Introduction
The Bently Nevada 330130-085-13-RU is an 8.5-meter 3300 XL Standard Extension Cable designed for use with compatible 3300 XL proximity transducer systems. Its configuration combines an armored FluidLoc cable with connector protectors, giving the cable a higher level of mechanical and environmental protection than a conventional standard extension cable.
The ordering code provides a clear description of the configuration. 085 identifies the 8.5-meter cable length, while 13 specifies the armored FluidLoc cable with connector protectors. The RU suffix identifies the country-specific approval configuration, making this model distinct from otherwise similar 330130 cables carrying 00, 05, or CN approval suffixes.
For critical rotating machinery, the extension cable is not simply a passive length of wire. It forms part of the probe-to-Proximitor signal path and must be correctly matched to the installed 3300 XL system. The 330130-085-13-RU combines long installation reach with armored protection and FluidLoc technology, making it a compelling choice for demanding industrial monitoring environments.

Applications
Steam and Gas Turbine Monitoring
The 330130-085-13-RU is suitable for compatible 3300 XL proximity monitoring arrangements used around steam and gas turbines. Its 8.5-meter reach allows greater flexibility between machine-mounted probes and remotely positioned Proximitor Sensors.
Compressor Machinery
Large compressors can place proximity probes in locations where the associated monitoring electronics are some distance away. The extended cable length simplifies routing, while the armored FluidLoc construction adds protection in demanding equipment areas.
Oil-Lubricated Machinery
FluidLoc is particularly useful around machinery where lubricating oil or other fluids may be present. The cable construction is intended to help limit fluid migration through the cable assembly.
Generator and Motor Monitoring
The cable can form part of a compatible 3300 XL proximity measurement chain used for shaft vibration and position monitoring. The armored configuration is beneficial where the cable route may be exposed to surrounding machinery or maintenance activity.
Pumps and Auxiliary Rotating Equipment
Industrial pumps and auxiliary rotating equipment often operate in environments where vibration, oil, and physical contact can challenge instrumentation cabling. The 330130-085-13-RU provides a more protected extension solution for such installations.
Heavy-Duty Industrial Installations
The combination of armor, FluidLoc, and connector protection makes this configuration particularly suitable where a basic unarmored cable would leave the installation unnecessarily exposed to mechanical or environmental risks.
Hazardous-Area Projects
The RU suffix indicates a country-specific approval configuration. When the cable is intended for a classified location, the exact certification and marking requirements should be checked against the project documentation and the complete installed measurement system rather than assuming that every 330130 approval suffix is interchangeable.
Replacement and Retrofit Work
For an existing 3300 XL system that specifically calls for an 8.5-meter armored FluidLoc cable with connector protectors and the RU approval configuration, selecting the complete 330130-085-13-RU part number helps preserve the intended installation specification.
Advantages
Armored FluidLoc Protection
The 13 configuration combines mechanical armor with FluidLoc protection. These two features address different installation risks: armor helps protect against physical damage, while FluidLoc helps control fluid migration through the cable.
Integrated Connector Protection
Connector protectors are included in the 13 configuration, providing additional protection at the cable termination. This is especially useful in machinery areas where connections may be exposed to vibration, handling, or accidental contact.
8.5-Meter Installation Reach
The 8.5-meter length provides substantial routing flexibility around large rotating machines. It allows instrumentation engineers to position the Proximitor Sensor away from the immediate machinery area when the installation layout requires it.
Consistent Electrical Characteristics
The 330130 extension cable is designed around the 3300 XL proximity transducer architecture. Its 75Ω triaxial construction and defined capacitance help maintain the expected electrical characteristics of the measurement path.
FEP-Insulated Construction
FEP insulation provides dependable electrical isolation and is well suited to industrial instrumentation applications where environmental durability is important.
Enhanced Mechanical Durability
The armored construction gives the cable additional protection compared with standard unarmored versions. This is valuable when cable routing passes close to machinery structures or other areas where abrasion or accidental impact is possible.
Fluid Migration Control
FluidLoc adds protection against oil and other liquid migration through the cable. This makes the configuration especially attractive for oil-lubricated turbines, compressors, pumps, and other rotating machinery.
Application-Specific Approval Configuration
The RU suffix distinguishes this cable from the more common 00, 05, and CN configurations. Using the correct approval suffix is an important part of maintaining a properly specified installation.
Technical FAQs
1. What is the Bently Nevada 330130-085-13-RU?
It is a 3300 XL Standard Extension Cable with an 8.5-meter length, armored FluidLoc construction, connector protectors, and an RU country-specific approval configuration.
2. How long is the cable?
The nominal cable length is 8.5 meters (27.9 feet). The 085 ordering code identifies this length.
3. What does “13” mean?
The 13 configuration specifies an armored FluidLoc cable with connector protectors. This is one of the more comprehensively protected configurations in the 330130 family.
4. What does “RU” indicate?
The RU suffix identifies a country-specific approval configuration. It should be treated as a distinct ordering configuration rather than automatically equated with the 05 or CN options.
5. What is FluidLoc?
FluidLoc is a cable construction designed to help restrict the migration of oil and other liquids through the cable assembly. It is particularly useful in oil-lubricated machinery installations.
6. Is the 330130-085-13-RU armored?
Yes. The 13 configuration specifically identifies the armored FluidLoc cable version, providing additional mechanical protection around the cable.
7. Does it include connector protectors?
Yes. Connector protectors are included as part of the 13 cable configuration.
8. What is the approximate weight?
The bare cable assembly is approximately 0.29 kg, while comparable 8.5-meter 13-series configurations are commonly listed with a shipping weight of around 2 kg. Shipping weight includes packaging and should not be interpreted as the cable's net weight.
9. What are the important installation dimensions?
Because this is a flexible armored cable assembly, installation planning should focus on the 8.5-meter overall length, cable outside diameter, connector-protector dimensions, minimum bend requirements, and available routing clearance rather than a rectangular product footprint.
10. How does the 330130-085-13-RU differ from 330130-085-13-CN?
Both models use the same 8.5-meter armored FluidLoc cable with connector protectors, but the approval suffix is different. CN identifies a country-specific approval configuration associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking, while RU is a separate country-specific configuration. The correct suffix should therefore be selected according to the certification and project requirements.
