This physical interaction is essential for analyzing rotor dynamics, including high-speed shaft vibration and axial position tracking.\u003c\/p\u003e\n\u003cp\u003eDuring field setup, gap voltage validation is required to ensure the probe resides in the center of its 2.0 mm linear range. Technicians must adjust the physical distance of the probe tip relative to the shaft surface until the nominal output voltage reaches a target of -10 VDC. This calibration process maintains precise signal scaling across the 10 kHz bandwidth and suppresses cross-talk interference from adjacent sensors.\u003c\/p\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Bently Nevada 21505-00-59-10-02 Proximity Transducer\u003c\/li\u003e\n\u003cli\u003e2 x Hex mounting nuts\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\u003eMechanical Thread Alignment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEnsure the 3\/8-24 threads are clean and free of burrs before insertion.
