This 100% brand new, factory-original package pairs a robust 14 mm industrial probe with a matched signal converter to track shaft displacement, rotational speed, and gear tooth passage in demanding turbomachinery setups. The integrated system delivers the rapid transient response times and high-frequency capabilities mandatory for machinery protection networks, overspeed trip systems, and predictive maintenance protocols following strict API 670 industry standards.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003eThe system architecture separates physical data collection from signal conversion to preserve measurement integrity.

You must align the sensing tip parallel with the rotational path of the gear teeth. Keep the air gap within the specified 1.0 mm or 1.5 mm boundary relative to your specific gear tooth size to prevent pulse dropouts.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Epro","offers":[{"title":"Default Title","offer_id":43880519958627,"sku":"PR9376\/010-011+CON021","price":350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/5246\/8067\/files\/94_30749e45-3c4c-41e0-aea2-6173cc358f0d.jpg?v=1765270191","url":"https:\/\/www.autocontrolglobal.com\/products\/emerson-epro-speed-sensor-pr9376-010-011-con021","provider":"AutoControl Global","version":"1.0","type":"link"}
