Isebenza kwiindawo zokumba ze-CAT E330C i-Oil Pressure Sensor 161-1703

Umgaqo osisiseko wetekhnoloji yokudityaniswa kolwazi lwezinzwa ezininzi ufana nje nenkqubo yobuchopho bomntu obucokisekileyo bokusetyenzwa kolwazi, encedisana nokwandisa ulwazi lwezinzwa ezahlukeneyo kumanqanaba amaninzi kunye nendawo eninzi, kwaye ekugqibeleni ivelise ingcaciso engaguqukiyo yokuqwalaselwa. okusingqongileyo. Kule nkqubo, kufuneka sisebenzise ngokupheleleyo idatha yemithombo emininzi yolawulo olunengqiqo kunye nokusetyenziswa, kwaye eyona njongo iphambili yokudityaniswa kolwazi kukufumana ulwazi oluluncedo ngakumbi ngokudityaniswa kolwazi olunamanqanaba amaninzi kunye nolwahlulo olusekwe kulwazi loqwalaselo olwahlukileyo. ifunyenwe nguluvo ngalunye. Oku akuthathi nje kuphela inzuzo yokusebenza ngokubambisana kweenzwa ezininzi, kodwa kwakhona kulandelwa ngokubanzi idatha evela kweminye imithombo yolwazi ukuphucula ubukrelekrele benkqubo yonke yenzwa.

Inzwa yoxinzelelo sesinye sezona zinzwa zisetyenziswa kakhulu. Iinzwa zoxinzelelo zemveli ziyizona zixhobo zomatshini, ezibonisa ukunyanzeliswa kwe-deformation yezinto ezi-elastic, kodwa esi sakhiwo sikhulu ngobukhulu kunye nobunzima obukhulu, kwaye asikwazi ukubonelela ngemveliso yombane. Ngophuhliso lwetekhnoloji ye-semiconductor, izinzwa zoxinzelelo ze-semiconductor zavela. Ibonakaliswa ngumthamo omncinci, ubunzima obulula, ukuchaneka okuphezulu kunye neempawu ezintle zokushisa. Ngokukodwa ngophuhliso lwetekhnoloji ye-MEMS, izinzwa ze-semiconductor ziphuhlisa ngokubhekiselele kwi-miniaturization kunye nokusetyenziswa kwamandla aphantsi kunye nokuthembeka okuphezulu.

Ukusasazwa kwe-silicon yokuhambisa uxinzelelo

Isidluliseli soxinzelelo lwe-silicon esasazekileyo senziwa ngokufaka i-silicon piezoresistive sensor yoxinzelelo kunye nokubekwa yodwa kwiqokobhe lensimbi engenasici. Inokuguqula ulwelo oluzivayo okanye uxinzelelo lwerhasi lube ngumqondiso oqhelekileyo wombane wemveliso yangaphandle. Uluhlu lwe-DATA-52 olusasazekileyo lwe-silicon yokuhambisa uxinzelelo lusetyenziswa ngokubanzi kumlinganiselo wentsimi kunye nolawulo lweenkqubo zemizi-mveliso ezifana nokubonelela ngamanzi / ukuthuthwa kwamanzi, ubushushu, i-petroleum, ishishini lemichiza kunye nesinyithi.
