Frequently Asked Questions

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

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

Q: Can this 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 readings.
• Maintain coaxial shielding integrity; ground only at the Proximitor end.
• Route probe cables away from high-voltage conductors to minimize EMI.
• Confirm gap voltage (–9 VDC to –11 VDC nominal) during commissioning.
• Inspect probe case and connector for mechanical integrity before installation.
