Introduction
The Bently Nevada 330130-080-11-05 is a 3300 XL Standard Extension Cable configured for installations that demand 8.0 meters (26.2 ft) of reach, armored construction, FluidLoc® protection, and recognized agency approvals.
This model sits toward the longer end of the standard 3300 XL extension-cable range, making it particularly useful on large rotating machines where the proximity probe is installed close to the monitored shaft while the Proximitor Sensor is located farther away. The 080 code identifies the 8.0-meter cable length, 11 specifies the Armored FluidLoc® cable, and 05 identifies the CSA, ATEX, and IECEx approval configuration.
The combination of armor and FluidLoc® makes this configuration more specialized than a basic extension cable. The armor provides additional mechanical protection, while FluidLoc® is intended to reduce the possibility of oil and other liquids migrating through the cable interior. This is particularly valuable around lubricated machinery and in installations where cable integrity is critical to the overall monitoring system.
With its extended 8-meter reach and approval configuration, the 330130-080-11-05 is a strong choice for turbines, compressors, generators, pumps, and other critical rotating equipment where a protected and appropriately approved signal connection is required.

Applications
Large Steam Turbines
The 8-meter reach is well suited to large turbine installations where proximity probes are positioned around bearings or shafts and the Proximitor Sensor must be installed at a more accessible location.
The armored construction adds mechanical protection, while FluidLoc® provides an additional safeguard against fluid migration through the cable.
Gas Turbine Monitoring
Gas turbines place instrumentation in areas where vibration, maintenance activity, and restricted routing space can create challenges. The 330130-080-11-05 combines long reach with a more robust cable construction for suitable monitoring layouts.
Compressor Trains
Large compressors often require proximity probes around several bearing locations. The extended 8-meter cable can provide greater freedom when routing the signal toward monitoring cabinets or equipment panels.
Generator Shaft Monitoring
Generators may require continuous shaft vibration and position measurements. Where the sensing point and Proximitor Sensor are separated by a substantial distance, an 8-meter extension cable can simplify the physical installation.
Oil and Gas Equipment
Fluid exposure is an important consideration around many oil and gas rotating assets. The FluidLoc® configuration is designed to help prevent oil and other liquids from leaking through the cable interior, while the armored construction provides additional mechanical protection.
Petrochemical Machinery
Pumps, compressors, turbines, and other machinery in petrochemical facilities can benefit from a protected proximity-signal connection. The combination of FluidLoc® and armor gives this model a clear advantage where ordinary cable construction may not be sufficient.
Bearing and Shaft Monitoring
The cable can be incorporated into compatible 3300 XL proximity transducer systems for shaft vibration and position monitoring. Maintaining the correct electrical length across the probe, extension cable, and Proximitor Sensor is essential when configuring the complete system.
Hazardous-Area Installations
The 05 approval option identifies a configuration associated with CSA, ATEX, and IECEx approvals, making this model appropriate for installations where the applicable certification requirements call for these approval schemes. The actual site classification and installation requirements should always be matched to the complete system.
Retrofit and Replacement Work
For an existing 3300 XL system originally specified with an 8.0-meter Armored FluidLoc® cable and 05 approval configuration, matching the complete 330130-080-11-05 part number helps maintain the intended installation characteristics.
Advantages
Extended 8-Meter Reach
At 8.0 meters (26.2 ft), this cable offers substantial routing flexibility for large machinery installations. It is longer than the common 3.0-to-7.5-meter configurations and can reduce the need for alternative cable-routing arrangements.
Armored FluidLoc® Construction
The 11 configuration combines two important protection features: mechanical armoring and FluidLoc®. The armor helps protect the cable from physical damage, while FluidLoc® is intended to limit fluid migration through the cable structure.
Protection Against Oil Migration
FluidLoc® is particularly valuable around machinery where turbine oil, lubrication fluids, or similar liquids may be present. It is designed to prevent oil and other liquids from leaking out through the cable interior.
Strong Mechanical Protection
The armored construction provides an additional protective layer around the cable, helping it withstand installation handling and potential mechanical contact more effectively than a basic unarmored cable.
75 Ω Triaxial Design
The cable uses the 75 Ω triaxial construction associated with the 3300 XL proximity transducer system. This allows the extension cable to form part of a properly matched probe, cable, and Proximitor Sensor combination.
FEP Insulation
FEP insulation provides a robust dielectric material for industrial instrumentation applications and supports the cable's suitability for demanding machinery environments.
International Approval Configuration
The 05 suffix identifies the CSA, ATEX, and IECEx approval configuration. This makes the model especially useful for projects where the applicable installation requires these recognized approval schemes.
No Separate Connector Protector Requirement
The 11 option is defined as an Armored FluidLoc® cable, rather than the connector-protector configurations represented by options 12 and 13. This gives the cable a different physical configuration while retaining robust protection along the cable itself.
Better Fit for Demanding Machinery
For critical rotating equipment, an extension cable is an important part of the measurement chain. Selecting an armored FluidLoc® configuration provides additional protection where cable damage or fluid migration could compromise long-term monitoring reliability.
Simple Part-Number Decoding
The model can be understood directly from its configuration:
- 330130 — 3300 XL Standard Extension Cable
- 080 — 8.0-meter length
- 11 — Armored FluidLoc® cable
- 05 — CSA, ATEX, IECEx approvals
This makes the exact replacement configuration easier to identify during maintenance and spare-parts planning.
Technical FAQs

The 330130-080-11-05 is a 3300 XL Standard Extension Cable with an 8.0-meter length, Armored FluidLoc® construction, and the 05 approval configuration.
2. How long is the cable?
The cable is 8.0 meters (26.2 feet) long. The 080 portion of the model number identifies the cable length.
3. What does the 11 option mean?
The 11 option specifies an Armored FluidLoc® cable. It combines mechanical armoring with FluidLoc® protection.
4. What does the 05 suffix mean?
The 05 agency approval option identifies CSA, ATEX, and IECEx approvals for the applicable configuration.
5. Is the 330130-080-11-05 an armored cable?
Yes. Armoring is an integral part of the 11 cable configuration. The armor provides additional mechanical protection along the cable.
6. What is FluidLoc® used for?
FluidLoc® is designed to help prevent oil and other liquids from migrating through the cable interior. This feature is especially relevant to proximity-monitoring installations around lubricated rotating machinery.
7. Does the 11 configuration include connector protectors?
The 11 option is defined as an Armored FluidLoc® cable, rather than the connector-protected options represented by 12 and 13. The exact connection arrangement should therefore be confirmed against the required system configuration.
8. What is the approximate weight?
Using a nominal cable weight of approximately 34 g/m, an 8-meter cable would weigh about 0.272 kg before packaging. Some supplier listings give approximately 1 kg as shipping weight, which includes packaging and should not be confused with the bare cable weight.
9. Can it be used with a 3300 XL 8 mm proximity probe?
Yes, when the probe, extension cable, and Proximitor Sensor are selected as a compatible 3300 XL proximity transducer system. The electrical lengths of the three components need to be correctly matched.
10. What should be verified before ordering?
Confirm the 8.0-meter length, Armored FluidLoc® configuration, 05 approval option, compatible probe, Proximitor Sensor, total electrical length, and site certification requirements. Matching the full part number is the safest approach for replacement applications.
