Njengengxenye ebalulekile yeingcindezi transmitter, inzwa inezinkomba ezintathu ezibalulekile ezinganquma ukuthi ukudluliselwa kwengcindezelo kungakwenza yini umsebenzi wokulinganisa kahle, yilezi: ingcindezi ye-hysteresis, ukuphindaphindwa kwengcindezi kanye nokuqina.
Ukudluliselwa ngakunye kufanele kuhlolwe futhi kulungiswe lapho kushiya ifektri ukuyenza ihlangabezane namazinga athile, kanti eminye imisebenzi kumele yenziwe kahle lapho inzwa iphuma efektri, futhi ingcindezi i-hytentesis ingenye yazo.
Yini ingcindezi i-hysteresis?
Ngesikhathi senqubo yokulinganisa yengcindezelo yokudlulisa, ingcindezi ihlolwe nge-diaphragm yodwa kanye ne-tube yokucindezela - ukufuya. Yize ubuningi bokufaka buzobukwa, ukuqondisa nosayizi wokulayisha ingcindezi nokulayisha kwengcindezi yokudlulisela kwimibandela yangempela yokusebenza umehluko kuzoholela kumasayizi ahlukene wokukhishwa kwesiginali kagesi. Ukuphathwa kabi kwama-curve aphumayo okufakwayo kuma-stres aphambili futhi ahlehlise ukubuyela emuva kuyingcindezi hysteresis.
Izici ezithinta ingcindezi hysteresis?
Okokuqala, ake sibheke izingxenye zenzwa ye-silicon yokucindezela ye-silicon!
I-Silicon Pressure Sensor yakhiwa nge-chip ye-silicon ye-silicon, isisekelo sensimbi, ikhava ye-ceramic insulating, i-silicon uwolati, i-siaphragm, njll. Lapho ingcindezi isebenza kwi-sensor yengcindezi, izinto ezinjenge-chinesi zizoshintshana ngamadigri ahlukahlukene. Lapho ingcindezi isuswa, ukuguquguquka kuzonyamalala.
Kodwa-ke, noma ngabe kungabuyiselwa esimweni sokuqala kuncike kwizici zezinto ezibonakalayo uqobo, kanye nendlela yokucubungula, imvelo nezinye izinto. Ngakho-ke, noma ngabe iphuzu elifanayo lokucindezela lifaka, okuphumayo ngeke kuhambisane nemivimbo edlulile nangokubuyela emuva.
Ungabala kanjani ingcindezi i-hysteresis?
Ubukhulu bephutha le-hysteresis ngokuvamile bunqunywa yindlela yokuhlola. Ngaphansi kwamaphoyinti wokucindezela wokulinganisa okuningi ngaphakathi kwebanga lokucindezela, qhathanisa umehluko phakathi kwezilinganiso ezihlekisayo nezingalungile zokukhipha izinhlaka zamaphoyinti wokulinganisa wengcindezi, inani eliphelele lomehluko wesilinganiso esiphezulu kanye nephesenti lesilinganiso esigcwele. Kuyiphutha le-hysteresis, futhi iphutha le-hysteresis libizwa nangokuthi iphutha lokubuya.
Endaweni yokushisa ebekiwe, ingcindezi yenzwa ehlolwe iphakanyiswe emkhawulweni ophezulu wesilinganiso, futhi ingcindezi incishisiwe ngemuva kokuqina kwengcindezi, bese ibuyela endaweni ye-zero. Iphuzu lokuhlola, phinda amahlandla amathathu noma amathathu ukukhulisa futhi wehlise umjikelezo wokulinganisa,
Ungakwenza Kanjani Ukwandisa Ingcindezi Hysteresis?
I-chip-Phezulu i-Sienzicon Piezoresoresive Pressure Tress, ngokusebenzisa othomathikhi we-Chip Bonding Equipment, ukubopha okuphelele kwe-Chip, kuqinisekiswe ukusebenza kwenqubo ekhethekile ye-diaphragm yedwa, kuqinisekiswe ukusebenza kwenqubo ekhethekile kunciphisa ingcindezi yezinzwa ngezinzwa zokuguga kanye nokuthuthuka kwengcindezi.
