The probe does not include integrated lead armor on its unarmored cable, making it ideal for standard conduit layouts or configurations where space and flexibility are critical. Operating in tandem with a matching 7200 series Proximitor, this probe converts physical displacement into a continuous, linear voltage signal directly proportional to the relative motion of the target surface.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 mm tip diameter\u003c\/strong\u003e providing stable eddy-current target area excitation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/8-24 reverse thread configuration\u003c\/strong\u003e tailored for specific internal and non-standard mechanical installations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.0-meter integrated cable length\u003c\/strong\u003e providing proper reach to intermediate junction boxes or extension cables.\u003c\/li\u003e\n\u003cli\u003eFitted with a \u003cstrong\u003eminiature male coaxial connector\u003c\/strong\u003e for low-loss signal transfers.\u003c\/li\u003e\n\u003cli\u003eBuilt without structural lead armor to maximize flexibility during complex cable routing routing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRadial shaft vibration monitoring\u003c\/li\u003e\n\u003cli\u003eAxial thrust position measurements\u003c\/li\u003e\n\u003cli\u003eEccentricity and shaft orbital analysis\u003c\/li\u003e\n\u003cli\u003eSpeed and phase reference tracking (Keyphasor)\u003c\/li\u003e\n\u003cli\u003eHeavy rotating machinery diagnostics (turbines, compressors, and gearboxes)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cp\u003eThe following ordering matrix breakdown is extracted directly from official technical datasheets for the \u003cstrong\u003e7200 5 mm and 8 mm Standard Mount Probe\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e7200-21508-02-12:\u003c\/strong\u003e Construction Case reference option designating an 8 mm probe tip diameter, reverse configuration type, and 3\/8-24 threads without lead armor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10:\u003c\/strong\u003e Cable Length Option designating 1.0 meter (39 inches).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e02:\u003c\/strong\u003e Connector Option designating a miniature male coaxial connector configuration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003eBrand\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003eBently Nevada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003e\u003cstrong\u003eModel \/ Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003ePart Number\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003e7200-21508-02-12-10-02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"4\"\u003e\u003cstrong\u003eMechanical Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003eProbe Tip Diameter\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003e8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003e\u0026amp;
