Introduction
The Bently Nevada 330130-030-00-00 is a 3300 XL Standard Extension Cable designed to connect a compatible proximity probe with its Proximitor Sensor in a machinery vibration and position monitoring system. As part of the 3300 XL 8 mm Proximity Transducer System, it provides the electrical connection required to transmit measurement signals from the probe to the associated monitoring electronics.
This configuration features a 3.0 meter (9.8 ft) cable length, standard cable construction, and no additional agency approval option. Its practical length makes it a versatile choice for installations where the proximity probe and Proximitor Sensor are positioned relatively close to one another while still requiring additional routing flexibility.
The 330130-030-00-00 is particularly useful in rotating machinery applications where reliable signal transmission is essential to continuous condition monitoring. It can be incorporated into monitoring arrangements for turbines, compressors, pumps, motors, generators, and other critical equipment.
For maintenance teams supporting an established 3300 XL installation, the cable provides a straightforward replacement option that helps preserve the intended probe-to-Proximitor connection without introducing unnecessary changes to the existing system architecture.

Applications
Proximity Probe Connections
The primary role of the 330130-030-00-00 is to provide the electrical connection between a compatible 3300 XL proximity probe and Proximitor Sensor. It forms an essential part of the complete measurement chain.
Turbine Monitoring
In turbine applications, the extension cable can carry proximity measurement signals from shaft-monitoring probes to the associated Proximitor equipment, supporting continuous vibration and position monitoring.
Compressor Systems
Critical compressors rely on accurate shaft-condition information. A correctly configured extension cable helps maintain the electrical connection between the sensing element and monitoring electronics.
Pump and Motor Monitoring
The cable can be used in monitoring arrangements for pumps and motors where proximity probes are installed to observe shaft movement, vibration, or position.
Generator Applications
Generators and other rotating electrical machines can incorporate 3300 XL proximity monitoring systems to track changes in shaft behavior. The extension cable provides the required connection between field-mounted probes and associated monitoring equipment.
Industrial Machinery Protection
The cable can contribute to machinery protection systems in which probe signals are continuously transmitted to monitoring equipment for condition assessment and alarm functions.
Replacement and Maintenance
For maintenance departments supporting existing 3300 XL installations, the 3.0 m standard extension cable provides a practical replacement option when the original cable has been damaged, aged, or otherwise requires replacement.
Advantages
Purpose-Built for the 3300 XL System
The 330130-030-00-00 is specifically configured as part of the 3300 XL proximity transducer system, making it a natural choice when maintaining a compatible Bently Nevada installation.
3 Meter Installation Length
The 3.0 meter length provides useful routing flexibility without adding unnecessary cable length to compact machinery-monitoring installations.
Reliable Signal Transmission
The 75 Ω triaxial cable construction is designed for transmission of proximity measurement signals between the probe and Proximitor Sensor while maintaining the electrical characteristics required by the monitoring system.
FEP Insulation
FEP insulation provides a durable cable construction suitable for industrial instrumentation applications and helps maintain stable electrical performance across the specified operating environment.
Lightweight Design
At approximately 34 g/m, the cable remains relatively lightweight and manageable during installation, routing, and maintenance.
Flexible Routing
The cable can be routed around machinery structures and monitoring panels while maintaining an appropriate bend radius. This gives maintenance teams greater freedom when arranging the probe-to-Proximitor connection.
Simple Replacement
The standard configuration makes the cable a practical replacement component for maintenance teams that need to restore an existing 3300 XL proximity measurement circuit.
Supports Continuous Monitoring
A dependable connection between the probe and Proximitor Sensor is essential for continuous vibration and shaft-position monitoring. This cable helps maintain the signal path on which the monitoring system depends.
