Introduction
The Bently Nevada 330130-045-02-CN is a 3300 XL Standard Extension Cable designed for compatible 3300 XL proximity transducer systems. It provides the connection between a compatible proximity probe and Proximitor Sensor, extending the measurement circuit while preserving the configuration required by the overall proximity monitoring system.
This version uses a 4.5-meter (14.8 ft) cable length, giving it additional routing flexibility for machinery installations where a shorter extension is insufficient. The 02 configuration specifies a standard cable with connector protectors, while the CN approval option is associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking.
The 330130-045-02-CN is therefore more than a simple cable-length extension. Its specific length, connector-protection arrangement, and CN approval configuration make it a defined component within the 3300 XL system. For replacement projects and new installations, matching these characteristics can help avoid unnecessary changes to an established monitoring arrangement.

Applications
Turbine Vibration Monitoring
The 330130-045-02-CN can be incorporated into turbine monitoring systems where proximity probes are used to measure shaft vibration and position. Its 4.5-meter reach provides useful flexibility between field-mounted probes and the associated Proximitor Sensor.
Compressor Monitoring
Large compressors often require instrumentation connections to be routed between bearing housings and equipment-mounted monitoring electronics. The longer extension configuration can simplify cable routing where additional distance is required.
Generator Condition Monitoring
Generators and other large rotating machines can use proximity systems to observe shaft movement and vibration. The 4.5-meter cable offers additional installation reach without moving away from the established 3300 XL architecture.
Oil and Gas Equipment
The CN approval configuration makes this model particularly relevant to projects where the specified installation requires the applicable ATEX/IECEx and Chinese NEPSI hazardous-area marking. The exact certification requirements should always be matched to the equipment documentation and installation zone.
Petrochemical and Process Plants
Continuous machinery monitoring is important in process facilities where rotating assets operate under demanding conditions. A correctly configured extension cable helps maintain the physical connection between the proximity probe and signal-conditioning equipment.
Pumps and Motors
Compatible 3300 XL proximity systems can be used on industrial pumps, motors, and other rotating equipment. The connector-protector configuration is useful in areas where instrumentation connections are routinely accessed during maintenance.
Fluid-Film Bearing Applications
The 3300 XL proximity platform is commonly used for machinery incorporating fluid-film bearings. The extension cable becomes part of the complete electrical path used for dynamic shaft movement and vibration measurements.
Retrofit and Replacement Projects
The 330130-045-02-CN is a strong replacement candidate when an existing installation requires a 4.5-meter standard extension cable with connector protection and the CN approval configuration.
Advantages
4.5-Meter Installation Flexibility
The 4.5-meter length provides greater routing freedom than shorter extension configurations. It can be especially useful when the Proximitor Sensor is installed away from the immediate machinery sensing point.
Connector Protection Included
The 02 option incorporates connector protectors, adding mechanical protection around the connection area. This can be beneficial during installation, inspection, and routine plant maintenance.
CN Approval Configuration
The CN suffix distinguishes this model from standard approval configurations. It is associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking, making the configuration relevant to appropriately specified hazardous-area projects.
75 Ω Triaxial Construction
The 75 Ω triaxial design provides controlled electrical characteristics appropriate to the 3300 XL proximity measurement system.
FEP Insulation
FEP insulation contributes to the cable's suitability for industrial instrumentation applications and provides a robust insulating layer around the cable construction.
Practical Cable Geometry
With a nominal cable weight of approximately 34 g/m and a defined minimum bend radius, the cable remains manageable for routing around industrial machinery and instrumentation panels.
Defined System Compatibility
The model is purpose-built for the 3300 XL proximity transducer architecture, helping maintenance teams select a component that belongs to the same established measurement platform.
Reduced Replacement Risk
The complete part number identifies the cable length, connector configuration, and approval option. This makes the 330130-045-02-CN easier to distinguish from visually similar 330130 variants.
Suitable for Critical Assets
The cable can support monitoring arrangements on turbines, compressors, generators, pumps, and other rotating equipment where reliable proximity-sensor connections are important to machinery protection and condition monitoring.
Professional Retrofit Solution
For an existing 3300 XL installation, replacing a matching cable with the same 045-02-CN configuration can simplify maintenance and reduce the need for unnecessary system modifications.
Technical FAQs
1. What is the Bently Nevada 330130-045-02-CN?
It is a 3300 XL Standard Extension Cable with a 4.5-meter length, standard cable construction, connector protectors, and the CN approval configuration.
2. What does the 045 code mean?
The 045 portion of the part number identifies the 4.5-meter (14.8 ft) cable length.
3. What does the 02 option specify?
The 02 option specifies a standard cable with connector protectors.
4. What does CN mean on this cable?
The CN approval option is associated with ATEX/IECEx and Chinese NEPSI hazardous-area marking. The actual certification applicability should be confirmed against the installation requirements before use.
5. What is the approximate cable weight?
At approximately 34 g/m, the estimated cable-only weight for 4.5 meters is around 0.153 kg. Product listings commonly specify approximately 2 kg shipping weight, which includes packaging.
6. What is the minimum bend radius?
The minimum bend radius is approximately 25.4 mm (1.0 inch). Maintaining the recommended bend radius helps prevent unnecessary mechanical stress during installation.
7. What cable construction does it use?
The standard cable is specified as a 75 Ω triaxial cable with FEP insulation, with typical capacitance of approximately 69.9 pF/m.
8. Can this cable be used with a 3300 XL 8 mm proximity probe?
Yes, when the probe, extension cable, and Proximitor Sensor are configured as a compatible 3300 XL proximity transducer system. The total probe-plus-extension length must also correspond to the required system configuration.
9. Why choose the CN version instead of the 00 version?
The CN version is intended for projects requiring the applicable ATEX/IECEx and Chinese NEPSI hazardous-area marking. The 00 version does not provide the same CN approval configuration, so the two should not be treated as interchangeable solely because both are 4.5-meter cables.
10. What should be checked before ordering?
Confirm the 4.5-meter length, 02 connector-protector option, CN approval requirement, connected probe, Proximitor Sensor, total system length, and hazardous-area certification requirements. Matching the complete configuration is essential when replacing a cable in an existing protection or monitoring system.
