3300 XL Proximity System Extension Cable
Model: 330854-040-24-CN
Brand Information
Brand: Bently Nevada
Series: 3300 XL Proximity Transducer System (Extension Cable Assemblies)
Product Category: Industrial Coaxial Extension Cable for Eddy Current Vibration Monitoring Systems
System Role: Signal Transmission Link between Proximity Probe and Proximitor Sensor
The 330854-040-24-CN is an industrial-grade extension cable designed for use in the 3300 XL proximity transducer system. It is used to transmit weak eddy current signals from a proximity probe to a proximitor sensor while maintaining signal accuracy, stability, and electromagnetic protection.
The “CN” suffix typically indicates a regional or compliance-specific configuration variant while maintaining full electrical and mechanical compatibility with the standard 3300 XL system architecture.
Product Introduction
The 330854-040-24-CN extension cable is a key component in rotating machinery condition monitoring systems. It ensures that high-frequency signals generated by eddy current proximity probes are transmitted accurately to the signal conditioning module without distortion or loss.
Because the signal levels in eddy current systems are extremely low, the cable must maintain precise impedance control and strong electromagnetic shielding to avoid noise interference.
The 040 length configuration is commonly used in medium-distance installations where the probe is mounted inside machinery and the proximitor is installed in a control cabinet or protection system panel.
This cable is widely applied in turbines, compressors, pumps, generators, and other critical rotating equipment where continuous vibration and displacement monitoring is required.
