Standard 5mm or 8mm probes require a large clear area around the tip to prevent side-loading, where adjacent metal parts corrupt the reading. The NSv ignores surrounding counterbore walls down to very small diameters, making it ideal for tight spaces where a standard probe would experience massive electrical cross-talk or offset saturation.\u003c\/p\u003e\n\u003ch3\u003eQ2: Can I connect this 0.5-meter probe directly to a 9-meter extension cable?\u003c\/h3\u003e\n\u003cp\u003eNo, the total electrical length of the system must match the calibration profile of the Proximitor sensor. A 0.5-meter probe requires a 4.5-meter extension cable to match a 5.0-meter Proximitor, or an 8.5-meter extension cable to pair with a 9.0-meter Proximitor. Mixing mismatched probe and cable lengths alters system impedance, destroying the 200 mV\/mil scale factor accuracy.\u003c\/p\u003e\n\u003ch3\u003eQ3: What is the primary sign that a reverse-mount probe has suffered internal mechanical damage?\u003c\/h3\u003e\n\u003cp\u003eA continuous open circuit or an immediate shift to a supply rail voltage (typically near -24 Vdc) at the Proximitor output indicates a broken center conductor within the probe or cable. If the gap voltage remains static regardless of physical distance adjustments during installation, the probe tip has likely shorted against the internal housing or experienced structural damage from contact with the shaft target.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518907048109,"sku":"330906-02-12-10-02-00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330906-02-12-10-02-00-3300-nsv-reverse-mount-probe-3v1sqxdrdml.jpg?v=1766981294","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-330906-02-12-10-02-00-3300-nsv-reverse-mount-proximity-probe","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
