The 330130-080-03-CN is an essential 8 mm proximity transducer probe component within the Bently Nevada 3300 XL series eddy current measurement infrastructure. As a part of this advanced instrumentation network, the complete system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface, allowing for seamless monitoring of both static position (displacement) and dynamic vibration values.

The primary industrial applications for this specific metric M10×1 threaded hardware are radial vibration and axial position measurements on high-speed fluid-film bearing machinery, as well as serving as a dedicated Keyphasor reference for accurate shaft rotational 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.

When using the 330130-080-03-CN, strictly maintain system length matching by pairing it only with 1.0m or 0.5m probes, and never cut the cable to avoid impedance failure. Observe minimum bend radius limits (min 31.8 mm for armored and 25.4 mm for unarmored) during routing to prevent core crushing.
Ensure connectors are sealed with insulation boots to prevent ground loops from casing contact, and avoid prolonged submersion in oil or water. Route the cable through metal conduits well away from power lines, motors, and VFDs to isolate electromagnetic interference.
The Bently Nevada 330130-080-03-CN is a dedicated 8.0-meter extension cable with stainless steel armor and explosion-proof certification, purpose-built for the 3300 XL 8mm proximity transducer system. It functions as a critical physical link to transmit high-frequency shaft vibration and thrust position signals from the probe to the Proximitor sensor without degradation. Featuring an oil-resistant, anti-corrosive fluoropolymer jacket and high-density electromagnetic shielding, the cable effectively eliminates high-frequency crosstalk and stray noise, ensuring robust physical-layer signal integrity for critical rotating machinery protection networks during long-term continuous operation.
330130-080-03-CN is a 3300 XL Standard Extension Cable.
What does the 330130-080-03-CN primarily measure?
It is used for non-contact, precision measurement of radial vibration, axial position (thrust), keyphasor (speed), and bearing clearance on rotating machinery (such as steam turbines, compressors, etc.).
What is the operating principle of the 330130-080-03-CN?
It operates on the eddy current principle.
How to install and use the 330130-080-03-CN?
Install it perpendicularly on the bearing housing using a dedicated bracket, adjust the physical gap between the probe tip and the shaft surface using a multimeter until the Proximitor outputs the mid-range linear voltage (typically -10V DC), then lock the retaining nuts.
What complementary hardware does the 330130-080-03-CN require to work?
It must be connected to an extension cable (to bring the total electrical length to 5 or 9 meters) and a 3300 XL Proximitor sensor unit.
