Calibration relies on precise eddy-current probe scaling configured to convert structural displacement into a linear electrical scale factor. Field verification requires validation of the gap voltage validation (-10 VDC targets) near the midpoint of the linear window to guarantee proper dynamic range tracking. This specific alignment enables accurate logging of rotor dynamics parameters, including shaft vibration, position offset, and structural runout. The internal coil geometry is designed for optimal cross-talk suppression, preventing adjacent magnetic fields from distorting the displacement measurements when multiple probes are installed in close physical proximity inside the same bearing housing.\u003c\/p\u003e\n\u003ch3\u003eKit Packaging Manifest\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 21504-012-032-10-02 Proximity Transducer\u003c\/li\u003e\n\u003cli\u003e1 x Coaxial Connector Protective Boot\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003ch3\u003eMechanical Mounting Considerations\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaintain the standard NPT thread or 3\/8-24 mechanical engagement across a minimum of 5 full thread counts during mounting.\u003c\/li\u003e\n\u003cli\u003eVerify the physical unthreaded clearance length prevents the probe tip from contacting the rotating shaft during high-vibration transience.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCable Routing and Strain Relief\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSecure the 1.0 metre coaxial cable along structured paths inside the machine housing to prevent mechanical wear.\u003c\/li\u003e\n\u003cli\u003eAvoid sharp bends or kinks in the armored or unarmored segments; adhere to minimum physical bend radius boundaries.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCalibration and Electrical Isolation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eConfirm the coaxial shell remains electrically isolated from the main machinery housing to prevent ground loops.\u003c\/li\u003e\n\u003cli\u003eUse specialized insulation tape or boot accessories over the miniature male coaxial connector joint.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Engineering FAQ\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the standard target for verifying the eddy-current probe scaling?\u003c\/p\u003e\n\u003cp\u003eCalibration scaling is tuned against a standard AISI 4140 steel target.
