Introduction
The Bently Nevada 330130-045-12-00 is a 3300 XL Standard Extension Cable configured for applications where a conventional extension cable needs additional protection against fluid migration and contamination around the connector interface.
This model provides a 4.5-meter (14.8 ft) extension length and uses the FluidLoc® cable with connector protectors configuration. The 045 portion identifies the cable length, 12 specifies the FluidLoc® cable with connector protectors, and the final 00 indicates that no additional agency approval option is required.
FluidLoc® is the key feature that distinguishes this model from standard 3300 XL extension cables. It is designed to reduce the possibility of oil or other liquids migrating through the cable interior, while the connector protector adds environmental protection at the connection point. This makes the 330130-045-12-00 an attractive choice for machinery installations where lubrication oil, moisture, or other industrial fluids are practical concerns.
With its defined 4.5-meter length and protected connection configuration, the cable is suitable for replacement, retrofit, and new installation projects involving compatible 3300 XL proximity transducer systems.

Applications
Turbine Instrumentation
The 330130-045-12-00 is a practical choice for turbine proximity-monitoring installations where cables may be exposed to lubrication oil or other fluids. The FluidLoc® construction provides an additional level of protection within the cable assembly.
Compressor Monitoring
Compressor trains frequently place proximity probes near bearings and rotating shafts while signal-conditioning equipment is installed farther away. The 4.5-meter length provides useful routing flexibility, while FluidLoc® helps address fluid-exposure concerns.
Generator Shaft Monitoring
The cable can be incorporated into compatible 3300 XL proximity systems used for shaft vibration and position monitoring on generators. Its protected connector arrangement can be particularly useful in equipment areas subject to routine maintenance.
Oil and Gas Equipment
Oil and gas machinery can operate in environments where cable integrity and resistance to fluid migration are important. The FluidLoc® configuration offers a purpose-designed solution for appropriately specified proximity-monitoring applications.
Petrochemical Plants
Pumps, compressors, turbines, and other rotating assets in petrochemical facilities can benefit from robust sensor connections. The combination of FluidLoc® and connector protection makes this cable well suited to applications where oil or process-fluid exposure must be considered.
Pump and Motor Monitoring
The cable can be used with compatible 3300 XL proximity systems installed on industrial pumps and motors. The 4.5-meter reach allows monitoring electronics to be positioned away from the immediate sensing location.
Bearing Monitoring
Where proximity probes are installed around bearing housings, the cable route may encounter lubricants and other contaminants. The FluidLoc® configuration provides an advantage over a basic standard extension cable in such environments.
Machinery Protection Systems
The extension cable forms part of the signal path between the proximity probe and Proximitor Sensor. Maintaining the correct cable configuration helps preserve the intended characteristics of the complete measurement system.
Retrofit and Replacement Projects
For an existing 3300 XL installation requiring a 4.5-meter FluidLoc® cable with connector protectors, the 330130-045-12-00 provides a direct configuration match and avoids substituting a cable with different environmental characteristics.
Advantages
FluidLoc® Protection
The defining feature of the 12 configuration is FluidLoc®. This construction is designed to reduce oil and liquid migration through the internal cable structure, providing an important benefit in machinery environments where fluid exposure is possible.
Integrated Connector Protection
The cable includes connector protectors, giving the connection area additional environmental protection. This makes the 12 configuration different from the 11 version, which provides FluidLoc® and armoring without the same connector-protector arrangement.
4.5-Meter Reach
The 4.5-meter length offers a useful middle ground for installations requiring more reach than shorter configurations without moving to a significantly longer cable.
75 Ω Triaxial Construction
The 75 Ω triaxial construction is designed for the electrical requirements of compatible 3300 XL proximity transducer systems.
FEP Insulation
FEP insulation contributes to the cable's suitability for demanding industrial instrumentation applications and provides a stable insulating layer around the conductors.
Protection Against Fluid Migration
FluidLoc® addresses an important failure consideration in proximity-monitoring installations: unwanted liquid migration through the cable. This is especially relevant around lubricated rotating machinery.
Protected Connection Interface
The connector-protector arrangement adds a physical barrier around the connector interface, helping reduce exposure to contamination, moisture, and routine handling.
Compact Cable Construction
Despite the additional FluidLoc® features, the cable maintains a relatively compact profile, with a maximum FluidLoc® cable diameter of approximately 3.9 mm.
Clear Configuration Identification
The part number provides a simple way to distinguish this version:
- 330130 — 3300 XL Standard Extension Cable
- 045 — 4.5-meter cable length
- 12 — FluidLoc® cable with connector protectors
- 00 — Additional agency approval not required
Strong Choice for Oil-Exposed Installations
When fluid protection is more important than mechanical armoring, the 330130-045-12-00 offers a particularly well-balanced configuration. It provides FluidLoc® and connector protection without adding the full armored construction of the 11 or 13 configurations.
Technical FAQs
1. What is the Bently Nevada 330130-045-12-00?
It is a 3300 XL Standard Extension Cable with a 4.5-meter length, FluidLoc® cable construction, connector protectors, and no additional agency approval option.
2. How long is the 330130-045-12-00?
The cable is 4.5 meters (14.8 feet) long. The 045 code identifies the cable length.
3. What does the 12 configuration mean?
The 12 option specifies a FluidLoc® cable with connector protectors.
4. What is FluidLoc® used for?
FluidLoc® is designed to help prevent or reduce the migration of oil and other liquids through the interior of the cable. This is particularly valuable in machinery environments where lubrication fluids may be present.
5. Does this cable have armor?
No. The 12 configuration provides FluidLoc® and connector protection but does not use the armored construction found in configurations such as 11 or 13.
6. What is the difference between 330130-045-12-00 and 330130-045-11-00?
Both models use FluidLoc® construction, but 330130-045-11-00 adds armoring without the connector-protector configuration, while 330130-045-12-00 provides FluidLoc® with connector protectors without armor. The choice depends on whether fluid protection, mechanical protection, or connector protection is the primary requirement.
7. What is the approximate weight?
The cable-only weight is approximately 0.153 kg, based on the published 34 g/m nominal cable weight. Some suppliers list approximately 2 kg shipping weight, which includes packaging.
8. What are the electrical characteristics?
The cable has a nominal capacitance of approximately 69.9 pF/m. Published specifications also identify nominal center-to-center and outer-to-outer resistance values of approximately 0.99 Ω and 0.30 Ω, respectively, for the 4.5-meter configuration.
9. Can it be used with a 3300 XL 8 mm proximity probe?
Yes, provided the probe, extension cable, and Proximitor Sensor form a compatible 3300 XL proximity transducer system. The total probe-plus-extension length should also be matched to the required system configuration.
10. When should the 330130-045-12-00 be selected?
It is a strong option when the installation requires a 4.5-meter extension, FluidLoc® protection, and connector protection, but does not require armored cable construction. For applications exposed to significant mechanical hazards, an armored FluidLoc® configuration may be more appropriate.
