This displacement is translated into a precise voltage output relative to the gap between the probe tip and the target shaft. During mechanical calibration, field technicians perform a gap voltage validation (-10 VDC target representing the physical center of the linear range) to align the rotor dynamics measurement system.\u003c\/p\u003e\n\u003cp\u003eTo prevent cross-talk suppression failures when multiple probe systems are installed in close physical proximity, the housing ensures proper spatial separation and structural shielding.
