Eddy-Current Probe Scaling and Gap-Voltage Validation
Within NSv rotor-dynamic monitoring systems, the extension cable preserves calibrated eddy-current probe scaling. Controlled coaxial impedance ensures gap voltage validation at nominal -10 VDC targets. Stainless steel armor and FEP insulation suppress cross-talk by stabilizing shield continuity and reducing electromagnetic coupling.
Frequently Asked Questions
Q: Can the cable be field-cut or re-terminated? A: No. Factory termination preserves impedance, capacitance, and probe calibration.
Q: Does the stainless steel armor affect electrical performance? A: The armor provides mechanical protection only; coaxial impedance and capacitance remain stable.
Q: What is the impact of cable length on probe linearity? A: NSv systems are calibrated for defined lengths. The 060 option maintains the intended transfer function and gap-voltage scaling.
Field Installation Guidelines
- Route away from high-frequency drives or switching conductors to minimize induced noise.
- Maintain shield bonding at designated termination points; avoid multiple ground references.
- Respect minimum bend radius to prevent coaxial geometry distortion.
- Verify connector seating torque before energizing the transducer system.
- Do not mix NSv cabling with XL cabling to avoid impedance mismatch.
