Proper scaling requires adherence to the nominal sensitivity of 7.87 mV\/µm (200 mV\/mil). Calibration must be performed against the specified target material (typically AISI 4140 steel) to ensure linear output. The system requires a nominal -10 VDC gap voltage bias for linear operation within the designated 0 mm to 12.7 mm (500 mil) linear range. Cross-talk suppression is maintained through integrated radio-frequency shielding to prevent interference in high-density probe installations.\u003c\/p\u003e\n\u003ch3\u003eDelivery Components\u003c\/h3\u003e\n\u003col class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 x 3300 XL 25 mm Proximity Probe (with integral cable and armor)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Certificate of Conformance \/ Regulatory documentation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eMounting and Signal Integration\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMechanical Positioning\u003c\/strong\u003e: Ensure the probe tip is installed perpendicular to the target surface.
