Introduction
The Bently Nevada 330130-085-13-CN is an 8.5-meter 3300 XL Standard Extension Cable developed for compatible 3300 XL proximity transducer systems. It combines an armored FluidLoc cable with connector protectors, creating a highly protected cable configuration for demanding rotating machinery installations.
The part number provides a useful guide to its configuration. 085 identifies the 8.5-meter cable length, 13 specifies the armored FluidLoc cable with connector protectors, and CN identifies the country-specific agency approval option. Available product specifications associate the CN configuration with ATEX/IECEx and Chinese NEPSI hazardous-area marking.
Compared with a conventional extension cable, this configuration offers a stronger combination of mechanical protection and fluid-migration control. It is therefore well suited to turbines, compressors, generators, pumps, and other critical machinery where the cable itself forms an important part of the proximity measurement chain.

Applications
Turbine Machinery Monitoring
The 330130-085-13-CN is designed for integration into compatible 3300 XL proximity measurement systems used on steam and gas turbines. Its armored construction is advantageous where cable routing around turbine equipment presents increased mechanical exposure.
Compressor Protection
Large compressors often place proximity probes near bearings or shafts while signal-conditioning components are installed farther away. The 8.5-meter cable provides useful routing flexibility while the armored FluidLoc design adds protection against environmental and physical stresses.
Oil-Lubricated Equipment
FluidLoc is particularly valuable around machinery where lubricating oil or other liquids may come into contact with the cable. The configuration is designed to help limit fluid migration through the cable assembly.
Generator and Motor Monitoring
Compatible 3300 XL systems can monitor shaft vibration and position on generators and motors. The armored extension cable offers additional protection where cable routes are exposed to surrounding equipment or maintenance activity.
Pumps and Auxiliary Rotating Equipment
Industrial pumps and auxiliary machinery can require proximity-based condition monitoring in areas where cable protection is important. The 330130-085-13-CN provides a durable extension option for these installations.
Hazardous-Area Industrial Systems
The CN configuration is intended for applications requiring the applicable country-specific approval arrangement. Available specifications associate the CN option with ATEX/IECEx and Chinese NEPSI hazardous-area marking.
Retrofit and Replacement Projects
For an existing 3300 XL system requiring an 8.5-meter armored FluidLoc extension cable with connector protectors and the CN approval configuration, this model offers a clearly defined replacement choice without changing the basic proximity measurement architecture.
Advantages
Armored FluidLoc Construction
The main strength of the 13 configuration is the combination of armor and FluidLoc. Armor helps protect against mechanical damage, while FluidLoc addresses fluid migration. Together they provide broader environmental protection than a conventional standard cable.
Connector Protection
The integrated connector-protector configuration adds protection around the termination area. This can be especially useful in machinery installations where connectors are exposed to vibration, handling, maintenance work, or surrounding equipment.
8.5-Meter Reach
The 8.5-meter cable length provides significant routing flexibility. It can help position the Proximitor Sensor and related instrumentation in a more accessible location while maintaining the required connection to the proximity probe.
Stable Electrical Characteristics
The 75Ω triaxial construction and approximately 69.9 pF/m typical capacitance are designed around the 3300 XL proximity measurement system. Using the correctly specified cable helps maintain the intended electrical characteristics of the measurement chain.
FEP Insulation
FEP insulation provides reliable electrical isolation and is well suited to industrial instrumentation applications requiring a durable cable construction.
Country-Specific Approval Option
The CN suffix differentiates this model from the 00 and 05 variants. It is intended for country-specific approval requirements and is associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking. Correct suffix selection is therefore particularly important for regulated installations.
Enhanced Mechanical Durability
The armored construction gives this model an advantage over unarmored configurations where the cable route may be exposed to abrasion, physical contact, or other mechanical hazards.
Purpose-Built 3300 XL Integration
The 330130 series is designed as part of the 3300 XL proximity transducer system. Using the appropriate extension cable helps maintain a correctly matched probe, extension-cable, and Proximitor Sensor arrangement.
Technical FAQs
1. What is the Bently Nevada 330130-085-13-CN?
It is a 3300 XL Standard Extension Cable featuring an 8.5-meter length, armored FluidLoc construction, connector protectors, and the CN country-specific approval configuration.
2. How long is the cable?
The nominal cable length is 8.5 meters (27.9 feet). The 085 option identifies this cable length.
3. What does “13” mean?
The 13 configuration specifies an armored FluidLoc cable with connector protectors.
4. What does “CN” indicate?
The CN suffix identifies the country-specific agency approval option. Product specifications associate this configuration with ATEX/IECEx and Chinese NEPSI hazardous-area marking.
5. What is FluidLoc used for?
FluidLoc is intended to help restrict the migration of oil and other liquids through the cable assembly. It is especially useful around oil-lubricated machinery and other installations where fluid exposure is a concern.
6. Is the cable armored?
Yes. The 13 configuration is specifically an armored FluidLoc cable. This provides additional mechanical protection compared with unarmored FluidLoc configurations.
7. Does the 330130-085-13-CN include connector protectors?
Yes. The 13 configuration includes connector protectors as part of the cable configuration.
8. What is the approximate cable weight?
The listed cable weight is approximately 0.289 kg. Shipping weight is listed separately at approximately 2 kg by some suppliers.
9. What dimensions are relevant for installation?
Because this is a flexible armored cable assembly, the most useful installation parameters are the 8.5-meter length, cable outside diameter, connector-protector dimensions, bend requirements, and available routing space rather than a rectangular product dimension.
10. How does the 330130-085-13-CN differ from 330130-085-13-05?
The two models share the same 8.5-meter armored FluidLoc and connector-protector configuration, but their approval suffixes are different. The -05 version is the multiple-approval configuration associated with CSA, ATEX, and IECEx, while -CN uses the country-specific approval configuration associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking. The appropriate version should be selected according to the certification requirements of the installation.
