Introduction
The Bently Nevada 330130-070-01-00 is a 7.0-meter 3300 XL Standard Extension Cable with armored construction, designed for compatible 3300 XL proximity transducer systems. It provides the extended electrical connection required between a proximity probe and its associated Proximitor® sensor while adding a protective armor layer for installations where the cable route may be exposed to greater mechanical stress.
The part number clearly defines the configuration: 070 specifies the 7.0-meter length, 01 identifies the armored cable option, and the final 00 indicates that no additional agency approval option is required. This makes the model different from the standard 330130-070-00-00 cable, even though both provide the same nominal cable length.
For industrial maintenance and machinery-monitoring projects, the 330130-070-01-00 offers a strong combination of long installation reach and improved physical protection. It is particularly useful when proximity-monitoring cables must pass near machinery structures, equipment frames, or other areas where an unarmored cable could be more vulnerable to abrasion or accidental mechanical contact.

Applications
Turbine Machinery Monitoring
The 330130-070-01-00 is well suited to compatible proximity-monitoring systems installed around turbines. Its armored construction provides additional protection where the cable route passes through mechanically demanding equipment areas.
Compressor Applications
Compressors can involve crowded equipment layouts and complex instrumentation routes. A 7-meter extension provides useful reach, while the armor helps protect the cable from accidental contact with surrounding machinery or structures.
Pumps and Motors
For pumps, motors, generators, and other rotating assets, the cable can form part of a 3300 XL proximity measurement chain used for shaft vibration, displacement, or position monitoring.
Industrial Machinery Installations
The armored construction is especially valuable where cables are routed close to machinery frames, support structures, cable trays, or other areas where abrasion and physical impact are possible.
Maintenance Replacement
The 330130-070-01-00 is an appropriate reference when an existing system specifically calls for a 7-meter armored 3300 XL extension cable without an additional agency-approval option. Matching the complete part number helps avoid replacing an armored cable with a standard unarmored version by mistake.
Retrofit Projects
In retrofit applications, existing cable routes may be difficult to modify. The combination of 7-meter reach and mechanical protection can make this configuration a practical solution without requiring extensive changes to the machinery or instrumentation layout.
Advantages
Armored Protection
The defining feature of the 330130-070-01-00 is its armored construction. Compared with a standard unarmored 00 configuration, the armor provides an additional physical barrier against abrasion, accidental contact, and mechanical handling during installation.
Seven-Meter Reach
The 7.0-meter cable length provides substantial routing flexibility for larger machinery installations. It can help bridge the distance between a probe location and Proximitor® sensor without resorting to unnecessarily long cable configurations.
Compact Armored Design
Although protected by armor, the cable remains relatively compact. The armored section has a maximum diameter of approximately 7.67 mm, allowing it to fit into many industrial cable routes while providing substantially more mechanical protection than the underlying 3.7 mm cable alone.
Defined 75-Ohm Construction
The extension cable uses the specified 75-ohm triaxial cable construction required by the compatible 3300 XL proximity measurement architecture. This is important because the extension cable is part of the measurement circuit rather than simply a generic signal cable.
Suitable for Challenging Cable Routes
Where a standard cable can be installed in a protected location, the 00 configuration may be sufficient. Where the route is more exposed to mechanical stress, the 01 armored option provides a more robust installation approach.
Reliable Maintenance Reference
The complete 330130-070-01-00 designation clearly identifies the cable length, armor option, and approval configuration. This is valuable for maintenance departments that need to keep exact replacement components available.
Professional Installation Flexibility
The 7-meter length gives technicians additional room to route the cable cleanly around equipment without excessive tension. Correct cable routing can also make future inspection and replacement work easier.
Technical FAQs
1. What is the Bently Nevada 330130-070-01-00?
It is a 3300 XL Standard Extension Cable with a nominal 7.0-meter length, armored cable construction, and no additional agency-approval option.
2. How long is the 330130-070-01-00?
The nominal cable length is 7.0 meters (22.9 feet). The “070” portion of the part number identifies the length option.
3. Is the 330130-070-01-00 armored?
Yes. The 01 cable option identifies the armored cable configuration.
4. What does the final “00” mean?
The final 00 identifies the agency-approval option as not required for this configuration.
5. What is the diameter of the armored section?
The maximum outside diameter of the armored portion is approximately 7.67 mm (0.302 in). The underlying cable has a maximum diameter of approximately 3.7 mm (0.15 in).
6. What is the armor ferrule diameter?
The armor ferrule can have a maximum diameter of approximately 10.2 mm (0.40 in). This dimension should be included when checking cable-entry and routing clearance.
7. How much does the cable weigh?
The cable mass is approximately 34 g/m, giving an estimated physical cable mass of around 0.24 kg for 7 meters. Shipping weight can be considerably higher because it includes packaging and other materials.
8. Is the armored cable electrically different from the standard cable?
The armor primarily adds mechanical protection. The underlying extension cable remains part of the specified 3300 XL measurement architecture, with its defined electrical characteristics. The complete cable configuration should therefore be selected according to the system requirements rather than treating the armor as a generic add-on.
9. Can the 330130-070-01-00 replace the 330130-070-00-00?
The two models share the same nominal 7-meter length, but they have different cable constructions. The 330130-070-01-00 is armored, while the 330130-070-00-00 is standard unarmored. The armored version should therefore be selected when its physical protection is required or when the existing system specifies the 01 configuration.
10. What should be checked before ordering this cable?
Confirm the complete 330130-070-01-00 part number, 7-meter length, armored construction, approval requirement, compatible proximity probe, Proximitor® sensor, total electrical system length, and available routing space. The armor diameter and ferrule dimensions should also be considered when cable clearance is limited.
