Field verification requires validation of the gap voltage to a benchmark of -10 VDC, centering the signal precisely in the middle of the calibrated linear conversion arc. This bias configuration permits optimal tracking of high-frequency rotor dynamics, including radial vibration and axial position changes. The embedded Click-Loc coaxial connectors maintain rigid impedance matching, which enforces cross-talk suppression between neighboring sensor channels mounted within the same bearing housing.\u003c\/p\u003e\n\u003ch3\u003eKit Composition\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Bently Nevada 330103-00-04-10-11-CN Proximity Probe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2 x Locknuts (3\/8-24 UNF thread profile)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Coaxial connector silicone protection boot\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Installation calibration datasheet\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMechanical Alignment and Grounding Controls\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMechanical Thread Engagement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInspect the mounting port to verify a clean 3\/8-24 UNF thread configuration.
