Introduction
The Bently Nevada 330130-085-03-00 is an 8.5-meter 3300 XL Standard Extension Cable featuring an armored cable design with connector protectors. Developed for compatible 3300 XL proximity transducer systems, it provides the connection between the proximity probe and Proximitor Sensor while adding enhanced mechanical protection to both the cable and connection areas.
With its 8.5-meter reach, the cable is well suited to large rotating machines where the sensing location and monitoring equipment are positioned some distance apart. The armored construction helps protect the cable from mechanical stress, while the connector-protector configuration adds another layer of protection at the termination points.
The final -00 option indicates that no agency approval is required for this particular ordering configuration. For standard industrial machinery monitoring projects where special hazardous-area certification is not required, the 330130-085-03-00 offers a robust and practical extension-cable solution.

Applications
Turbine and Generator Monitoring
The 330130-085-03-00 can be integrated into 3300 XL proximity measurement systems used on steam turbines, gas turbines, generators, and other critical rotating equipment. Its extended length allows greater flexibility when routing the measurement signal between the machine and monitoring electronics.
Compressor Monitoring
Large compressors can have considerable distances between probe mounting points and instrumentation equipment. The 8.5-meter cable provides useful installation reach while maintaining the established 3300 XL system configuration.
Pump and Motor Applications
Compatible proximity measurement systems can be used to monitor shaft vibration and position on pumps, motors, and other rotating equipment. The armored cable construction is especially useful where the cable route is exposed to mechanical interference.
Fluid-Film Bearing Machinery
Proximity probes are commonly used around fluid-film bearings to measure shaft movement and dynamic behavior. The extension cable forms part of the signal path between the probe and Proximitor Sensor in these installations.
Industrial Machinery Protection
The combination of armor and connector protection makes this configuration well suited to industrial environments where cables may be exposed to vibration, abrasion, maintenance activity, or accidental mechanical contact.
Replacement and Retrofit Projects
For an installed 3300 XL system that specifically calls for an 8.5-meter armored extension cable with connector protectors and no special agency approval, the 330130-085-03-00 provides a direct configuration match.
Advantages
Extended 8.5-Meter Reach
The 8.5-meter length provides substantial routing flexibility around large machinery. It can help engineers position monitoring equipment in a convenient location without unnecessarily relocating the Proximitor Sensor.
Armored Cable Protection
The -03 configuration uses armored cable construction, providing additional mechanical protection compared with standard unarmored cable. This is valuable in industrial areas where instrumentation cables may encounter abrasion, impact, pulling forces, or other physical stresses.
Protected Connection Points
Cable damage is not limited to the cable body itself. The connector areas can also be vulnerable during installation and maintenance. The integrated connector protectors provide additional physical protection at these critical points.
75Ω Triaxial Signal Path
The 75Ω triaxial cable design is intended for the electrical requirements of the 3300 XL proximity measurement system. Its defined capacitance characteristics support predictable signal transmission within a properly configured measurement chain.
FEP Insulation
FEP insulation provides durable electrical isolation for industrial instrumentation applications and is well suited to the demanding environments associated with rotating machinery monitoring.
Stronger Overall Installation Protection
By combining armored cable construction with connector protectors, the 330130-085-03-00 provides a more rugged installation solution than the standard cable and connector-protector configuration alone.
Straightforward Standard Configuration
The final -00 approval option indicates that no agency approval is required. This keeps the configuration straightforward for conventional industrial applications where additional hazardous-area certification is not part of the project specification.
Designed Around the 3300 XL System
The cable is specifically part of the 3300 XL Standard Extension Cable family rather than a generic instrumentation cable. This makes it a natural choice when maintaining a compatible 3300 XL proximity measurement system.
Technical FAQs
1. What is the Bently Nevada 330130-085-03-00?
The 330130-085-03-00 is a Bently Nevada 3300 XL Standard Extension Cable with an 8.5-meter length, armored construction, and connector protectors.
2. How long is the 330130-085-03-00?
The cable length is 8.5 meters, or approximately 27.9 feet.
3. What does “085” mean?
The 085 designation identifies the 8.5-meter cable-length option within the 330130 series.
4. What does “03” mean?
The 03 designation identifies an armored cable with connector protectors. It therefore provides both cable-body protection and additional protection around the connection areas.
5. What does the final “00” indicate?
The 00 agency approval option indicates that no special agency approval is required for this configuration.
6. What type of cable is used?
The 330130-085-03-00 uses a 75Ω triaxial cable with FEP insulation in an armored configuration.
7. What is the approximate weight?
The commonly listed cable weight is approximately 0.034 kg per meter, resulting in an estimated cable weight of approximately 0.289 kg for an 8.5-meter assembly. Actual packaged shipping weight can be considerably higher.
8. What is the difference between 330130-085-02-00 and 330130-085-03-00?
Both models are 8.5-meter cables with connector protectors. The key difference is cable construction: -02 uses a standard cable with connector protectors, while -03 uses an armored cable with connector protectors.
9. Is this cable intended for the 3300 XL 8 mm proximity system?
Yes. The 330130 series is used as the extension-cable component of compatible 3300 XL proximity transducer systems. The extension cable and probe lengths should be selected so their combined length matches the required Proximitor Sensor system configuration.
