Introduction
The Bently Nevada 330130-085-02-00 is a 3300 XL Standard Extension Cable configured with an 8.5-meter cable length and standard cable construction with connector protectors. Developed for compatible 3300 XL proximity transducer systems, it provides a dependable connection between the proximity probe and Proximitor Sensor while giving engineers greater freedom when routing instrumentation around large rotating machines.
The 8.5-meter configuration is particularly useful when the measurement point and monitoring electronics are separated by a substantial physical distance. Unlike the basic standard cable configuration, this model incorporates connector protectors to provide additional protection around the connection points, making it a practical choice for installations where cable-end durability deserves extra attention.
The final -00 ordering option indicates that no special agency approval is required for this configuration. For standard industrial machinery monitoring projects where additional certification is not part of the equipment specification, the 330130-085-02-00 offers a straightforward and cost-effective extension solution.

Applications
Rotating Machinery Protection
The 330130-085-02-00 is designed to form part of a proximity measurement circuit used for monitoring critical rotating machinery. It can be incorporated into systems measuring shaft vibration, radial position, axial position, or other machine-dynamic parameters.
Turbine Monitoring
Large steam and gas turbines can require considerable cable routing distance between the proximity probe installed at the machine and the monitoring electronics. The 8.5-meter length provides useful installation flexibility while keeping the system based on the standard 3300 XL architecture.
Compressor Applications
For compressors and other large rotating assets, maintaining a reliable signal path from the measurement point to the Proximitor Sensor is essential. The extended cable length can simplify cabinet placement and field routing.
Pump and Motor Monitoring
The cable can be used in compatible proximity-based monitoring arrangements for industrial pumps, motors, and other rotating equipment where shaft movement and vibration are important operating indicators.
Machinery Condition Monitoring
The 3300 XL system is commonly applied where continuous measurement is required to support machinery protection and condition monitoring. The extension cable forms an essential part of the electrical path between the sensing element and signal-conditioning equipment.
Maintenance and Retrofit Work
The 330130-085-02-00 is also a useful replacement option for existing installations that specifically require an 8.5-meter standard cable with connector protectors. Matching the complete part number helps avoid unnecessary changes to the established installation.
Advantages
Extended 8.5-Meter Installation Range
The 8.5-meter length provides generous routing distance for large machines and distributed monitoring cabinets. It can make installation planning easier where the probe and Proximitor Sensor cannot be positioned close together.
Added Connector Protection
The defining feature of the -02 configuration is its connector-protector arrangement. Protecting the cable connection points can help reduce the risk of accidental mechanical damage during installation, maintenance, and equipment servicing.
Standard Cable Construction
This model uses the standard cable configuration rather than an armored version. That makes it an attractive choice for controlled cable routes where additional armor is unnecessary and a simpler installation is preferred.
75Ω Triaxial Design
The 75Ω triaxial construction is intended for the electrical requirements of the 3300 XL proximity measurement system. Its defined cable characteristics help maintain a predictable signal path between compatible system components.
FEP Insulation
FEP insulation provides a robust insulating material for industrial instrumentation applications and is well suited to the environmental demands associated with machinery monitoring systems.
Practical Replacement Configuration
Because the ordering code clearly identifies the cable length and connector-protector configuration, maintenance personnel can more easily identify a like-for-like replacement when servicing an installed 3300 XL system.
No Special Agency Approval Required
The final -00 option indicates that no agency approval is required for this specific configuration. For standard industrial applications where additional certification is not specified, this can simplify component selection.
Balanced Cost and Protection
The 330130-085-02-00 sits between a basic standard cable and more heavily protected armored configurations. It provides additional protection at the connector area without adding the full construction of an armored cable.
Technical FAQs
1. What is the Bently Nevada 330130-085-02-00?
The 330130-085-02-00 is a 3300 XL Standard Extension Cable used in compatible Bently Nevada proximity transducer systems. It features an 8.5-meter cable length and standard cable construction with connector protectors.
2. How long is the 330130-085-02-00?
The cable length is 8.5 meters, equivalent to approximately 27.9 feet.
3. What does the “085” designation mean?
The 085 portion of the ordering number identifies the 8.5-meter cable-length option.
4. What does “02” mean?
The 02 option specifies a standard cable with connector protectors. This provides additional protection around the cable connection points compared with the basic standard cable configuration.
5. What does the final “00” mean?
The final 00 identifies the agency approval option. For this model, no special agency approval is required.
6. What type of cable construction is used?
The 330130-085-02-00 uses a 75Ω triaxial cable with FEP insulation. The cable is configured with standard connector protectors rather than an armored outer construction.
7. What is the approximate weight?
The listed cable weight is approximately 0.034 kg per meter. For an 8.5-meter cable, this corresponds to approximately 0.289 kg.
8. Is this cable compatible with 3300 XL 8 mm proximity systems?
Yes. It is part of the 3300 XL Standard Extension Cable family intended for compatible proximity transducer system configurations. The probe, extension cable, and Proximitor Sensor combination should be checked as a complete system.
9. How is the 330130-085-02-00 different from 330130-085-00-00?
Both models use an 8.5-meter standard cable configuration, but the -02-00 version includes connector protectors. The -00-00 configuration is the standard cable without the connector-protector option.
10. How should the cable length be selected for a 3300 XL system?
The extension cable length and probe length should be selected so that their combined length matches the required Proximitor Sensor system length. This is an important part of maintaining the intended electrical characteristics of the complete proximity transducer system.
