Ibyuma byumuvuduko nibintu byingenzi mubikorwa byinshi, bitanga ubushobozi bwo gupima neza kandi byizewe imbaraga mubikorwa bitandukanye.Ubwoko bumwe bwa pression sensorthat bumaze kumenyekana mumyaka yashize ni sensor ya micro-melt sensor, yatunganijwe bwa mbere na Institute of Technology ya Californiya 1965.
Ikirahure cya micro-melt sensor kirimo ifu yikirahure yubushyuhe bwo hejuru yinjijwe inyuma yinyuma ya 17-4PH icyuma gito cya karubone, hamwe na cavite ubwayo ikozwe mubyuma 17-4PH.Igishushanyo cyemerera umuvuduko mwinshi kurenza urugero no guhangana ningutu zitunguranye.Byongeye kandi, irashobora gupima amazi arimo umwanda muke udakeneye amavuta cyangwa diafragma yo kwigunga.Kubaka ibyuma bidafite ingese bikuraho O-impeta, bigabanya ibyago byo kurekura ubushyuhe.Rukuruzi irashobora gupima kugera kuri 600MPa (6000 bar) mugihe cyumuvuduko mwinshi hamwe nibicuruzwa ntarengwa-0.075%.
Nyamara, gupima intera ntoya hamwe nikirahure micro-melt sensor irashobora kugorana, kandi mubisanzwe ikoreshwa mugupima intera iri hejuru ya 500 kPa.Mubisabwa aho voltage nini hamwe nibipimo bisobanutse neza, sensor irashobora gusimbuza ibyuma bya silikoni gakondo ikwirakwizwa hamwe nubushobozi bukomeye.
MEMS (Micro-Electro-Mechanical Sisitemu) ikoranabuhanga rishingiye ku ikoranabuhanga ni ubundi bwoko bwa sensor imaze kumenyekana mu myaka yashize.Izi sensororo zakozwe hifashishijwe micro / nanometero-nini ya silicon yerekana ibipimo, bitanga umusaruro mwinshi, imikorere ihamye, umusaruro wizewe, hamwe nibisubirwamo neza.
Ikirahure cya micro-melt sensor ikoresha ikoranabuhanga ryateye imbere aho igipimo cya silicon cyapimwe kumubiri wa 17-4PH ibyuma bitagira umuyonga nyuma yikirahure kimaze gushonga mubushyuhe buri hejuru ya 500 ℃.Iyo theelastic bodyundergoescompression deformasiyo, itanga ibimenyetso byamashanyarazi byongerwaho numuyoboro wogukwirakwiza digitale hamwe na microprocessor.Ibisohoka bisohoka noneho birashobora kwishyurwa ubushyuhe bwubwenge ukoresheje software.Mugihe cyibikorwa bisanzwe byo kweza, ibipimo bigenzurwa cyane kugirango birinde ingaruka zubushyuhe, ubushuhe, numunaniro wa mashini.Rukuruzi rufite ahigh inshuro nyinshi hamwe nubushyuhe bwagutse bwo gukora, byemeza ko igihe kirekire gihamye mubidukikije bikaze.
Ubwenge bwubushyuhe bwubwenge bugabanya impinduka zubushyuhe mubice byinshi, kandi umwanya wa zeru nagaciro kindishyi kuri buri gice byanditswe mumuzunguruko.Mugihe cyo gukoresha, izo ndangagaciro zanditswe muburyo busa n’ibisohoka byatewe nubushyuhe, hamwe na buri kintu cyubushyuhe kikaba "Calibration temperature" ya transmitter.Inzira ya sisitemu ya sensor yakozwe muburyo bwitondewe kugirango ikemure ibintu nkinshuro, kwivanga kwa electromagnetique, hamwe na voltage ya surge, hamwe nubushobozi bukomeye bwo kurwanya interineti, amashanyarazi yagutse, hamwe no kurinda polarite.
Icyumba cyumuvuduko wikirahure micro-melt sensor ikozwe mubyuma bitumizwa mu mahanga 17-4PH, bitagira O-impeta, gusudira, cyangwa kumeneka.Rukuruzi ifite ubushobozi bwa anoverload ya 300% FS hamwe na afailure yumuvuduko wa 500% FS, bigatuma iba nziza kubisabwa byumuvuduko mwinshi.Kugirango wirinde ihungabana ritunguranye rishobora kugaragara muri sisitemu ya hydraulic, sensor ifite ibikoresho byubatswe birinda.Ikoreshwa cyane mu nganda ziremereye nk'imashini zikora imashini, inganda zikoresha imashini, metallurgie, inganda z’imiti, inganda z’amashanyarazi, gazi isukuye cyane, gupima ingufu za hydrogène, n’imashini z’ubuhinzi.
