Bently Nevada 330730-080-12-00 Extension Cable — Complete Product Guide
1. Product Overview
The Bently Nevada 330730-080-12-00 is an extension cable for the 3300 XL 11 mm Proximity Transducer System. It connects a compatible proximity probe to a Proximitor Sensor, providing the electrical path required for shaft vibration and displacement measurements in industrial machinery.
This model uses an 8.0 m cable with the FluidLoc cable option and connector protectors. The connector protectors help protect the connection area during installation and handling, while the FluidLoc construction is designed to limit the migration of fluids through the cable interior.
The cable is a passive component rather than an independent sensor. Its job is to maintain the specified electrical connection between the probe and Proximitor Sensor so that the complete measurement system can operate as designed.
The final suffix 00 identifies the option for which no additional agency approval is specified. Where a project requires particular hazardous-area or regulatory approvals, the exact equipment configuration and documentation must be checked before installation.

4. Product Introduction
The Bently Nevada 330730-080-12-00 extension cable is a connecting component for industrial proximity measurement systems. It is designed to carry the electrical signal between a compatible 3300 XL 11 mm proximity probe and the associated Proximitor Sensor.
In a typical installation, the proximity probe is mounted near a conductive shaft. When the distance between the probe tip and the shaft changes, the probe’s electrical response changes accordingly. The Proximitor Sensor conditions this response and provides a signal that compatible machinery monitoring equipment can use to evaluate shaft vibration or relative displacement.
The extension cable is an essential part of this measurement loop. Its electrical characteristics, physical length, and connection quality affect the behavior of the overall system. Selecting the correct cable is therefore important when commissioning new equipment or replacing a damaged component.
The 8.0 m cable length offers flexibility when the probe and signal-conditioning equipment are installed some distance apart. The FluidLoc construction is intended to limit the migration of oil or other liquids through the cable interior, while the connector protectors help protect the connection area from accidental contact and handling damage.
This model is best understood as a precision connection component for a matched measurement system, rather than as a general-purpose industrial cable.
5. Product Applications
5.1 Steam turbine monitoring
Steam turbines operate under demanding mechanical conditions, making shaft vibration and displacement monitoring important parts of machinery maintenance.
The 330730-080-12-00 can connect a compatible proximity probe to its Proximitor Sensor in a suitable turbine monitoring arrangement. Stable electrical connections help monitoring equipment receive consistent measurement signals for trend analysis and fault investigation.
5.2 Gas turbines and generators
Gas turbines and generators may require continuous monitoring of shaft movement, particularly in applications where unexpected mechanical deterioration could result in expensive downtime.
The 8.0 m cable length can accommodate installations where the probe and Proximitor Sensor are separated by a significant distance. The cable should be routed within its specified temperature and environmental limits.
5.3 Centrifugal compressors
Centrifugal compressors commonly use shaft proximity measurements to help identify changes in rotor behavior and mechanical condition.
The extension cable carries the probe signal to the Proximitor Sensor. A correctly matched cable helps preserve the electrical characteristics of the measurement loop, while damaged connectors or incorrect replacement cables can contribute to unstable or misleading readings.
5.4 Industrial pumps
Large pumps may incorporate proximity sensors when their design and monitoring requirements call for shaft displacement measurement.
The FluidLoc cable option can be useful in machinery areas where oil or other fluids are present. However, the cable’s suitability for a particular chemical exposure or installation environment must be verified against the applicable material specification.
5.5 Industrial rotating equipment
The cable may be used in other suitable rotating machinery installations that employ the compatible 3300 XL 11 mm proximity transducer system.
Its purpose is to maintain the connection between the sensing and signal-conditioning components. The resulting measurements can support condition monitoring, maintenance planning, and investigation of abnormal machine behavior.
6. Product Advantages
6.1 FluidLoc cable construction
The FluidLoc design is intended to restrict fluid migration through the cable interior. This can be useful in machinery installations where lubricating oil or other liquids may come into contact with the cable.
It does not eliminate the need for correct installation, appropriate sealing at external interfaces, and regular inspection.
6.2 Connector protection
The option 12 configuration includes connector protectors. These help protect the connection area during handling, installation, and maintenance.
Connector protection is particularly useful in installations where technicians need to route cables through equipment spaces with limited clearance. The available space should still be checked before installation.
6.3 Defined electrical characteristics
The cable uses a 75 Ω triaxial design with FEP insulation and a specified capacitance. These characteristics are intended to match the requirements of the compatible proximity measurement system.
Using the correct cable configuration helps avoid problems that may arise from an unsuitable impedance, capacitance, or cable length.
6.4 Practical 8.0 m length
The 8.0 m length provides flexibility in locating the probe and Proximitor Sensor within the permitted system arrangement.
Selecting the appropriate cable length can also help keep cable routing organized and avoid unapproved splices or modifications.
6.5 Straightforward replacement
A pre-terminated cable assembly can simplify replacement work because it reduces the need for field termination.
Before fitting a replacement, technicians should verify the complete model number, connector condition, cable length, and compatibility with the installed probe and Proximitor Sensor.
6.6 Supports continuous condition monitoring
When used correctly in a complete measurement channel, the cable supports the transmission of data used for shaft vibration and displacement monitoring.
This can contribute to maintenance planning and machinery diagnostics, although monitoring performance depends on the entire system, its configuration, and the interpretation of collected data.
6.7 Established product family
The 3300 XL 11 mm system uses defined components intended to work together. Choosing a cable from the correct family makes it easier to check compatibility with the installed probe and Proximitor Sensor.
The full ordering code remains important because different suffixes can indicate differences in cable construction, connector protection, or approval options.
