Introduction
The Bently Nevada 330130-045-12-05 is a specialized 3300 XL Standard Extension Cable developed for use with compatible 3300 XL proximity transducer systems. With a 4.5 m (14.8 ft) cable length, FluidLoc construction, connector protectors, and a multiple-approval configuration, it provides a dependable connection between the proximity probe and Proximitor Sensor in demanding industrial monitoring applications.
What distinguishes this model from conventional armored 330130 configurations is the FluidLoc cable option. The FluidLoc design is intended to provide enhanced protection against fluid migration through the cable construction, making it a valuable choice where the cable may be exposed to oil, moisture, or other challenging installation conditions.
The 330130-045-12-05 is therefore more than a simple extension lead. It forms an integral part of the 3300 XL proximity measurement chain, where the electrical characteristics and total system length must be correctly matched to the selected probe and Proximitor Sensor.
For maintenance departments and plant engineers, this model offers a purpose-built solution when a 4.5-meter FluidLoc extension cable with connector protection and multiple approvals is required.

Applications
Machinery Shaft Monitoring
The 330130-045-12-05 can be used as part of a 3300 XL proximity measurement channel for monitoring shaft vibration, radial displacement, or axial position on compatible rotating machinery.
Turbine Installations
Steam and gas turbines often require multiple proximity channels distributed around bearings and thrust positions. The 4.5-meter cable length gives engineers useful routing distance between the sensing point and monitoring electronics.
Compressor Monitoring
Compressors operate in environments where oil, process fluids, and mechanical vibration can create challenging cable-routing conditions. The FluidLoc construction provides an attractive option when additional fluid protection is desirable.
Pump and Motor Applications
The cable can be incorporated into monitoring systems for industrial pumps, motors, fans, and other rotating assets where the proximity probe must be separated from the Proximitor location.
Generator Condition Monitoring
Large generators may use proximity probes around bearing housings and shaft positions. A 4.5-meter extension can provide practical routing flexibility while retaining the defined electrical characteristics of the 3300 XL system.
Oil and Process Environments
Fluid exposure is one of the key reasons to consider a FluidLoc configuration. The cable construction is designed to provide additional resistance to fluid migration compared with a conventional cable arrangement.
Hazardous-Area Installations
The -05 multiple-approval configuration is associated with CSA, ATEX, and IECEx approvals, making the cable suitable for applications where the relevant certification is required and the complete installation meets the applicable hazardous-area requirements.
Replacement and Retrofit Projects
For an existing 3300 XL installation using a FluidLoc cable with connector protection, the exact 330130-045-12-05 configuration can simplify replacement work while preserving the original cable architecture.
Advantages
FluidLoc Protection
The defining feature of this model is its FluidLoc cable construction. It is designed for installations where fluid migration and environmental exposure are important considerations, providing an additional layer of protection beyond a conventional standard cable.
Integrated Connector Protection
The -12 configuration includes connector protectors, helping protect the connection area from mechanical contact and environmental exposure. The connector protector is identified as a fluorosilicone component in the 3300 XL documentation.
4.5-Meter Reach
A 4.5 m / 14.8 ft cable length offers a useful installation range for many rotating-machinery layouts. It allows the probe to remain near the measurement point while the Proximitor can be positioned at a more accessible location.
75 Ω Triaxial Design
The 75 Ω triaxial construction is part of the intended 3300 XL proximity-transducer architecture. It provides a controlled electrical path between the probe and signal-conditioning electronics.
Shielded Signal Path
The triaxial construction helps maintain signal integrity and reduce susceptibility to unwanted electrical interference, an important consideration around motors, generators, variable-frequency drives, and other industrial electrical equipment.
Multiple Agency Approvals
The 05 approval option provides multiple agency approvals, including CSA, ATEX, and IECEx configurations. This expands the range of installations for which the cable can be specified when the complete system satisfies the applicable requirements.
Compact FluidLoc Profile
Although designed for additional environmental protection, the FluidLoc cable remains relatively compact. Its approximately 3.94 mm maximum basic cable diameter allows practical routing through many constrained machinery areas.
Designed for System Matching
The 330130 cable is not an arbitrary extension cable. Its electrical length is intended to work as part of the complete 3300 XL probe-extension-Proximitor system. This helps maintain the specified electrical performance when the correct components are selected.
Strong Choice for Demanding Installations
For plants where oil, process fluids, moisture, or hazardous-area requirements influence cable selection, the 330130-045-12-05 provides a more specialized configuration than a basic standard extension cable.
Technical FAQs
1. What is the Bently Nevada 330130-045-12-05?
The 330130-045-12-05 is a 3300 XL Standard Extension Cable with a 4.5-meter length, FluidLoc cable construction, connector protectors, and a multiple-approval configuration.
2. How long is the 330130-045-12-05?
The cable length is 4.5 meters, equivalent to approximately 14.8 feet.
3. What does the “12” in the part number mean?
The 12 identifies a FluidLoc cable with connector protectors. This is different from configuration 03, which specifies an armored cable with connector protectors.
4. What does the final “05” specify?
The 05 identifies the multiple-approval option, associated with CSA, ATEX, and IECEx approvals for the applicable configuration.
5. What type of cable is used?
The 330130 family uses a 75 Ω triaxial cable. For the FluidLoc version, published specifications identify approximately 3.94 mm maximum cable outside diameter.
6. What is the minimum bend radius?
The minimum bend radius is 25.4 mm (1.0 inch). Cable routing should avoid sharper bends, particularly near connector transitions.
7. What are the dimensions and weight?
The cable is 4.5 m long. The FluidLoc cable has a maximum basic outside diameter of approximately 3.94 mm. Published cable-family specifications indicate approximately 34–37 g/m, giving an estimated cable-only mass of roughly 0.15–0.17 kg for 4.5 m, excluding connectors, protectors, and packaging.
8. Why is FluidLoc different from an armored cable?
The two configurations address different installation priorities. Armored cable emphasizes mechanical protection, while FluidLoc is designed to provide enhanced resistance to fluid migration. Configuration 12 combines FluidLoc construction with connector protectors.
9. Does the cable length need to match the probe length?
The physical length does not need to be identical to the probe length. Instead, the electrical length of the probe plus the electrical length of the extension cable must correspond to the required Proximitor Sensor total electrical length. This is a critical consideration when replacing components.
10. Can the 330130-045-12-05 replace a 330130-045-03-05?
Not automatically. Both are 4.5-meter cables with connector protection, but -12 is FluidLoc with connector protectors, whereas -03 is armored cable with connector protectors. Their environmental and mechanical characteristics differ, so the replacement should match the original system requirements rather than relying on cable length alone.
