Introduction
The Bently Nevada 330130-085-02-CN is an 8.5-meter 3300 XL Standard Extension Cable designed for compatible 3300 XL proximity transducer systems. It provides the connection between the proximity probe and Proximitor Sensor while giving installation engineers the additional cable reach needed on large rotating machinery.
This configuration combines a standard 75Ω triaxial cable with connector protectors and a country-specific CN approval option. The CN suffix is associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking requirements, making this version especially relevant to projects where Chinese hazardous-location certification needs to be addressed.
With its extended 8.5-meter length and protected connector arrangement, the 330130-085-02-CN is a practical choice for turbine, compressor, pump, generator, and other critical machinery monitoring applications.

Applications
Turbine Monitoring
The 330130-085-02-CN can be integrated into proximity measurement arrangements for steam and gas turbines, where reliable shaft vibration and position signals are important for machinery protection.
Compressor Systems
Large compressors frequently require longer cable runs between field-mounted probes and monitoring equipment. The 8.5-meter configuration offers useful installation flexibility without moving the monitoring electronics closer to the machine.
Generator and Motor Monitoring
Compatible 3300 XL proximity systems can be used to monitor shaft movement and vibration on generators, motors, and other critical rotating assets. The extension cable provides the necessary signal path between the sensing element and Proximitor Sensor.
Pumps and Industrial Rotating Equipment
The cable can support proximity-based monitoring installations on pumps and other rotating equipment where continuous measurement contributes to condition monitoring and equipment protection.
Hazardous-Area Machinery
The CN approval configuration makes this model particularly relevant to installations requiring country-specific hazardous-area certification. It can be considered for applications in petrochemical, oil and gas, and other industrial environments where certification requirements are part of the project specification.
Replacement and Retrofit Projects
For existing 3300 XL installations requiring an 8.5-meter standard cable with connector protection and the CN approval configuration, the 330130-085-02-CN provides a targeted replacement solution without changing the basic measurement architecture.
Advantages
8.5-Meter Installation Reach
The 8.5-meter cable length provides considerable routing flexibility for large machinery. It allows the monitoring cabinet or Proximitor Sensor to be positioned at a practical distance from the measurement location.
Protected Cable Connections
The -02 configuration incorporates connector protectors, adding physical protection around the connection points. This can be especially useful during installation and maintenance where connectors may otherwise be exposed to accidental contact or mechanical stress.
75Ω Triaxial Construction
The 75Ω triaxial design is suited to the signal requirements of the 3300 XL proximity measurement system. Its controlled electrical characteristics support stable transmission within the complete probe-extension cable-Proximitor arrangement.
FEP Insulation
FEP insulation provides a durable insulating layer for demanding industrial instrumentation applications and contributes to the cable's suitability for machinery monitoring environments.
Country-Specific CN Approval
The CN option is the defining feature of this model. It provides a configuration intended for country-specific approval requirements, including Chinese NEPSI hazardous-area applications alongside the relevant ATEX/IECEx configuration.
Practical Balance of Protection and Flexibility
Unlike heavily armored configurations, the 330130-085-02-CN retains the standard cable format while adding protection at the connector areas. This creates a useful balance between installation flexibility and connection protection.
Designed for Established 3300 XL Systems
Because the cable belongs to the 3300 XL Standard Extension Cable family, it can be specified as part of an established 3300 XL proximity measurement architecture when the complete component configuration is correctly matched.
Technical FAQs
1. What is the Bently Nevada 330130-085-02-CN?
The 330130-085-02-CN is an 8.5-meter 3300 XL Standard Extension Cable with standard cable construction, connector protectors, and a CN country-specific approval configuration.
2. What is the cable length?
The cable length is 8.5 meters, equivalent to approximately 27.9 feet.
3. What does “085” represent?
The 085 portion identifies the 8.5-meter cable-length option in the 330130 extension cable series.
4. What does “02” mean?
The 02 option identifies the standard cable configuration with connector protectors. These protectors provide additional physical protection around the cable connection points.
5. What does the “CN” suffix indicate?
The CN suffix identifies a country-specific agency approval configuration. For this model, the CN option is associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking requirements.
6. Is the 330130-085-02-CN suitable for hazardous-area applications?
It is intended for applications where the applicable CN hazardous-area approval configuration is required. However, the complete equipment assembly and installation must satisfy the certification requirements of the actual hazardous area.
7. What cable construction does this model use?
It uses a 75Ω triaxial cable with FEP insulation and standard connector protectors.
8. What is the approximate weight?
Available product specifications list the cable at approximately 0.289 to 0.35 kg, depending on how the product dimensions and configuration are recorded. Shipping weight is substantially higher because it includes packaging.
9. What are the listed dimensions?
A listed product/package dimension for this model is approximately 20.5 × 22.5 × 3.5 cm. Because the product is a flexible cable assembly, these figures should not be interpreted as the physical length or diameter of the cable itself.
10. How does this model differ from 330130-085-02-00?
Both versions use an 8.5-meter standard cable with connector protectors. The key difference is the final approval configuration: -00 indicates that agency approval is not required, while -CN identifies the country-specific approval configuration intended for the applicable CN certification requirements.
