Successful field implementation requires precise gap voltage validation, where the static gap is adjusted to hit -10 VDC targets at the center of the probe linear range. This electrical baseline is mandatory for the 3500 monitoring platform to calculate absolute vibration without waveform clipping. Furthermore, practitioners must employ effective cross-talk suppression by ensuring adequate physical spacing between multiple probes mounted on the same bearing plane, preventing interference from overlapping electromagnetic fields.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent Content\u003c\/strong\u003e: One (1) 330101-00-08-20-02-CN proximity probe.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Hardware\u003c\/strong\u003e: Two (2) 3\/8-24 UNF hex locknuts for mechanical depth adjustment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Kit\u003c\/strong\u003e: One (1) silicone connector protector to maintain signal integrity in oil-mist environments.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation \u0026amp; Wiring Guide\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Mounting\u003c\/strong\u003e: Ensure a minimum of five (5) full thread turns are engaged within the mounting bracket to guarantee structural stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Clearance\u003c\/strong\u003e: Perform a physical gap check during installation to confirm that rotor expansion will not result in contact between the shaft and the probe tip.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding Protocol\u003c\/strong\u003e: Terminate the coaxial shield only at the Proximitor sensor housing terminal block to maintain a clean single-point ground.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Routing\u003c\/strong\u003e: Route the integral coaxial cable through static, vibration-isolated conduits to mitigate mechanical fatigue and cable whip.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eLogistics \u0026amp; Delivery\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelivery time\u003c\/strong\u003e: 2-7 days when payment finish.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipping\u003c\/strong\u003e: Dispatched globally via DHL, FEDEX, or UPS.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging\u003c\/strong\u003e: Each unit is secured in professional anti-static industrial packaging with shock-absorbing foam to prevent transit damage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical FAQ\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the consequence of probe tip contact during operation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePhysical contact typically causes catastrophic failure of the internal induction coil, resulting in an open circuit that the Proximitor detects as a NOT OK status (near 0 VDC output).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCan this 2.0 meter probe be used with 5.0 meter extension cables?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the 3300 XL system is designed for a fixed total length of either 5.0 or 9.0 meters.
