Product Overview

The Bently Nevada 330130-070-02-05 is a 3300 XL standard extension cable used in the Bently Nevada 3300 XL proximity transducer system.

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

With a 7-meter cable length, it is suitable for medium-to-long distance installations in turbines, compressors, generators, and other industrial equipment.

Technical Specifications

Function and Working Principle

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

Signal Flow

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

Key Functions

• Transmits high-frequency probe signals with minimal distortion
• Maintains measurement accuracy over 7-meter distance
• Ensures stable vibration and displacement monitoring
• Supports machinery protection systems (API 670 compliant)
• Enables flexible installation layouts in industrial plants

System Role

The 3300 XL proximity measurement system consists of:

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

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 rotating equipment
• Power generation systems

Installation Guidelines

• Use proper ClickLoc connector engagement (hand-tight connection)
• Avoid tight bends or mechanical stress on cable
• Keep away from high-voltage or high-noise power lines
• Ensure proper grounding and shielding
• Maintain correct system matching (probe + cable + Proximitor)
• Verify total system length for calibration accuracy

Key Advantages

• Reliable signal transmission over 7 meters
• High immunity to industrial electromagnetic interference
• Designed for Bently Nevada 3300 XL system compatibility
• Supports long-term condition monitoring systems
• Ensures stable and accurate vibration measurement data

Technical FAQs

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

Q2: Can it be used alone?
No. It must be used with a probe and Proximitor sensor.

Q3: Why is system matching important?
Because the 3300 XL system is calibrated as a complete matched measurement chain.

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

Conclusion

The Bently Nevada 330130-070-02-05 3300 XL Standard Extension Cable is a key interconnect component in industrial vibration monitoring systems. It ensures stable and accurate signal transmission over 7 meters, enabling reliable machine protection and predictive maintenance in critical rotating equipment.
