Bently Nevada 330730-080-10-05 Extension Cable — Product Overview and Technical Specifications
1. Product Overview
The Bently Nevada 330730-080-10-05 is an extension cable in the 3300 XL 11 mm proximity transducer system. It is designed to connect a compatible proximity probe to its associated Proximitor Sensor, carrying the measurement signal through the monitoring circuit.
This cable is intended for industrial machinery condition monitoring, where reliable measurement of shaft vibration, relative shaft displacement, and other mechanical movement is important to equipment operation and maintenance.
The model code identifies an 8.0-metre cable, a FluidLoc cable construction, and a multiple-agency approval option. The cable forms part of a matched measurement system, so its electrical characteristics and total system length should be considered alongside the probe and Proximitor Sensor rather than selecting it by physical length alone.

Understanding the main electrical specifications
75 Ω triaxial construction
The cable’s electrical design is intended to work with the compatible proximity measurement circuit. Correct impedance and cable characteristics help preserve the measurement signal and reduce problems caused by unsuitable replacement wiring.
Typical capacitance of 69.9 pF/m
Cable capacitance affects the electrical characteristics of the complete probe-cable-Proximitor combination. A replacement cable should therefore be selected according to the system’s specified configuration rather than on length alone.
8.0 m cable length
The 080 code identifies the nominal 8.0 m cable length. The cable length must be considered together with the probe cable length and the Proximitor Sensor’s specified system length. An incorrect combination may produce measurement errors or prevent the system from operating within its intended range.
FluidLoc cable construction
The 10 option identifies the FluidLoc cable configuration. It is intended for industrial measurement applications where cable construction and environmental resistance matter. The exact resistance to particular oils, chemicals, mechanical loads, and environmental conditions should be checked against the applicable product documentation.
Multiple-agency approval option
The 05 suffix identifies a multiple-approval ordering option. Actual approvals and their scope should be confirmed on the delivered product and accompanying records before installation in a regulated or hazardous area.
4. Product Description
The Bently Nevada 330730-080-10-05 extension cable is a component of an industrial proximity measurement system used to monitor the mechanical condition of rotating machinery. It connects the compatible probe assembly to the associated Proximitor Sensor, providing the required signal path between the sensing point and the monitoring electronics.
In a typical installation, the probe is positioned near a conductive rotating shaft. As the distance between the probe tip and the shaft changes, the probe and Proximitor Sensor convert the resulting electrical response into a signal that can be used to determine shaft displacement or vibration.
The extension cable plays an important supporting role in this process. Although it does not directly measure shaft movement, the cable’s length, electrical characteristics, connector condition, and routing influence the performance of the complete measurement loop.
The 8.0 m configuration is useful where the physical distance between the probe installation and the associated signal-conditioning equipment calls for a longer cable assembly. The final choice should account for the actual equipment layout, cable routing, and total system-length requirements.
The FluidLoc construction and pre-terminated connector arrangement are intended to simplify installation compared with assembling a cable from separate field components. Correct part-number matching remains important, especially where the equipment is used for continuous monitoring or machinery protection.
5. Product Applications
5.1 Steam turbines
Steam turbines rely on accurate machinery measurements to help operators identify abnormal shaft movement, changing vibration levels, and potential mechanical deterioration.
When installed in a compatible proximity measurement loop, the 330730-080-10-05 carries the signal from the probe to the Proximitor Sensor. The resulting measurement can then be passed to the appropriate monitoring equipment.
The cable itself does not provide turbine protection, but it supports the signal path used by the larger monitoring system.
5.2 Gas turbines
Gas turbines operate under demanding mechanical and thermal conditions. Reliable monitoring instrumentation is important for identifying developing problems and supporting maintenance planning.
The extension cable can be used in a compatible shaft proximity measurement arrangement, provided its cable routing, environmental exposure, and system compatibility meet the installation requirements.
5.3 Centrifugal compressors
Centrifugal compressors are commonly monitored for shaft vibration and relative shaft displacement. Changes in these measurements can help maintenance teams investigate rotor instability, bearing-related problems, alignment issues, or other developing mechanical conditions.
The extension cable connects the measurement components and helps preserve the intended electrical characteristics of the proximity system.
5.4 Pumps and other rotating machinery
Industrial pumps, motors, and other rotating equipment may use proximity measurements where the machine design and monitoring requirements call for them.
The cable can be appropriate for such installations when the probe, Proximitor Sensor, cable length, and monitoring equipment are all compatible. Not every pump or motor uses an eddy-current proximity system, so the actual instrumentation design must be checked before selecting this component.
5.5 Industrial machinery monitoring systems
The cable may also be used in broader industrial condition-monitoring installations that incorporate compatible proximity sensors and machinery monitoring hardware.
Typical objectives include continuous measurement, trend analysis, identification of abnormal operating conditions, and support for maintenance decisions. The quality of these functions depends on the complete measurement system, installation quality, and the monitoring equipment’s configuration.
6. Product Advantages
6.1 Supports reliable signal transmission
The extension cable is designed for use in a defined proximity measurement system. Maintaining the specified cable characteristics helps the connected probe and Proximitor Sensor operate as intended.
Using the correct cable type is particularly important when replacing a cable in an existing measurement channel, because an electrically different cable may affect system performance.
6.2 Provides a practical 8.0 m connection length
The 8.0 m length provides additional routing flexibility when the probe and associated electronics are not close together.
This can help accommodate machinery layouts, equipment cabinets, and cable tray arrangements while avoiding unnecessary intermediate connections.
6.3 FluidLoc cable option
The FluidLoc configuration provides a defined cable construction for industrial use. This may be beneficial in installations where the cable must be routed through an environment that requires suitable jacket and material characteristics.
Environmental suitability should still be assessed against the actual operating conditions, including temperature, chemical exposure, movement, and mechanical protection requirements.
6.4 Pre-terminated connection design
A factory-assembled cable can reduce the need for field termination and the associated risk of incorrect wiring or inconsistent assembly.
The installer should nevertheless inspect the connectors, verify the part number, and follow the specified connection and handling procedure.
6.5 Supports continuous machinery monitoring
When used in a correctly configured measurement loop, the cable supports the transmission of measurements that monitoring equipment can use for trend analysis and machinery diagnostics.
This is useful for facilities that need consistent data over extended operating periods. It does not guarantee fault detection on its own; the complete monitoring system must be configured, maintained, and interpreted correctly.
6.6 Multiple-agency approval option
The 05 configuration is intended for orders requiring multiple-agency approvals. This can be relevant to industrial projects with defined compliance requirements.
The precise certification status must be verified for the actual item supplied. The suffix alone should not replace the required inspection of markings and documentation.
6.7 Supports replacement and maintenance work
An exact replacement cable can simplify maintenance by preserving the intended cable length and configuration.
For replacement work, the original installed part number should be compared with the proposed cable, and the entire probe-cable-Proximitor combination should be checked before the machinery is returned to service.
