cable length, making it suitable for medium-to-long routing distances in industrial installations such as turbines, compressors, and generators.

Technical Specifications

Function and Working Principle

The extension cable does not perform measurement itself. Instead, it acts as a precision analog signal transmission medium within the 3300 XL measurement chain.

Signal Flow

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

Key Functions

• Transmits high-frequency proximity probe signals
• Maintains signal integrity over 7.5-meter distance
• Supports accurate vibration and displacement monitoring
• Enables Keyphasor signal transmission for phase reference
• Compatible with machinery protection systems (API 670 aligned systems)

System Role

The 3300 XL proximity measurement chain consists of:

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

Together, they enable:

• Shaft vibration monitoring
• Radial displacement measurement
• Rotor dynamic analysis
• Machine protection and trip logic inputs

Industrial Applications

• Steam turbines
• Gas turbines
• Compressors
• Pumps
• Generators
• Industrial fans
• Petrochemical rotating equipment
• Power generation systems

Installation Guidelines

• Use proper ClickLoc connector engagement (hand-tight connection only)
• Avoid sharp bends or mechanical stress on the cable
• Keep cable away from high-voltage or high-noise electrical lines
• Ensure correct grounding and shielding practices
• Verify full system compatibility (probe + cable + Proximitor)
• Confirm correct system length configuration for calibration accuracy

Key Advantages

• Stable signal transmission over 7.5 meters
• High resistance to electromagnetic interference (EMI)
• Designed for Bently Nevada 3300 XL system compatibility
• Supports reliable condition monitoring and predictive maintenance
• Flexible installation for larger industrial equipment layouts

Technical FAQs

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

Q2: What is the difference between 075-02-05 and other variants?
The suffix indicates specific configuration options such as connector and system coding variants within the 3300 XL series.

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

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

Conclusion

The Bently Nevada 330130-075-02-05 3300 XL Standard Extension Cable is a 7.5-meter precision interconnect component designed for industrial vibration monitoring systems. It ensures reliable, low-noise signal transmission, enabling accurate machine protection and predictive maintenance in critical rotating equipment applications.
