Kulawulo oluzenzekelayo lwenkqubo yokulinganisa, inzwa yoxinzelelo iyafuneka ukuba ivakale ngokuchanekileyo umqondiso womxhuzulane.Kwaye unempendulo engcono eguqukayo kunye nokusebenza okungcono kokuchasana nokuphazamiseka.Isiginali ebonelelwe yinzwa yoxinzelelo ingabonakaliswa ngokuthe ngqo, irekhodwe, iprintwe, igcinwe okanye isetyenziswe ekulawuleni impendulo yenkqubo yokufumanisa.Ukuhlanganiswa kwenzwa yoxinzelelo kunye nesekethe yokulinganisa kunciphisa kakhulu ubukhulu besixhobo.Ukongeza, uphuhliso lwetekhnoloji yokukhusela luya kuphucula isakhono sokuchasana nokuphazamiseka kunye nenqanaba lolawulo oluzenzekelayo lokulinganisa inzwa yoxinzelelo.

2. Izinzwa zoxinzelelo kwishishini lepetrochemical

Inzwa yoxinzelelo yenye yezona zixhobo zokulinganisa ezisetyenziswa kakhulu kulawulo lwe-petrochemical automation.Kwiiprojekthi ezinkulu zeekhemikhali, phantse zonke izicelo zezivamvo zoxinzelelo zigutyungelwe: uxinzelelo oluhlukileyo, uxinzelelo olupheleleyo, uxinzelelo lwegeyiji, uxinzelelo oluphezulu, uxinzelelo oluhlukileyo, ubushushu obuphezulu, ubushushu obuphantsi, i-remote ye-flange sensors yezixhobo ezahlukeneyo kunye nokulungiswa okukhethekileyo.

Imfuno yezinzwa zoxinzelelo kwishishini lepetrochemical igxile ikakhulu kwimiba emithathu: ukuthembeka, ukuzinza kunye nokuchaneka okuphezulu.Phakathi kwabo, ukuthembeka kunye neemfuneko ezininzi ezongezelelweyo, ezifana nomlinganiselo womgama kunye nohlobo lwebhasi, kuxhomekeke kuyilo lwesakhiwo, inqanaba leteknoloji yokucubungula kunye nezakhiwo ze-transmitter.Ukuzinza kunye nokuchaneka okuphezulu kwe-pressure transmitter kuqinisekiswa ikakhulu ngokuzinza kunye nokulinganisa ukuchaneka kwenzwa yoxinzelelo.

Ukuchaneka komlinganiselo kunye nesantya sokuphendula senzwa yoxinzelelo luhambelana nokuchaneka komlinganiselo we-pressure transmitter.Iqondo lokushisa kunye neempawu zoxinzelelo lwe-static kunye nokuzinza kwexesha elide le-sensor yoxinzelelo luhambelana nokuzinza kwe-transmitter yoxinzelelo.Imfuno yeenzwa zoxinzelelo kwi-petrochemical industry ibonakaliswe kwimiba emine: ukuchaneka kokulinganisa, ukuphendula ngokukhawuleza, iimpawu zeqondo lokushisa kunye neempawu zoxinzelelo lwe-static, kunye nokuzinza kwexesha elide.

3. Inzwa yoxinzelelo kunyango lwamanzi

Ishishini lokucocwa kwamanzi lokukhuselwa kwendalo liphuhliswe ngokukhawuleza kwiminyaka yakutshanje kwaye linamathuba abanzi.Kumanzi kunye nonyango lwamanzi amdaka, iinzwa zoxinzelelo zibonelela ngolawulo oluphambili kunye nokubeka iliso ekukhuseleni inkqubo kunye nokuqinisekiswa komgangatho.Inzwa yoxinzelelo iguqula uxinzelelo (ngokuqhelekileyo uxinzelelo lwamanzi okanye igesi) ibe ngumqondiso wombane wokuphuma.Iimpawu zoxinzelelo zombane zingasetyenziselwa ukulinganisa inqanaba lolwelo lolwelo olungatshintshiyo, ngoko ke lunokusetyenziselwa ukulinganisa inqanaba lolwelo.Into yokuva i-sensor yoxinzelelo ikakhulu yenziwe yi-silicon cup sensing element, i-oyile ye-silicone, i-diaphragm yodwa kunye ne-air duct.Uxinzelelo lomlinganiselo ophakathi lugqithiselwa kwicala le-silicon cup element ngokusebenzisa i-diaphragm yodwa kunye neoli ye-silicone.Uxinzelelo lwereferensi ye-atmospheric lusebenza kwelinye icala lento ye-silicon yekomityi ngombhobho womoya.Ikomityi yeSilicon yikomityi emile njenge-monocrystalline silicon wafer kunye nomzantsi obhityileyo.Ngaphantsi kwesenzo soxinzelelo, i-diaphragm esezantsi kwendebe i-elastically deformed kunye nokuhamba okuncinci.I-silicon ye-Monocrystalline yi-elastomer efanelekileyo.I-deformation ihambelana ngokungqongqo noxinzelelo, kwaye ukusebenza kokubuyisela kuhle kakhulu.

4. Izinzwa zoxinzelelo kwishishini lezonyango

Ngokuphuhliswa kweemarike zezixhobo zonyango, iimfuno eziphezulu zibekwe phambili ukuze kusetyenziswe izinzwa zoxinzelelo kwishishini lezonyango, njengokuchaneka, ukuthembeka, ukuzinza kunye nomthamo.Inzwa yoxinzelelo inesicelo esilungileyo kwi-catheter ablation encinci kunye nomlinganiselo wesivamvo sobushushu.

I-5.MEMS inzwa yoxinzelelo

Inzwa yoxinzelelo lwe-MEMS luhlobo oluthile lwefilimu ebhityileyo, eya kuthi ikhubazeke xa iphantsi koxinzelelo.I-Strain gauges (i-piezoresistive sensing) ingasetyenziselwa ukulinganisa le deformation, kunye ne-capacitive sensing ingasetyenziselwa ukulinganisa utshintsho kumgama phakathi kweendawo ezimbini.
