The 330130-080-11-05 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 shaft variation signal 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 8.0-meter length facilitates signal routing across broad machinery platforms to transmit shaft vibration and displacement signals.
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.
Iron & Steel Metallurgy
Outside the fluid-film bearings of blast furnace blowers in iron-making plants, leveraging its wide temperature tolerance (-35°C to +177°C) to withstand the effects of high-temperature radiant heat on metallurgical sites.
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 330130-080-11-05 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 8.0m cable only with a 1.0m 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 330130-080-11-05 is the complete selection part number for a 3300 XL Standard Extension Cable manufactured by Bently Nevada.
Can 330130-080-11-05 be used alone and independently?
No, it cannot. It must be paired with a 1.0-meter proximity probe and a 9.0-meter system Proximitor Sensor, all three are indispensable.
How to on-site test if the conductivity of 330130-080-11-05 cable is in good condition?
Use a multimeter to measure the DC resistance across the center conductor and shield, the standard center conductor resistance is typically around 0.222 ohms/meter.
Does the stainless steel armor layer of 330130-080-11-05 need to be grounded?
No, the stainless steel armor is for mechanical protection, the signal cable shield should be single-point grounded near the Proximitor end, and the armor should remain floating to prevent ground loop interference.
What special technology is inside 330130-080-11-05 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.
