Introduction
The Bently Nevada 330130-070-00-00 is a 7.0-meter 3300 XL Standard Extension Cable developed for compatible 3300 XL proximity transducer systems. With its standard, unarmored construction, the cable provides a clean and practical connection path for installations where additional cable length is needed but heavy mechanical armor is not required.
The model configuration is straightforward: 070 represents the 7.0-meter cable length, the first 00 identifies the standard cable option, and the final 00 indicates that no agency approval option is specified. This makes the 330130-070-00-00 a useful choice for conventional 3300 XL installations with protected cable routing.
At 7 meters, this model offers more routing freedom than shorter 3300 XL extension cables while maintaining a slim cable profile. It is well suited to machinery-monitoring systems where reliable proximity measurements depend on correctly matching the probe, extension cable, and Proximitor® sensor as a complete measurement chain.

Applications
Proximity-Based Machinery Monitoring
The 330130-070-00-00 forms part of compatible 3300 XL proximity transducer arrangements used to monitor rotating machinery. It can provide the required extension between the probe installation point and the associated Proximitor® sensor.
Turbine and Compressor Equipment
Large turbines and compressors frequently place sensing points some distance from monitoring electronics. The 7-meter configuration provides useful routing reach while retaining the compact dimensions of a standard cable.
Pumps, Motors, and Generators
The cable can be incorporated into suitable proximity-monitoring arrangements for pumps, motors, generators, and other rotating equipment where shaft vibration, position, or displacement measurements are required.
Protected Industrial Installations
The standard unarmored design is particularly appropriate when the cable can be installed inside protected cable routes. It avoids the additional bulk of armored versions where physical protection beyond the standard jacket is unnecessary.
Maintenance Replacement
For plants already using a 7-meter 3300 XL extension cable, the 330130-070-00-00 provides a clearly identified replacement configuration. Matching the exact part number helps preserve the original cable length and construction.
Machinery Retrofit Projects
During retrofit work, the 7-meter length can provide useful flexibility when existing cable routes cannot be easily relocated. It can help bridge the distance between sensing locations and externally mounted monitoring components without requiring changes to the machinery layout.
Advantages
A Practical 7-Meter Configuration
The 7.0-meter length provides a useful amount of installation reach for medium-distance machinery layouts. It gives engineers more freedom than shorter 4.5- or 6-meter options while remaining manageable during installation.
Slim, Unarmored Construction
The standard cable configuration keeps the assembly relatively compact. With an approximate maximum diameter of 3.7 mm, it is easier to route through confined areas than larger armored alternatives.
Defined Electrical Characteristics
The 3300 XL extension cable is not simply a generic wire extension. Its cable characteristics form part of the proximity measurement system, so using the specified 3300 XL cable helps maintain the intended electrical relationship between the probe, extension cable, and Proximitor® sensor.
FEP Jacket Construction
The standard cable uses an FEP jacket, providing a compact protective outer layer suitable for many industrial instrumentation environments.
Broad Temperature Capability
Published technical information identifies an operating temperature range of approximately -51°C to +177°C, making the cable suitable for a wide range of machinery-monitoring environments when the complete installation is properly engineered.
Easy-to-Manage Installation
The combination of a 7-meter reach and slim cable construction provides a useful balance between routing flexibility and cable management. For protected machinery areas, this can be more convenient than selecting an armored configuration that the application does not require.
Straightforward Spare-Part Identification
The complete 330130-070-00-00 part number clearly defines the length and standard configuration. This makes it a practical inventory item for maintenance teams supporting established 3300 XL systems.
Technical FAQs
1. What is the Bently Nevada 330130-070-00-00?
The 330130-070-00-00 is a 3300 XL Standard Extension Cable with a nominal length of 7.0 meters and a standard, unarmored cable configuration.
2. How long is the 330130-070-00-00?
The cable is 7.0 meters (22.9 feet) long. The 070 portion of the part number identifies this length option.
3. Is this an armored extension cable?
No. The first 00 configuration identifies the standard cable option. Armored 3300 XL extension cables use different configuration codes.
4. What does the final “00” mean?
The final 00 represents the agency-approval option and indicates that additional agency approval is not required for this configuration.
5. What is the approximate cable diameter?
The standard cable has a maximum outside diameter of approximately 3.7 mm (0.15 in). This compact profile can simplify installation in confined machinery areas.
6. What type of cable is used?
The 330130-070-00-00 is identified as a 75-ohm triaxial extension cable with an FEP jacket. Its electrical characteristics are intended for use within the 3300 XL proximity measurement architecture.
7. What is the approximate weight?
The cable assembly itself is approximately 238–240 g based on available product information. Supplier-listed shipping weight can be approximately 2 kg because it may include packaging and other shipping materials.
8. Does the cable require an external power supply?
No. The extension cable is a passive component and does not require a separate power supply.
9. Can it be used with a 3300 XL 8 mm proximity system?
Yes, it is part of the 3300 XL extension-cable family used with compatible 3300 XL proximity transducer arrangements. The complete probe, extension cable, and Proximitor® sensor combination must be correctly matched.
10. What should be verified before purchasing?
Check the complete 330130-070-00-00 part number, required 7-meter length, standard cable construction, connector configuration, approval requirements, compatible probe, Proximitor® sensor, and total electrical system length. If the cable route is exposed to significant mechanical stress, an armored alternative should be evaluated instead.
