Introduction
The Bently Nevada 330130-040-00 is a 3300 XL Standard Extension Cable designed to provide a dependable electrical link between a compatible 3300 XL proximity probe and Proximitor Sensor. As a key component of the 3300 XL 8 mm Proximity Transducer System, the cable carries the measurement signal required for monitoring shaft vibration, position, speed, and related rotating-machine conditions.
This model uses a 4.0 meter (13.1 ft) standard cable configuration. The 040 designation identifies the cable length, while 00 specifies the standard cable option and the final 00 indicates that no additional agency approval is required.
The cable uses a 75 Ω triaxial construction with FEP insulation and has a typical capacitance of 69.9 pF/m (21.3 pF/ft). These electrical characteristics are important because the extension cable is part of the complete proximity transducer circuit and must be correctly matched with the probe and Proximitor Sensor.
For industrial maintenance teams, OEM system integrators, and machinery reliability professionals, the 330130-040-00 offers a practical 4-meter connection solution for established 3300 XL monitoring installations. Its standard configuration is well suited to applications where specialized armored construction, connector protection, or additional agency approvals are not required.

Applications
Rotating Machinery Vibration Monitoring
The 330130-040-00 forms part of the electrical measurement path used by a 3300 XL proximity transducer system. It connects the field-mounted sensing probe to the Proximitor Sensor, allowing the system to process shaft movement and vibration information.
Turbine Applications
Steam and gas turbines commonly require proximity measurements at critical shaft locations. The 4-meter extension length can provide convenient routing between turbine-mounted probes and the associated signal-conditioning equipment.
Compressor Trains
In compressor applications, accurate shaft measurements are important for machinery protection and condition monitoring. The cable provides the necessary connection for compatible 3300 XL probe configurations.
Generator Monitoring
Large generators may have monitoring points distributed around the rotor and bearing assemblies. A 4.0-meter extension can provide additional installation flexibility where the Proximitor Sensor is positioned away from the sensing location.
Pumps and Motors
Industrial pumps, motors, and motor-driven equipment can incorporate proximity transducers to monitor shaft movement and vibration. The standard extension cable provides a straightforward connection solution for these installations.
Fluid-Film Bearing Machinery
The 3300 XL 8 mm Proximity Transducer System is particularly suited to machinery using fluid-film bearings. The 330130-040-00 can form part of the complete probe, extension cable, and Proximitor arrangement used for static and dynamic measurements.
Speed and Keyphasor Applications
When used as part of a correctly configured 3300 XL system, proximity transducers can also support speed measurement and Keyphasor reference applications. The extension cable helps maintain the required signal path between the field sensor and associated electronics.
Maintenance and Retrofit Projects
The 330130-040-00 is a practical replacement option for existing 3300 XL installations where a 4.0-meter standard extension cable with no additional agency approval is required.
Advantages
Balanced 4 Meter Length
The 4.0-meter configuration offers a useful compromise between installation reach and cable management. It provides more routing freedom than shorter versions while avoiding unnecessary excess length in many equipment layouts.
Standard Configuration for Straightforward Installations
The standard -00 cable option is suitable for applications that do not require specialized armored construction or other enhanced cable configurations.
75 Ω Triaxial Construction
The 75 Ω triaxial design is configured for the electrical requirements of the 3300 XL proximity transducer system, helping maintain the intended signal characteristics throughout the measurement chain.
FEP Insulation
FEP insulation provides a durable and stable insulation system for industrial instrumentation applications, supporting reliable cable performance across demanding operating conditions.
Controlled Cable Capacitance
The typical 69.9 pF/m capacitance is an important characteristic of the 3300 XL extension cable. Correct cable selection helps maintain the electrical relationship between the probe, extension cable, and Proximitor Sensor.
Lightweight and Easy to Handle
With a nominal linear weight of approximately 34 g/m, the 4-meter cable is relatively lightweight, making installation, routing, securing, and replacement more manageable.
Compatible 3300 XL Architecture
The cable is designed for the established 3300 XL proximity transducer architecture, allowing compatible probes, extension cables, and Proximitor Sensors to function as an integrated measurement system.
Supports Multiple Monitoring Functions
A correctly configured 3300 XL system can support static shaft-position measurements, dynamic vibration monitoring, speed measurements, and Keyphasor reference applications.
Maintenance-Friendly Replacement
For plants already operating Bently Nevada 3300 XL equipment, replacing a damaged or aged extension cable with the corresponding 330130-040-00 configuration can help preserve the original system arrangement.
Professional Solution for Critical Equipment
Although physically simple, the extension cable plays an important role in the complete proximity measurement circuit. Choosing the correct length and configuration helps protect the consistency and reliability of the overall monitoring system.
Technical FAQs
1. What is the Bently Nevada 330130-040-00?
The 330130-040-00 is a 3300 XL Standard Extension Cable used to connect a compatible proximity probe with a Proximitor Sensor within a 3300 XL proximity transducer system.
2. What is the length of the 330130-040-00?
The cable is 4.0 meters (13.1 feet) long. The 040 portion of the model number identifies the 4.0-meter length option.
3. What does the first “00” mean?
The first 00 identifies the standard cable configuration.
4. What does the final “00” represent?
The final 00 indicates that an additional agency approval option is not required for this configuration.
5. What type of cable construction does it use?
The extension cable uses a 75 Ω triaxial construction with FEP insulation.
6. What is the typical capacitance?
The typical extension-cable capacitance is approximately 69.9 pF/m (21.3 pF/ft).
7. How much does the 4-meter cable weigh?
The nominal cable weight is approximately 34 g/m, resulting in an estimated cable-only weight of approximately 0.136 kg for 4.0 meters.
8. What equipment is the cable designed to connect?
It is designed for compatible 3300 XL 8 mm Proximity Transducer Systems, connecting the proximity probe with its associated Proximitor Sensor.
