Hano hari bimwe byerekeranye nuburyo bwo guhitamo ibyuma bifata ibyuma:

Itondekanya n'ibiranga ibyuma bifata ibyuka: Ibyuma bifata ibice bigabanijwe muburyo bwo guhangana naubushobozi-Ubwoko, nuburyo bwibanze bwibicuruzwa nugutwikira ibintu byunvikana kuri substrate kugirango bibe byunvikana. Nyumaamaziimyuka yo mu kirere yamamajwe ku bintu byumva, impedance na dielectric ihoraho yibintu bihinduka ku buryo bugaragara, bityo bikagira ikintu cyumva neza.

Ukuri hamwe nigihe kirekire gihamye: Ubusobanuro bwibikoresho byubushyuhe bigomba kugera kuri ± 2% kugeza ± 5% RH. Biragoye kugera kuri uru rwego, kandi mubisanzwe, drift iri muri ± 2%. Ndetse no hejuru.

Ubushyuhecoefficient de sensorifike: Usibye kuba yunvikana nubushuhe bwibidukikije, ibyuma bifata ubushyuhe nabyo byumva cyane ubushyuhe. Ubushyuhe bwubushyuhe buri muri 0.2 kugeza 0.8% RH / ℃, kandi bimwe birashobora gutandukana bitewe nubushuhe bugereranije. Ubushyuhe buringaniye bwumubyimba wibyuma bigira ingaruka kuburyo butaziguye ingaruka zindishyi, kandi kugabanuka kwubushyuhe butari kumurongo akenshi binanirwa kugera kubisubizo byiza byindishyi.Gusahamwe nubushyuhe bwibikoresho bikurikirana indishyi zirashobora kugerwaho ingaruka zukuri. Ubushyuhe bwo gukora buringaniye bwa sensor nyinshi biragoye kurenga 40 ℃.

Imbaragaitangwa rya sensororo yubushuhe: Ibikoresho byinshi byunvikana nubushuhe nka ceramics yicyuma cya okiside, polymers, na lithium chloride bihindura imikorere cyangwa bikananirana mugihe ukoresheje DCvoltage. Kubwibyo, ibyo byuma bifata ibyuma bigomba gukoreshwa na ACimbaraga.

Guhinduranya: Kugeza ubu, hari ikibazo gikomeye hamwe no guhinduranya ibyuma bifata ibyuma. Ibyumviro byurugero rumwe ntibishobora guhinduka, bigira ingaruka zikomeye kumikoreshereze kandi bikongerera ingorane kubungabunga no gutangiza. Bamwe mubakora inganda bakoze ibishoboka bitandukanye muriki kibazo kandi bageze kubisubizo byiza.

Guhindura ubuhehere: Guhindura ubuhehere biragoye kuruta guhinduranya ubushyuhe. Ubusanzwe ibipimo bya termometero bikoreshwa muguhindura ubushyuhe, ariko kubushuhe bwubushuhe, uburyo bukoreshwa muburyo bwo guhinduranya umunyu wuzuye, kandi ubushyuhe nabwo bugomba gupimwa.

Uburyo butandukanye bwo kubanza gusuzuma imikorere ya sensororo yubushuhe: Mugihe hatabayeho kalibrasi igoye ya sensororo yubushuhe, uburyo bworoshye kandi bworoshye burashobora gukoreshwa mugucira urubanza imikorere yimikorere yubushyuhe.

Kwiyemeza guhuzagurika: Kugura ibyuma birenga bibiri byerekana ubushyuhe bwubwoko bumwe nuwabikoze. Byinshi, nibyiza. Shyira hamwe hanyuma ugereranye ibisohoka indangagaciro. Mugihe ibintu bimeze neza, reba neza ikizamini. Ibindi bizamini birashobora gukorwa mugihe cyo gufata amajwi mugihe cyamasaha 24, kandi ukareba mubihe bitandukanye nubushyuhe butandukanye, nkubushyuhe bwo hejuru, buciriritse, nubushyuhe buke, kugirango harebwe byimazeyo ibicuruzwa bihagaze neza, harimo nibiranga indishyi zubushyuhe.

Ubushuhe bwo gukanika ukoresheje umunwa cyangwa ukoresheje ubundi buryo bwo guhumeka: Itegereze ibyiyumvo byayo, imyororokere, iyinjizwa ry’amazi hamwe n’imikorere ya desorption, kimwe no gukemura hamwe n’ibicuruzwa byinshi.

Kwipimisha mumasanduku afunguye kandi afunze: Gereranya kandi ugerageze niba bihuye, kandi urebe ingaruka zumuriro.

Kwipimisha ku bushyuhe bwo hejuru kandi buke (ukurikije ibipimo biri mu gitabo): Gerageza kandi ugereranye nibyanditswe mbere na nyuma yo gusubira mubisanzwe, kugirango usuzume ubushyuhe bw’imihindagurikire y’ibicuruzwa no kureba niba ibicuruzwa bihuye.

Imikorere yibicuruzwa amaherezo biterwa nuburyo bwuzuye kandi bukwiye bwo kumenya ishami rishinzwe kugenzura ubuziranenge. Uwitekakwiyuzuzamoigisubizo cyumunyu gikoreshwa muri kalibrasi, cyangwa ibicuruzwa birashobora kugereranywa no kugeragezwa. Ihagarikwa ryigihe kirekire mugihe kirekire cyo gukoresha ibicuruzwa naryo rirakenewe kugirango dusuzume neza ubuziranenge bwikigereranyo.

Isesengura ryibicuruzwa byinshi byerekana ubushyuhe ku isoko: Ibicuruzwa byinshi byo mu gihugu ndetse n’amahanga biva mu mahanga byagaragaye ku isoko, hamwe n’ubushuhe bwo mu bwoko bwa capacitance-byoroshyeibintu nibisanzwe. Ubwoko bwibikoresho byunvikana birimo polymers, lithiumchloride, na okiside y'icyuma.

Ibyiza bya capacitance-ubwoko bwamazi-yunvikana nibintu byihuta byihuta, ubunini buto, hamwe numurongo mwiza. Birasa neza. Ibicuruzwa bimwe byo hanze nabyo bifite imikorere yubushyuhe bwo hejuru. Nyamara, ibicuruzwa bikora cyane byubwoko nkubu biva mumahanga kandi bihenze cyane. Ibicuruzwa bimwe bihendutse ku isoko akenshi binanirwa kubahiriza ibipimo byavuzwe haruguru, hamwe n'umurongo mubi, guhuza, no kubyara. Guhindagurika mubushuhe bwo hepfo no hejuru (munsi ya 30% RH no hejuru ya 80% RH) ni ngombwa. Ibicuruzwa bimwe bikoresha microcomputer imwe imwe kugirango yishyure kandi ikosorwe, bigabanya ubunyangamugayo kandi bitangiza amakosa yo gutandukana kwinshi no kutagira umurongo mubi. Hatitawe ku bushobozi bwo hejuru cyangwa buke-bwa-capacitance-ubwoko bwibintu byumva neza, guhagarara igihe kirekire ntabwo ari byiza. Nyuma yo kumara igihe kirekire ikoreshwa, drift akenshi irakomeye, kandi ihindagurika-ryumva nezaubushoboziindangagaciro ziri kurwego rwa pF. Ihinduka rya 1% RH ntiri munsi ya 0.5 pF, kandi gutembera kwagaciro ka capacitance akenshi bitera amakosa ya RH% icumi. Ubwoko bwinshi bwa capacitance-yubushuhe bwibintu bidafite ubushobozi bwo gukora kubushyuhe buri hejuru ya 40 ℃, kandi akenshi birananirana cyangwa byangiritse.

Ubushobozi bwimyororokere yibintu nabyo bifite utunenge mubijyanye no kurwanya ruswa. Bakunze gusaba urwego rwo hejuru rwisuku mubidukikije. Ibicuruzwa bimwe na bimwe bikunze gutsindwa nko kunanirwa kwumucyo no kunanirwa guhagarara. Ibyuma bya okiside ya ceramic yubushyuhe bifite ibyiza nkibya sensoritifike yubushyuhe, ariko ivumbi ryumukungugu wimyanda ya ceramic rishobora gutera ibice kunanirwa. Akenshi, uburyo bwo gukoresha ingufu kugirango ukureho umukungugu burakoreshwa, ariko ingaruka ntabwo ari nziza, kandi ntishobora gukoreshwa ahantu hashobora gutwikwa kandi haturika. Ibikoresho byo kumva Alumina ntibishobora gutsinda intege nke za "gusaza karemano" k'imiterere y'ubuso, kandi inzitizi ntizihinduka. Ibyuma bya oxyde ceramic nubushuhe bwanone bifite ingaruka mbi zigihe kirekire.

Litiyumu ya chloride yubushyuhe ifite inyungu zigaragara zo guhagarara neza kuramba. Binyuze mubikorwa bitunganijwe neza, ibikoresho byakozwe na sensor birashobora kugera kubwukuri buhanitse, guhagarara neza, no guhuza umurongo, bigatuma ubuzima bwigihe kirekire bwizewe. Litiyumu ya chloride yubushyuhe ntishobora gusimburwa nibindi bikoresho byunvikana mubijyanye nigihe kirekire.
