The 330130-075-11-05 is the complete selection order number for the 3300 XL series 8mm standard extension cable manufactured by Bentley Nevada, USA. Its main function is to transmit the micron-level high-frequency vibration signals captured by the eddy current proximity probe to the preamplifier without loss, thereby achieving precise monitoring of shaft vibration and displacement in large rotating machinery.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components. Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable with other non XL 3300 series 5 mm and 8 mm transducer system components. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

Petroleum Refining Industry
Used in high-speed centrifugal hydro-treating feed pump trains, utilizing FluidLoc technology to prevent high-pressure lubricating oil inside the pump casing from leaking along the cable core to the external junction box.
Thermal Power
Applied outside the fluid-film bearings of large steam turbine-generator sets, where the 7.5-meter length facilitates signal routing across machinery platforms to transmit shaft vibration and displacement signals.
Petrochemical Industry
In million-ton ethylene cracked gas compressor trains, its stainless steel armor conduit protects the signal lines from erosion by highly corrosive gases and damage from acid or alkali drips on chemical sites.
Hydropower Industry
Installed outside the water guide and lower guide bearings of large vertical hydro-turbine generator sets, where the stainless steel armor structure perfectly resists physical wear on cables in damp, moisture-rich environments.
Nuclear Power
Installed around the main reactor coolant pumps (RCPs) in nuclear reactor buildings, utilizing its highly reliable triaxial cable shielding layer to suppress complex electromagnetic interference, ensuring the accuracy of shaft vibration monitoring data.
When using the 330130-075-11-05 extension cable, follow four rules. First, avoid sharp bends by keeping the bending radius above 25.4 mm to protect the armored internal coaxial line. Second, match length strictly by pairing the 7.5m cable only with a 1.5m probe and a 9m Proximitor system without cutting. Third, protect connectors with a dedicated sleeve after mating to prevent moisture and oil contamination. Fourth, keep armor floating as the stainless steel outer layer is for physical protection only and must not be grounded to prevent noise.
The 330130-075-11-05 is the complete selection part number for a 3300 XL Standard Extension Cable manufactured by Bently Nevada.
How to ensure that the connectors of 330130-075-11-05 do not get damp due to the lack of a protector during wiring?
After completing on-site mating, heat-shrink tubing or an independently purchased genuine Bently Nevada external connector protector kit should be used to seal the finger-tightened coaxial coupling.
Does the stainless steel armor layer of 330130-075-11-05 need to be grounded?
No, the stainless steel armor is for mechanical protection; the armor layer should remain floating to prevent ground loop noise from interfering with the signal.
What length specification of probe should 330130-075-11-05 be connected to?
Since its length is 7.5 meters, it must and can only be connected to a proximity probe with a 1.5-meter integrated cable to assemble a standard 9-meter transducer system.
What special technology is inside 330130-075-11-05 to prevent fluid leakage from the machine?
It utilizes FluidLoc technology, which effectively prevents lubricating oil inside the machine casing from leaking out along the cable core capillaries.
