The Bently Nevada 330930-045-00-05 is a 4.5-meter (14.8-foot) extension cable designed for the 3300 NSv (Near-shielded) Proximity Transducer System. This cable serves as the critical link between the 3300 NSv proximity probe and the 3300 XL NSv Proximitor Sensor, enabling precise vibration and position monitoring in industrial rotating machinery.

Features

• Designed for applications with restricted installation space, such as counterbore or side-view constraints.
• Features high-reliability, gold-plated brass ClickLoc connectors for corrosion-resistant, secure signal transmission.
• Constructed with 75 Ohm coaxial cable and FEP insulation for consistent electrical performance.
• Compatible with legacy 3300 RAM transducer systems and specific 3000/7000-series 190 transducer systems.
• Standard unarmored configuration with multiple agency approvals for hazardous area operations.

Applications

• Fluid-film bearing machines, including radial vibration and axial thrust monitoring.
• Centrifugal air, refrigeration, and process gas compressors.
• Turbo expanders and high-speed turbines.
• Electric motors and generators with tight internal clearances.
• Centrifugal pumps and fans requiring mounting between bearing pads.

Technical Specifications

Installation Guidelines

• System Length Matching: The total length of the probe integral cable plus the extension cable must match the calibrated length of the Proximitor Sensor (typically 5 meters total). Using a 4.5m extension with a 0.5m probe is the standard configuration.
• Handling: Do not overtighten cable ties, as crushing the coaxial dielectric can induce signal noise or "ghost" vibration readings.
• Bending: Maintain a minimum bend radius of at least 25.4 mm (1.0 inch).
• Environment: Ensure all connections are made in a clean, dry environment to prevent moisture ingress into the coaxial interface.

FAQ

What is the primary role of this cable?

It transmits high-frequency signals between the proximity probe and the Proximitor sensor, allowing the system to monitor the gap between the probe tip and the target surface for vibration and position analysis.

Can this cable be used with 3300 XL standard probes?

No, this cable is specifically part of the 3300 NSv (Near-shielded) system. It is designed to work with NSv components to ensure the correct linear range and scale factor.

Is this part still supported?

Yes, we continue to provide support and supply for this component, even if it has reached End-Of-Life (EOL) status with the original manufacturer.
