Eddy-Current Probe Scaling and Gap Voltage Validation

The housing assembly is engineered to maintain calibrated eddy-current probe scaling by ensuring precise mechanical alignment of the probe tip. Gap voltage validation at -10 VDC reference points is supported through stable penetration depth, enabling accurate shaft displacement monitoring. Coaxial shielding and reducer fittings suppress cross-talk and maintain electrical integrity in multi-channel installations.

Frequently Asked Questions

Q: Can the housing assembly be installed in hazardous zones without additional certification? A: Yes. The assembly is explosion-proof and meets CSA Type 4 and API 670 standards, suitable for hazardous industrial areas.

Q: Does the 14.4 in penetration depth require special calibration? A: No. The penetration depth is mechanically defined; calibration is performed at the proximitor level.

Q: Are reducer fittings interchangeable? A: Reducer fittings are supplied with multiple grommet sizes to accommodate cable variations but must remain within specified NPT thread standards.

Field Installation Guidelines

  • Engage 3/4-14 NPT threads with a minimum of 5 turns to ensure mechanical stability.
  • Ground shielding at the proximitor end only to prevent ground-loop interference.
  • Verify sealing integrity of the cable grip and grommet to maintain explosion-proof rating.
  • Route cables away from high-voltage conductors to minimize induced noise.
  • Confirm compliance with API 670 and CSA Type 4 requirements before energizing the system.
