3300 XL Proximity System Extension Cable
Model: 330854-040-25-05
Brand Information
Brand: Bently Nevada
Series: 3300 XL Proximity Transducer System (Extension Cable Assemblies)
Product Category: Eddy Current Proximity Measurement System Cable
System Role: Signal transmission between proximity probe and proximitor sensor
The 330854-040-25-05 is a precision-engineered extension cable used in the 3300 XL proximity transducer system. It is designed to carry extremely low-level eddy current signals from the probe to the proximitor sensor while maintaining signal integrity, impedance stability, and electromagnetic protection.
It is widely used in rotating machinery condition monitoring systems where continuous vibration and displacement measurement is required for equipment protection and predictive maintenance.
Product Introduction
The 330854-040-25-05 extension cable is designed to ensure accurate transmission of high-frequency eddy current signals generated by proximity probes. These signals are highly sensitive to noise, impedance mismatch, and mechanical deformation, requiring a highly controlled cable structure.
The cable uses a coaxial architecture with precision impedance matching and multi-layer shielding to ensure that the signal is delivered to the proximitor without distortion or loss.
The “040” configuration indicates a medium-length assembly suitable for standard industrial layouts. The “25-05” suffix defines specific connector and configuration options used in system integration.
This model is commonly applied in turbines, compressors, pumps, generators, and other rotating machinery where continuous monitoring is essential for safe and efficient operation.
