با سلام و سپاس از اساتید گرامی که برای پاسخ به سوالات وقت میزارن

در کارت AI8x12 bit اگر برای 4 تا 20 میلی آمپر بکار بره چقدر تغییر در جریان را حس می کنه مثلا آیا یکصدم میلی آمپر تغییر در جریان را می تونه سنس کنه ؟

اگر کارت 16 بیتی باشه تغییرات چقدره ؟

ممنون

با سلام

فرمول بدست آوردن مقدار تغییرات (البته به صورت تقریبی) به این صورت است :

حد بالای سیگنال ورودی به کارت - حد پایین سیگنال ورودی به کارت / 2 به توان Resolution کارت

در کارت 16 بیتی لازم است 2 به توان 15 برسد زیرا یک بیت برای علامت است.

با این فرمول برای 4 تا 20 میلی آمپر در کارت 12 بیتی مقدار3.90 میلی آمپر تغییر در کارت سنس می شود و در کارت 16 بیتی مقدار برابر 0.48 میلی آمپر می باشد.
