Ubushuhe bubi (NTC) thermistors bukoreshwa nkibikoresho byo hejuru byerekana ubushyuhe bukabije muburyo butandukanye bwimodoka, inganda, ibikoresho byo murugo hamwe nubuvuzi.Kuberako ubwoko butandukanye bwa NTC thermistors burahari - bwakozwe nibishushanyo bitandukanye kandi bikozwe mubikoresho bitandukanye - guhitamo ibyizaNTC thermistorskuri porogaramu runaka irashobora kuba ingorabahizi.

Hariho uburyo butatu bukuru bwa tekinoroji yubushyuhe, buriwese ufite ibiyiranga: ibyuma byerekana ubushyuhe bwo kurwanya ubushyuhe (RTD) hamwe nubwoko bubiri bwa thermistors, positif nziza nubushyuhe bubi.Rukuruzi ya RTD ikoreshwa cyane cyane mugupima ubushyuhe butandukanye, kandi kubera ko ikoresha ibyuma byera, usanga bihenze kuruta thermistors.
Kubwibyo, kubera ko thermistors ipima ubushyuhe hamwe nukuri cyangwa neza, mubisanzwe bikundwa na RTDS.Nkuko izina ribivuga, kurwanya ubukonje bwiza (PTC) ubushyuhe bwiyongera hamwe nubushyuhe.Bakunze gukoreshwa nkubushyuhe bwo kugabanya ubushyuhe mu kuzimya cyangwa kuzenguruka umutekano kuko kurwanya biriyongera iyo ubushyuhe bwo guhinduka bumaze kugera.Ku rundi ruhande, uko ubushyuhe bwiyongera, ubukana bwa coeffisente yubushyuhe bubi (NTC) buragabanuka.Kurwanya ubushyuhe (RT) nuburinganire buringaniye, kubwibyo birasobanutse neza kandi bihamye kubipimo byubushyuhe.
Ibipimo byingenzi byo guhitamo
Ubushyuhe bwa NTC burakomeye cyane kandi burashobora gupima ubushyuhe hamwe nukuri (± 0.1 ° C), bigatuma biba byiza muburyo butandukanye bwo gusaba.Ariko, guhitamo ubwoko bwubwoko bushingiye kubintu byinshi - urugero rwubushyuhe, intera irwanya, gupima neza, ibidukikije, igihe cyo gusubiza, nubunini busabwa.
Epoxy isize ibintu bya NTC birakomeye kandi mubisanzwe bipima ubushyuhe buri hagati ya -55 ° C na + 155 ° C, mugihe ibirahuri bya NTC bifunze ibirahuri bigera kuri + 300 ° C.Kuri porogaramu zisaba ibihe byihuse byo gusubiza, ibirahuri bifunze ibirahuri nibyiza guhitamo.Nibindi byoroshye, hamwe na diametero ntoya nka 0.8mm.
Ni ngombwa guhuza ubushyuhe bwa thermistor ya NTC nubushyuhe bwibigize bitera ubushyuhe guhinduka.Nkigisubizo, ntibiboneka gusa muburyo bwa gakondo hamwe na sisitemu, ariko birashobora no gushirwa mumazu yo mu bwoko bwa screw kugirango ihuze na radiator kugirango igere hejuru.
Agashya ku isoko ni bayobora rwose (chip hamwe nibigize) NTC thermistors yujuje ibyangombwa bisabwa byubuyobozi bwa RoSH2.

Ibice bya sensor ya sisitemu na sisitemu bishyirwa mubikorwa bitandukanye, cyane cyane mumodoka.Ubusanzwe porogaramu zirimo ibiziga bishyushye hamwe nintebe, hamwe na sisitemu igoye yo kurwanya ikirere.Thermistors ikoreshwa muri sisitemu ya gaze ya gaze (EGR), ibyuma bifata ibyuma bifata ibyuma (AIM), hamwe nubushyuhe hamwe numuvuduko mwinshi (TMAP).Ubushyuhe bwagutse bwibikorwa bifite imbaraga nyinshi zo kurwanya no kunyeganyega, kwizerwa cyane, no kuramba hamwe nigihe kirekire.Niba thermistors igomba gukoreshwa mubikoresho byimodoka, noneho guhangana ningutu AEC-Q200 kwisi yose hano ni itegeko.
Mu binyabiziga byamashanyarazi n’ibivange, ibyuma bya NTC bikoreshwa mukurinda umutekano wa bateri, kugenzura imiyoboro y’amashanyarazi no guhagarara.Sisitemu yo gukonjesha ya firigo ikonjesha bateri ihujwe na sisitemu yo guhumeka.
Ubushyuhe bwo kugenzura no kugenzura mubikoresho byo murugo bikubiyemo ubushyuhe butandukanye.Kurugero, mumyenda yumye, aubushyuheigena ubushyuhe bwumwuka ushyushye ujya mu ngoma nubushyuhe bwumwuka usohoka uko usohoka ingoma.Gukonjesha no gukonjesha ,.NTC sensorapima ubushyuhe mucyumba gikonjesha, abuza guhumeka gukonja, kandi akamenya ubushyuhe bwibidukikije.Mubikoresho bito nkibyuma, abakora ikawa hamwe nindobo, ibyuma byubushyuhe bikoreshwa mumutekano no gukoresha ingufu.Ibice byo gushyushya, guhumeka no guhumeka (HVAC) bifata igice kinini cyisoko.
Gukura Kumurima
Ubuvuzi bwa elegitoroniki yubuvuzi bufite ibikoresho bitandukanye byo kuvura abarwayi, hanze, ndetse no kwita ku rugo.Ubushyuhe bwa NTC bukoreshwa nkibikoresho byerekana ubushyuhe mubikoresho byubuvuzi.
Iyo igikoresho gito cyubuvuzi kigendanwa kirimo kwishyurwa, ubushyuhe bwimikorere ya bateri yumuriro igomba guhora ikurikiranwa.Ni ukubera ko amashanyarazi ya reaction ikoreshwa mugihe cyo gukurikirana ahanini biterwa nubushyuhe, kuburyo bwihuse, isesengura ryukuri ni ngombwa.
Gukurikirana Glucose Monitoring (GCM) birashobora gukurikirana isukari mu maraso ku barwayi ba diyabete.Hano, sensor ya NTC ikoreshwa mugupima ubushyuhe, kuko ibi bishobora kugira ingaruka kubisubizo.
Gukomeza kuvura umwuka mwiza (CPAP) ukoresha imashini ifasha abantu bafite ibitotsi apnea guhumeka byoroshye mugihe cyo gusinzira.Mu buryo nk'ubwo, ku ndwara zikomeye z'ubuhumekero, nka COVID-19, imashini zikoresha imashini zifata umwuka uhumeka umurwayi ukanda buhoro buhoro mu bihaha no gukuramo dioxyde de carbone.Muri ubwo buryo bwombi, ibyuma bifata ibirahure bya NTC byinjijwe mu kirere, mu kirere no mu kanwa kugira ngo bipime ubushyuhe bw’ikirere kugira ngo abarwayi bakomeze kumererwa neza.
Icyorezo cya vuba cyatumye hakenerwa sensibilité nukuri kuri sensor ya NTC hamwe nigihe kirekire.Ikizamini gishya cya virusi gifite ibisabwa kugirango igenzure ubushyuhe kugirango habeho kwitwara neza hagati yicyitegererezo na reagent.Isaha yubwenge nayo ihujwe na sisitemu yo gukurikirana ubushyuhe kugirango iburire indwara zishobora kubaho.
