1.Ibyuma byubushyuhe bwa PT100zisanzwe zikoreshwa zifatanije nibikoresho byerekana, ibikoresho byo gufata amajwi, kubara hakoreshejwe ikoranabuhanga, nibindi. Gupima neza ubushyuhe bwamazi, amavuta na gaze hamwe nubuso bukomeye hagati ya -200 ° C ~ 500 ° C mubikorwa bitandukanye.Kugirango umenye niba ari byiza cyangwa bibi, koresha gusa multimeter kugirango ubipime.
2. Ikiranga ubushyuhe bwa PT100 ni uko ibyasohotse bibiri bisohoka (rimwe na rimwe byinshi-bitumanaho) bihujwe na multimeter (nubwo hari agaciro kanini ko guhangana).Niba uruzinduko rufunguye ruzaba rubi, nta gushidikanya ko ari intambwe yambere mu rubanza nyirizina.Agaciro ko guhangana nubushyuhe bwumuriro burashizweho.Kurugero, ubushyuhe busanzwe bwa PT100 buri hafi 110 oms, naho ubushyuhe busanzwe bwa CU50 ni 55 oms.Ibisohoka bya thermocouple nigiciro cya voltage.Ku bushyuhe runaka, izasohoka ibimenyetso bya voltage muri rusange bike kugeza kuri mirongo ya milivolts, bishobora gupimwa na voltage ya dosiye ya multimeter.
3. Ibisohoka voltage ya thermocouple ni mV nkeya, ukurikije ukuri kwa multimeter.Multimeter ya digitale irashobora gukoreshwa mugupima no guca imanza.Ibisohoka bya thermocouple biri murutonde rwa milivolts.Ntabwo bishoboka kumenya ibisohoka hamwe na multimeter, ariko birashobora gupimwa kubikomeza.Mu bihe byinshi, mugihe cyose igice cya galvanic (aho insinga zombi zasudiwe) gihujwe, nta okiside, nta byangiritse, kandi muri rusange ntakibazo.Mugihe kimwe rero, irashobora gukurwa mumashuka kugirango igenzurwe neza.Kugenzura rwose, birakenewe gukoresha thermocouple isanzwe yo kugereranya no gupima milivolt agaciro isohoka.
4. Ibyavuzwe haruguru nuburyo bwo kumenya nibaUbushyuhe bwa PT100ni ibicuruzwa bisanzwe.Nizeye gufasha abantu bose.Niba ufite ikibazo, urashobora guhamagara abakozi bacu tekinike.
