Maintaining precise physical alignment and correct system matched capacitance ensures linear eddy-current probe scaling across the 200 mV\/mil output response curve. Field setup requires static gap voltage validation (-10 VDC baseline setting target) using a calibrated digital multimeter during probe positioning. Correct gap setting prevents signal saturation at high vibration amplitudes and optimizes cross-talk suppression between adjacent vertical and horizontal shaft channels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the 21500-00-16-05-02 probe connect directly to a 3500 series monitor card?\u003c\/p\u003e\n\u003cp\u003eA: No, the proximity probe must route through an appropriately matched 7200 Series Proximitor sensor and extension cable to convert field capacitance change into a proportional voltage signal.\u003c\/p\u003e\n\u003cp\u003eQ: Can the integral 0.5-meter probe cable be cut or modified during installation?\u003c\/p\u003e\n\u003cp\u003eA: No, trimming or splicing the probe cable changes total circuit inductance and capacitance, causing severe calibration error in probe scaling.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the 1\/4-28 UNF probe body threads and tip area for dirt, metal shavings, or mechanical thread damage before mounting.\u003c\/li\u003e\n\u003cli\u003eThread the probe into the machine casing tapping boss until the probe tip approaches the target shaft face.\u003c\/li\u003e\n\u003cli\u003eSupply power to the associated Proximitor sensor and monitor the DC gap voltage across the sensor signal terminals.\u003c\/li\u003e\n\u003cli\u003eAdjust the probe position mechanically until the gap voltage reaches the nominal -10 VDC gap target (approximate midpoint of the 200 mV\/mil linear range).\u003c\/li\u003e\n\u003cli\u003eLock the probe securely in place using a external locknut, torque to standard mechanical limits, and route the integral cable to the extension cable junction box.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":53211180597557,"sku":"21500-00-16-05-02","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/30000-00-08-18-02_055f8515-bea6-43d2-b318-e8458ffb207b.png?v=1784862356","url":"https:\/\/www.5gplc.com\/products\/21500-00-16-05-02-bently-nevada-7200-series-proximity-probes","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
