Gusobanukirwa Ibyiza bya Byuma-Byuma Byohereza

Imiyoboro y'ingutu ningingo zingenzi mubikorwa byinganda bipima ibintu bitari amashanyarazi, nkubushyuhe, umuvuduko, umuvuduko, ninguni. Mubisanzwe, imiyoboro ya 4-20mA ije muburyo butatu: imiyoboro ine (insinga ebyiri zitanga amashanyarazi ninsinga ebyiri zisohoka), imiyoboro itatu-yohereza (ibisohoka nubu amashanyarazi asangira umugozi umwe), hamwe nogukwirakwiza insinga ebyiri.

Muri iki kiganiro, tuzaganira ku byiza byogukwirakwiza insinga ebyiri, ubwoko bwumuvuduko ukabije wamamaye mumyaka yashize. Dore zimwe mu nyungu zingenzi zogukwirakwiza insinga ebyiri:

1. Ntibishobora kwanduzwa na parasitike ya parasitike hamwe nigitonyanga cya voltage: Imashini itanga insinga ebyiri ntishobora kwanduzwa na parasitike ya parasitike hamwe nigitonyanga cyumuvuduko ukabije wicyuma, kibafasha gukoresha insinga zoroshye, zidahenze cyane. Ibi birashobora kuzigama umubare munini wibikoresho byo kwishyiriraho.

2. Kugabanya kwivanga kwa electromagnetic: Iyo imbaraga ziva mumasoko agezweho ari nini bihagije, voltage iterwa numurima wa magneti uhuza umugozi winsinga muri rusange ntagaciro. Ibi ni ukubera ko inkomoko yivanga itera akantu gato gashobora kugabanuka ukoresheje insinga zigoretse.

3. Uburebure bwa kabili ndende: Kwivanga kwa capacitif birashobora gutera amakosa mukurwanya kwakirwa. Nyamara, kuri 4-20mA izengurutswe-insinga ebyiri, kwakirwa kwakirwa mubisanzwe ni 250Ω, bikaba bito bihagije kugirango bitange amakosa adafite akamaro. Ibi bituma uburebure bwa kabili burebure ugereranije na sisitemu ya voltage ya telemetrie.

4. Guhinduka muguhitamo imiyoboro: Ibikoresho bitandukanye byerekana-byerekana cyangwa bifata amajwi birashobora guhindurwa hagati yimiyoboro itandukanye ifite uburebure bwa kabili butandukanye bidateye itandukaniro ryukuri. Ibi bituma habaho kwegereza abaturage amakuru no kugenzura hagati.

5. Kumenya neza amakosa: Gukoresha 4mA kurwego rwa zeru byoroha kumenya imiyoboro ifunguye, imiyoboro migufi, cyangwa ibyangiritse (sensor 0mA).

6. Biroroshye kongeramo ibikoresho byo gukingira byihuta: Ibikoresho byo gukingira birashobora kwongerwaho byoroshye ku cyambu cy’ibisohoka bibiri, bigatuma bigira umutekano kandi birwanya inkuba.

Mugusoza, imiyoboro ibiri itanga insinga zitanga inyungu nyinshi kurenza ubundi bwoko bwikwirakwiza, nko kugabanya kwanduzwa na parasitike ya parasitike ya thermocouples hamwe nigitonyanga cya voltage, kugabanya imiyoboro ya electroniki ya magnetiki, uburebure bwa kabili ndende, guhinduka muguhitamo umuyoboro, gutahura amakosa byoroshye, no kongeramo byoroshye kubaga ibikoresho byo kurinda. Hamwe nizi nyungu, imashini itanga insinga ebyiri ziragenda zikundwa cyane mubikorwa byinganda bisaba gupima neza kandi byizewe.
