Description

21747-075-01 is a 7200 series extension cable designed for use in proximity transducer systems. This component serves as the vital link between the proximity probe and the Proximitor sensor, ensuring the transmission of high-frequency carrier signals used in eddy-current displacement measurements. It is engineered to maintain system integrity in critical machinery monitoring applications, including axial position and radial vibration sensing on rotating equipment such as steam turbines, compressors, and large pumps. This configuration features a 7.5 m total length and is constructed to meet the impedance requirements of the 7200 proximity transducer system. It pairs with 7200 series probes and Proximitors to provide a consistent scale factor and linear frequency response across the required measurement range. When installed, it provides a robust connection path for conditioned signals from the Proximitor sensor to monitoring instrumentation, adhering to standard industrial practices for shielded coaxial cabling.

Installation Guidelines

Ensure the extension cable is routed away from high-voltage power lines to prevent electromagnetic interference. Minimize sharp bends and maintain the minimum bend radius specifications to preserve coaxial cable integrity. When connecting the probe and Proximitor, ensure the connectors are clean and properly torqued. Use protective conduit if the cable is routed through areas with potential for physical abrasion or chemical exposure. Grounding should follow standard site practices for Bently Nevada transducer installations to maintain signal shield continuity.
