1. Product Overview

330130-045-00-05 is a 4.5-meter standard unarmored extension cable for Bently Nevada 3300 XL 8mm eddy current proximity transducer system, dedicated to transmitting high-frequency gap measurement signals between proximity probe and proximitor monitor module. Double copper braided shielding structure effectively eliminates electromagnetic interference generated by high-power motors, variable frequency drives and heavy industrial equipment, ensuring stable linear vibration and shaft axial displacement measurement signals. Equipped with ClickLoc quick-lock coaxial connectors at both ends for fast plug-and-play field installation; self-locking anti-loose structure prevents signal disconnection under severe vibration of turbine bases and compressor frames. The -05 suffix variant carries complete international intrinsic safety explosion-proof certifications ATEX/IECEx/CSA, applicable to petrochemical refineries, offshore oil & gas platforms and all Zone 0/1/2 flammable gas hazardous control cabinets. The whole transducer system supports full interchangeability of probe, extension cable and proximitor without additional calibration work after cable replacement, significantly reducing on-site maintenance downtime. Matched with 3500 rack machinery protection system to realize real-time continuous monitoring of bearing radial vibration, thrust axial displacement and Keyphasor rotational speed for all critical rotating equipment.
