Frequently Asked Questions
Q: Is the probe suitable for hazardous environments? A: Yes. Option 05 provides CSA, ATEX, and IECEx certifications for hazardous area compliance.
Q: What is the recommended installation orientation? A: The probe tip should be aligned perpendicular to the shaft surface to ensure accurate displacement readings.
Q: Does the connector protector improve reliability? A: Yes. It shields the coaxial connection from mechanical stress and environmental contaminants.
Field Installation Guidelines
Confirm gap voltage (-9 VDC to -11 VDC nominal) during commissioning for proper calibration.
Maintain coaxial cable shielding integrity; ground only at the Proximitor end.
Avoid routing probe cables near high-voltage conductors to minimize EMI.
Inspect PPS tip and stainless steel case for mechanical damage before installation.
