The 330130-040-00-05 is a Bently Nevada 3300 XL Standard Extension Cable used for linking 8mm proximity probes to Proximitor sensors. This model features a 4.0-meter cable length with heavy-duty stainless steel armor to deliver superior physical protection against mechanical wear and pulling in harsh industrial environments. Equipped with secure, moisture-resistant coaxial connectors and backed by standard multi-national industrial approvals, it guarantees highly accurate, low-loss, and reliable vibration signal transmission under severe conditions.

The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
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.

Thermal Power Plants
Used for axial displacement and radial vibration monitoring of steam turbine generators, where the 4.0-meter length perfectly extends to the protection box outside the bearing housing.
Petroleum Refining & Petrochemicals
Connecting probes installed on hydrocracking recycle hydrogen compressors, where its wide temperature range of -51°C to +177°C withstands severe temperature fluctuations in refineries.
Natural Gas Long-Distance Pipelines
Used on pipeline centrifugal compressors in unmanned gas transmission stations, leveraging its high reliability for long-term, maintenance-free bearing wear monitoring.
Nuclear Power Industry
Used for shaft vibration measurement of turbine-driven feedwater pumps, fully meeting the high-precision requirements of the API 670 standard.
Iron, Steel & Metallurgy Industry
Installed on large centrifugal blast furnace blowers to transmit high-frequency vibration signals while withstanding thermal radiation and industrial dusty environments around steel mills.
Large Hydroelectric Power
Deployed on the guide and thrust bearings of vertical hydro turbine generators, where the 4-meter cable runs through large-diameter bearing housings for wiring.
When operating this cable, first, it must be strictly paired with a 1.0-meter probe to maintain a 5.0-meter total system length for factory calibration accuracy.
Second, during routing, the bend radius must not be less than 25.4 mm, and any cutting or re-splicing is strictly prohibited to prevent impedance alteration and signal distortion.
Third, the connectors must be tightened to 0.565 N·m using a dedicated torque wrench and must be strictly sealed with silicone self-fusing tape or connector protectors to prevent the ingress of lube oil, moisture, or conductive dust.
The Bently Nevada 330130-040-00-05 is a 4.0-meter standard unarmored extension cable designed for the 3300 XL 8mm proximity transducer system. Featuring an FEP insulation layer, the cable supports an operating temperature range of -51°C to +177°C and carries CSA/ATEX/IECEx hazardous area approvals, ensuring accurate vibration signal transmission in rotating machinery.
It is a standard extension cable within the Bently Nevada 3300 XL 8mm proximity transducer system.
Where is 330130-040-00-05 primarily used?
It is used to connect a Proximitor Sensor and a proximity probe, working together to monitor bearing vibration and displacement in large rotating machinery such as steam turbines and compressors.
How to properly use a product like 330130-040-00-05?
Securely tighten both ends via specialized coaxial connectors to a 3300 XL 8mm probe and a 3300 XL Proximitor, ensuring compliant connection using a dedicated torque wrench.
Can 330130-040-00-05 be freely paired with a probe of any length?
No. Because proximity systems have strict capacitance requirements, this 4.0m extension cable must be paired with a 1.0-meter cable length probe to form a standard 5.0-meter total system length.
What material is used for the 330130-040-00-05 cable?
It utilizes a high-quality 75 Ω triaxial cable with fluoroethylene propylene (FEP) insulation.
