Bently Nevada 330730-080-10-00 3300 XL 11 mm Extension Cable

Description

To bridge the critical connection between proximity sensors and monitoring systems, the Bently Nevada 330730-080-10-00 provides high-integrity signal transmission within the 3300 XL 11 mm Proximity Transducer System. This premium extension cable is engineered to deliver low-attenuation performance, maintaining high calibration stability under harsh operating environments. Featuring the FluidLoc cable configuration, it is constructed to prevent the migration of oils, moisture, and other process fluids through the cable interior, ensuring long-term isolation in demanding machinery environments.

Key Features

• FluidLoc technology: Prevents liquid and gas wicking along the cable length.
• Precise Length Calibration: Exact 8.0-meter length designed to meet the electrical length requirements of the 3300 XL 11 mm series.
• Robust Signal Integrity: Optimized capacitance profiles to minimize signal phase shift and amplitude loss.
• Extreme Temperature Resilience: Engineered to withstand continuous exposure in environments ranging from -51 degC to +177 degC.

Applications

• Steam turbine radial vibration and axial thrust measurements.
• Hydroelectric generator shaft displacement tracking.
• Industrial compressor, blower, and gearbox casing monitoring.
• Heavy machinery installations in chemical processing plants.

Connections and Interfaces

Alternative Models & Compatibility

The 330730-080-10-00 extension cable is designed exclusively for the 3300 XL 11 mm series. It is not interchangeable with standard 3300 XL 5 mm or 8 mm systems, as the different probe geometries alter the system's characteristic impedance and calibration settings. Mixing cables across series will result in severe measurement inaccuracies or calibration faults at the Proximitor.

Application Pitfalls & Engineering Notes

When routing the 330730-080-10-00, observe the minimum bend radius requirements to prevent internal degradation of the coaxial core and shield layers. Although the FluidLoc jacket restricts longitudinal fluid penetration inside the cable, do not allow the coaxial connectors to remain submerged in stagnant fluids without proper physical sealing (such as heat-shrink tubing or connector protector kits).

Commissioning & Wiring Tips

Before mating the miniature coaxial connectors, ensure they are free of dirt, grease, and moisture. Clean only with electronics-grade isopropyl alcohol if contaminated. Hand-tighten the connectors until they click or bottom out firmly; do not use pliers or standard hand tools which can strip the internal threads or crush the delicate gold-plated center pins.
