Field alignment requires formal gap voltage validation (-10 VDC targets) at the Proximitor output terminal to orient the probe tip within the center of its 160 mil calibration envelope. This precise physical position enables appropriate resolution for tracking dynamic rotor dynamics under high velocity or varying thermal conditions. To safeguard processing performance, cross-talk suppression is maintained by respecting the minimum structural separation guidelines between nearby sensors measuring orthogonal vibration coordinates.\u003c\/p\u003e\n\u003ch3\u003eShipping Inventory\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 330703-000-070-10-02-00 Proximity Probe with 1.0 m integrated coaxial lead wire\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2 3\/8-24 UNF Hexagonal Locking Nuts\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 Pre-installed ClickLoc Coaxial Connector Protector Sleeve\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 Product Field Reference Document\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\u003eMechanical Thread Engagement and Torque Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eGuide the probe housing into the 3\/8-24 UNF receiving bore, guaranteeing at least 5 full threads of engagement for robust mounting stability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAdjust the probe to target distance using electrical multimeter tracking, then lock the jam nuts to a terminal torque limit of 10.7 N-m (95 in-lb).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCoaxial Wire Path and Shielding Rules\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eLay out the flexible coaxial line while maintaining a minimum bend radius of 25.4 mm (1.0 in) to prevent internal transmission failures.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIsolation of the sensor wire must be maintained inside grounded metal conduit lines to bypass induced electrical noise from high-voltage cables.\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 baseline gap voltage is demanded during field commissioning?\u003c\/p\u003e\n\u003cp\u003eThe hardware must be mechanically adjusted to register a baseline value of -10 VDC targets from the Proximitor loop, which matches the true linear center of the sensor tip.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan this specific proximity probe operate without an external Proximitor?\u003c\/p\u003e\n\u003cp\u003eNo, this component is a passive induction element and must be integrated with a 3300 XL Proximitor Sensor to convert the signal into a linear output voltage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes this model configuration include built-in flexible stainless steel conduit armor?\u003c\/p\u003e\n\u003cp\u003eNo, the 330703-000-070-10-02-00 variant indicates a standard coaxial cable wire configuration without the optional external stainless steel protective armor sheath.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWill altering the length of the integrated cable modify measurement accuracy?\u003c\/p\u003e\n\u003cp\u003eYes, cutting or extending the integral lead wire modifies the impedance tuning properties of the sensor loop, which degrades the output scale factor accuracy.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat standard metallic target alloy is used to factory-calibrate the 11mm tip?\u003c\/p\u003e\n\u003cp\u003eThe primary scale factor tracking is calibrated against AISI 4140 steel targets;
