ʻO ka wehewehe pōkole:

Hana ʻia ʻo MD-FM340 gas mass flow sensor me ka micro-electro-mechanical system (MEMS) flow sensing chips.He kūpono ia no ka nui o ke ana a me ke kaʻina hana maʻemaʻe a maloʻo.Hiki i ka ʻenehana hōkeo kūʻokoʻa ke hiki i ka huahana ke hālāwai me kahi ākea o ke ana kahe, e hōʻoia i ka ʻike kiʻekiʻe, hilinaʻi kiʻekiʻe, kūpaʻa kiʻekiʻe a me ke kumu kūʻai haʻahaʻa.Hoʻokumu ʻia ka FM340 ma luna o ka MEMS flow sensing unit a me ke kiʻekiʻe kiʻekiʻe kiʻekiʻe kikohoʻe kaʻina a me ka calibration circuit (MCU).ʻO ka DELta-sigma A / D converter a me ka logic circuit me ka hana calibration kūloko a me ka mīkini MCU e hōʻoia e hōʻiliʻili maikaʻi ʻia ka hōʻailona sensor i ka manawa maoli e loaʻa ai ka hōʻailona kahe pololei, a ua hoʻokō ʻia ka algorithm uku pili i loko, i ʻole waho waho. koi ʻia ka uku calibration e hōʻoia i ka puka kahe kahe kiʻekiʻe.Hiki ke maʻalahi nā mea hoʻohana e kiʻi i ka ʻikepili ʻikepili pili no ke kamaʻilio;Nui ka laulā o ka noi huahana.
