Introduction
The Bently Nevada 330130-130-02-05 is a 3300 XL Standard Extension Cable intended for use in compatible 3300 XL 8 mm proximity transducer systems. With a nominal 13.0-meter cable length, this configuration is designed for installations where the distance between the proximity probe and Proximitor Sensor exceeds the reach of shorter standard cable options.
The 3300 XL proximity transducer system uses the probe, extension cable, and Proximitor Sensor as an integrated measurement chain for non-contact shaft vibration and position monitoring. The 330130-130-02-05 provides the additional cable reach required by larger machinery layouts while retaining the electrical characteristics expected by the 3300 XL system.
The 02 configuration incorporates connector protection, while the final 05 approval option is associated with the multiple-approval version. For maintenance, retrofit, and new installation projects, matching the complete part number is important because apparently similar 330130 cables can differ in length, connector protection, cable construction, and certification configuration.

Applications
Large Turbine Installations
The 13-meter cable length is particularly useful on large steam and gas turbines where the proximity probe is installed close to the shaft or bearing while the Proximitor Sensor is located farther away in an instrumentation area.
Compressor Monitoring
Large centrifugal and axial compressors may require extended cable routing between machine-mounted probes and signal-conditioning equipment. The 330130-130-02-05 provides substantial additional reach while maintaining the intended 3300 XL measurement architecture.
Generator Shaft Monitoring
The cable can be used in compatible 3300 XL systems for monitoring generator shaft vibration and position. Its long reach helps accommodate equipment layouts where the monitoring electronics cannot be located close to the machine.
Motor and Auxiliary Machinery
Large motors, pumps, fans, blowers, and other rotating equipment can benefit from proximity-based vibration and position monitoring. A 13-meter extension can simplify routing where conventional shorter cable lengths are insufficient.
Power Generation Plants
In power-generation environments, machinery protection systems often have considerable physical separation between rotating equipment and control or instrumentation cabinets. The extended length of this cable provides useful installation flexibility.
Oil and Gas Equipment
The cable can be incorporated into compatible machinery-monitoring installations on compressors, turbines, pumps, and other rotating equipment used in oil and gas facilities, subject to the applicable system and certification requirements.
Retrofit and Replacement Work
For an existing installation specified for a 13-meter 3300 XL extension cable with connector protection and the 05 approval configuration, the complete 330130-130-02-05 part number provides a precise replacement reference.
Advantages
13-Meter Reach
The biggest practical advantage is the 13.0-meter cable length. It provides significantly more routing freedom than the shorter cable options commonly used in compact machinery installations.
Connector Protection
The 02 configuration incorporates a connector protector, adding physical protection around the cable termination. This can be valuable during installation and maintenance, especially where the connector is exposed to handling or surrounding equipment.
3300 XL Electrical Compatibility
The extension cable is intended to work within the 3300 XL proximity transducer architecture. Maintaining the intended cable characteristics is important for preserving the performance of the probe-extension cable-Proximitor Sensor measurement chain.
75Ω Triaxial Construction
The 75Ω triaxial cable design provides a defined electrical interface for the compatible proximity system. Its typical capacitance of approximately 69.9 pF/m is an important system parameter when determining total cable length and configuration.
FEP Insulation
FEP insulation supports dependable electrical isolation in industrial environments and contributes to the durability of the instrumentation cable.
Cleaner Routing Than Armored Variants
The 02 configuration is a standard cable with connector protection rather than an armored configuration. Where the cable route is adequately protected from mechanical damage, this can provide a simpler and more flexible installation.
Long-Distance Instrumentation Connection
The 13-meter length is especially attractive when the Proximitor Sensor must be located in a safer, more accessible, or more centralized instrumentation area rather than directly beside the rotating machine.
Established 3300 XL Platform
The 3300 XL proximity transducer system is widely used for monitoring static shaft position and dynamic vibration. The extension cable is one of the essential components in creating the complete measurement path.
Technical FAQs
1. What is the Bently Nevada 330130-130-02-05?
It is a 3300 XL Standard Extension Cable configured with a nominal 13.0-meter length, connector protection, and the 05 approval configuration.
2. How long is the 330130-130-02-05?
The nominal cable length is 13.0 meters, equivalent to approximately 42.7 feet.
3. What does “130” mean?
The 130 length code identifies the 13.0-meter extension cable configuration.
4. What does “02” mean?
The 02 configuration identifies the standard cable with connector protection. This distinguishes it from cable versions without connector protection and from configurations using armored or FluidLoc construction.
5. What does the final “05” indicate?
The final 05 identifies the multiple-approval configuration. The exact certification requirements of the installation should always be checked before substitution.
6. Is the 330130-130-02-05 an armored cable?
No. The 02 configuration is a standard cable with connector protection. It should not be treated as equivalent to an armored 330130 configuration.
7. Does this cable use FluidLoc?
The 02 configuration is not the FluidLoc option. If oil-migration protection is specifically required, the appropriate FluidLoc configuration should be selected rather than substituting a standard 02 cable.
8. What is the cable capacitance?
The typical extension-cable capacitance is approximately 69.9 pF/m (21.3 pF/ft). This characteristic is relevant to the overall electrical behavior of the 3300 XL proximity measurement system.
9. What are the physical dimensions and weight?
The principal physical dimension is the 13.0-meter overall cable length. Because the cable is flexible, it does not have a fixed rectangular footprint. A reasonable bare-cable mass estimate is approximately 0.44 kg, although actual supplied weight can vary according to the finished assembly and packaging.
10. When should I choose the 330130-130-02-05 instead of a shorter cable?
The 330130-130-02-05 is most useful when the installation requires approximately 13 meters of routing distance between the proximity probe and Proximitor Sensor. If the cable path is substantially shorter, a shorter 330130 configuration may provide easier handling and more efficient installation.
