Bently Nevada 21747-080-01 7200 Series Extension Cable

Description

The 21747-080-01 is a 7200 Series extension cable, configured with an 8.00-metre length and integrated stainless steel armor. This coaxial extension cable serves as a critical link in the Bently Nevada 7200 proximity transducer system, connecting the proximity probe to the Proximitor sensor. By maintaining signal integrity in demanding industrial environments, this cable ensures accurate transmission of static and dynamic displacement measurements for machine condition monitoring.

This specific configuration, utilizing Option 080 for length and Option 01 for armor, provides the necessary physical protection required for installations subject to abrasion or mechanical stress. The cable is designed for use with 7200 series proximity probes and Proximitors, supporting stable operation in temperature ranges up to +177 degC. It is commonly employed in applications involving rotating and reciprocating machinery, including gas and steam turbines, compressors, pumps, and centrifuges, where reliable axial thrust and radial vibration data are essential for maintenance.

Installation Guidelines

Ensure that the extension cable is routed to avoid sharp bends, which can stress the coaxial structure and degrade signal performance. When installing the armored variant, ensure proper securing of the armor at termination points to prevent vibration-induced wear. Avoid routing near high-voltage lines to minimize electromagnetic interference. Maintain connection integrity by ensuring all miniature coaxial connectors are clean and fully seated during system assembly.

Compliance and Certifications

The 7200 series proximity transducer systems comply with established industry standards for hazardous locations, including certifications from CSA, BASEEFA, and FM. Users should verify specific hazardous area requirements against the plant safety documentation and the corresponding 7200 series data sheets for the applicable system components.
