Target calibration requires gap voltage validation targeting -10 VDC at the physical center of the linear range (typically corresponding to approximately 1.0 mm or 40 mils gap setting when referenced to an AISI 4140 steel target). The system exhibits strict eddy-current probe scaling to suppress channel-to-channel cross-talk and maintain flat frequency response characteristics across high-speed rotor dynamics monitoring loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the procedure for verifying the gap voltage during probe physical setup?\u003c\/p\u003e\n\u003cp\u003eA: Connect the probe cable to the extension cable and Proximitor Sensor powered by -24 VDC. Measure the DC voltage between the Proximitor \"Out\" and \"Com\" terminals using a digital multimeter. Adjust probe thread engagement until the gap voltage reaches the nominal target of -10.0 VDC (corresponding to mid-span gap), then torque the mounting locknut.\u003c\/p\u003e\n\u003cp\u003eQ: Can the 9.0 meter probe cable be shortened or spliced directly in the field?\u003c\/p\u003e\n\u003cp\u003eA: No. Cutting or splicing the coaxial cable alters total system capacitance and inductance, causing system calibration failure and severe sensitivity deviations. The exact total system electrical length must be strictly maintained.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Mounting \u0026amp; Sealing\u003c\/strong\u003e: Thread the probe casing into the target mounting port. Ensure the Viton O-ring is properly seated to maintain differential pressure sealing between the probe tip and case.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Assembly\u003c\/strong\u003e: Crimp and lock the miniature coaxial ClickLoc connector.
