Frequently Asked Questions
Q: Can the armored probe be used in high-vibration environments? A: Yes. The armored design provides mechanical protection and durability in harsh industrial conditions.
Q: What is the nominal scale factor? A: Approximately 7.87 V/mm (200 mV/mil), ensuring linear displacement measurement.
Q: Are hazardous area certifications included? A: Yes. CSA, ATEX, and IECEx approvals are provided under option05.
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 (-10 VDC nominal) during commissioning for proper calibration.
