The housing must be secured using the integrated jam nut to prevent vibration-induced signal drift. Precise gap voltage validation is required during installation; the transducer must be positioned to achieve the -10 VDC nominal gap voltage target to ensure the output signal operates within the calibrated linear range. Furthermore, cross-talk suppression must be considered by maintaining adequate distance between multiple probe installations to prevent electromagnetic interference from adjacent oscillators.\u003c\/p\u003e\n\u003ch3\u003e## Ordering info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1x 21000-28-05-15-012-04-02 Probe Housing Assembly\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Lock nut and O-ring assembly\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Technical installation 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\u003eSurface Preparation: Ensure the machine mounting boss is flat and tapped to a depth that permits at least 5 full thread engagements of the NPT mounting thread.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSealing: Apply an industry-approved thread sealant to the NPT threads to prevent lubricant leakage from the internal casing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePositioning: Thread the housing into the mounting boss and adjust axially until the probe tip achieves the required -10 VDC gap voltage relative to the shaft surface.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSecuring: Tighten the jam nut to a torque of 5.1 N-m (45 in-lb) to fix the housing position and prevent mechanical movement during rotation.\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\u003eIs this housing compatible with non-Bently probes?
