Description

The Bently Nevada 330130-085-00-00 is an electrical hardware component designed for use within the 3300 XL 8 mm Proximity Transducer System. It serves as the physical and electrical bridge linking a 3300 XL 8 mm proximity probe to a 3300 XL Proximitor Sensor to capture non-contact displacement data. The extension cable facilitates the low-loss transmission of high-frequency eddy current signals, which are critical for monitoring radial vibration, axial position, and timing indicators on industrial machinery components. It is engineered to maintain balanced system impedance across the entire link, ensuring precise metrics without requiring individual component calibration.

This specific configuration features an overall length of 8.5 meters (27.9 feet) and is constructed with a standard triaxial coaxial configuration to maintain electrical shielding against ambient noise. The 330130-085-00-00 extension cable is backward compatible with legacy non-XL 3300 series proximity systems, allowing direct hardware integration into established turbomachinery monitoring enclosures. It is widely used on rotating apparatus including high-speed compressors, steam turbines, and industrial gearboxes where reliable sensor loops are required for machinery protection.

Features

• Full Hardware Interchangeability: Designed to allow seamless substitution of components within the 3300 XL series without bench calibration or matching.
• Backward System Compatibility: Interfaces directly with legacy non-XL 3300 series 5 mm and 8 mm components to minimize upgrade costs.
• High Pull Strength Architecture: Outfitted with standard gold-plated ClickLoc connectors providing robust environmental and physical retention.
• Standard Outer Insulation: Constructed using a high-durability fluoroethylene propylene (FEP) jacket for reliable protection against common chemical exposure.
• Shielded Coaxial Construction: Employs a 75 ohm triaxial design to minimize electromagnetic interference (EMI) and radio frequency interference (RFI).

Applications

• Vibration Monitoring Loops: Connection of proximity sensors within fluid-film bearing housings on heavy rotating assets.
• Axial Position Detection: Extension of sensor signal paths from thrust bearings to distant terminal enclosures.
• Tachometer and Speed Systems: Bridging Keyphasor probe signals to rack-mounted monitoring systems for phase angle tracking.
• Harsh Industrial Processing: Applied across petrochemical refining plants, offshore power production platforms, and processing plants.

Installation Guidelines

• Loop Configuration: Confirm that the combined length of the selected proximity probe and this extension cable equals the total calibrated length specification of the corresponding Proximitor Sensor.
• Connector Tightening: Connection between two 3300 XL gold ClickLoc connectors must be made finger-tight. Do not use mechanical pliers on these interfaces to prevent mechanical distortion.
• Mating Dissimilar Connectors: When joining a non-XL stainless steel connector to a 3300 XL connector, tighten finger-tight plus 1/8 turn using pliers for a verified seal.
• Moisture Protection: Wrap the joined connections using the included silicone tape or install an optional plastic connector protector to prevent environmental fluid intrusion.
• Cable Routing Protection: Observe the minimum permissible bend radius specifications during field routing to protect internal triaxial conductors from structural fatigue.
