Frequently Asked Questions

Q: Is this probe suitable for hazardous environments? A: Yes. Option 05 provides CSA, ATEX, and IECEx certifications for hazardous area compliance.

Q: What is the nominal scale factor? A: Approximately 7.87 V/mm (200 mV/mil), ensuring linear displacement measurement.

Q: Can the probe be used for both static and dynamic measurements? A: Yes. It measures static shaft position and dynamic vibration simultaneously.

Field Installation Guidelines

• Install probe tip perpendicular to shaft surface for accurate displacement measurement.
• Maintain coaxial cable shield integrity; ground only at the Proximitor end.
• Avoid routing probe cables near high-voltage conductors to reduce EMI.
• Confirm gap voltage (-9 VDC to -11 VDC nominal) during commissioning for proper calibration.
• Inspect probe case and connector for mechanical integrity before installation.
