Izinzwa zoxinzelelo ziyinxalenye ebalulekileyo kumashishini amaninzi, ukunika amandla okulinganisa ngokuchanekileyo nangokuthembekileyo uxinzelelo kwizicelo ezahlukeneyo. Olunye uhlobo lwenzwa yoxinzelelo oluye lwafumana ukuthandwa kule minyaka yamva nje yiglasi yokunyibilika kweglasi, eyathi yaphuhliswa okokuqala yiCalifornia Institute of Technology ngo-1965.
Isivamvo seglasi esinyibilikayo sinobushushu obuphezulu beglasi obungumgubo ofakwe ngasemva kwentsimbi yentsimbi eyi-17-4PH ephantsi, kunye nomngxuma ngokwawo owenziwe ngentsimbi ye-17-4PH. Olu yilo luvumela ukugqithiswa koxinzelelo oluphezulu kunye nokuchasana okusebenzayo kwiintshukumo zoxinzelelo ngequbuliso. Ukongeza, inokulinganisa ulwelo oluqulethe ukungcola okuncinci ngaphandle kwesidingo seoyile okanye i-diaphragms yodwa. Ukwakhiwa kwensimbi engenasici kuphelisa isidingo se-O-rings, ukunciphisa umngcipheko wokukhutshwa kweengozi zokushisa. Inzwa inokulinganisa ukuya kuthi ga kwi-600MPa (i-6000 bar) phantsi kweemeko zoxinzelelo oluphezulu kunye nemveliso ephezulu echanekileyo ye-0.075%.
Nangona kunjalo, ukulinganisa amanqanaba amancinci ngeglasi ye-micro-melt sensor kunokuba ngumngeni, kwaye isetyenziselwa kuphela ukulinganisa uluhlu olungaphezulu kwe-500 kPa. Kwizicelo apho i-voltage ephezulu kunye nomlinganiselo ophezulu wokuchaneka uyimfuneko, i-sensor inokutshintsha izinzwa zoxinzelelo ze-silicon ezisasazekileyo ngokusebenza ngakumbi.
I-MEMS (i-Micro-Electro-Mechanical Systems) i-teknoloji-based based sensor sensors yolunye uhlobo lwenzwa oluye lwafumana ukuthandwa kwiminyaka yamuva. Ezi zivamvo zenziwe kusetyenziswa i-micro/nanometer-ubungakanani be-silicon strain gauges, ebonelela ngovelwano oluphezulu lwemveliso, ukusebenza okuzinzileyo, ukuveliswa kwebhetshi ethembekileyo, kunye nokuphindaphinda okulungileyo.
Isivamvo seglasi esinyibilikayo seglasi sisebenzisa itekhnoloji ephucukileyo apho i-silicon strain gauge ifakwa kwi-17-4PH yentsimbi engenasici emzimbeni emva kokuba iglasi inyibilika kumaqondo obushushu angaphezu kwe-500 ℃. Xa i-theelastic bodyundergoescompression deformation, ivelisa umqondiso wombane okhuliswa yisekethe yokukhulisa imbuyekezo yedijithali ngemicroprocessor. Umqondiso wemveliso uxhomekeke kwimbuyekezo yobushushu obukrelekrele usebenzisa isoftware yedijithali. Ngexesha lenkqubo yemveliso yokucoca, iiparamitha zilawulwa ngokungqongqo ukunqanda impembelelo yobushushu, ukufuma, kunye nokudinwa koomatshini. I-sensor ine-ahigh frequency response kunye noluhlu olubanzi lobushushu bokusebenza, ukuqinisekisa ukuzinza kwexesha elide kwiindawo ezinzima zoshishino.
Isekethe yembuyekezo yobushushu obukrelekrele yahlula utshintsho lobushushu kwiiyunithi ezininzi, kwaye indawo ye-zero kunye nexabiso lembuyekezo yeyunithi nganye ibhalwe kwisekethe yembuyekezo. Ngethuba lokusetyenziswa, ezi xabiso zibhalwa kwindlela yokuphuma kwe-analog echaphazelekayo yiqondo lokushisa, kunye neqondo lokushisa ngalinye "liqondo lokushisa lokulinganisa" lomthumeli. Isekethe yedijithali ye-sensor yenzelwe ngononophelo ukuphatha izinto ezinje ngokuphindaphindiweyo, ukuphazamiseka kwe-electromagnetic, kunye ne-voltage yokunyuka, enekhono elinamandla lokuchasana nokuphazamiseka, uluhlu olubanzi lonikezelo lwamandla, kunye nokhuseleko lwe-polarity.
Igumbi loxinzelelo lweglasi ye-micro-melt sensor yenziwe ngaphandle kwe-17-4PH yensimbi engenasici, ngaphandle kwe-O-rings, i-welds, okanye ukuvuza. Isivamvo sinomthwalo ongaphezulu we-300% FS kunye noxinzelelo lokusilela lwe-500% FS, iyenza ilungele usetyenziso loxinzelelo oluphezulu. Ukukhusela ukutshatyalaliswa ngokukhawuleza koxinzelelo olunokuthi lwenzeke kwiinkqubo ze-hydraulic, inzwa inesixhobo sokukhusela esakhelwe ngaphakathi. Isetyenziswa kakhulu kumashishini anzima anje ngoomatshini be-asengineering, ishishini lezixhobo zoomatshini, isinyithi, ishishini lemichiza, ishishini lamandla, igesi ecocekileyo, umlinganiselo woxinzelelo lwe-hydrogen, kunye noomatshini bezolimo.
