The 330930-040-03-05 is a 3300 NSv Extension Cable designed for use within the 3300 XL NSv Proximity Transducer System. This extension cable serves as a critical component in systems designed for centrifugal air compressors, refrigeration compressors, and process gas compressors, particularly in installations where space constraints (such as counter bore or side-view limitations) restrict the use of standard transducer systems. The 3300 NSv extension cable is mechanically and electrically compatible with Bently Nevada's previous 3300 RAM proximity transducer components.

Features

• Compatibility: Mechanically and electrically compatible and interchangeable with previous 3300 RAM proximity extension cables.
• Connector Design: Features gold-plated brass ClickLoc connectors that lock into place to prevent loosening during operation.
• Cable Construction: Designed for robust performance with high-quality coaxial cabling.
• Connector Protection: Includes a connector protector (as specified in this model code) to prevent liquids from entering the ClickLoc connectors and affecting electrical signals.
• System Integration: Designed to work as part of the 3300 XL NSv system, which features an Average Scale Factor of 7.87 V/mm (200 mV/mil).

Applications

The 3300 XL NSv transducer system is typically utilized in the following fluid-filmed bearing machine applications:

• Radial vibration and radial position measurements 
• Axial (thrust) position measurements 
• Tachometer and zero speed measurements 
• Phase reference (Keyphasor signals)

Installation Guidelines

• System Integration: Ensure the combined length of the extension cable and the probe matches the required 3300 XL NSv Proximitor Sensor total system length.
• Handling: While components are robust, take standard precautions to avoid electrostatic discharge during handling of connectors.
• Connection: Utilize the included connector protectors on the probe-to-extension cable and cable-to-Proximitor Sensor connections to prevent liquid ingress.
• Torque: ClickLoc connectors should be finger-tightened to ensure proper locking.
• Field Wiring: For the Proximitor Sensor, use three-conductor shielded triad cable (0.2 to 1.5 mm2) with a maximum length of 305 meters (1,000 feet) to the monitor.
