Introduction
The Bently Nevada 330130-085-12-CN is an 8.5-meter 3300 XL Standard Extension Cable configured with FluidLoc protection and a connector protector. Designed for compatible 3300 XL proximity transducer systems, this cable provides the extended connection between a proximity probe and Proximitor Sensor while adding protection against fluid migration and mechanical exposure around the connector area.
The 085 configuration identifies the 8.5-meter cable length, while 12 specifies the FluidLoc cable with connector protector. The CN suffix identifies the corresponding country-specific approval configuration, making this version particularly relevant to installations where the applicable ATEX/IECEx and Chinese NEPSI hazardous-area requirements need to be addressed.
With its extended reach, 75Ω triaxial construction, FEP insulation, and combined FluidLoc and connector protection, the 330130-085-12-CN is a practical solution for critical rotating machinery applications where cable reliability is an important part of the overall vibration and shaft-position monitoring system.

Applications
Turbine Vibration Monitoring
The 330130-085-12-CN can be integrated into compatible 3300 XL proximity measurement arrangements for steam and gas turbines. Its 8.5-meter length gives installers additional flexibility when routing signals from turbine-mounted probes to Proximitor Sensors and associated monitoring equipment.
Compressor Protection Systems
Large compressors often have limited space around the measurement point while their signal-conditioning equipment is positioned farther away. The extended cable length makes it easier to establish a clean and practical probe-to-Proximitor connection.
Oil-Exposed Machinery
The FluidLoc design is particularly useful where cables are routed through areas exposed to lubricating oil or other fluids. It is intended to help restrict fluid migration through the cable assembly, supporting better long-term installation integrity.
Generator and Motor Monitoring
Compatible 3300 XL systems can be used for shaft vibration and position measurement on generators, motors, and other rotating assets. The 330130-085-12-CN provides the required extension while adding protection at the cable connection.
Pumps and Auxiliary Rotating Equipment
Industrial pumps and auxiliary machinery can also benefit from proximity monitoring. The FluidLoc and connector-protection features make this configuration useful where environmental exposure is more demanding than in a protected instrumentation cabinet.
Hazardous-Area Applications
The CN approval configuration is intended for projects requiring the applicable country-specific hazardous-area marking. Where ATEX, IECEx, or Chinese NEPSI requirements apply, the complete certified system and installation must be checked against the actual hazardous-area classification.
Maintenance and Retrofit Projects
For existing 3300 XL installations requiring an 8.5-meter FluidLoc cable with connector protection and the CN approval configuration, this model provides a clearly defined replacement option.
Advantages
Dual Protection in One Configuration
The -12 option combines FluidLoc protection with a connector protector, addressing both fluid migration and connector-area exposure. This makes it more protective than a basic extension-cable configuration.
8.5-Meter Installation Reach
An 8.5-meter cable offers useful flexibility around large turbines, compressors, generators, and pumps. It allows monitoring hardware to be positioned in a practical location without unnecessarily relocating other system components.
FluidLoc Cable Design
FluidLoc helps address one of the most common environmental concerns in machinery instrumentation: the migration of oil or other fluids along the cable path. This feature is particularly valuable around oil-lubricated machinery.
Protected Connector Area
The connector protector adds a dedicated layer of protection around the termination area. This can be beneficial during installation, servicing, and routine maintenance where cable connections may otherwise be vulnerable.
75Ω Triaxial Construction
The 75Ω triaxial construction is designed for the electrical requirements of the 3300 XL proximity measurement system. Its controlled characteristics support consistent signal transmission when used with compatible system components.
FEP Insulation
FEP insulation provides reliable electrical separation and is appropriate for demanding industrial instrumentation environments.
CN Configuration
The CN suffix distinguishes this model from the 05 and other approval variants. It provides the configuration associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking, making correct suffix selection especially important for regulated installations.
Purpose-Built for Proximity Monitoring
The 330130 series is designed as part of the 3300 XL proximity transducer architecture. Using the appropriate extension cable helps maintain a correctly configured measurement chain from the probe to the Proximitor Sensor.
Technical FAQs
1. What is the Bently Nevada 330130-085-12-CN?
It is a 3300 XL Standard Extension Cable with an 8.5-meter length, FluidLoc cable construction, connector protector, and CN approval configuration.
2. How long is the 330130-085-12-CN?
The cable length is 8.5 meters, or approximately 27.9 feet.
3. What does “085” mean?
The 085 code identifies the 8.5-meter cable-length option.
4. What does “12” represent?
The 12 configuration specifies a FluidLoc cable with connector protector. It provides additional environmental and mechanical protection compared with a basic FluidLoc cable.
5. What does “CN” mean?
The CN suffix identifies the country-specific approval configuration associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking. The exact certification requirements should be confirmed against the intended installation.
6. What is the purpose of FluidLoc?
FluidLoc is designed to help prevent oil and other liquids from migrating through the cable assembly. This is particularly useful when a cable passes from an oil-containing machine area toward external instrumentation.
7. What type of cable construction does it use?
The cable uses a 75Ω triaxial construction with FEP insulation and a typical capacitance of approximately 69.9 pF/m.
8. What is the approximate weight?
The cable assembly is commonly specified at approximately 0.29 kg, while the shipping weight is approximately 1.5 kg. Shipping weight includes packaging and should not be confused with the bare cable weight.
9. What dimensions should be considered when installing it?
The 330130-085-12-CN is a flexible cable assembly, so its 8.5-meter length, cable diameter, connector dimensions, and permissible routing/bend requirements are more useful for installation planning than a fixed rectangular product dimension.
10. How does the 330130-085-12-CN differ from 330130-085-10-CN?
Both are 8.5-meter FluidLoc configurations with the CN approval option. The key difference is that -12 adds a connector protector, whereas -10 is the FluidLoc cable configuration without the additional connector-protector option. If connector-area protection is required, the -12 version is the more appropriate configuration.
