Introduction
The Bently Nevada 330130-040-01 is a 3300 XL Standard Extension Cable configured with an armored cable construction for installations where additional mechanical protection is preferred. It is designed for use within compatible 3300 XL proximity transducer systems, providing the connection between a proximity probe and its associated Proximitor Sensor.
The 040 designation identifies a 4.0 meter (13.1 ft) cable length, while 01 specifies the armored cable option. This makes the model different from the standard 330130-040-00 configuration, particularly where the cable route may be exposed to greater mechanical handling, abrasion, or installation-related stress.
The 3300 XL extension-cable family is engineered as part of a complete proximity measurement system. The extension cable length and probe length must be selected so that their combined length matches the total system length supported by the Proximitor Sensor. This is important for maintaining the intended electrical performance of the complete transducer arrangement.
For maintenance teams and machinery-monitoring integrators, the 330130-040-01 offers a practical combination of 4-meter reach and enhanced physical protection. It is a particularly attractive option when a conventional standard cable is not sufficient for the installation environment.

Applications
Turbine Monitoring
The 330130-040-01 can be used as part of a proximity monitoring arrangement on steam and gas turbines. The armored construction is useful where cable routing requires additional protection against physical contact or installation-related damage.
Compressor Trains
Compressors frequently operate in equipment areas where instrumentation cables must be carefully routed around machinery structures. A 4-meter armored extension provides useful installation flexibility while adding mechanical protection to the cable assembly.
Generator Applications
Generator monitoring systems may use proximity probes at several shaft and bearing locations. The 330130-040-01 can provide the required extension between the probe and Proximitor Sensor where a more robust cable configuration is desirable.
Pump and Motor Monitoring
Industrial pumps and motors can benefit from continuous vibration and shaft-position monitoring. The armored extension cable provides a durable connection option for installations where cables may be exposed to routine maintenance activity.
Fluid-Film Bearing Systems
The 3300 XL 8 mm proximity system is commonly applied to machinery using fluid-film bearings. The extension cable forms part of the electrical measurement circuit between the proximity probe and Proximitor Sensor.
Machinery Protection
For critical rotating equipment, reliable sensor connections are essential to the overall monitoring system. The armored configuration can be advantageous when cable protection is an important part of the installation design.
Retrofit Installations
The 330130-040-01 is well suited to retrofit work where an existing 3300 XL system requires a 4-meter armored extension cable instead of a standard unarmored configuration.
Maintenance Replacement
When an existing armored extension cable has been damaged or needs replacement, matching the cable length and configuration can help restore the original monitoring arrangement without unnecessary changes to the rest of the transducer system.
Advantages
Armored Cable Protection
The defining characteristic of the 01 option is its armored construction. Compared with the standard cable option, this configuration provides additional physical protection for installations where mechanical durability is a greater concern.
Practical 4 Meter Reach
At 4.0 meters, the cable provides substantial routing flexibility between a field-mounted probe and the Proximitor Sensor while remaining manageable during installation.
Better Suited to Demanding Cable Routes
Armored construction can be particularly valuable in equipment areas where cables may pass close to structural components, maintenance access points, or other locations with increased risk of physical contact.
3300 XL System Compatibility
The cable is part of the established 3300 XL proximity transducer architecture and is intended to be used with compatible probes and Proximitor Sensors.
Defined Electrical Characteristics
The extension cable has a typical capacitance of 69.9 pF/m (21.3 pF/ft). Maintaining the appropriate total probe-plus-extension length is important for proper system operation.
Professional Replacement Choice
For an existing installation using an armored 3300 XL extension cable, selecting the corresponding 01 configuration can provide a cleaner like-for-like replacement than switching to a standard cable.
Lightweight Relative to Cable Length
Despite its armored configuration, the cable remains practical to handle during routing and maintenance. The nominal cable weight is approximately 34 g/m.
Supports Critical Machinery Monitoring
The cable provides the physical connection required for proximity measurement systems used on high-value rotating assets, helping maintain continuity between the field sensing point and monitoring electronics.
Flexible for Plant Maintenance
A 4-meter armored extension is useful for both new installations and maintenance work, particularly where cable protection requirements are more demanding than those of a conventional instrument-cable route.
Technical FAQs
1. What is the Bently Nevada 330130-040-01?
The 330130-040-01 is a 3300 XL Standard Extension Cable with the armored cable option. It is used within compatible 3300 XL proximity transducer systems.
2. What is the cable length?
The cable length is 4.0 meters (13.1 feet). The 040 portion of the model designation identifies the length option.
3. What does “01” mean?
The 01 cable option identifies the armored cable configuration.
4. How is it different from 330130-040-00?
The major difference is the cable construction. 330130-040-00 uses the standard cable option, while 330130-040-01 uses an armored cable configuration.
5. What is the typical capacitance?
The typical extension-cable capacitance is approximately 69.9 pF/m (21.3 pF/ft).
6. What is the approximate cable weight?
Using the nominal 34 g/m cable weight, a 4-meter cable has an estimated cable-only weight of approximately 0.136 kg. Product listings may show different weights depending on whether the figure refers to the cable itself, complete assembly, or packaged shipment.
7. What equipment does this cable connect?
It connects a compatible 3300 XL proximity probe to a Proximitor Sensor, forming part of the complete proximity transducer measurement system.
8. Where is an armored extension cable useful?
It is particularly useful in installations where the cable route may be exposed to mechanical contact, abrasion, maintenance activity, or other conditions where additional cable protection is desirable.
9. Can this cable be used with a 3300 XL 8 mm probe?
Yes, provided the probe, extension cable, and Proximitor Sensor are selected as a compatible system. The combined probe and extension length must match the required Proximitor Sensor total length.
10. What should be checked before ordering?
Confirm the 4.0-meter length, armored 01 configuration, connected probe length, Proximitor Sensor model, total electrical system length, and any required agency approval option. Matching the complete configuration is more important than simply matching the physical cable length.
