The GE / Bently Nevada 21747-085-00 is an 8.5-meter extension cable engineered to extend proximity probes within the Bently Nevada 7200 Proximity Transducer System. This 3-conductor shielded cable maintains signal integrity and power delivery between 7200 proximitors and Bently Nevada monitoring systems, enabling probe placement at extended distances from transducer modules. The cable operates on eddy current sensing principles across a 0 Hz to 10 kHz frequency range with an 80 mil (2 mm) linear measuring range, supporting both 5 mm and 8 mm proximity transducer configurations.
Designed for industrial machinery monitoring in demanding environments, the 21747-085-00 delivers non-contact measurements of shaft position, vibration, radial motion, axial thrust, rotor eccentricity, and rotor stability. Metal connectors and industrial-grade construction with basic jacket design ensure durability in harsh operating conditions. Installation requires maintaining 15 cm clearance from hot surfaces, 50 mm minimum bend radius, proper shielding in wet areas, and adequate cable grounding.
