Introduction
The Bently Nevada 330130-085-00-02 is a 3300 XL Standard Extension Cable configured with an 8.5-meter (27.9 ft) cable length and a standard cable arrangement with the 00-02 configuration.
Designed for use within compatible 3300 XL proximity transducer systems, this extension cable provides the additional reach needed when a proximity probe is installed at a significant distance from its associated Proximitor Sensor. The 8.5-meter length makes it particularly useful on large rotating machinery where shorter extension cables may not provide sufficient routing flexibility.
The 085 designation identifies the 8.5-meter cable length. The 00-02 configuration represents a standard extension-cable arrangement without the armored or FluidLoc® construction associated with other 3300 XL variants. For applications where a relatively compact and flexible cable is preferred, this configuration can be an efficient choice.
Its combination of long reach, standard construction, compact routing characteristics, and compatibility with the 3300 XL monitoring architecture makes the 330130-085-00-02 a practical option for turbines, compressors, generators, pumps, and other critical rotating assets.

Applications
Turbine Shaft Monitoring
Large steam and gas turbines often have substantial distances between proximity probes and monitoring electronics. The 8.5-meter cable gives installers more freedom to route the signal around bearing housings, machine structures, and instrumentation pathways.
Compressor Trains
Compressor systems can contain multiple monitoring points distributed along a long machine train. The extended cable length can help connect probe locations with remotely positioned Proximitor Sensors without resorting to shorter cable combinations.
Generator Monitoring
For generators and large rotating electrical machines, proximity probes are commonly positioned around shafts and bearings. An 8.5-meter extension provides useful reach when the associated electronics are mounted outside the immediate machine area.
Pump and Motor Applications
Compatible 3300 XL proximity-monitoring systems can be used on critical pumps and motors. The standard cable construction provides a practical connection where heavy mechanical armoring is not necessary.
Bearing Vibration Monitoring
The cable can form part of a proximity measurement chain used to monitor shaft movement relative to bearing housings. Correct probe and cable selection is important because the extension cable contributes to the electrical characteristics of the overall system.
Machinery Protection
The 330130-085-00-02 can be incorporated into a complete machinery-protection arrangement where continuous shaft vibration or position measurements are required.
Industrial Process Equipment
Large process machinery may have sensors installed in locations that are physically separated from instrumentation cabinets. The 8.5-meter reach allows cable routing to accommodate larger equipment layouts while retaining a compact cable profile.
Retrofit Installations
When an existing 3300 XL installation specifies an 8.5-meter standard extension cable, maintaining the same complete part number can simplify replacement work and reduce the risk of selecting a cable with the wrong length or physical configuration.
Space-Constrained Routing
Because the standard cable has a relatively small outside diameter, it can be easier to route through narrow instrumentation pathways than armored alternatives. This can be useful around crowded machine assemblies and control-panel entry points.
Advantages
Extended 8.5-Meter Reach
The primary advantage is the 8.5-meter length, providing greater installation flexibility than the more common 3-to-8-meter configurations. It is well suited to large machines where the sensing point and monitoring electronics are separated by considerable distance.
Compact Standard Construction
Unlike armored cable configurations, the standard construction maintains a relatively small cable profile. This makes it easier to route through restricted spaces and can reduce installation complexity.
75 Ω Triaxial Design
The 75 Ω triaxial architecture is intended for the signal requirements of the 3300 XL proximity transducer system, helping maintain the expected electrical characteristics of the probe-to-Proximitor connection.
FEP Insulation
FEP insulation provides a durable insulating material for industrial instrumentation applications and supports stable operation in demanding machinery-monitoring environments.
Flexible Cable Routing
The standard cable construction is easier to bend and route than heavier armored alternatives, making it a practical choice when the installation environment does not require additional mechanical protection.
Long-Reach Replacement Option
For maintenance teams replacing an existing 8.5-meter 3300 XL extension cable, the exact 330130-085-00-02 configuration provides a straightforward way to preserve the original cable-length arrangement.
Reduced Installation Bulk
The standard approximately 3.7 mm maximum cable diameter is advantageous in crowded instrumentation areas. It can help installers maintain cleaner routing paths without adding the bulk associated with armored cable.
Suitable for Distributed Monitoring
Large turbines, compressors, and generators may have monitoring electronics installed at centralized locations. The 8.5-meter cable provides a useful bridge between remote sensing points and those electronics.
Straightforward Identification
The main model-number elements make the basic configuration easy to recognize:
- 330130 — 3300 XL Standard Extension Cable
- 085 — 8.5-meter cable length
- 00-02 — Standard cable configuration
This is helpful for spare-parts inventory and replacement planning.
Practical Balance of Reach and Flexibility
The model offers a useful middle ground for installations that need a longer cable but do not require the additional mechanical protection of armored or FluidLoc® constructions.
Technical FAQs
1. What is the Bently Nevada 330130-085-00-02?
The 330130-085-00-02 is a 3300 XL Standard Extension Cable with an 8.5-meter length and standard cable construction.
2. How long is the 330130-085-00-02?
It is approximately 8.5 meters (27.9 feet) long. The 085 portion of the model number identifies the cable length.
3. What type of cable construction does it use?
The cable uses a 75 Ω triaxial construction with FEP insulation, intended for use in compatible 3300 XL proximity transducer systems.
4. Is this cable armored?
No. The 00-02 configuration is a standard cable arrangement, rather than one of the armored 01 or 03 configurations.
5. Does the model include FluidLoc®?
The 330130-085-00-02 is a standard cable configuration and should not be confused with the dedicated FluidLoc® variants in the 3300 XL extension-cable family.
6. What is the approximate cable diameter?
The standard 3300 XL cable has a maximum outside diameter of approximately 3.7 mm. This relatively slim profile makes it convenient for compact instrumentation routes.
7. What is the approximate weight?
Using a nominal cable weight of approximately 34 g/m, the bare cable weight for 8.5 meters is approximately 0.289 kg. Actual supplied weight can vary depending on packaging and accessories.
8. Can it be used with a 3300 XL proximity probe?
Yes, when selected as part of a compatible 3300 XL proximity transducer system. The probe, extension cable, and Proximitor Sensor must be matched according to the required total electrical length and system configuration.
9. What is the main advantage of the 8.5-meter length?
The longer cable provides additional routing flexibility on large machinery. It can be particularly useful when the proximity probe is located close to a bearing or shaft while the Proximitor Sensor is installed farther away.
10. What should be checked before ordering?
Verify the complete 330130-085-00-02 part number, 8.5-meter length, cable construction, compatible probe, Proximitor Sensor, total electrical length, and site installation requirements. Do not select the cable based only on physical length.
