Wedzera Kurongeka Kwechiyero: Nzwisisa Mhedziso, Hukama, uye Reference Error

Mune otomatiki uye kuyerwa kwemaindasitiri, kunyatsoita zvinhu. Mazwi akaita se "± 1% FS" kana "kirasi 0.5" anowanzoonekwa pamapepa ezviridzwa-asi anorevei chaizvo? Kunzwisisa kukanganisa kwakakwana, kukanganisa kwehama, uye referensi (yakazara) kukanganisa kwakakosha pakusarudza maturusi ekuyera akakodzera uye kuve nechokwadi chekururama kwemaitiro. Gwaro iri rinoparadzanisa zviyero zvezvikanganiso zvakakosha nemienzaniso yakapfava, mazano anoshanda, nyika chaiyo.

1. Mhedziso Kukanganisa: Kure Sei Kuverenga Kwako?

Tsanangudzo:

Mhedziso kukanganisa musiyano pakati pehukoshi hwakayerwa nehukoshi hwechokwadi hwehuwandu. Inoratidza kutsauka kwakajeka-kwakanaka kana kwakashata-pakati pezvinoverengwa uye izvo chaizvo.

Formula:

Muenzaniso:

Kana iyo chaiyo yekuyerera iri 10.00 m³/s, uye flowmeter ichiverenga 10.01 m³/s kana 9.99 m³/s, kukanganisa zvachose i ±0.01 m³/s.

2. Chikanganiso Chehukama: Kuyera Mhosho Yekukanganisa

Tsanangudzo:

Chikanganiso chinoratidza kukanganisa kwakakwana sechikamu chechiyero chakayerwa, zvichiita kuti zvive nyore kuenzanisa pazvikero zvakasiyana.

Formula:

Muenzaniso:

Kukanganisa kwe 1 kg pachinhu che50 kg kunokonzeresa kukanganisa kwe2%, zvichiratidza kuti kutsauka kwakakosha sei mumamiriro ezvinhu.

3. Reference Error (Full-Scale Error): Indasitiri's Favorite Metric

Tsanangudzo:

Reference error, inowanzonzi full-scale error (FS), ndiyo mhosho yakakwana sechikamu chechikamu chechiridzwa chakazara chinoyereka—kwete chete kukosha kwakayerwa. Ndiyo yakajairwa metric vagadziri vanoshandisa kutsanangura chokwadi.

Formula:

Muenzaniso:

Kana geji yekumanikidza ine 0-100 bar range uye ± 2 bar absolute kukanganisa, kukanganisa kwayo kwereferensi ndeye ± 2% FS-yakazvimiririra yekuverenga chaiko kwekumanikidza.

Nei Zvichikosha: Sarudza Chimbo Chakakodzera Neruvimbo

Aya ma metrics ekukanganisa haasi edzidziso chete-anokanganisa zvakananga maitiro ekugadzirisa, kunaka kwechigadzirwa, uye kutevedza kwemitemo. Pakati pavo, chikanganiso chereferenzi ndiyo inonyanya kushandiswa pakurongeka kwezviridzwa.

Pro Tip: Kusarudza mwero wakatetepa pachiridzwa chemhando dzakasiyana-siyana kunoderedza kukanganisa kwakakwana kwe%FS huroyi-kunatsurudza.

Gadzirisa Zviyero Zvako. Gadzirisa Kururama Kwako.

Nekunzwisisa uye nekushandisa aya matatu epfungwa dzekukanganisa, mainjiniya uye matekiniki vanogona kusarudza zviridzwa zvine hungwaru, kududzira mibairo nechivimbo, nekugadzira masisitimu akanyanya muotomatiki uye kutonga nharaunda.
