When the probe tip interacts with a rotating shaft, magnetic field variations generate eddy currents that alter the system impedance. For accurate rotor dynamics analysis, the initial physical installation must balance the gap voltage validation to approximately -10 VDC targets, which represents the midpoint of the linear calibration envelope. Cross-talk suppression is achieved through precise cable length matching, preventing signal interference between adjacent probes measuring orthogonal (X-Y) radial vibration planes.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 330703-000-040-10-11-00 Proximity Probe with integrated 1.0 m coaxial cable\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2 3\/8-24 UNF Hex Jam Nuts\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 ClickLoc Connector Protector Cap\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 Installation Sheet\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMechanical Installation and Cabling\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eThread Engagement and Torque\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eMount the probe through a clear 3\/8-24 threaded hole, verifying a minimum of 5 full threads of engagement to achieve mechanical stability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTighten the locknuts to a maximum torque specification of 10.7 N-m (95 in-lb) to prevent housing deformation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRouting Limits and Shielding\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eMaintain a minimum bend radius of 25.4 mm (1.0 in) along all sections of the coaxial cable to protect internal conductors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eRoute probe leads inside dedicated, grounded conduit, keeping them isolated from high-voltage AC lines to prevent EMI injection.\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 is the standard gap voltage required for calibration?\u003c\/p\u003e\n\u003cp\u003eThe probe must be physically gapped to yield a baseline output of -10 VDC from the connected Proximitor sensor, corresponding to the center of the linear measurement range.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan this probe be connected directly to a PLC or DCS analog input card?\u003c\/p\u003e\n\u003cp\u003eNo, this probe requires a 3300 XL Proximitor Sensor to convert its impedance modifications into a modulated -24 VDC voltage output or a 4-20 mA current loop.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes this model include integral armor protection for the extension cable?\u003c\/p\u003e\n\u003cp\u003eNo, the 330703-000-040-10-11-00 variant specifies option 000 for unthreaded length and standard non-armored cable configuration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat target material is used for the factory calibration?\u003c\/p\u003e\n\u003cp\u003eThe sensor system is calibrated at the factory using AISI 4140 steel; other shaft materials will require recalibration due to altered magnetic properties.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIs hot-swapping the probe connection permissible while the monitoring system is powered?\u003c\/p\u003e\n\u003cp\u003eYes, the coaxial connection to the Proximitor can be broken or made while energized without damaging the sensor components, though it will trigger a channel fault alarm.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does moisture affect the coaxial ClickLoc connector junction?\u003c\/p\u003e\n\u003cp\u003eMoisture contamination introduces parallel resistance that skews the gap readings.
