During the setup phase, gap voltage validation is performed to achieve a -10 VDC target at the mid-point of the linear operating range. This ensures the signal swing is centered within the input range of the monitor module. Technicians must prioritize cross-talk suppression by maintaining adequate separation between probe tips, which prevents the excitation fields of adjacent sensors from distorting phase-angle and amplitude measurements.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) 330902-00-40-10-02-CN Proximity Probe\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTwo (2) 3\/8-24 UNF-2A hex locknuts\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOne (1) silicone connector protector sleeve\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCompliance and factory calibration documentation\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\u003eMounting Engagement\u003c\/strong\u003e: Ensure a minimum of five (5) full thread turns are engaged within the mounting bracket to secure the probe position under vibration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eGap Setting\u003c\/strong\u003e: Verify the static gap using a feeler gauge to ensure the probe tip does not contact the shaft during thermal expansion or mechanical deflection.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCable Management\u003c\/strong\u003e: Secure the coaxial lead to a static structural member at frequent intervals to minimize cable whip and prevent connector strain.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eShield Grounding\u003c\/strong\u003e: Ground the coaxial shield at only one point—the monitor rack terminal—to prevent ground loops that introduce noise into the signal chain.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDelivery Information\u003c\/h2\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eDelivery time: 2-7 days when payment finish.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDispatched via DHL\/FEDEX\/UPS.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAnti-static industrial packaging used to ensure protection against impact and electrostatic discharge.\u003c\/p\u003e\n\u003c\/li\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\u003e\u003cstrong\u003eCan the 330902 probe be used with standard 3300 XL Proximitors?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The NSv probe is designed specifically for the 3300 NSv Proximitor sensor due to different carrier frequencies and impedance characteristics.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the consequence of exceeding the 1.5 mm linear range?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eExceeding the range causes the signal to deviate from the linear slope, leading to distorted vibration waveforms and inaccurate amplitude measurement.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIs this probe suitable for submerged oil service?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, provided the coaxial connector is protected by the silicone sleeve to prevent conductive fluids from bridging the connector pins and causing signal attenuation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the probe output voltage increase with distance?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe probe uses an inductive oscillator; as the target moves away, the loading on the coil decreases, shifting the output voltage closer to the supply voltage (-24 VDC).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCan the probe cable be shortened in the field?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Altering the cable length changes the impedance of the tuned circuit, which invalidates the factory calibration and significantly degrades measurement accuracy.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHow is probe health monitored in the 3500 system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe monitor constantly checks the gap voltage.
