Introduction
The Bently Nevada 330130-035-00-00 is a 3300 XL Standard Extension Cable designed to extend the connection between a compatible proximity probe and Proximitor Sensor within the 3300 XL 8 mm Proximity Transducer System.
With a 3.5 meter (11.5 ft) cable length, this configuration provides additional installation reach while retaining the standard cable design. The -00 connector and cable option identifies the standard cable configuration, while the final -00 agency option indicates that additional agency approvals are not required for this version.
The cable is designed around the electrical characteristics of the 3300 XL proximity system, including a typical capacitance of 69.9 pF/m (21.3 pF/ft). Its 3.5-meter length is a practical choice for machinery-monitoring layouts that require more routing distance than a 3.0-meter cable but do not need a substantially longer extension.
For maintenance teams, system integrators, and industrial reliability engineers, the 330130-035-00-00 offers a straightforward way to maintain the intended signal path between the sensing probe and monitoring electronics. It is particularly useful in established 3300 XL installations where matching the original cable configuration is important.

Applications
Turbine Vibration Monitoring
The 330130-035-00-00 can be incorporated into 3300 XL proximity monitoring arrangements used on steam and gas turbines. It provides the required signal connection between field-mounted proximity probes and their associated Proximitor Sensors.
Compressor Monitoring
Critical compressor trains often require carefully positioned proximity probes around bearings and shafts. The 3.5-meter extension provides additional routing flexibility while maintaining the standard cable configuration.
Generator Applications
Generators and other large rotating electrical machines can use proximity measurements to observe shaft movement and vibration. This extension cable can help connect field sensors to monitoring electronics positioned at a convenient location.
Pump and Motor Systems
Industrial pumps and motors can benefit from continuous shaft monitoring where vibration and position measurements are part of a predictive maintenance or machinery protection strategy.
Fluid-Film Bearing Machinery
The 3300 XL 8 mm Proximity Transducer System is designed for applications involving fluid-film bearing machinery. The extension cable forms part of the complete electrical measurement path used by these systems.
Industrial Machinery Protection
The cable can support proximity-based machinery protection arrangements where accurate transmission of the sensor signal to the Proximitor Sensor is essential for dependable monitoring.
Replacement and Retrofit Projects
The 330130-035-00-00 is a useful replacement option when an existing 3300 XL installation requires a 3.5-meter standard extension cable without additional agency approvals.
Advantages
Practical 3.5 Meter Reach
The 3.5-meter length offers a useful middle ground between shorter and longer cable configurations. It provides additional routing freedom without unnecessarily increasing cable length.
Standard Cable Configuration
The -00 cable option keeps the configuration straightforward, making it suitable for installations where an armored cable or connector-protector arrangement is not required.
Designed for 3300 XL Systems
The cable is purpose-configured for the 3300 XL proximity transducer architecture, supporting the connection between compatible probes and Proximitor Sensors.
Consistent Electrical Performance
With a typical capacitance of 69.9 pF/m, the cable maintains the electrical characteristics expected within the 3300 XL proximity measurement system.
Lightweight and Easy to Route
At approximately 34 g/m, the cable is relatively lightweight, which helps simplify installation, routing, securing, and replacement work.
FEP-Insulated Triaxial Construction
The 75 Ω triaxial cable uses FEP insulation and is designed for the signal-transmission requirements of the 3300 XL proximity system.
Maintenance-Friendly Replacement
A matching extension cable can help maintenance teams restore an existing monitoring circuit without changing the overall probe and Proximitor arrangement.
Flexible Installation
The 3.5-meter length provides enough additional distance for many machinery layouts, allowing monitoring equipment and field sensors to be positioned according to practical installation requirements.
Supports Critical Asset Monitoring
By maintaining the electrical connection between the proximity probe and Proximitor Sensor, the cable contributes to monitoring systems used on high-value rotating machinery where reliable instrumentation is essential.
Technical FAQs

It is a 3300 XL Standard Extension Cable used to connect a compatible proximity probe with a Proximitor Sensor in the 3300 XL 8 mm Proximity Transducer System.
2. What is the cable length?
The 035 length code specifies a cable length of 3.5 meters (11.5 feet).
3. What does the first “00” indicate?
The first 00 identifies the standard cable configuration rather than an armored or connector-protector option.
4. What does the final “00” indicate?
The final 00 identifies the agency approval option as not required.
5. What type of cable is used?
The 3300 XL standard 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 3.5-meter cable weigh?
The nominal cable weight is approximately 34 g/m, resulting in an estimated cable-only weight of approximately 0.119 kg for the 3.5-meter configuration.
8. What equipment is this cable designed to connect?
It is intended for use within compatible 3300 XL 8 mm Proximity Transducer Systems, providing the connection between a proximity probe and its associated Proximitor Sensor.
