The 330130-030-00-00 is a 3.0-meter, unarmored 3300 XL series extension cable configured to transmit voltage signals between the probe and Proximitor sensor. It enables highly accurate static position and dynamic vibration measurements on fluid-film bearing machines, supporting critical applications such as speed and Keyphasor references.
High-temperature and highly chemical-resistant outer insulation jacket
Thin-diameter, unarmored, and highly flexible cable configuration
The mechanical architecture of the 330130-030-00-00 utilizes a flexible coaxial layout wrapped in a heavy-duty, high-temperature fluoropolymer insulation jacket. Both ends of the cable are factory-terminated with proprietary gold-plated ClickLoc coaxial connectors, which establish a secure physical link to the proximity probe and the Proximitor sensor. These specialized connectors feature a mechanical locking configuration that requires a specific tactile twist to engage, preventing the physical interface from loosening under the continuous structural vibrations of the bearing housing. Because this model is configured without stainless steel interlocking armor, the raw cable diameter remains thin and highly flexible, allowing it to be easily threaded through narrow conduit networks or complex machine casings.
From an electrical infrastructure perspective, this extension cable operates as a calibrated capacitance node within a strictly tuned radio-frequency oscillator loop. The center conductor exhibits a precise nominal direct current (DC) resistance of 0.222 Ω/m, while the outer coaxial shield layout maintains a resistance of 0.066 Ω/m to provide continuous noise immunity against electromagnetic interference. To preserve the micro-inch measurement linearity of the overall 3300 XL 8mm system, the cable capacitance is tightly governed at a typical rating of 69.9 pF/m. This unarmored 3.0-meter configuration must be combined exclusively with specific probe cable lengths to ensure the total system length strictly matches the 5-meter or 9-meter electrical tuning criteria mandated by the proximity sensor.

Oil & Gas
Used for monitoring shaft vibration of compressors and pumps in long-distance natural gas pipeline stations. Typical machinery includes centrifugal compressors and gas turbines.
Petrochemical & Refining
Measures shaft axial displacement of critical un-spared machine trains in hydrocracking and catalytic cracking units to prevent catastrophic impeller-to-casing contact.
Thermal Power Generation
Monitors shaft vibration and eccentricity of large steam turbine-generator sets in coal-fired or gas-fired power plants to ensure grid synchronization safety.
Hydroelectric Power Generation
Measures radial runout and shaft swing (runout) of hydro-turbine generator units, focusing on critical guide bearings.
Nuclear Power Generation
Provides highly reliable vibration condition monitoring for main feed water pumps and turbines in the conventional island of nuclear power plants.
Steel & Metallurgy
Monitors bearing vibration and shaft speed of blast furnace blowers and massive drive systems in rolling mills.
When using this extension cable, you must strictly maintain a minimum physical bend radius of over 25.4 mm during routing to prevent internal coaxial damage, ensure the ClickLoc connectors are twisted and locked completely into place with proper physical sealing using connector boots or silicone tape against oil ingress, route the entire unarmored cable body inside a protective external conduit when crossing high-friction or fluid-soaked areas, and strictly pair its 3.0-meter capacitance specification with designated probes to fulfill the total system length and impedance matching criteria.
The 330130-030-00-00 designates a 3300 XL 8mm Proximity Transducer System Standard Extension Cable. It has a physical length of 3.0 meters (9.8 feet) without a connector protector and requires no specific agency approvals. It is equipped with corrosion-resistant, gold-plated ClickLoc connectors on both ends to ensure seamless click-lock mating between the 8mm proximity probe and the Proximitor sensor.
What is the Bently Nevada 330130-030-00-00 hardware?
It is an industrial-grade 3300 XL series 8mm eddy current proximity transducer standard extension cable manufactured by Bently Nevada, serving as a dedicated signal transmission medium for machinery shaft vibration and position monitoring systems.
How do you use a cable product like the 330130-030-00-00?
On an industrial site, one end must be connected to the 8mm proximity probe installed on the bearing housing via its built-in coaxial connector, and the other end routed through cable trays into the Proximitor sensor input to completely transmit the high-frequency eddy current analog signals.
What physical interface does the 330130-030-00-00 cable utilize?
Both ends of this cable are equipped with proprietary, corrosion-resistant, gold-plated ClickLoc coaxial connectors to ensure loose-proof contact and low contact resistance during coupling.
How do you ensure mechanical safety when installing and routing the 330130-030-00-00 cable on-site?
Wiring must strictly comply with its officially specified minimum bend radius of 25.4 mm (1.0 in) without sharp kinks, and the cable must be secured inside non-vibrating, rigid trays to prevent electrical noise introduced by physical whipping.
What specific industrial rotating machinery is the 330130-030-00-00 typically used to monitor?
It is widely used in the power and petrochemical industries for condition monitoring of fluid-film bearings on steam turbines, gas turbines, large centrifugal compressors, high-pressure water pumps, and industrial fans.
