Ngenxa yenqanaba elingalinganiyo lenzwa yoxinzelelo lwemoto kwimarike ngoku, sikhetha njani kwaye sichonge umsebenzi kunye nomgangatho wenzwa yoxinzelelo lwemoto?Makhe sithethe malunga neeparamitha zokusebenza zenzwa yoxinzelelo njengoko kungezantsi:
Isivamvo soxinzelelo sibhekisa kwisixhobo esinokuva uxinzelelo kwaye siguqule utshintsho loxinzelelo kwimveliso yombane.Lolona hlobo luqhelekileyo lwenzwa kwisixhobo esizenzekelayo, kunye nenkqubo ye-nervous kwisixhobo sokulinganisa amandla okuzenzekelayo.Ukusetyenziswa okuchanekileyo kwenzwa yoxinzelelo kufuneka kuqala kuqonde iiparamitha zoxinzelelo lwemoto.
eyona parameters ye Autopressure sensors ngolu hlobo lulandelayo:
1, Umthwalo wokukala isivamvo uxinzelelo: Iyunithi jikelele Bar, Mpa, njl Ukuba uluhlu lokulinganisa yi 10Bar, uluhlu lokulinganisa loluvo yi 0-10 bar 0-1.Mpa.
I-2, Uluhlu lweqondo lokushisa olusebenzayo lubhekiselele kuluhlu lweqondo lokushisa apho iiparamitha zokusebenza zenzwa yoxinzelelo zingasetyenziswa ngaphandle kweenguqu ezinobungozi ezisisigxina.
3, Uluhlu lwembuyekezo yobushushu : ukuba kolu luhlu lobushushu, isiphumo esilinganisiweyo kunye nebhalansi ye-zero yenzwa ibuyekezwe ngokungqongqo, ukuze ingagqithi kuluhlu oluchaziweyo.
I-4, ifuthe lobushushu kwi-zero: Impembelelo yeqondo elingu-zero ibhekiselele kwimpembelelo yokutshintsha kweqondo lobushushu kwindawo engu-zero yesivamvo soxinzelelo.Ngokubanzi, ichazwa njengepesenti yotshintsho lwe-zero equilibrium olubangelwa yi-10℃ nganye utshintsho lobushushu kwimveliso ekalisiweyo, kwaye iyunithi ithi: %FS/10℃.
5, ubuntununtunu Iqondo lobushushu isiphumo ngaphandle: Uvakalelo lobushushu drift ibhekisa kutshintsho ubuntununtunu inzwa yoxinzelelo olubangelwa utshintsho lobushushu ambient.Ngokubanzi, ibonakaliswa njengepesenti yesiphumo esilinganisiweyo sokutshintsha kobuntununtunu okubangelwa kukutshintsha kobushushu be-10℃, kwaye iyunithi yile: FS/10℃.
I-6, isiphumo esilinganisiweyo: i-coefficient ye-signal ye-coefficient ye-sensor yoxinzelelo, iyunithi yi-mV / V, i-1mV / V eqhelekileyo, i-2mV / V, imveliso epheleleyo ye-sensor yoxinzelelo = i-voltage yokusebenza * ubuntununtunu, umzekelo: I-voltage esebenzayo 5VDC, uvakalelo 2mV / V, uluhlu olupheleleyo oluphumayo ngu-5V * 2mV / V = 10mV, njenge-sensor yoxinzelelo olupheleleyo olupheleleyo lwe-10Bar, uxinzelelo olupheleleyo lwe-10Bar, imveliso yi-10mV, uxinzelelo lwe-5Bar yi-5mV.
7, Umda oKhuselekileyo womthwalo: Umda womthwalo okhuselekileyo uthetha ukuba awuyi kubangela umonakalo owonakalisayo kwinzwa yoxinzelelo ngaphakathi kwalo mthwalo, kodwa awukwazi ukulayishwa ixesha elide.
I-8: Ukugqithiswa okuphezulu: kubhekiselele kumda wexabiso lomthwalo wenzwa yoxinzelelo.
9. Ukungahambelani: Umgca ubhekiselele kwipesenti yokutenxa okukhulu phakathi komgca womgca kunye nomlinganiselo wegophe lokunyuka komthwalo ngokuchasene nesiphumo esilinganisiweyo, esinqunywe ngexabiso lemveliso yomthwalo ongenanto kunye nomthwalo olinganisiweyo.Kwithiyori, isiphumo senzwa kufuneka sibe ngumgca.Enyanisweni, akunjalo.I-nonlinearity yipesenti yokutenxa kokufanelekileyo.Iyunithi engangqamananga yile: %FS, imposiso engaqhelekanga = uluhlu * olungenamgca, ukuba uluhlu luyi-10Bar kwaye i-nonlinear yi-1%fs, impazamo engabonakaliyo yile: 10Bar*1%=0.1Bar.
I-11: Ukuphindaphinda: impazamo ibhekiselele ekulayisheni ngokuphindaphindiweyo kwenzwa kumthwalo olinganisiweyo kunye nokukhulula phantsi kweemeko ezifanayo zokusingqongileyo.Ipesenti yomahluko omkhulu phakathi kwexabiso lemveliso kunye nesiphumo esilinganisiweyo kwindawo yomthwalo ofanayo ngexesha lokulayisha.
I-12: I-Hysteresis: ibhekiselele ekulayisheni ngokuthe ngcembe kwenzwa yoxinzelelo ukusuka kungabikho mthwalo ukuya kumthwalo olinganisiweyo kunye nokukhulula ngokuthe ngcembe.Umahluko omkhulu phakathi kweziphumo ezilayishiweyo nezingalayishwanga kwindawo enye yomthwalo njengepesenti yesiphumo esilinganisiweyo.
I-13: I-voltage excitation: ibhekiselele kumbane osebenzayo we-sensor yoxinzelelo, ngokubanzi i-5-24VDC.
I-14: Ukumelana nokufaka: kubhekiselele kwixabiso lokuchasana elilinganiswa ukusuka ekupheleni kwegalelo lenzwa yoxinzelelo (imigca ebomvu kunye nemnyama yeenzwa zoxinzelelo lwemoto) xa isiphelo sesiphumo somqondiso sivulekile kwaye inzwa ayicinezeleki.
I-15: Ukuchasana kwemveliso: kubhekiselele ekuchaseni okulinganiswa kwimveliso yesignali xa igalelo lenzwa yoxinzelelo lifutshane kwaye inzwa ayinyanzeliswa.
I-16: I-impedance ye-insulation: ibhekisela kwixabiso le-DC impedance phakathi kwesiphaluka senzwa yoxinzelelo kunye ne-elastomer.
I-17: I-Creep : ibhekisela kwipesenti yenguqu kwisiphumo senzwa yoxinzelelo ngexesha elide ukuya kwisiphumo esilinganisiweyo, esiqhelekileyo se-30min, phantsi komqathango wokuba umthwalo uhlala ungatshintshi kwaye ezinye iimeko zokuvavanya zihlala zingatshintshi.
I-18: ibhalansi ye-zero: Ixabiso lemveliso ye-sensor yoxinzelelo njengepesenti yesiphumo esilinganisiweyo kwi-excitation yombane ekhuthazwayo xa uthululwa.Kwithiyori, imveliso yenzwa yoxinzelelo kufuneka ibe zero xa ikhutshiwe.Enyanisweni, imveliso yenzwa yoxinzelelo ayikho zero xa ikhutshwe.Kukho ukutenxa, kwaye imveliso yero yipesenti yokutenxa.
Oku ngasentla kukujongwa ngokubanzi kweeparameters zenzwa yoxinzelelo lwemoto.Ukuba unalo naliphi na icebiso, nceda uzive ukhululekile ukushiya uluvo, Umzi-mveliso wethu woxinzelelo loxinzelelo ujonge phambili ekusekeni ubudlelwane obuzinzileyo kunye nexesha elide lwentsebenziswano nangaliphi na ixesha.
