Dynamics Integration\u003c\/h3\u003e\n\u003cp\u003eThe 21504-32-56-10-02 probe relies on eddy-current probe scaling to convert physical gap changes into high-fidelity electrical signals. When excited by a 7200 Series Proximitor Sensor, the probe tip generates an RF magnetic field. Target movements on the rotating shaft interrupt this field, causing proportional voltage variations that monitor complex rotor dynamics, including radial vibration and axial thrust displacement.\u003c\/p\u003e\n\u003cp\u003eTo prevent signal degradation and cross-talk, the probe requires careful gap voltage validation. Physical adjustment of the 3\/8-24 mounting thread is required until the static gap voltage reads a nominal -10 VDC at the Proximitor. This positions the target at the exact center of the 2.0 mm (80 mils) linear operating range, maintaining a stable 200 mV\/mil scale factor and suppressing cross-talk on closely spaced sensor arrays.\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 21504-32-56-10-02 Proximity Probe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2 x Integral hex jam nuts\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\u003eThread Depth and Locknut Tension\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInstall the probe into the mounting brackets, taking care to maintain the 3.2 in unthreaded portion clear of obstructions.
