Sonke siyazi ukuba eyona nto iphambili yesikali sombane yiiseli yomthwalo, ebizwa ngokuba "yintliziyo" ye-elektronikiisikali. Kunokuthiwa ukuchaneka kunye novakalelo lwenzwa lumisela ngokuthe ngqo ukusebenza kwesikali sombane. Ngoko ke sikhetha njani iseli yomthwalo? Kubasebenzisi bethu abaqhelekileyo, iiparameters ezininzi zeseli yomthwalo (ezifana nokungahambelani, i-hysteresis, i-creep, uluhlu lwembuyekezo yeqondo lokushisa, ukuchasana kwe-insulation, njl.) ngokwenene kusenza sigqithise. Makhe sijonge kwiimpawu zoluvo lwesikali sombane malunga teyona parameters zobugcisa.
(1) Umthwalo olinganiselweyo: ubukhulu bomthwalo we-axial onokuthi inzwa inokulinganisa ngaphakathi koluhlu lwesalathisi sobugcisa obuchaziweyo. Kodwa ekusetyenzisweni okwenyani, ngokubanzi kuphela i-2/3 ~ 1/3 yoluhlu olulinganisiweyo lusetyenziswa.
(2) Umthwalo ovumelekileyo (okanye ukulayisha ngokukhuselekileyo): ubuninzi be-axial umthwalo ovunyelwe yiseli yomthwalo. Ukusebenza ngokugqithisileyo kuvunyelwe phakathi koluhlu oluthile. Ngokubanzi 120% ~ 150%.
(3) Umthwalo wokukhawulela (okanye umda wokukhawulela): umthwalo ophezulu we-axial onokuthwala inzwa yesikali sombane ngaphandle kokwenza ukuba ilahlekelwe amandla ayo okusebenza. Oku kuthetha ukuba inzwa iya konakala xa umsebenzi udlula eli xabiso.
(4) Uvakalelo: Umlinganiselo wokunyuswa kwemveliso ukuya kumthwalo osetyenziswayo. Ngokuqhelekileyo i-mV yesiphumo esilinganisiweyo nge-1V yegalelo.
(5) I-Nonlinearity: Le yiparameter ebonisa ukuchaneka kobudlelwane obuhambelanayo phakathi kwemveliso yesignali yombane nge-sensor yesikali sombane kunye nomthwalo.
(6) Ukuphindaphinda: Ukuphindaphinda kubonisa ukuba ixabiso lemveliso yenzwa inokuphinda iphindwe kwaye ihambelane xa umthwalo ofanayo usetyenziswa ngokuphindaphindiweyo phantsi kweemeko ezifanayo. Olu phawu lubaluleke ngakumbi kwaye lunokubonisa ngcono umgangatho wenzwa. Inkcazo yempazamo yokuphindaphinda kumgangatho wesizwe: impazamo yokuphindaphinda inokulinganiswa kunye nokungahambelani ngexesha elifanayo njengomahluko omkhulu (mv) phakathi kwamaxabiso omqondiso wesiphumo esilinganiswa kathathu kwindawo yovavanyo olufanayo.
(7) Lag: Intsingiselo edumileyo ye-hysteresis kukuba: xa umthwalo usetyenziswa inyathelo ngesinyathelo kwaye emva koko uthulwe ngokulandelelana, ngokuhambelana nomthwalo ngamnye, ngokufanelekileyo kufuneka kubekho ukufundwa okufanayo, kodwa ngokwenene kuyahambelana, iqondo lokungahambelani. ibalwa ngempazamo ye-hysteresis. isalathisi sokumela. Impazamo ye-hysteresis ibalwa kumgangatho wesizwe ngolu hlobo lulandelayo: umahluko omkhulu (mv) phakathi kwe-arithmetic mean yelona xabiso lophawu oluphumayo lwemivumbo emithathu kunye ne-arithmetic mean yelona xabiso lophawu lwemveliso lweziphumo ezithathu kuvavanyo olufanayo. inqaku.
(8) I-Creep kunye ne-creep recovery: Impazamo ye-creep ye-sensor iyadingeka ukuba ihlolwe kwiinkalo ezimbini: enye i-creep: umthwalo olinganisiweyo usetyenziswa ngaphandle kwempembelelo ye-5-10 imizuzwana, kunye ne-5-10 imizuzwana emva kokulayisha.. Thatha ufundo, emva koko urekhode amaxabiso emveliso ngokulandelelana ngamaxesha aqhelekileyo kwithuba lemizuzu engama-30. Okwesibini ukubuyiswa kwe-creep: susa umthwalo olinganisiweyo ngokukhawuleza (ngaphakathi kwe-5-10 imizuzwana), ufunde ngokukhawuleza kwimizuzwana emi-5-10 emva kokukhulula, kwaye urekhode ixabiso lemveliso ngexesha elithile kwimizuzu engama-30.
(9) Ubushushu obuvumelekileyo bokusetyenziswa: buchaza amaxesha afanelekileyo kule seli yomthwalo. Umzekelo, inzwa yobushushu obuqhelekileyo iphawulwe njenge: -20℃- +70℃. Abenzi boluvo bobushushu obuphezulu baphawulwe ngolu hlobo: -40°C - 250°C.
(10) Uluhlu lwembuyekezo yeqondo lokushisa: Oku kubonisa ukuba inzwa ihlawulwe ngaphakathi kwinqanaba lobushushu ngexesha lokuvelisa. Umzekelo, iisensi zobushushu eziqhelekileyo ziphawulwa njenge -10°C - +55°C.
(11) Ukuxhatshazwa kwe-insulation: ixabiso lokumelana ne-insulation phakathi kwecandelo lesekethe ye-sensor kunye ne-elastic beam, inkulu ngakumbi, ubungakanani bokumelana nokukhusela kuya kuchaphazela ukusebenza kwenzwa. Xa ukuchasana kwe-insulation kuphantsi kunexabiso elithile, ibhuloho ayiyi kusebenza ngokufanelekileyo.
