Gas Mass Flowmeter nrog High Precision

Lus piav qhia luv luv:

MD-FM340 gas mass flow sensor yog tsim los ntawm micro-electro-mechanical system (MEMS) flow sensing chips.Nws yog qhov tsim nyog rau ntau hom kev huv thiab cov roj qhuav qhuav ntsuas thiab tswj cov txheej txheem.Lub tshuab ntim khoom tshwj xeeb ua rau cov khoom lag luam kom tau raws li ntau yam kev ntsuas ntws, ua kom muaj kev nkag siab zoo, muaj kev ntseeg siab, ruaj khov thiab tsis tshua muaj nqi.FM340 yog raws li MEMS flow sensing unit thiab high precision digital processing and calibration circuit (MCU).Kev sib koom ua ke DELta-sigma A / D converter thiab cov logic Circuit Court nrog kev ua haujlwm sab hauv calibration thiab MCU processor xyuas kom meej tias lub teeb liab sensor tau sau tau zoo nyob rau lub sijhawm kom tau txais cov teeb liab txaus, thiab cov nyiaj them ua haujlwm raug ua tiav sab hauv, yog li tsis muaj sab nraud. calibration them nyiaj yuav tsum tau los xyuas kom meej siab precision txaus tso zis.Tus phooj ywg digital tso tawm daim ntawv sib txuas lus, cov neeg siv tuaj yeem yooj yim heev kom tau txais cov ntaub ntawv sib txuas lus rau kev sib txuas lus;Cov khoom siv daim ntawv thov yog dav heev.
