The probe coil projects an RF field into the target area, converting gap distance changes into continuous voltage variations. This electromagnetic loop tracking provides real-time data on complex rotor dynamics, including radial shaft vibration and axial thrust position.\u003c\/p\u003e\n\u003cp\u003eTo establish proper measurement scaling, the gap voltage validation must be performed during physical installation. By adjusting the probe's depth until the Proximitor output measures -10 VDC, the system is centered within its 2.0 mm linear range. Correct physical alignment minimizes electrical distortions and achieves cross-talk suppression between adjacent probes installed on the same machinery plane.\u003c\/p\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Bently Nevada 21505-00-28-05-02 Proximity Probe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2 x Hex locknuts for standard mounting\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVerifying Probe Side Clearance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eMaintain a minimum radial side clearance of 8.9 mm (0.35 in) between the probe tip and any surrounding metal surfaces to prevent interference with the electromagnetic field.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRouting and Cable Protection\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAvoid routing the 0.5 m integrated coaxial cable near high-voltage lines.
