Introduction
The Bently Nevada 330130-040-00-TW is a 3300 XL Standard Extension Cable intended for compatible 3300 XL 8 mm proximity transducer systems. It provides the signal connection between a compatible proximity probe and Proximitor Sensor, forming an essential part of the measurement chain used for shaft vibration and position monitoring.
This configuration uses a 4.0 meter (13.1 ft) standard extension cable. The 040 code identifies the cable length, while 00 specifies the standard cable configuration. The TW suffix identifies the Taiwan-specific approval option, making this version appropriate for projects where the corresponding regional approval configuration is required.
The 3300 XL extension cable uses a 75 Ω triaxial, FEP-insulated construction with a typical capacitance of 69.9 pF/m (21.3 pF/ft). The nominal cable weight is approximately 34 g/m, giving the 4-meter version an estimated cable-only weight of around 0.136 kg.
For machinery-monitoring installations, the value of a correctly specified extension cable goes beyond physical reach. Cable length and electrical characteristics form part of the overall probe-to-Proximitor system configuration. The 330130-040-00-TW therefore offers a practical replacement and installation solution when a 4-meter standard cable with the TW approval configuration is required.

Applications
Turbine Vibration Monitoring
The 330130-040-00-TW can be incorporated into turbine monitoring arrangements where proximity probes are used to measure shaft movement and vibration. Its 4-meter length offers practical routing flexibility between the sensing point and Proximitor Sensor.
Compressor Condition Monitoring
Compressor trains often position proximity probes close to bearings while monitoring electronics are located in a more accessible area. The extension cable bridges this distance while maintaining the intended 3300 XL signal path.
Generator Monitoring
For large generators, proximity measurements can provide valuable information about rotor movement and shaft behavior. A 4-meter extension can accommodate installations where the Proximitor Sensor is positioned some distance from the probe.
Pump and Motor Applications
Industrial pumps and motors can use proximity-based monitoring as part of machinery protection and predictive maintenance programs. The standard cable configuration is well suited to conventional installations without specialized cable armor.
Fluid-Film Bearing Machines
The 3300 XL 8 mm proximity transducer system is designed for applications including fluid-film bearing machinery. The extension cable becomes part of the complete electrical circuit used for dynamic vibration and static shaft-position measurements.
Speed and Reference Monitoring
Compatible 3300 XL proximity systems can also support speed and Keyphasor-related applications when the complete system is correctly configured. The extension cable provides the necessary physical signal connection within that arrangement.
Taiwan-Based Industrial Projects
The TW configuration is intended for applications where the corresponding Taiwan-specific approval option is required. This makes it particularly useful for procurement and replacement projects in which regional certification is part of the equipment specification.
Maintenance and Retrofit Work
The 330130-040-00-TW is a convenient replacement candidate when an existing 3300 XL installation calls for a 4-meter standard extension cable with the TW approval configuration rather than a generic cable alternative.
Advantages
4 Meter Working Length
The 4.0-meter length gives installers useful freedom when routing between the proximity probe and Proximitor Sensor. It is long enough for many practical machinery layouts while remaining compact enough for straightforward cable management.
Taiwan-Specific Configuration
The TW suffix distinguishes this version from the standard -00-00 configuration and other regional variants. It provides a clearly defined approval option for projects requiring the Taiwan configuration.
Standard Cable Construction
The 00 cable option provides a conventional extension cable without the additional connector-protector configuration found on other 3300 XL variants.
75 Ω Triaxial Design
The 75 Ω triaxial construction is designed around the electrical requirements of the 3300 XL proximity measurement system, supporting stable signal transmission between the field sensor and Proximitor electronics.
FEP Insulation
FEP insulation provides a robust insulating material for industrial instrumentation cabling and supports dependable operation across the temperature range specified for the standard cable construction.
Defined Electrical Characteristics
The typical 69.9 pF/m capacitance is an important parameter when integrating the extension cable with a compatible probe and Proximitor Sensor.
Lightweight Installation
At approximately 34 g/m, the cable is easy to handle during routing and maintenance. The complete 4-meter cable weighs only about 0.136 kg before packaging.
Suitable for Critical Machinery
The cable can support monitoring systems installed on turbines, compressors, generators, pumps, motors, and other rotating equipment where dependable sensor connections are essential.
Easy Like-for-Like Replacement
For facilities already using the 3300 XL platform, the clearly defined length and approval configuration make the 330130-040-00-TW a practical option for restoring an existing monitoring circuit.
System-Oriented Selection
Because the extension cable forms part of the complete transducer system, selecting the correct length and configuration can help maintain the intended electrical characteristics rather than treating the cable as a simple passive replacement component.
Technical FAQs
1. What is the Bently Nevada 330130-040-00-TW?
It is a 3300 XL Standard Extension Cable designed to connect a compatible 3300 XL proximity probe with its Proximitor Sensor.
2. How long is the 330130-040-00-TW?

3. What does the first “00” indicate?
The first 00 identifies the standard cable configuration.
4. What does “TW” indicate?
The TW suffix identifies the Taiwan-specific approval configuration. The exact approval marking and applicability should be checked against the project documentation and the actual product nameplate before installation.
5. What is the cable capacitance?
The typical extension-cable capacitance is 69.9 pF/m (21.3 pF/ft).
6. What type of cable construction is used?
The standard extension cable uses a 75 Ω triaxial construction with FEP insulation.
7. What is the approximate weight?
The nominal cable weight is approximately 34 g/m, giving an estimated weight of about 0.136 kg for a 4-meter cable.
8. What machinery can use this extension cable?
Compatible applications include turbines, compressors, generators, pumps, motors, and other rotating machinery using a suitable 3300 XL proximity transducer arrangement.
9. Can the 330130-040-00-TW replace every 4-meter 330130 cable?
Not necessarily. The cable length alone does not determine compatibility. The cable configuration, approval option, probe, Proximitor Sensor, and total electrical system length should all be checked before selecting a replacement.
10. Why is total system length important?
The extension cable works as part of the complete probe-to-Proximitor electrical system. The probe length and extension-cable length must correspond to the total system length supported by the selected Proximitor Sensor. This is why a physically suitable cable is not automatically an electrically suitable replacement.
