Kwezani Kulondola kwa Muyezo: Mvetsetsani Zolakwika Zosatheka, Zachibale, ndi Zolozera

Muzochita zamakina ndi kuyeza kwa mafakitale, kulondola kumafunika. Mawu ngati "± 1% FS" kapena "class 0.5" amapezeka kawirikawiri pazida zosungira zida - koma akutanthauza chiyani? Kumvetsetsa zolakwika zenizeni, zolakwika zachibale, ndi zolakwika (zonse) ndizofunikira posankha zida zoyenera zoyezera ndikuwonetsetsa kulondola kwa ndondomeko.

1. Kulakwitsa Kwambiri: Kodi Kuwerenga Kwanu Kuli Patali Bwanji?

Tanthauzo:

Cholakwika chenicheni ndi kusiyana pakati pa mtengo woyezedwa ndi mtengo weniweni wa kuchuluka. Zimasonyeza kupatuka kwakukulu—kwabwino kapena koipa—pakati pa zimene zaŵerengedwa ndi zimene zili zenizeni.

Fomula:

Chitsanzo:

Ngati kuthamanga kwenikweni kuli 10.00 m³/s, ndipo flowmeter imawerenga 10.01 m³/s kapena 9.99 m³/s, cholakwika chonse ndi ±0.01 m³/s.

2. Cholakwika Chachibale: Kuyeza Zolakwika Zake

Tanthauzo:

Cholakwika chachibale chikuwonetsa cholakwika chonse ngati kuchuluka kwa mtengo woyezedwa, zomwe zimapangitsa kuti zikhale zosavuta kufananiza masikelo osiyanasiyana.

Fomula:

Chitsanzo:

Kulakwitsa kwa 1 kg pa chinthu cha 50 kg kumabweretsa cholakwika cha 2%, kuwonetsa momwe kupatukako kuliri kofunika kwambiri.

3. Vuto Lolozera (Zolakwika Zokwanira): Favorite Metric ya Viwanda

Tanthauzo:

Vuto lolozera, lomwe nthawi zambiri limatchedwa "full-scale error" (FS), ndilo vuto lenileni monga gawo la kuchuluka kwa chida choyezera - osati mtengo woyezedwa. Ndizomwe opanga ma metric amagwiritsa ntchito kuti afotokoze zolondola.

Fomula:

Chitsanzo:

Ngati chiwongola dzanja chili ndi 0-100 bar range ndi ± 2 bar absolute error, cholakwika chake ndi ± 2% FS-popanda kuwerengera kwenikweni.

Chifukwa Chake Kuli Kofunikira: Sankhani Chida Choyenera Molimba Mtima

Ma metrics olakwikawa si ongoyerekeza chabe - amakhudza mwachindunji kuwongolera, kuchuluka kwazinthu, komanso kutsata malamulo. Pakati pawo, cholakwika cholozera ndichomwe chimagwiritsidwa ntchito kwambiri pakugawa zida zolondola.

Malangizo Othandiza: Kusankha mulingo wocheperako pa chida chamitundu ingapo kumachepetsa cholakwika chonse cha %FS kulondola komweko—kuwongolera kulondola.

Yesetsani Miyeso Yanu. Konzani Kulondola Kwanu.

Pomvetsetsa ndi kugwiritsa ntchito malingaliro olakwika atatuwa, mainjiniya ndi akatswiri amatha kusankha zida mwanzeru, kutanthauzira zotulukapo molimba mtima, ndikupanga makina olondola kwambiri pamakina opangira makina ndi kuwongolera.
