Iyasebenza kwi-Buick LaCrosse GL8 Saab Oyile yoxinzelelo lweSensor 12570798

Ke zeziphi izizathu eziphambili zokukhukuliseka kwe-zero yenzwa yoxinzelelo?

Okokuqala, kukho amaqamza okanye ukungcola kwi-adhesive layer ye-strain gauge.

Okwesibini, igeyiji yoxinzelelo ngokwayo ayizinzanga.

Okwesithathu, kukho i-solder joints kwisekethe.

Okwesine, ukukhululwa koxinzelelo lwe-elastomer akuphelelanga; Ukongeza, inxulumene nentsimi yamagnetic, ukuphindaphinda, ubushushu kunye nezinye izinto ezininzi. Ukuqhutywa kombane okanye ukukhukuliseka okuthile kuya kubakho, kodwa sinokucutha ububanzi bawo okanye siwulungise ngeendlela ezithile.

I-Zero i-thermal drift isalathiso esibalulekileyo esichaphazela ukusebenza kwenzwa yoxinzelelo, kwaye inikwe ingqalelo ngokubanzi. Ngamazwe ngamazwe, kukholelwa ukuba i-zero-point drift thermal drift ixhomekeke kuphela ekungalinganini kunye nokungangqamani kweqondo lobushushu le-resistor-sensitive resistor, kodwa eneneni, i-zero point thermal drift ikwanxulumene nokuvuza okubuyela umva kwesichasi esinovelwano. . Kulo mba, i-polysilicon inokufunxa ukungcola kwentsimbi enzima kwi-substrate, ngaloo ndlela inciphisa ukuvuza okubuyela emva kwe-resistor-sensitive resistor, ukuphucula i-zero-point thermal drift kunye nokuphucula ukusebenza kwenzwa. Zeziphi ezinye iindlela ezikhoyo zokunciphisa kunye nokulungisa ukukhukuliseka kombane?

Ngaphandle kokuchaphazela ukuchaneka komlinganiselo kunye nokunciphisa uvakalelo lwezinzwa zoxinzelelo, zeziphi ezinye iziphumo ezibalulekileyo i-zero drift inazo?

Into ebizwa ngokuba yi-zero drift ibhekisela kwinto yokuba xa igalelo le-amplifier lifutshane-lijikelezwe, kukho i-voltage engaqhelekanga kunye nokutshintsha ngokukhawuleza kwigalelo. Ezona zizathu ziphambili ze-zero drift yimpembelelo yokutshintsha kobushushu kwiiparamitha zetransistor kunye nokuguquguquka kwamandla ombane. Kuninzi lwe-amplifiers, i-zero drift yenqanaba langaphambili inempembelelo enkulu, kwaye izigaba ezininzi kunye nezinto zokukhulisa, kokukhona ubuzaza buba ngu-zero.

Ubungakanani be-drift ikakhulu buxhomekeke ekukhethweni kwezixhobo zoxinzelelo, kwaye isakhiwo okanye ukubunjwa kwezixhobo kugqiba ukuzinza okanye ubushushu bobushushu. Kwakhona kubaluleke kakhulu ukucubungula izinto ezikhethiweyo. Iinkqubo ezahlukeneyo ziya kuvelisa amaxabiso ahlukeneyo oxinzelelo, kwaye isitshixo silele ekuzinzeni kwexabiso lebhulorho okanye utshintsho lomthetho wenkqubo emva kohlengahlengiso oluthile lokuguga.

Zininzi iindlela zokulungisa ukukhukuliseka, eziye zimiselwe ubukhulu becala ziimeko okanye iimfuno zemveliso zabavelisi. Ngoku uninzi lwabavelisi balawula i-zero drift kakuhle kakhulu. Ukulungiswa kweqondo lokushisa kunokuhlawulwa ngokumelana nokushisa kwangaphakathi kunye nokufudumeza ukunganyangeki kwe-zero, ukuguga kunye nokunye.

Kwi-transformer kunye nokuguqulwa kwesiphaluka, i-drift yecandelo lesiphaluka inokuhlawulwa ngokukhetha amacandelo alungileyo kunye nokuyila iisekethe ezifanelekileyo ngakumbi.

Izinto zoxinzelelo kufuneka zibe yinto enovakalelo oluphezulu kunye nokutshintsha kweqondo lokushisa elincinci.
