Mismatched probes will yield incorrect output and void safety compliance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow can I diagnose a \"Not OK\" condition remotely?\u003c\/strong\u003e\u003cbr\u003eMonitor the 4-20 mA loop current; if it drops below 3.6 mA, the transmitter has detected a fault in the probe, extension cable, or internal circuitry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the probe gap critical for accuracy?\u003c\/strong\u003e\u003cbr\u003eAbsolutely. If the gap is outside the 0.5-1.75 mm range, the transmitter's linear response is compromised, and the output signal will not represent the true vibration amplitude.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSelection Tip: How do I choose between different system lengths?\u003c\/strong\u003e\u003cbr\u003eThe system length must match your probe-to-transmitter cable run. Incorrect cable lengths introduce signal attenuation, which negatively impacts the calibration of the 4-20 mA output.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/990_Graphs_and_Figures.png?v=1775026312\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45013981233334,"sku":"990-05-70-02-00","price":115.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/BentlyNevada990_3_de5b668c-d84c-486b-886f-bc7c504caa4a.jpg?v=1781084528","url":"https:\/\/www.plcsparehub.com\/products\/bently-nevada-990-05-70-02-00-vibration-transmitter-0-5-mils-range","provider":"Global PLC Spare Hub","version":"1.0","type":"link"}
