Yandisa ukuchaneka koMlinganiso: Qonda impazamo eQelekileyo, eSihlobo, kunye neReferensi
Kwi-automation kunye ne-industrial measurement, ukuchaneka kubalulekile. Imigaqo efana ne "± 1% FS" okanye "iklasi ye-0.5" ibonakala rhoqo kwiinkcukacha zedatha yesixhobo-kodwa zithetha ukuthini ngokwenene? Ukuqonda impazamo epheleleyo, impazamo ehambelanayo, kunye nempazamo yereferensi (epheleleyo) kubalulekile ekukhetheni izixhobo ezifanelekileyo zokulinganisa kunye nokuqinisekisa ukuchaneka kwenkqubo. Esi sikhokelo sichitha ezi mitha zeemposiso eziphambili ngemizekelo elula, iifomthi ezilula kunye neengcebiso ezisebenzayo.
1. Imposiso epheleleyo: Kukude kangakanani ukufunda kwakho?
Ingcaciso:
Impazamo epheleleyo ngumahluko phakathi kwexabiso elilinganisiweyo kunye nexabiso lokwenyani lomyinge. Ibonakalisa ukutenxa okukrwada—okulungileyo okanye okubi—phakathi koko kufundiweyo noko kuyinyani.
Ifomula:
Imposiso epheleleyo = Ixabiso eliMngqiniweyo − Ixabiso lokwenyani
Umzekelo:
Ukuba elona qondo lokuqukuqela yi-10.00 m³/s, kunye ne-flowmeter ifundeka ngo-10.01 m³/s okanye 9.99 m³/s, impazamo epheleleyo ngu-±0.01 m³/s.
2. Impazamo enxulumeneyo: Ukulinganisa iMpembelelo yemposiso
Ingcaciso:
Impazamo enxulumeneyo ibonisa imposiso epheleleyo njengepesenti yexabiso elilinganisiweyo, ikwenza kube lula ukuthelekisa kwizikali ezahlukeneyo.
Ifomula:
Impazamo enxulumeneyo (%) = (Imposiso epheleleyo / iXabiso eliMediweyo) × 100
Umzekelo:
Impazamo ye-1 kg kwinto ye-50 kg ikhokelela kwimpazamo ye-2%, ebonisa ukuba kubaluleke kangakanani ukutenxa kumxholo.
3. Imposiso yeReferensi (Impazamo yesikali esiPheleleyo): IMetric eyiFavorite yeShishini
Ingcaciso:
Impazamo yereferensi, edla ngokubizwa ngokuba yimpazamo yesikali esipheleleyo (FS), yimpazamo epheleleyo njengepesenti yoluhlu olunokumetwa olupheleleyo lwesixhobo—hayi nje ixabiso elilinganisiweyo. Yimilinganiselo esetyenziswa ngabavelisi bemetriki ukuchaza ukuchaneka.
Ifomula:
Imposiso yeSingqinisiso (%) = (Imposiso epheleleyo / Uluhlu olupheleleyo lwesikali) × 100
Umzekelo:
Ukuba i-gauge ye-pressure gauge inoluhlu lwe-bar ye-0-100 kunye ne-± 2 ibha epheleleyo yephutha, impazamo yayo yereferensi yi-± 2% FS-ezimeleyo yokufundwa koxinzelelo lwangempela.
Kutheni Kubalulekile: Khetha iSixhobo esiLungileyo ngokuzithemba
Ezi metrics zempazamo azikho ithiyori kuphela-zichaphazela ngokuthe ngqo ulawulo lwenkqubo, umgangatho wemveliso, kunye nokuthotyelwa kwemithetho. Phakathi kwazo, impazamo yereferensi yeyona isetyenziswa kakhulu kuhlelo lokuchaneka kwesixhobo.
Ingcebiso yePro: Ukukhetha uluhlu olumxinwa lomlinganiselo kwisixhobo soluhlu oluninzi kunciphisa imposiso epheleleyo yale %FS ichanekileyo-ukuphucula ukuchaneka.
Yiphathe kakuhle imilinganiselo yakho. Lungiselela Ukuchaneka Kwakho.
Ngokuqonda nokusebenzisa ezi ngqikelelo zintathu zeempazamo, iinjineli kunye neengcali zinokukhetha izixhobo ngobulumko ngakumbi, zitolike iziphumo ngokuzithemba ngakumbi, kwaye ziyile iinkqubo ezichanekileyo ngakumbi kwi-automation kunye nokulawula imekobume.
