The system relies on precise eddy-current probe scaling to ensure that the output voltage remains linear relative to the gap distance. Operators must ensure gap voltage validation is maintained at the -10 VDC nominal operating point to prevent signal clipping at the monitor input. In high-density mounting arrays, cross-talk suppression is maintained by adhering to minimum spatial separation requirements to avoid interference from the high-frequency carrier signal.\u003c\/p\u003e\n\u003ch3\u003eOrdering Info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) 21504-00-32-10-02 Proximity Probe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIntegrated coaxial lead with standard connector\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTwo (2) 3\/8-24 UNF stainless steel lock nuts\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCalibration documentation for standard 4140 steel target\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\u003eMounting Alignment:\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eInstall the probe perpendicular to the shaft centerline to ensure output linearity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eUse a depth micrometer to achieve the required mechanical gap prior to securing lock nuts.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003e\n\u003cp\u003eTermination and Shielding:\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eEnsure the connector is fully seated to prevent signal noise from intermittent contact.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRoute signal cables through dedicated grounded conduit to minimize electromagnetic interference (EMI).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003e\n\u003cp\u003eGrounding:\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eEnsure the stainless steel probe body maintains electrical continuity with the machine chassis to provide a reference ground for the coaxial shield.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eWhat happens if the gap is set outside the linear range?\u003c\/p\u003e\n\u003cp\u003eSetting the gap outside the linear range leads to signal distortion or saturation, resulting in incorrect vibration or displacement readings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan this probe be used for speed measurement?\u003c\/p\u003e\n\u003cp\u003eYes, the probe generates a pulse signal when detecting surface discontinuities like keyways or notches, suitable for speed-sensing modules.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow is electrical isolation maintained?\u003c\/p\u003e\n\u003cp\u003eThe probe tip is electrically isolated from the metal housing, which prevents the formation of ground loops that could introduce noise into the TSI system.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIs the probe cable length field-modifiable?\u003c\/p\u003e\n\u003cp\u003eNo. The coaxial cable is factory-matched to the system impedance.
