3300 XL Proximity System Extension Cable
Model: 330854-080-25-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 330854-080-25-CN is a long-distance extension cable used in the 3300 XL proximity transducer system. It is designed to transmit weak eddy current signals from the proximity probe to the proximitor sensor while maintaining stable impedance, low noise, and strong electromagnetic interference resistance.
The “CN” suffix generally indicates a regional configuration variant, while maintaining full compatibility with the standard 3300 XL system architecture.
Product Introduction
The 330854-080-25-CN extension cable is engineered for high-precision signal transmission in rotating machinery monitoring systems. Eddy current probe signals are extremely low-level and highly sensitive to electrical noise, grounding variation, and mechanical stress.
To ensure signal integrity, the cable adopts a coaxial structure with controlled impedance and multi-layer shielding. This allows stable transmission even in electrically noisy industrial environments.
The “080” configuration indicates a longer cable length suitable for large industrial installations such as turbine halls and distributed compressor systems where distance between probe and monitoring system is significant.
It is widely used in power generation, petrochemical plants, oil & gas facilities, and heavy industrial machinery monitoring systems.
