The 31000 series housing allows for precise axial adjustment of the probe tip, facilitating the -10 VDC gap voltage validation required for linear output. Rotor dynamics analysis is highly sensitive to mounting-induced vibration; therefore, the housing must be secured to the machine casing using the included jam nut to prevent mechanical drift. Cross-talk suppression is achieved by observing minimum spacing requirements when multiple housings are mounted in close proximity on the same axial plane.\u003c\/p\u003e\n\u003ch3\u003eOrdering info\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1x 31000-27-05-00-035-03-02 Probe Housing Assembly\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Jam nut\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x O-ring seal kit\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1x Installation technical manual\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\u003eMachining: Prepare the machine mounting boss with a hole tapped perpendicular to the shaft centerline to prevent angular measurement errors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSealing: Apply thread sealant compatible with process lubricants to the NPT threads before installation into the machine case.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eLocking: After the probe gap is set to the nominal -10 VDC target, tighten the jam nut to 5.1 N-m (45 in-lb) to ensure structural stability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eInspection: Verify the integrity of the O-ring seal during each maintenance interval to prevent lubricant leakage from the machine casing.\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 standard 8 mm probes?
