Isebenza ku-Buick LaCrosse GL8 Saab Oil Pressure Sensor 12570798

Ngakho-ke yiziphi izizathu eziyinhloko ze-zero drift yenzwa yokucindezela?

Okokuqala, kukhona amabhamuza noma ukungcola ongqimbeni olunamathelayo lwegeji yobunzima.

Okwesibili, i-strain gauge ngokwayo ayizinzile.

Okwesithathu, kukhona amalunga e-solder abonakalayo kusekethe.

Okwesine, ukukhululwa kokucindezeleka kwe-elastomer akuphelele; Ngaphezu kwalokho, ibuye ihlobane nensimu kazibuthe, imvamisa, izinga lokushisa nezinye izinto eziningi. Ukukhukhuleka kukagesi noma ukukhukhuleka okuthile kuzoba khona, kodwa singanciphisa ububanzi bayo noma sikulungise ngezindlela ezithile.

I-Zero thermal drift iyinkomba ebalulekile ethinta ukusebenza kwenzwa yokucindezela, futhi inakekelwe kabanzi. Emazweni ngamazwe, kukholakala ukuthi i-zero point thermal drift incike kuphela ekungalinganini nasekungangeni kwezinga lokushisa kwe-resistor ezwelayo, kodwa empeleni, i-zero point thermal drift nayo ihlobene nokuvuza okubuyela emuva kwesiphikisa esizwela amandla. . Mayelana nalokhu, i-polysilicon ingakwazi ukumunca ukungcola kwensimbi esindayo ku-substrate, ngaleyo ndlela inciphise ukuvuza okubuyela emuva kwe-resistor-sensitive force, ithuthukise i-zero-point thermal drift futhi ithuthukise ukusebenza kwenzwa. Yiziphi ezinye izindlela ezikhona zokunciphisa nokulungisa ukukhukhuleka kukagesi?

Ngaphandle kokuthinta ukunemba kokulinganisa kanye nokunciphisa ukuzwela kwezinzwa zengcindezi, yimiphi eminye imiphumela ebalulekile i-zero drift enayo?

Okubizwa ngokuthi i-zero drift ibhekisela kwinto yokuthi lapho okokufaka kwe-amplifier kufinyezwa isikhashana, kukhona i-voltage engavamile futhi eshintsha kancane kancane kokokufaka. Izizathu eziyinhloko ze-zero drift ithonya lokushintsha kwezinga lokushisa kumapharamitha we-transistor kanye nokuguquguquka kwamandla kagesi. Kuma-amplifiers amaningi, i-zero drift yesigaba sangaphambilini inethonya elikhulu kakhulu, futhi uma izigaba ezengeziwe kanye nezici zokukhulisa, yilapho i-zero drift ibucayi kakhulu.

Ubukhulu bokukhukhuleka buncike kakhulu ekukhethweni kwezinto ezisetshenziswayo, futhi ukwakheka noma ukwakheka kwezinto kunquma ukuzinza noma ukuzwela kwayo ukushisa. Kubaluleke kakhulu futhi ukucubungula izinto ezikhethiwe. Izinqubo ezihlukene zizokhiqiza amanani ahlukene obunzima, futhi ukhiye usekuqinisweni kwevelu yebhuloho noma ukuguqulwa komthetho wenqubo ngemva kokulungiswa okuthile kokuguga.

Kunezindlela eziningi zokulungisa ukukhukhuleka, okunqunywa kakhulu yizimo noma izidingo zokukhiqiza zabakhiqizi. Manje abakhiqizi abaningi balawula i-zero drift kahle kakhulu. Ukulungiswa kwezinga lokushisa kunganxeshezelwa ukumelana nokushisa kwangaphakathi nokushisa ukumelana nokuzwela kwe-zero, ukuguga nokunye.

Ku-transformer enokuguqulwa kwesifunda, ukukhukhuleka kwengxenye yesifunda kunganxeshezelwa ngokukhetha izingxenye ezinhle nokuklama izifunda ezifanele kakhulu.

I-strain material kufanele ibe yinto enokuzwela okuphezulu kanye noshintsho oluncane lokushisa.
