Description

The Bently Nevada 330930-045-03-00 is a specialized coaxial link component within the 3300 NSv Proximity Transducer System. This physical media link bridges the gap between a 3300 NSv proximity probe and a 3300 XL NSv Proximitor Sensor, ensuring clean transmission of high-frequency eddy current signals. Engineered for systems facing mechanical installation limits like tight counterbores, reduced sideview or rearview spacing, or processing machinery with small target restrictions, the 330930-045-03-00 aids in capturing key variables like fluid-filmed bearing displacement and shaft vibration telemetry.

Configured with a total physical cable length of 4.5 meters, this configuration features fluid-resistant FEP insulation outer protection jackets coupled with integrated connector protectors on the terminal links. The matched electrical design maintains uniform impedance matching along the entire circuit, minimizing signal attenuation and drift. It functions reliably within high-vibration turbomachinery environments to monitor radial vibration, axial position, or tachometer keyphasor timing marks without compromising data integrity.

Features

• High-Impedance Component Matching: Specifically calibrated to function as a matched-length electrical path within the 3300 NSv transducer link.
• Integrated Physical Connector Protections: Outfitted with specialized connector shields to guard fragile terminal joints against moisture contamination and mechanical stress.
• Robust FEP Outer Layer Protective Shielding: Standard Fluorinated Ethylene Propylene insulation jacket provides isolation from synthetic oils and chemical solvents.
• Compact Mechanical Cross-Section: Optimized slim profile facilitates routing through small internal channels or complex housing conduits.

Applications

• Centrifugal air compressors, process gas machinery, and refrigeration industrial compressors.
• Small shaft radial vibration tracking and precision axial thrust alignment applications.
• Tachometer tracking and phase reference Keyphasor timing measurements on tight target surfaces.

Installation Guidelines

• Minimum Bend Radius Protection: Do not bend or crimp the cable past the manufacturer's specified radius limits to avoid altering internal electrical impedance characteristics.
• Connector Integrity Check: Ensure all coaxial interfaces are dry and fully locked. Verify that the integrated protector sleeve fully encloses the joint to keep out conductive fluids.
• Separation From Power Lines: Route the low-voltage extension cable inside grounded metal conduit or segregated trays away from high-current AC motor leads or switching switchgear.
• Cable Strain Relief: Use proper tie-wraps or routing clamps to support the weight of the line, eliminating physical pull stress at the connection nodes during operation.
