Bently Nevada 3300 XL Series Extension Cable 330130-080-10-05 8.0m Length

Brief Product Summary

This 8-meter Bently Nevada 330130-080-10-05 extension cable bridges the gap between proximity probes and monitoring electronics within a 3300 XL transducer system. It maintains electrical linearity and environmental resistance, ensuring that vibration and position data remain accurate across the entire signal path.

Technical Overview and Functional Description

The Bently Nevada 330130-080-10-05 functions as a vital intermediary in the 3300 XL 8mm Proximity Transducer System. By connecting the proximity probe to the Proximitor sensor, this 8-meter cable facilitates the transmission of high-frequency signals necessary for monitoring shaft vibration and axial position. Because this cable utilizes FluidLoc technology, it effectively prevents oil and other contaminants from leaking through the cable interior, thereby protecting sensitive electronic components in the signal chain.

Adherence to the API 670 standard ensures that this extension cable provides total interchangeability. Consequently, users can replace cables without the need for time-consuming bench calibration or matching components. While specifically designed for the XL series, the 330130-080-10-05 maintains backward compatibility with legacy 3300 series 5mm and 8mm systems. This flexibility allows facilities to upgrade their monitoring infrastructure incrementally while maintaining existing sensor installations.

Beyond simple signal transmission, the cable’s mechanical design focuses on durability in high-temperature and high-pressure environments typical of Turbine Supervisory Instrumentation (TSI). Its robust shielding minimizes electromagnetic interference, which preserves the integrity of the proportional voltage output. This reliability makes the 330130-080-10-05 an industry standard for monitoring fluid-film bearing machines, including steam turbines, centrifugal compressors, and large-scale pumps.

Key Technical Characteristics

• 8-Meter Length: Provides significant reach for complex machinery layouts while maintaining calibrated electrical impedance.
• FluidLoc Protection: Features internal sealing that prevents fluids from migrating through the cable, enhancing system longevity.
• API 670 Compliance: Meets global industry standards for mechanical and electrical performance in machinery protection systems.
• Universal Interchangeability: Facilitates field replacement without requiring recalibration of the Proximitor sensor.
• Broad Compatibility: Operates seamlessly with both 3300 XL 8mm probes and legacy 3300 series 5mm/8mm transducer components.

Application Guidelines

Technicians should install the 330130-080-10-05 in environments where the cable must traverse significant distances between the machine housing and the junction box. When deploying this cable, ensure that the total length of the probe and extension cable matches the specific calibration of the Proximitor sensor (typically 5 or 9 meters total system length). To prevent connector damage and signal loss, the use of connector silicone grease is recommended during mating. Furthermore, avoid sharp bends in the cable; maintain a minimum bend radius of 25.4 mm (1.0 inch) to prevent internal core damage and ensure consistent vibration data.
