Introduction
The Bently Nevada 330130-070-00 is a 7.0-meter 3300 XL Standard Extension Cable designed to provide additional connection distance within compatible 3300 XL proximity measurement systems. Its standard, non-armored configuration makes it a practical option for installations where the cable can be routed through a protected environment without requiring additional mechanical armor.
The 070 length designation identifies the nominal 7.0-meter (22.9-foot) cable option. The 00 cable configuration represents the standard cable arrangement, while the part-number format supplied for this model does not specify an additional agency-approval suffix. Bently Nevada's 3300 XL ordering information confirms 7.0 meters as an available standard extension-cable length and emphasizes that the probe and extension-cable lengths must be matched to the required Proximitor® sensor total length.
With its longer reach and compact profile, the 330130-070-00 is a sensible choice for machinery layouts where shorter extension cables do not provide enough routing flexibility. It can support proximity-based monitoring arrangements on turbines, compressors, pumps, motors, and other rotating assets where dependable signal transmission is essential.

Applications
Extended Machinery Monitoring
The 7-meter configuration provides additional reach for proximity measurement systems installed on machinery where the physical distance between the probe location and monitoring electronics exceeds the practical range of shorter cables.
Turbine Monitoring
Steam and gas turbines can require carefully routed proximity cables around bearing housings and other machinery structures. The 330130-070-00 offers a longer standard cable option for suitable protected routes.
Compressor Applications
In centrifugal compressors and similar rotating equipment, proximity probes are commonly positioned near bearings or shafts while the monitoring electronics are located elsewhere. A 7-meter extension can provide useful installation flexibility without introducing an armored cable configuration.
Pump and Motor Systems
The cable can be used in compatible 3300 XL arrangements for monitoring rotating machinery such as pumps, motors, generators, and related equipment.
Retrofit and Maintenance Projects
When an existing system has been designed around a 7-meter extension cable, using the matching part number can simplify replacement work. Maintaining the original cable length and configuration is preferable to selecting a visually similar cable based only on connector compatibility.
Protected Instrumentation Routes
The standard unarmored construction is most appropriate where the cable can be routed through protected trays, conduits, instrument panels, or other areas with limited exposure to mechanical damage.
Advantages
Seven-Meter Reach
The 7.0-meter length provides a useful step up from shorter extension options and can solve routing challenges without unnecessarily selecting a much longer cable. It is particularly practical for equipment layouts with moderate separation between sensing and monitoring locations.
Slim Cable Profile
With a maximum outside diameter of approximately 3.7 mm, the standard cable has a relatively small installation footprint. This helps simplify routing around crowded machinery, cable trays, junction points, and instrument enclosures.
Proven 3300 XL Configuration
The 330130 family is specifically structured around the 3300 XL proximity measurement architecture. Using the appropriate extension cable helps maintain the intended electrical relationship between the proximity probe, extension cable, and Proximitor® sensor.
Reliable Signal Path
The 75-ohm cable construction and defined capacitance characteristics are designed for the signal-transmission requirements of the 3300 XL proximity system. This makes the correct cable configuration important when maintaining measurement-system performance.
Convenient for Protected Installations
Where armor is not necessary, the standard configuration avoids the additional diameter and weight of armored alternatives. This can make installation cleaner and more manageable.
Useful Maintenance Spare
The clearly identified 7-meter configuration makes the 330130-070-00 a practical spare-part choice for plants operating established 3300 XL monitoring systems. Keeping the exact configuration available can help reduce replacement time during scheduled maintenance.
Flexible Equipment Layout
The additional cable length gives maintenance and engineering teams more freedom when positioning monitoring electronics or routing cables around large machinery. This can be especially helpful when existing equipment layouts cannot be modified easily.
Technical FAQs
1. What is the Bently Nevada 330130-070-00?
The 330130-070-00 is a 3300 XL Standard Extension Cable with a nominal length of 7.0 meters. It uses the standard, non-armored cable configuration.
2. How long is the 330130-070-00?
The cable is 7.0 meters (22.9 feet) long. The “070” portion of the model number identifies the cable-length option.
3. Is the 330130-070-00 an armored cable?
No. The 00 cable option represents the standard cable configuration. Armored versions use a different cable-option designation.
4. What is the approximate diameter of the cable?
The standard 3300 XL extension cable has a maximum outside diameter of approximately 3.7 mm (0.15 in).
5. What type of cable is used?
The 3300 XL extension cable uses a 75-ohm triaxial cable construction designed for the associated proximity measurement system.
6. What is the approximate capacitance?
The typical capacitance is approximately 69.9 pF/m, a characteristic that forms part of the electrical design of the 3300 XL proximity measurement system.
7. What is the approximate weight of the 330130-070-00?
The physical cable weight is approximately 0.24 kg, although actual supplied and shipping weight may vary depending on the complete assembly and packaging.
8. Can this cable be used with a 3300 XL 8 mm proximity probe?
It can be used as part of a compatible 3300 XL 8 mm proximity transducer arrangement, provided the probe, extension cable, and Proximitor® sensor are correctly matched as a complete system.
9. Why is cable length important in a 3300 XL system?
The extension-cable length and probe length are designed to add together to match the required total length of the associated Proximitor® sensor. Selecting an extension cable solely by physical reach can therefore result in an incorrect system configuration.
10. What should be checked before ordering the 330130-070-00?
Verify the complete part number, required 7-meter length, standard cable construction, connector configuration, applicable approval requirements, compatible probe, Proximitor® sensor, and total electrical system length. If the cable will be installed in an exposed or mechanically demanding route, an armored configuration may be more appropriate.
