Due to the reduced tip size, cross-talk suppression is critical; physical spacing between adjacent 3300 NSv probe tips must be maintained at a minimum of 25 mm to prevent mutual electromagnetic interference. Field calibration requires gap voltage validation utilizing a nominal -10 VDC target midpoint, corresponding to the center of the linear calibration slope. This sensor design captures high-frequency rotor dynamics without physical contact, transmitting instantaneous shaft position data back to the TSI rack.\u003c\/p\u003e\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 Bently Nevada 330901-00-08-10-02-00 Proximity Probe with integral 1.0 meter cable.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 Miniature coaxial male connector protector sheath.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 Technical installation instruction sheet.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Mechanical Constraints\u003c\/h3\u003e\n\u003ch3\u003eMechanical Thread Installation\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eVerify thread matching to 3\/8-24 UNF tapped holes before insertion to prevent cross-threading.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eMaintain a minimum mechanical engagement of 5 full threads within the machine housing block.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eExert a maximum torque value of 3.4 N-m (30 in-lb) when locking the probe positioning nut.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCable Routing Restrictions\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eObserve the minimum bend radius constraint of 25.4 mm (1.0 inch) for the coaxial extension cable lines.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIsolate transducer cables from adjacent high-voltage AC lines to prevent induced signal distortions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEnsure the coaxial connection junction point remains dry, isolated, and housed within an approved terminal enclosure.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Performance FAQ\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eCan this specific probe be deployed without an external Proximitor Sensor module?\u003c\/p\u003e\n\u003cp\u003eNo. This probe is a passive inductive device that requires a 3300 NSv Proximitor Sensor to supply the high-frequency RF signal and demodulate the displacement voltage.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the consequence of exceeding the stated 3.4 N-m torque specification during mounting?\u003c\/p\u003e\n\u003cp\u003eExcessive torque deforms the internal mechanical core assembly of the probe tip, causing permanent calibration shifts or catastrophic internal winding failure.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does a change in the target material from 4140 steel affect the scale factor?\u003c\/p\u003e\n\u003cp\u003eAlternative metals alter the magnetic permeability and electrical conductivity, shifting the factory 7.87 V\/mm scale factor and compromising measurement accuracy.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat occurs if the probe cable is routed parallel to three-phase motor supply leads?\u003c\/p\u003e\n\u003cp\u003eElectromagnetic induction creates high-amplitude noise on the -10 VDC nominal gap voltage, triggering false high-vibration alarms within the monitor rack.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes this model support hot-swapping or disconnects while the monitoring system is live?\u003c\/p\u003e\n\u003cp\u003eYes.
