Sonke siyazi ukuba eyona nto iphambili kwisikali se-elektronikiiseli yokulayisha, ebizwa ngokuba "yintliziyo" yesixhobo se-elektronikiisikaliKunokuthiwa ukuchaneka kunye novakalelo lwesensor kumisela ngokuthe ngqo ukusebenza kwesikali se-elektroniki. Ngoko ke sikhetha njani iseli yomthwalo? Kubasebenzisi bethu ngokubanzi, iiparameter ezininzi zeseli yomthwalo (ezifana nokungangqamani, i-hysteresis, i-creep, uluhlu lokuhlawula ubushushu, ukumelana nobushushu, njl.njl.) zisenza sixineke ngokwenene. Makhe sijonge iimpawu zesensor yesikali se-elektroniki. malunga no-tiiparameter eziphambili zobugcisa.
(1) Umthwalo olinganisiweyo: umthwalo ophezulu we-axial onokulinganiswa yi-sensor ngaphakathi koluhlu oluchaziweyo lwesalathisi sobugcisa. Kodwa xa usetyenziswa ngokwenene, kusetyenziswa kuphela i-2/3 ~ 1/3 yoluhlu olulinganisiweyo.
(2) Umthwalo ovumelekileyo (okanye ukulayisha ngaphezulu okukhuselekileyo): umthwalo ophezulu we-axial ovunyelwe yiseli yomthwalo. Ukusebenza ngokugqithisileyo kuvunyelwe ngaphakathi koluhlu oluthile. Ngokubanzi yi-120% ~ 150%.
(3) Umthwalo olinganiselweyo (okanye umlinganiselo womthwalo ogqithisileyo): umthwalo ophezulu we-axial onokuthwalwa yi-sensor yesikali se-elektroniki ngaphandle kokuyenza ilahlekelwe bubuchule bayo bokusebenza. Oku kuthetha ukuba i-sensor iya konakala xa umsebenzi udlula eli xabiso.
(4) Uvakalelo: Umlinganiselo wokunyuka kwemveliso kukunyuka komthwalo osetyenzisiweyo. Ngokwesiqhelo i-mV yemveliso elinganisiweyo nge-1V yegalelo.
(5) Ukungangqamani: Le yiparameter ebonisa ukuchaneka kobudlelwane obuhambelanayo phakathi kokuphuma kwesignali yevolthi yi-sensor yesikali se-elektroniki kunye nomthwalo.
(6) Ukuphindaphinda: Ukuphindaphinda kubonisa ukuba ixabiso lemveliso ye-sensor linokuphindwa kwaye lihambelana na xa umthwalo ofanayo usetyenziswa ngokuphindaphindiweyo phantsi kweemeko ezifanayo. Olu phawu lubaluleke ngakumbi kwaye lunokubonakalisa ngcono umgangatho we-sensor. Inkcazo yempazamo yokuphindaphinda kumgangatho wesizwe: impazamo yokuphindaphinda inokulinganiswa ngokungangqamani ngexesha elifanayo nomahluko omkhulu (mv) phakathi kwamaxabiso esibonakaliso sokukhupha esilinganiswe kathathu kwindawo yovavanyo efanayo.
(7) Ukulibaziseka: Intsingiselo edumileyo ye-hysteresis yile: xa umthwalo usetyenziswa inyathelo ngenyathelo uze ukhululwe ngokulandelelana, uhambelana nomthwalo ngamnye, ngokufanelekileyo kufuneka kubekho ukufundwa okufanayo, kodwa eneneni kuyahambelana, inqanaba lokungangqinelani libalwa ngempazamo ye-hysteresis. Isalathisi sokumela. Impazamo ye-hysteresis ibalwa kumgangatho wesizwe ngolu hlobo lulandelayo: umahluko omkhulu (mv) phakathi kwentsingiselo ye-arithmetic yexabiso lesignali yomphumo yokwenyani yemivumbo emithathu kunye nentsingiselo ye-arithmetic yexabiso lesignali yomphumo yokwenyani yemivumbo emithathu kwindawo yovavanyo efanayo.
(8) Ukubuyiselwa kwe-creep kunye ne-creep: Impazamo ye-creep ye-sensor kufuneka ihlolwe kwiinkalo ezimbini: enye yi-creep: umthwalo olinganisiweyo usetyenziswa ngaphandle kwempembelelo imizuzwana emi-5-10, kunye nemizuzwana emi-5-10 emva kokulayisha.. Bala izinto ozifundileyo, uze ubhale phantsi ixabiso leziphumo ngokulandelelana ngamaxesha athile kwisithuba semizuzu engama-30. Eyesibini kukubuyisela amandla: susa umthwalo olinganisiweyo ngokukhawuleza (kwimizuzwana emi-5-10), funda ngoko nangoko kwimizuzwana emi-5-10 emva kokukhulula, uze urekhode ixabiso lemveliso ngamaxesha athile kwimizuzu engama-30.
(9) Ubushushu obuvumelekileyo bokusetyenziswa: buchaza amaxesha afanelekileyo ale seli yomthwalo. Umzekelo, isenzi sobushushu esiqhelekileyo sihlala siphawulwa ngolu hlobo: -20℃- +70℃Izinzwa zobushushu obuphezulu ziphawulwe ngolu hlobo: -40°C - 250°C.
(10) Uluhlu lwembuyekezo yobushushu: Oku kubonisa ukuba isensa ihlawulwe ngaphakathi kolu luhlu lobushushu ngexesha lokuveliswa. Umzekelo, iisensa zobushushu eziqhelekileyo zihlala ziphawulwa njenge--10°C - +55°C.
(11) Ukumelana nokufakwa kwe-insulation: ixabiso lokumelana nokufakwa kwe-insulation phakathi kwenxalenye yesekethe ye-sensor kunye nomqadi we-elastic, kokukhona inkulu, ubukhulu bokumelana nokufakwa kwe-insulation buya kuchaphazela ukusebenza kwe-sensor. Xa ukumelana nokufakwa kwe-insulation kuphantsi kunexabiso elithile, ibhulorho ayizukusebenza kakuhle.
