This high-frequency physical interaction provides real-time tracking of rapid shaft oscillations. To ensure correct integration with rotating machinery, a gap voltage validation is required during field setup. By adjusting the physical mechanical gap until the system output registers the nominal -10 VDC target, the probe is centered in its linear operating region.\u003c\/p\u003e\n\u003cp\u003eThis precise positioning is critical for recording rotor dynamics parameters, such as radial shaft vibration and axial thrust position, while preventing signal saturation on the associated 7200 Series monitor modules.\u003c\/p\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Bently Nevada 21504-16-32-10-02 Proximity Probe\u003c\/li\u003e\n\u003cli\u003e2 x 3\/8-24 Locknuts\u003c\/li\u003e\n\u003cli\u003e1 x Thread protective cap\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eThread Mechanical Clearances\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEnsure the 3\/8-24 UNF threads on the probe case and mounting bracket are clean and free of burrs.
