Introduction
The Bently Nevada 330130-085-01 is an 8.5-meter 3300 XL Standard Extension Cable configured with armored cable construction for demanding machinery monitoring installations. Designed for the 3300 XL proximity transducer system, it provides the required electrical connection between a compatible proximity probe and Proximitor Sensor while adding an extra layer of mechanical protection around the cable.
The 8.5-meter length makes this model particularly useful for installations where the probe location and monitoring electronics are separated by a considerable distance. Its armored construction is also advantageous in cable routes exposed to vibration, abrasion, pulling forces, or other mechanical stresses commonly encountered around industrial rotating equipment.
For replacement work, system maintenance, and new machinery protection installations, the 330130-085-01 offers a practical combination of extended reach and rugged cable protection without changing the fundamental 3300 XL measurement architecture.

Applications
Turbine and Generator Machinery
The 330130-085-01 can be used as part of proximity measurement systems installed on turbines, generators, and other critical rotating equipment. Its 8.5-meter reach can simplify cable routing where monitoring cabinets are positioned away from the machine.
Compressor Monitoring
Large compressors often require proximity probes to be installed close to the shaft while the associated signal-conditioning equipment is located in a more accessible instrumentation area. The extended cable length provides useful installation flexibility in these layouts.
Pumps and Motors
The cable is suitable for compatible proximity-based monitoring arrangements on industrial pumps, motors, and rotating machinery where shaft position or vibration information is being measured.
Fluid-Film Bearing Applications
3300 XL proximity measurement systems are commonly applied to machinery using fluid-film bearings. The extension cable forms an important part of the signal path between the measurement probe and Proximitor Sensor.
Industrial Machinery Protection
The armored construction makes the 330130-085-01 particularly attractive for cable routes where standard unarmored wiring may be more exposed to mechanical damage. It can be used in machinery monitoring installations where long-term cable integrity is an important maintenance consideration.
Maintenance and Replacement Projects
For an existing 3300 XL installation requiring an 8.5-meter armored extension cable, this configuration provides a direct and practical replacement option when the probe, cable, Proximitor Sensor, and approval requirements are correctly matched.
Advantages
Extended 8.5-Meter Reach
The 8.5-meter cable length provides considerable installation freedom for larger machines and distributed monitoring layouts. It can reduce the need for awkward cable routing or repositioning of monitoring equipment simply to accommodate a shorter extension.
Armored Protection
The -01 configuration is specifically associated with armored cable construction. The armor helps improve resistance to abrasion, crushing, pulling, and general mechanical wear, making it a strong choice for demanding industrial cable routes.
Robust Industrial Construction
The cable is built around a 75Ω triaxial configuration with FEP insulation. This combination provides a controlled signal path while maintaining the mechanical and environmental characteristics expected from an industrial machinery monitoring cable.
Flexible Routing for Large Machinery
Although the cable is mechanically protected, its design remains suitable for practical routing around machinery and through cable-management systems. The specified bend radius should be respected during installation to prevent unnecessary stress.
Predictable Electrical Performance
The defined voltage rating, current rating, insulation resistance, and dielectric strength provide useful electrical characteristics for engineering and maintenance teams evaluating cable suitability.
Easy System Matching
The 330130 series uses a clear part-number structure, allowing engineers to identify the required cable length and construction directly from the ordering code. This simplifies spare-parts selection when maintaining a standardized 3300 XL monitoring system.
Well Suited to Critical Equipment
For turbines, compressors, pumps, motors, and other continuously operating rotating machinery, the cable is more than a simple connection component. It forms part of the measurement chain that carries important proximity signals to the monitoring electronics.
Technical FAQs
1. What is the Bently Nevada 330130-085-01?
The 330130-085-01 is a 3300 XL Standard Extension Cable with an 8.5-meter length and armored cable construction. It is used within compatible Bently Nevada proximity measurement systems.
2. How long is the 330130-085-01?
The cable length is 8.5 meters, equivalent to approximately 27.9 feet.
3. What does “085” mean in the model number?
The 085 identifies the 8.5-meter cable-length option within the 330130 Standard Extension Cable series.
4. What does “01” mean?
The 01 identifies the armored cable configuration. It is different from the standard unarmored cable option and is intended to provide additional mechanical protection.
5. What type of cable construction is used?
The cable uses a 75Ω triaxial construction with FEP insulation and an armored outer configuration.
6. What is the cable diameter?
The listed cable outer diameter is approximately 5.8 mm. The actual dimensional requirements of the complete installed assembly should be considered when planning cable routing.
7. What is the bend radius?
A bend radius of approximately 55 mm is associated with the armored cable configuration. The cable should not be forced into tighter bends during installation.
8. What is the approximate weight?
The cable weight is approximately 34 g/m, resulting in a total cable weight of about 0.289 kg for the 8.5-meter configuration.
9. Does 330130-085-01 include a specific hazardous-area approval?
Not by itself. The 01 portion identifies the armored cable configuration, while the agency approval is identified by the final suffix in the complete ordering number. The complete part number should therefore be confirmed before ordering for hazardous-area applications.
10. How should this cable be matched with a 3300 XL probe and Proximitor Sensor?
The extension cable length and probe length should be selected so that their combined length matches the required Proximitor Sensor system configuration. The cable construction and final approval option should also match the installation requirements.
