During commissioning, gap voltage validation (-10 VDC targets) must be verified using a calibrated digital multimeter at the probe terminal layer to position the sensor precisely within the linear center of the RF magnetic field. Correct calibration minimizes cross-talk suppression failures when multiple transducers are positioned in close proximity around the rotor bearing housing. Accurate tracking of high-frequency shaft displacements provides reliable orbital plots for real-time analysis of complex rotor dynamics.\u003c\/p\u003e\n\u003ch3\u003ePackage Component List\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) integrated PROXPAC XL assembly including internal proximity probe and transducer electronics.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) silicon fluid-resistant sealing gasket for conduit connection ports.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) installation manual containing calibration graphs and factory verification certificates.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eOn-Site Deployment and Wiring Rules\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eShield Grounding:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eTerminal connections must isolate shield wires from the transducer housing body.
