Izinzwa zokucindezela ziyingxenye ebalulekile ezimbonini eziningi, ezinikeza ikhono lokulinganisa ngokunembile nangokuthembekile ingcindezi ezinhlelweni ezihlukahlukene.Olunye uhlobo lwenzwa yokucindezela oseluthole ukuduma eminyakeni yamuva nje inzwa yengilazi encibilikayo, eyasungulwa okokuqala yiCalifornia Institute of Technology ngo-1965.
Inzwa yengilazi encibilika kancane ifaka impushana yengilazi enezinga eliphezulu lokushisa efakwe ngemuva kwe-17-4PH ye-low-carbon steel cavity, ne-caticity ngokwayo eyenziwe ngensimbi engagqwali engu-17-4PH.Lo mklamo uvumela ukugcwala kwengcindezi ephezulu kanye nokumelana okusebenzayo nokushaqeka kwengcindezi kungazelelwe.Ukwengeza, ingakwazi ukukala uketshezi oluqukethe inani elincane lokungcola ngaphandle kwesidingo samafutha noma ama-diaphragm okuhlukanisa.Ukwakhiwa kwensimbi engagqwali kuqeda isidingo se-O-rings, ukunciphisa ingozi yokukhishwa kwezingozi zokushisa.Inzwa ingakwazi ukukala kufikela ku-600MPa(6000 bar) ngaphansi kwezimo zengcindezi ephezulu enomkhiqizo wokunemba okuphezulu okuphezulu okungu-0.075%.
Kodwa-ke, ukukala ububanzi obuncane ngenzwa yengilazi encibilika kancane kungaba yinselele, futhi ngokuvamile isetshenziselwa ukulinganisa ububanzi obungaphezulu kuka-500 kPa.Kuzinhlelo zokusebenza lapho i-voltage ephezulu kanye nesilinganiso sokunemba okuphezulu sidingeka, inzwa ingashintsha izinzwa zokucindezela ze-silicon ezisabalalisiwe ngokusebenza kahle nakakhulu.
I-MEMS (Micro-Electro-Mechanical Systems) izinzwa zokucindezela ezisekelwe kubuchwepheshe zingolunye uhlobo lwenzwa oluthole ukuduma eminyakeni yamuva nje.Lezi zinzwa zenziwa kusetshenziswa ama-silicon strain gauge amancane/osayizi we-nanometer, anikeza ukuzwela kokuphuma okuphezulu, ukusebenza okuzinzile, ukukhiqizwa kwenqwaba okuthembekile, nokuphindaphinda okuhle.
Inzwa yengilazi ye-micro-melt isebenzisa ubuchwepheshe obuthuthukisiwe lapho i-silicon strain gauge ifakwa emzimbeni onwebeka wensimbi engenasici engu-17-4PH ngemva kokuba ingilazi incibilike emazingeni okushisa angaphezu kuka-500℃.Lapho i-theelastic bodyundergoescompression deformation, ikhiqiza isignali kagesi ekhuliswa isekethe yokukhulisa isinxephezelo yedijithali nge-microprocessor.Isignali yokuphumayo ibe isingaphansi kwesinxephezelo sokushisa esihlakaniphile kusetshenziswa isofthiwe yedijithali.Ngesikhathi senqubo yokukhiqiza yokuhlanza ejwayelekile, amapharamitha alawulwa ngokuqinile ukugwema ithonya lokushisa, umswakama, nokukhathala komshini.Inzwa ine-ahigh frequency response kanye nebanga lokushisa elibanzi lokusebenza, eliqinisekisa ukuzinza kwesikhathi eside ezindaweni ezinzima zezimboni.
Isekhethi yesinxephezelo sezinga lokushisa ehlakaniphile ihlukanisa izinguquko zezinga lokushisa libe amayunithi amaningana, futhi indawo eyiziro kanye nenani lesinxephezelo seyunithi ngayinye kubhalwa kusekethe yesinxephezelo.Ngesikhathi sokusetshenziswa, lawa manani abhalwa endleleni yokuphuma kwe-analog ethintwa izinga lokushisa, indawo ngayinye yezinga lokushisa ibe "izinga lokushisa lokulinganisa" le-transmitter.Isekhethi yedijithali yenzwa yakhelwe ngokucophelela ukuze isingathe izici ezifana nefrikhwensi, ukuphazamiseka kukazibuthe kagesi, kanye nogesi wokukhuphuka, onekhono eliqinile lokulwa nokuphazamiseka, ububanzi bokunikezwa kwamandla, nokuvikelwa kwe-polarity.
Igumbi lokucindezela lenzwa yengilazi ye-micro-melt lenziwe ngensimbi engagqwali engu-17-4PH engenisiwe, engenawo ama-O-rings, amaweld, noma ukuvuza.Inzwa inamandla okulayisha angaphezu kuka-300% FS kanye nengcindezi yokuhluleka engu-500%FS, okuyenza ilungele izinhlelo zokusebenza ezigcwele ingcindezi ephezulu.Ukuze uvikele ekushayweni kwengcindezi okungazelelwe okungenzeka kumasistimu asebenza ngamanzi, inzwa inomshini wokuvikela owakhelwe ngaphakathi.Isetshenziswa kabanzi ezimbonini ezisindayo ezifana nemishini ye-asengineering, imboni yamathuluzi omshini, i-metallurgy, imboni yamakhemikhali, imboni yamandla, igesi ehlanzekile kakhulu, isilinganiso somfutho we-hydrogen, nemishini yezolimo.
