When setting up the mechanical gap loops, technicians must perform gap voltage validation to anchor the baseline target output at -10 VDC, matching the core of the linear calibration scale. This baseline calibration is necessary to properly isolate high-frequency rotor dynamics, tracking rapid movements without signal distortion. The mechanical layout incorporates integrated insulation matrices to provide cross-talk suppression when multiple NSv sensors are deployed in close physical proximity on small-scale bearing blocks.\u003c\/p\u003e\n\u003ch3\u003ePackage List\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Bently Nevada 330905-00-05-05-02-CN Proximity Probe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2 x Mounting locknuts (3\/8-24 UNF thread profile)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Silicone coaxial interface protection boot\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Calibration and compliance certificate\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMechanical Mounting and Wiring Directives\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eThread Mounting Depth\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEnsure the receiving port matches the 3\/8-24 UNF thread specifications.
