Iimpawu zoluvo

Isixhobo soluvo sibhekisa kwisixhobo okanye isixhobo esinokuva ubungakanani obuthile bomzimba obuchaziweyo kwaye sisiguqule sibe ngumqondiso osebenzisekayo wokufaka ngokomthetho othile. Ukubeka nje, inzwa sisixhobo esiguqula ubuninzi obungenguwo umbane kubuninzi bombane.

Inzwa idla ngokuba namacandelo amathathu: into enovakalelo, into yokuguqula kunye nesekethe yokulinganisa.

1), into enovakalelo ibhekisa kwindawo enokuva ngokuthe ngqo (okanye ukuphendula) umlinganiselo, oko kukuthi, into enovakalelo elinganiswa ngesixhobo soluvo iguqulelwa kwisixa esingesombane okanye obunye ubungakanani obunobudlelwane obuqinisekileyo. ngomlinganiselo.

2) Into yokuguqula iguqula ubuninzi obungenguwo umbane kwipharamitha yombane.

Isalathiso sophawu lweparameter emileyo yesivamvo

1. Uvakalelo

Uvakalelo lubhekisa kumlinganiselo wemveliso Y kwigalelo X kwimo yoluvo oluzinzileyo, okanye umlinganiselo wokunyuswa kwemveliso Y ukuya kunyuso lwegalelo X, ebonakaliswa ngu k njenge

k=dY/dX

2. Isigqibo

Olona tshintsho luncinci olunokuthi lubonwe sisinzwa ngaphakathi koluhlu oluchaziweyo lokulinganisa lubizwa ngokuba yisisombululo.

3. Uluhlu lokulinganisa kunye noluhlu lokulinganisa

Ngaphakathi komda wemposiso evumelekileyo, uluhlu olusuka kumda osezantsi ukuya kumda ophezulu wexabiso elilinganisiweyo kuthiwa luluhlu lokulinganisa.

4. Umgca womgca (impazamo engekho mgca)

Ngaphantsi kweemeko ezikhankanyiweyo, ipesenti yokuphambuka okukhulu phakathi kwe-sensor calibration curve kunye nomgca ochanekileyo odibeneyo kunye nexabiso elipheleleyo lokuphuma libizwa ngokuba yi-linearity okanye i-nonlinear error.

5. I-Hysteresis

I-Hysteresis ibhekisela kwiqondo lokungahambelani phakathi kweempawu ze-stroke ezintle kunye neempawu ze-stroke eziphambeneyo zenzwa phantsi kweemeko ezifanayo zokusebenza.

6. Ukuphinda-phinda

Ukuphindaphinda kubhekisela ekungahambelani kwesigxina seempawu ezifunyenwe ngokuqhubekayo ngokutshintsha ubuninzi begalelo kwicala elifanayo ngamaxesha amaninzi kulo lonke uluhlu lokulinganisa phantsi kweemeko ezifanayo zokusebenza.

⒎ I-zero drift kunye neqondo lobushushu ukukhukuliseka

Xa i-sensor ingenalo igalelo okanye igalelo lelinye ixabiso, ipesenti yokuphambuka okukhulu kwexabiso legalelo ukusuka kwixabiso lesibonakaliso sokuqala kunye nesikali esipheleleyo yi-zero drift ngamaxesha aqhelekileyo. Nangona kunjalo, kunyuso ngalunye lwe-1℃ kwiqondo lobushushu, ipesenti yophambuko oluphezulu lwexabiso lemveliso yesivamvo ukuya kwisikali esipheleleyo kuthiwa yi-temperature drift.
