Introduction
The Bently Nevada 330130-075-01-05 is a 3300 XL Standard Extension Cable designed to extend the connection between a compatible 3300 XL proximity probe and Proximitor Sensor. With a 7.5-meter (24.6 ft) cable length, this model is intended for installations where the sensing point and signal-conditioning equipment require a longer connection path.
Its configuration is clearly defined by the part number. The 075 designates the 7.5-meter cable length, 01 specifies an armored cable, and 05 identifies the multiple-approval configuration, including CSA, ATEX, and IECEx approvals. This combination makes the model particularly useful for industrial installations where extended cable reach, mechanical protection, and applicable hazardous-area approvals are important considerations.
Unlike a basic unarmored extension cable, the 330130-075-01-05 provides additional protection along the cable route. This makes it a compelling option for machinery installations where cables may be exposed to vibration, abrasion, maintenance activity, or other mechanical influences.
As part of the 3300 XL proximity transducer system, cable selection should always be considered together with the probe and Proximitor Sensor. The combined probe and extension-cable length must correspond to the required total system length for the selected Proximitor Sensor.

Applications
Turbine Monitoring
The 7.5-meter extension length makes the 330130-075-01-05 suitable for turbine installations where proximity probes are installed near bearings or shafts while Proximitor Sensors are located at a greater distance.
The armored construction provides an additional layer of physical protection along the cable route, making it a practical choice for large rotating machinery.
Compressor Trains
Large centrifugal and reciprocating compressor installations can require extended sensor wiring between the machinery and instrumentation area. The 7.5-meter configuration provides greater routing freedom than shorter 3300 XL extension cables.
Generator Condition Monitoring
Generators often have monitoring points distributed across large mechanical assemblies. A longer extension cable can simplify the physical connection between field-mounted proximity probes and the associated signal-conditioning electronics.
Oil and Gas Equipment
The CSA, ATEX, and IECEx approval configuration makes this model relevant to appropriately specified installations where recognized hazardous-area approvals are required. The exact approval applicability should always be matched to the equipment certification and installation requirements.
Petrochemical Machinery
Process plants frequently rely on continuous monitoring of pumps, compressors, turbines, and other critical rotating equipment. The combination of extended reach and armored construction provides a practical cable solution for these environments.
Pumps and Motors
Compatible 3300 XL proximity systems can be used to monitor shaft vibration and position on industrial pumps and motors. The 7.5-meter cable provides additional flexibility where a standard short extension would be insufficient.
Fluid-Film Bearing Applications
The 3300 XL 8 mm proximity transducer system is commonly applied to machinery using fluid-film bearings. The extension cable becomes part of the electrical measurement path between the probe and Proximitor Sensor.
Machinery Protection Systems
In machinery protection applications, the quality and configuration of the sensor connection are important to the complete measurement chain. The armored 330130-075-01-05 helps provide a protected connection between the sensing device and monitoring electronics.
Retrofit and Replacement Work
For existing 3300 XL installations that require a 7.5-meter armored extension cable with the multiple-approval configuration, this model offers a direct and clearly defined replacement option.
Advantages
Extended 7.5-Meter Reach
The primary advantage of the 330130-075-01-05 is its 7.5-meter length. This provides substantially more installation flexibility than the shorter 3.0, 3.5, 4.0, and 4.5-meter configurations.
Armored Cable Construction
The 01 cable option specifies an armored cable, adding mechanical protection to the cable assembly. This makes the configuration particularly attractive where the cable route may be exposed to abrasion, impact, or routine maintenance activity.
Multiple Hazardous-Area Approvals
The 05 approval option is specified for CSA, ATEX, and IECEx approvals. This makes the model a useful choice for installations with applicable international hazardous-area requirements.
75 Ω Triaxial Design
The 75 Ω triaxial cable construction is designed around the electrical requirements of the 3300 XL proximity transducer system, supporting stable signal transmission between the probe and Proximitor Sensor.
FEP Insulation
FEP insulation provides a durable insulating layer suitable for industrial instrumentation applications and contributes to the cable's overall environmental robustness.
Long-Route Installation Flexibility
The 7.5-meter configuration can reduce the need for additional cable junctions or alternative routing arrangements when monitoring electronics are installed farther from the machinery.
Clearly Defined Configuration
Every major feature is encoded in the part number:
- 330130 — 3300 XL Standard Extension Cable
- 075 — 7.5-meter cable length
- 01 — Armored cable
- 05 — Multiple approvals
This makes the model easier to identify during spare-parts planning and replacement procurement.
Suitable for Critical Machinery
The combination of armored construction, extended reach, and defined approval configuration makes this model well suited to critical machinery where dependable sensor connections are part of the overall monitoring strategy.
Practical Replacement Solution
For an existing system using the same 330130-075-01-05 configuration, selecting the matching part number can help maintain the established cable length, mechanical construction, and approval characteristics.
Professional Industrial Installation
The model offers a more purpose-built solution than a generic instrumentation extension lead, particularly where the installation requires a defined 3300 XL system component with armored construction and multiple approval options.
Technical FAQs

The 330130-075-01-05 is a 3300 XL Standard Extension Cable with a 7.5-meter length, armored cable construction, and the multiple-approval option.
2. How long is the 330130-075-01-05?
The cable length is 7.5 meters (24.6 feet). The 075 section of the model number identifies this length option.
3. What does the 01 option mean?
The 01 configuration specifies an armored cable. It provides additional mechanical protection compared with the standard unarmored cable option.
4. What does the 05 option indicate?
The 05 agency approval option identifies the configuration with CSA, ATEX, and IECEx approvals.
5. Is the 330130-075-01-05 suitable for hazardous-area installations?
It is configured with CSA, ATEX, and IECEx approval options, making it applicable to installations where those certifications are required and where the complete system satisfies the relevant hazardous-area requirements. The actual installation classification should always be verified before commissioning.
6. What type of cable construction is used?
The 3300 XL extension cable uses a 75 Ω triaxial cable with FEP insulation. The standard cable has a maximum outside diameter of approximately 3.7 mm, while the armored construction increases the overall protected diameter.
7. What is the approximate weight?
Published supplier specifications list approximately 1 kg as the shipping weight for the 330130-075-01-05. The actual cable assembly weight may vary depending on packaging and supplied configuration.
8. Can this extension cable be used with a 3300 XL 8 mm probe?
Yes, it is intended for compatible 3300 XL proximity transducer systems. The probe length and extension-cable length must be considered together to achieve the correct total system length for the selected Proximitor Sensor.
9. Why choose a 7.5-meter cable?
A 7.5-meter cable is useful when the physical distance between the proximity probe and Proximitor Sensor is greater than the shorter standard cable configurations can accommodate. It can also be selected when a specific total probe-plus-extension length is required.
10. What should be checked before ordering?
Verify the 7.5-meter length, armored 01 configuration, 05 approval option, connected probe, Proximitor Sensor, total system length, and installation certification requirements. Matching the complete configuration is important because visually similar 330130 cables can have different lengths, cable constructions, or approval options.
