Proper gap voltage validation is required during installation, targeting standard mid-range values (typically -10 VDC) to maintain the linear operating region of the sensor. The system requires cross-talk suppression by maintaining appropriate physical separation between adjacent probes on the same shaft, preventing interference in the high-frequency oscillation field. Rotor dynamics data captured by this sensor must be verified against mechanical runout standards to ensure measurement accuracy.\u003c\/p\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003ePR6423\/002-131 Eddy Current Sensor (CON041 version)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThreaded lock nuts for mounting adjustment\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTechnical installation sheet\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eProtective dust cap for connector interface\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMounting\u003c\/strong\u003e: Utilize the threaded body for fine-tuned gap distance calibration relative to the target shaft;
