Introduction
The Bently Nevada 330130-045-12-CN is a 3300 XL Standard Extension Cable configured for demanding proximity-monitoring installations where FluidLoc protection, connector protection, and country-specific approval requirements are important.
With a nominal length of 4.5 m (14.8 ft), this extension cable provides the required connection between a compatible 3300 XL proximity probe and Proximitor Sensor. The 12 cable option identifies FluidLoc cable with connector protectors, while the CN suffix identifies the country-specific approval configuration. This makes the model particularly relevant for projects where the standard approval options are not the preferred certification arrangement.
The FluidLoc construction is an important feature of this configuration. It is designed to help prevent oil and other liquids from migrating through the cable, making it a strong choice for rotating machinery installations exposed to lubrication oil, process fluids, or other industrial contaminants.
The 330130-045-12-CN is therefore best viewed as a complete system component rather than a generic extension lead. Its electrical characteristics, physical length, connector configuration, and approval option all contribute to correct integration within a 3300 XL proximity transducer system.
Technical Specifications
The part number can be interpreted through the 3300 XL ordering structure: 330130 identifies the standard extension cable family, 045 indicates a 4.5-meter cable, 12 specifies FluidLoc cable with connector protectors, and CN identifies the country-specific approval option. The CN option is specifically documented as a country-specific approvals configuration.

Applications
Turbine Machinery Monitoring
The 330130-045-12-CN can be incorporated into compatible proximity measurement channels on steam and gas turbines. The 4.5-meter length provides practical routing flexibility between the sensing point and the Proximitor location.
Compressor Protection
Compressors can operate in environments where oil, process fluids, vibration, and restricted installation spaces are common. The FluidLoc construction provides an additional advantage where fluid migration through the cable is a concern.
Generator Shaft Monitoring
Generators may use proximity probes around bearing housings and shaft locations to monitor relative shaft vibration or displacement. The extension cable allows the probe to remain close to the measurement point while the Proximitor is located at a more accessible position.
Pump and Motor Monitoring
Industrial pumps, motors, fans, and other rotating assets can use compatible 3300 XL proximity systems for condition monitoring. The 4.5-meter cable provides useful installation reach without requiring a longer cable configuration.
Bearing Vibration Measurement
When combined with a compatible 3300 XL proximity probe and Proximitor Sensor, the cable forms part of the signal path used for relative shaft vibration and displacement measurements.
Axial Position Applications
Compatible proximity transducers can also be used for axial-position monitoring. In these installations, the extension cable provides the physical and electrical connection between the field-mounted probe and the Proximitor.
Oil-Exposed Installations
FluidLoc is particularly useful where instrumentation cables are exposed to turbine oil, lubrication systems, or other liquids. The construction is intended to help prevent liquids from traveling through the cable interior.
Country-Specific Certified Projects
The CN approval configuration is intended for projects requiring the applicable country-specific certification arrangement rather than simply selecting the standard multiple-approval suffix. The exact certification and installation requirements should be confirmed against the project documentation before use.
Advantages
FluidLoc Cable Construction
The defining feature of the -12 configuration is FluidLoc. It provides an additional barrier against oil and liquid migration, making it well suited to machinery areas where conventional cable construction may face greater environmental exposure.
Connector Protectors Included
The 12 configuration includes connector protectors, adding protection to the connection area and helping support reliable installation in industrial machinery environments.
Practical 4.5-Meter Reach
At 4.5 m / 14.8 ft, the cable offers a balanced solution for installations where the probe and Proximitor Sensor are separated by several meters.
75 Ω Triaxial Construction
The 75 Ω triaxial cable construction is designed for the electrical requirements of the 3300 XL proximity transducer system. Correct cable selection helps maintain the intended electrical characteristics of the complete measurement chain.
Country-Specific Approval Option
The CN suffix makes this model different from the commonly encountered -05 multiple-approval configuration. It is intended for country-specific approval requirements, giving project engineers a more targeted ordering option.
Compact Cable Profile
With a FluidLoc cable diameter of approximately 3.94 mm maximum, the cable can be routed through many relatively confined machinery areas while retaining its specialized fluid-protection design.
Reduced Fluid-Migration Risk
For oil-rich environments, FluidLoc construction can provide an important practical advantage by limiting the movement of liquids through the cable.
Defined Electrical Length
The cable is designed to be used as part of a matched probe-extension-Proximitor system. This is particularly important because the physical cable length is only one part of the overall electrical configuration.
Suitable for Critical Machinery
The combination of FluidLoc construction, connector protection, and a defined approval configuration makes the cable an attractive option for critical rotating-equipment monitoring projects.
Technical FAQs
1. What is the Bently Nevada 330130-045-12-CN?
It is a 3300 XL Standard Extension Cable with a 4.5-meter length, FluidLoc cable construction, connector protectors, and a country-specific approval configuration.
2. How long is the 330130-045-12-CN?
The nominal length is 4.5 meters (14.8 feet). The 045 portion of the ordering code identifies this cable length.
3. What does the “12” option mean?
The 12 option identifies FluidLoc cable with connector protectors. This distinguishes it from standard, armored, and other 330130 configurations.
4. What does “CN” mean?
The CN suffix identifies a country-specific approval configuration. It is different from the 05 multiple-approval option and should be selected according to the certification requirements of the intended installation.
5. Is the 330130-045-12-CN an armored cable?
No. The 12 configuration is FluidLoc cable with connector protectors. Armored FluidLoc cable with connector protectors is a different configuration within the 330130 family.
6. What is FluidLoc used for?
FluidLoc is intended to help prevent oil and other liquids from migrating through the cable. This makes it particularly useful around lubricated machinery and other installations where fluid exposure is a concern.
7. What are the cable dimensions?
The FluidLoc cable has a maximum outside diameter of approximately 3.94 mm. The standard 330130 cable is approximately 3.7 mm maximum diameter. Connector protectors are larger and need additional clearance during installation.
8. What is the approximate weight?
The extension-cable family is approximately 34–37 g/m, depending on the configuration. A 4.5-meter cable therefore has an estimated cable-only mass of approximately 0.15–0.17 kg, excluding connector hardware, protectors, and packaging.
9. What is the minimum bend radius?
The specified minimum bend radius is 25.4 mm (1.0 inch). Avoiding tighter bends helps reduce mechanical stress on the cable and connector transitions.
10. Can the 330130-045-12-CN replace the 330130-045-12-05?
Not automatically. Both use a 4.5-meter FluidLoc cable with connector protectors, but the approval configuration is different: -05 identifies multiple approvals, while -CN identifies country-specific approvals. The replacement should therefore be selected according to the actual certification and project requirements.
