Hardware Specifications

Rotor Dynamics & Eddy-Current Transducer Metrics

The extension cable functions as an integral transmission path within the eddy-current measurement circuit, maintaining correct electrical impedance matching to ensure precise eddy-current probe scaling. Gap voltage validation must be performed during initial commissioning to confirm baseline outputs adhere strictly to nominal target parameters. Proper signal propagation relies on maintaining low loop resistance to prevent phase shift errors during dynamic rotor vibration tracking. Furthermore, cross-talk suppression techniques, including continuous shield continuity and optimized cable routing away from high-voltage AC conductors, protect high-resolution shaft displacement signals from external electromagnetic interference.

Delivery Scope

• 1 x Bently Nevada 330190-080-00-00 3300 XL Extended Temperature Range Extension Cable
• 1 x ClickLoc connector protective cap assembly
• 1 x Technical installation instruction sheet

Physical Installation Guidelines

• Route the coaxial extension cable away from heavy motor power cables and variable frequency drives to prevent electromagnetic signal coupling.
• Secure the ClickLoc connector firmly to ensure mechanical locking and maintain environmental sealing against moisture ingress.
• Ground the outer metallic shield at the monitor rack side only, leaving the probe side floating to eliminate ground loops.
• Avoid sharp bending radii during installation to preserve the structural integrity of the coaxial conductor and dielectric core.
