Intangiriro
Mu bushyuhegupimaporogaramu, ibikoresho bipima ubushyuhe bigira uruhare runini mu kumenya neza ubushyuhe, ibyo bikaba ari ingenzi mu kubara uburyo ubushyuhe butwara n'ikoreshwa ry'ingufu. Mu bwoko butandukanye bw'ibikoresho bipima ubushyuhe, ibikoresho bipima ubushyuhe birwanya platine (RTDs) bikoreshwa cyane bitewe nuko bifite ubuhanga bwo hejuru, bihamye, kandi bipima ubushyuhe bwinshi. Pt1000, Pt500, na Pt100 ni ubwoko busanzwe bwa RTD za platine, aho Pt1000 ari yo ikunze gutorwa mu bihe byinshi byo gupima ubushyuhe. Iyi nkuru izasuzuma impamvu Pt1000 ikunzwe cyane kandi ikavuga ku itandukaniro riri hagati ya Pt1000, Pt500, na Pt100.
Impamvu zo gukoresha cyane Pt1000 mu gupima ubushyuhe
Ubushobozi bwo kugaragaza ubushishozi buhanitse
Pt1000 ifite ubushobozi bwo guhangana n’ikirere bwa 1000 ohms kuri 0 °C, mu gihe Pt100 ifite ubushobozi bwo guhangana n’ikirere bwa 100 ohms ku bushyuhe bumwe, na Pt500 ifite ubushobozi bwo guhangana n’ikirere bwa 500 ohms kuri 0 °C. Ubushobozi bwo guhangana n’ikirere bwa Pt1000 butuma habaho impinduka nini mu bushyuhe buri kimwe. Urugero, ku bushyuhe buke, impinduka mu bushyuhe bwa Pt1000 ni ingenzi cyane ugereranije na Pt100 na Pt500. Ubu buryo bworoshye bwo gupima ubushyuhe, ibyo bikaba ari ingenzi cyane mugupima ubushyuheaho itandukaniro rito ry’ubushyuhe rishobora kugira ingaruka zikomeye ku buryo bufatika bwo kubara ubushyuhe. Mu bikorwa nka calorimetri ifite ubuziranenge bwo hejuru, aho impinduka z’ubushyuhe bw’iminota zigomba kugaragara neza kugira ngo hamenyekane neza uburyo ubushyuhe bwimuka, ubushobozi bwo kugaragaza ubushyuhe bwinshi bwa Pt1000 butanga inyungu idasanzwe.
Ingaruka zo kugabanya ubukana bw'insinga z'ubutare
Mu buryo bufatika bwo gupima ubushyuhe, sensor y'ubushyuhe ikunze guhuzwa n'igikoresho gipimisha binyuze mu nsinga z'icyuma. Ubudahangarwa bw'izi nsinga z'icyuma bushobora guteza amakosa mu gaciro ka RTD gapimye bityo bigatuma ubushyuhe bugira ingaruka ku buryo buhamye. Kubera ko Pt1000 ifite ubudahangarwa bwinshi bw'icyuma, ingaruka z'ubudahangarwa bw'icyuma cy'icyuma ku gipimo rusange cy'ubudahangarwa ni nto ugereranije na Pt100 na Pt500. Urugero, niba ubudahangarwa bw'icyuma cy'icyuma ari ohms nke, bizatera ikosa rinini ku ijana mu budahangarwa bwa Pt100 (hamwe n'ubudahangarwa bw'icyuma bwa 100 ohms) ugereranije na Pt1000 (hamwe n'ubudahangarwa bw'icyuma bwa 1000 ohms). Ibi bituma Pt1000 irushaho kuba nziza mu bikorwa aho uburebure bw'insinga z'icyuma bukenewe, nko muri sisitemu zo kohereza ubushyuhe mu nganda aho sensor y'ubushyuhe ishobora kuba iri kure y'icyumba cyo kugenzura.
Guhuza n'ibikoresho by'ikoranabuhanga bigezweho
Ibikoresho bigezweho byo gupima ikoranabuhanga byagenewe guhangana n'ibimenyetso byinshi byinjira. Pt1000, ifite ubushobozi bwo guhangana na 1000 - ohm nominal resistance kuri 0 °C, ihuye neza n'ubushobozi bwo gupima no gupima ibimenyetso bya sisitemu nyinshi zigezweho zo gupima no kugenzura. Izi sisitemu akenshi zinozwa kugira ngo zikore n'ibimenyetso bijyanye n'ubushyuhe bwa Pt1000. Urugero, module nyinshi zo gupima ubushyuhe zishingiye kuri microcontroller zikoreshwa mu buryo bwihariye mu gupima Pt1000, zitanga uburyo bworoshye bwo gukoresha hamwe n'isesengura ry'ubushyuhe. Ubu buryo bworoshye bwo koroshya imiterere n'ishyirwa mu bikorwa rya sisitemu zo gupima ubushyuhe, bigabanya gukenera uburyo bugoye bwo guhindura no gupima ibimenyetso.
Ibisabwa ku ikoreshwa ry’ubuhanga buhanitse
Igipimo cy'ubushyuheMu nzego zimwe na zimwe, nko mu bushakashatsi bwa siyansi, inganda zikora imiti, n’inganda zikora cyane, bisaba ibipimo by’ubushyuhe bihanitse cyane. Pt1000 ishobora kuzuza ibi bisabwa bitewe n’ubuziranenge bwayo n’ubudahinduka. Mu bushakashatsi bwa siyansi bujyanye na thermodynamics, gupima ubushyuhe neza ni ingenzi mu kwemeza ingero z’inyigisho. Ikosa rito mu gupima ubushyuhe rishobora gutuma habaho ihinduka rikomeye mu bisubizo byo kubara ubushyuhe. Pt1000, ifite imikorere myiza mu kumenya ubushyuhe neza, ihamya ko amakuru yo gupima ubushyuhe yabonetse yizewe kandi ashobora gushyigikira ubushakashatsi bwimbitse bwa siyansi n’uburyo bwo gukora umusaruro w’inganda bwiza.
Itandukaniro riri hagati ya Pt1000, Pt500, na Pt100
Agaciro ko kurwanya ku izina
Nkuko byavuzwe mbere, itandukaniro rigaragara cyane hagati ya Pt1000, Pt500, na Pt100 ni agaciro kazo ko kurwanya ikirere kuri 0 °C. Pt1000 ifite ubushobozi bwo kurwanya ikirere bwa 1000 ohms, Pt500 ifite 500 ohms, naho Pt100 ifite 100 ohms. Izi gaciro zitandukanye zo kurwanya ikirere zigira ingaruka ku buhanga bwazo n'ingaruka zo kurwanya icyuma cy'amashanyarazi nk'uko byasobanuwe haruguru. Guhitamo uburyo bwo kurwanya ikirere biterwa n'ibisabwa byihariye byagupima ubushyuheikoreshwa, nko kumenya neza ibipimo, uburebure bw'insinga z'icyuma, no guhuza na sisitemu yo gupima isanzweho.
Ubwitonzi n'Uburyo bwo Kumenya
Pt1000 muri rusange itanga ubushobozi bwo kumva neza muri ibyo bitatu, ikurikirwa na Pt500 hanyuma Pt100. Ubwo bushobozi bwo kumva bufitanye isano n'impinduka mu guhangana na dogere selisiyusi ku bushyuhe. Uko ubushobozi bwo kumva neza burushaho kwiyongera, ni ko ubushobozi bwo kumva neza burushaho kwiyongera, bigatuma ubushobozi bwo kumva neza burushaho kwiyongera. Mu bijyanye n'ubuziranenge, ubwoko bwose butatu bwa RTD za platine bushobora kugera ku buziranenge bwo hejuru iyo bugenzuwe neza. Ariko, bitewe n'ubuhanga bwayo bwo kumva neza, Pt1000 ishobora gutanga ibipimo by'ubushyuhe neza mu bikorwa aho itandukaniro rito ry'ubushyuhe rigomba gukemurwa neza. Urugero, mu isuzuma ry'ubushyuhe, aho itandukaniro ry'ubushyuhe hagati y'amazi yinjira n'asohoka rishobora kuba dogere selisiyusi nke gusa, Pt1000 ishobora gupima neza ayo tandukaniro rito kurusha Pt100.
Ikiguzi
Muri rusange, ikiguzi cya sensor za Pt1000 kiri hejuru ugereranyije n’icya Pt100 na Pt500. Ibi biterwa ahanini n’uko inzira yo gukora sensor za Pt1000 isaba igenzura ryimbitse kugira ngo igere ku gaciro ko hejuru k’ubudahangarwa bw’ingufu n’imikorere yayo yo hejuru. Ikiguzi cyo hejuru gishobora kuba ikintu kidashoboka mu bikorwa bimwe na bimwe by’ikiguzi. Ariko, mu bikorwa aho gupima ubushyuhe neza ari ingenzi, nko mu nganda zikora mu by’indege mu gucunga ubushyuhe bwa moteri cyangwa mu bikoresho by’ubuvuzi byo mu rwego rwo hejuru mu bikorwa bigenzurwa n’ubushyuhe, inyungu z’imikorere za Pt1000 zikunze kuruta ikiguzi. Pt100, ku rundi ruhande, ihendutse cyane kandi ishobora kuba ikwiriye gukoreshwa aho ubuziranenge bukenewe butari hejuru cyane, nko mu bikorwa bimwe na bimwe by’ibanze byo kugenzura ubushyuhe mu nganda.
Imiterere y'Ikoreshwa
Pt1000 ikoreshwa cyane cyane mu bikorwa aho hakenewe gupima ubushyuhe neza cyane, nko muri laboratwari z’ubushakashatsi mu igerageza rya kalorimetiri, mu nganda za semiconductor mu kugenzura ubushyuhe mu gihe cyo gutunganya wafer, no muri sisitemu za HVAC zo mu rwego rwo hejuru kugira ngo hapimwe neza ikoreshwa ry’ingufu. Pt500 ishobora gukoreshwa mu bikorwa bimwe na bimwe byo hagati aho ibisabwa mu buvuzi biri hejuru y’ibya Pt100 ariko bitari bikomeye nk’ibya Pt1000. Pt100, ifite igiciro gito kandi ikaba ikiri nziza ku bikorwa byinshi rusange, ikoreshwa cyane mu kugenzura ubushyuhe bw’inganda, nko mu kugenzura ubushyuhe bwa boiler, mu buryo bworoshye bwo kumenya ubushyuhe bw’icyumba mu nyubako, no mu kugenzura ubushyuhe bw’ibanze bwa moteri y’imodoka.
Umwanzuro
Mu gusoza, Pt1000 ikoreshwa cyane mu bushyuhegupimabitewe n’uburyo ikoresha cyane, ingaruka zayo zo kudakoresha insinga z’amashanyarazi zigabanuka, uburyo ikorana n’ibikoresho bigezweho, ndetse n’ubushobozi bwo guhaza ibisabwa mu buryo bunonosoye. Itandukaniro riri hagati ya Pt1000, Pt500, na Pt100 mu bijyanye n’agaciro k’ubudahangarwa, ubushobozi bwo gukoresha neza, uburyo ikoresha neza, ikiguzi, n’uburyo ikoreshwa bituma buri bwoko bukwiriye ibikenewe bitandukanye mu gupima ubushyuhe. Mu gihe uhitamo platine RTD yo gupima ubushyuhe, abahanga mu by’imashini n’abashushanya bagomba gusuzuma neza ibi bintu kugira ngo bahitemo sensor ikwiye cyane kugira ngo barebe ko hari ibisubizo nyabyo kandi byizewe byo gupima ubushyuhe.
