3300 XL Proximity System Extension Cable
Model: 330854-080-25-00
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 330854-080-25-00 is a long-distance extension cable used in the 3300 XL proximity transducer system. It is designed to transmit low-level eddy current signals from the proximity probe to the proximitor sensor while maintaining high signal fidelity, impedance stability, and strong electromagnetic interference protection.
It is widely applied in rotating machinery monitoring systems where long cable routing is required between sensor locations and monitoring cabinets.
Product Introduction
The 330854-080-25-00 extension cable is engineered for precise signal transmission in eddy current-based vibration monitoring systems. Because proximity probe signals operate at very low amplitudes, they are highly sensitive to noise, grounding issues, and impedance mismatch.
To ensure accurate signal delivery, this cable uses a coaxial structure with controlled impedance and multi-layer shielding. This design minimizes signal degradation and ensures stable transmission even in harsh industrial environments.
The “080” configuration indicates a longer cable length suitable for large industrial installations such as turbine halls, compressor stations, and distributed monitoring systems. The “25-00” configuration defines connector and assembly specifications within the system.
This model is commonly used in power generation, oil & gas, petrochemical, and heavy industrial applications.
