Bently Nevada 21747-045-00 7200 Series Extension Cable

Description

The 21747-045-00 is an unarmored extension cable designed for use within the Bently Nevada 7200 Proximity Transducer System. This 4.5 metre cable facilitates the signal transmission between the 7200 proximity probe and the Proximitor sensor, ensuring proper electrical continuity and signal integrity for critical machinery monitoring applications. As a component of the 7200 system, this cable is engineered to maintain system calibration and performance standards for radial vibration and axial position measurements. It is compatible with 7200 series probes and Proximitors, supporting system configurations where a 4.5 metre extension is required. This specific configuration (Option 045 for length and Option 00 for armor) provides a standard, unarmored solution for environments where physical abrasion protection is not required.

Features

• 4.5 metre total system length extension capability
• Unarmored construction for standard industrial mounting environments
• Compatible with Bently Nevada 7200 series 5 mm and 8 mm proximity transducer systems
• Maintains system scale factor and linearity when used as part of a calibrated 7200 monitoring loop
• Constructed for harsh environmental resilience within specified temperature limits

Applications

• Radial vibration monitoring on rotating machinery
• Axial thrust position measurement
• Eccentricity and rotor bow analysis
• Gas and steam turbine monitoring
• Compressor and centrifugal pump diagnostics

Installation Guidelines

Ensure all coaxial connections are clean and fully tightened to maintain the required electrical contact and shielding integrity. Route the extension cable through conduit or appropriate cable trays to minimize potential for physical damage or electromagnetic interference. Avoid sharp bends that exceed the cable's minimum bend radius. Grounding and shielding practices should adhere to the site-specific installation diagrams provided for the 7200 transducer system.
