Ngaphezu kwe- "Temperature Drift", inzwa enengqondo ephezulu idinga ukuphenya okungaphezulu kwalokho, futhi ukungahambi kahle kungenye yezinkomba zokusebenza okubalulekile.
Kungani kufanele ukhathazeke ngokungeyona imibala yezinzwa zokucindezela? Inzwa yengcindezi iyingxenye esemqoka ye-Transmitter yengcindezelo. Okwamanje, okuvame ukusetshenziswainzwa yokucindezelaIngabe inzwa ye-Piezoresoresistive Pressure, kanti isiginali yayo yokuphuma inokungalingani okukhulu, okuzothinta ngokuqondile ukunemba kokusebenza nokulinganisa kokudluliselwa kwengcindezi.
Ngakho-ke yini ukungahambi kahle kwenzwa? Ngencazelo, ukungahambi kahle kwenzwa kusho ukuthi ingcindezi iyashintsha, umphumela we-sensor yengcindezi iveza ijika lesici. Amaphesenti aphakathi kokuphambuka okuphezulu kwale Curve kanye nomugqa ofanele kanye nokukhishwa okugcwele kwenzwa kubizwa ngokuthi ukungazinzi. Ubukhulu baleli phesenti bunquma ukungahambi kahle kwenzwa. Ngokuqonda okulula futhi okunembile, kusho ukuthi izinga lokuphambuka phakathi kwejika lokuphuma kanye nomugqa oqondile ofanelekile angajwayelekile.
Kungani izinzwa zengcindezi zinezinkinga ezingezinhle? I-Piezeresistive Pressure Sensor esetshenziswa ngokujwayelekile kwebhuloho (Whistn Bridge), njengoba kukhonjisiwe kwisibalo esingezansi,
Esimweni sokuqala, amanani okumelana nezingalo ezine zebhulodi zihlala zinjalo. Lapho amandla angaphandle wokufaka enza, isimo esilinganiselwe sokwehluka kwengalo yebhuloho sizophulwa. Ngalesi sikhathi, umehluko ongaba khona uzovela endaweni yokugcina. Ukushintshwa okulinganiselwe kwebhuloho le-ARM ukumelana kusengxenye ethile, futhi ukushintshwa okulinganiselwe kwebhuloho lokumelana nokumelana kunquma ukungahambi kahle kwenzwa.
Futhi inzwa ngayinye ye-PieZoresistive Pressure yamukela ezinye izinqubo ezikhethekile enqubweni yokukhiqiza, njengokuguga, ukuthuthuka kwengcindezi, ukushiswa, njll. Ngaphezu kwalokho, kwinqubo yangempela yokukhiqiza ye-chip ye-silicon esetshenzisiwe, 4 Kunzima ukugcina inani lokumelana le-bridge ngayinye livumelana ngokuphelele, ngakho-ke inzwa ngayinye inomuzwa wokungakhethi.
Njengoba ukungahambi kahle kubaluleke kakhulu, kanjani ukubala inani elingabonakali lenzwa? Okokuqala, vumela inzwa incishise inzwa yengcindezi ngaphansi kwendawo yokushisa ebekiwe, yengeze ku-zero ibe yisilinganiso esigcwele, inciphise ingcindezi ngemuva kwengcindezi. Ngemuva kwalokho, ebangeni eliphelele kufaka phakathi imikhawulo ephezulu nephansi yokulinganisa inzwa, khetha amaphuzu angu-6 kuya kwayi-11 asatshalaliswe ngokulinganayo ukuze uhlolwe, bese uphinda isivivinyo sokukhuphuka kanye nokuwa kokuvuka kwe-Clission Times ezintathu noma ngaphezulu.
