3300 XL Proximity System Extension Cable
Model: 330854-040-25-00
Brand Information
Brand: Bently Nevada
Series: 3300 XL Proximity Transducer System (Extension Cable Assemblies)
Product Category: Eddy Current Proximity System Extension Cable
System Role: Signal transmission between proximity probe and proximitor sensor
The 330854-040-25-00 is an industrial-grade extension cable used in the 3300 XL proximity transducer system. It is designed to transmit low-level eddy current signals from a proximity probe to a proximitor sensor with high accuracy and minimal interference.
This cable plays a critical role in rotating machinery protection systems where continuous vibration, displacement, and position monitoring are required.
Product Introduction
The 330854-040-25-00 extension cable is engineered to maintain signal integrity in eddy current proximity measurement systems. These signals are extremely sensitive to electromagnetic noise, impedance mismatch, and mechanical stress, so the cable is designed with precise coaxial geometry and advanced shielding.
The “040” configuration indicates a medium-length cable suitable for standard industrial installations. The “25-00” configuration defines connector and assembly options within the system design.
It is commonly installed in turbine systems, compressors, pumps, generators, and other rotating equipment where reliable condition monitoring is essential for operational safety and predictive maintenance.
