Eddy-Current Probe Scaling and Rotor Dynamics
The extension cable maintains calibrated eddy-current probe scaling across NSv systems. Controlled impedance ensures gap voltage validation at -10 VDC reference points. FluidLoc® sealing prevents axial fluid migration, preserving rotor dynamics monitoring integrity. Stainless steel armor stabilizes shielding continuity, suppressing cross-talk between adjacent coaxial runs.
Frequently Asked Questions
Q: Can the 330930-065-01-05 be used in submerged environments? A: No. It is rated for 100% condensing humidity but not continuous submersion.
Q: Does FluidLoc® sealing affect impedance? A: No. FluidLoc® provides mechanical sealing only; electrical characteristics remain unchanged.
Q: How does cable length affect calibration? A: Probe, cable, and Proximitor must match factory-defined lengths. The 065 option is intended for 7.0 m total system configurations.
Field Installation Guidelines
- Maintain minimum bend radius: 25.4 mm unarmored, 30.5 mm armored.
- Bond shielding at the Proximitor end only to avoid ground loops.
- Protect connectors from fluid ingress; FluidLoc® provides axial sealing but not external connector sealing.
- Route away from high-current conductors to minimize electromagnetic interference.
- Verify total system length compliance before energizing the transducer system.
