1. Product Overview
330190-040-00-00 is a 4-meter ETR extended temperature non-armored triaxial extension cable for Bently Nevada 3300 XL 8mm high-temperature eddy current proximity transducer system, specially developed for signal transmission of proximity probes installed around high-temperature turbine casings and hot equipment surfaces.
Adopts PFA ultra-high temperature resistant triaxial insulation and triple-layer copper braided full shielding, stable linear gap signal transmission under long-term continuous high-temperature working conditions, effectively eliminates electromagnetic interference generated by high-power motors and variable frequency drives, avoids measurement drift and signal loss. Equipped with gold-plated Mini ClickLoc self-locking triaxial connectors at both ends, fast plug-and-play field installation; self-locking anti-loose structure prevents connector loosening and signal interruption under severe vibration of turbine bases and compressor frames.
The suffix -00 variant is a general industrial non-intrinsic safety version without global explosion-proof hazardous zone certifications, only applicable to ordinary non-flammable, non-explosive indoor control cabinets of thermal power plants, general machinery factories and cogeneration units. The whole ETR 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 critical high-temperature rotating equipment.
