Technicians must physically space the probe tip from the shaft until a nominal -10 VDC targets output is met at the Proximitor monitor, representing the exact center of the 8 mm tip calibration curve. When multiple proximity probes are mounted within close proximity on the same bearing housing, cross-talk suppression is enforced through structural separation. The probe casings are electrically isolated from the driver circuitry to minimize capacitive interaction and magnetic interference between overlapping radio frequency fields.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is this proximity probe rated for online hot-swap maintenance procedures?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The passive probe assembly can be disconnected from the extension cable or extracted from its housing while the host TSI rack remains powered, without disrupting adjacent monitoring channels.\u003c\/p\u003e\n\u003cp\u003eQ: How does a change in target metallurgy affect the calibrated voltage loop?\u003c\/p\u003e\n\u003cp\u003eA: The system scaling relies on a standard AISI 4140 steel calibration target. Targeting other metals modifies the eddy-current skin depth, which alters the slope from the factory 7.87 V\/mm specification and requires full recalibration.\u003c\/p\u003e\n\u003cp\u003eQ: Can the internal or external probe cables be truncated or lengthened manually?\u003c\/p\u003e\n\u003cp\u003eA: No. The total physical length of the system cable is an intrinsic part of the RF tuning circuit. Any alteration to the cable length shifts the circuit inductance and capacitance, causing severe calibration tracking errors.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRadial Clearance\u003c\/strong\u003e: Maintain a minimum diameter of 30 mm of open space around the probe tip tip to prevent target anomalies from surrounding carbon steel structures.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLocknut Torque Application\u003c\/strong\u003e: Secure the 3\/8-24 UNF threads with the supplied jam nuts to a maximum mechanical torque limit of 11.2 N-m (100 in-lb) to prevent casing distortion.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eConnector Insulation\u003c\/strong\u003e: Protect the miniature coaxial ClickLoc connection point inside the junction box using self-fusing silicone tape or connector protectors to completely block moisture and oil ingress.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eShield Grounding Boundary\u003c\/strong\u003e: The overall cable outer shield must be isolated from the machine ground and connected directly to the dedicated instrument ground point at the 3500 monitor rack terminal block.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSupply Kit Inventory\u003c\/h3\u003e\n\u003cp\u003eEvery standard order fulfillment includes the following baseline items:\u003c\/p\u003e\n\u003cp\u003e(1) Bently Nevada 330101-00-12-10-12-CN Armored Proximity Probe\u003c\/p\u003e\n\u003cp\u003e(2) Set of two hex jam nuts and lockwashers\u003c\/p\u003e\n\u003cp\u003e(3) Removable vinyl thread protectors\u003c\/p\u003e\n\u003cp\u003e(4) Factory-issued material traceability and electrical calibration certificate\u003c\/p\u003e\n\u003ch3\u003eLogistics and Dispatch Criteria\u003c\/h3\u003e\n\u003cp\u003eDelivery time: 2-7 days when payment finish, routed via expedited international carriers such as DHL, FEDEX, or UPS.
