3300 XL Proximity System Extension Cable
Model: 330854-040-25-CN
Brand Information
Brand: Bently Nevada
Series: 3300 XL Proximity Transducer System (Extension Cable Assemblies)
Product Category: Eddy Current Proximity Measurement Extension Cable
System Role: Signal transmission between proximity probe and proximitor sensor
The 330854-040-25-CN is a high-reliability extension cable used in the 3300 XL proximity transducer system. It is designed to transmit low-level eddy current signals with high accuracy while maintaining impedance stability and strong electromagnetic shielding.
The “CN” suffix typically indicates a region-specific configuration variant, while retaining full compatibility with the standard 3300 XL system architecture.
Product Introduction
The 330854-040-25-CN extension cable is engineered for precise signal transmission in rotating machinery monitoring systems. It carries weak high-frequency signals generated by proximity probes to the proximitor sensor without distortion or signal degradation.
Because eddy current signals are extremely sensitive to noise and impedance variation, the cable is designed with controlled coaxial geometry and multi-layer shielding to ensure stability.
The “040” configuration represents a medium-length assembly suitable for standard industrial layouts, while the “25-CN” defines connector and regional configuration characteristics.
It is widely used in turbines, compressors, pumps, generators, and other rotating machinery requiring continuous vibration and displacement monitoring.
