Ubushyuhe bwa sensor gukora ihame no gutoranya

Ukuntu abadermocouple bakorera

Iyo hari abakoresha babiri batandukanye a na b kugirango bakore ikirahure, kandi impera zombi zirahujwe hagati cyangwa ubushyuhe bwinyuma, ni ukuvuga ubushyuhe bwinyuma, ni ukuvuga Iherezo ryibintu bihari muri loop byitwa The imbaraga za thermoeletroluveotive. Iki kintu cyo kubyara ingufu zamagorofa kubera gutandukana mubushyuhe bwitwa ingaruka zo kureba. Hano hari ingaruka ebyiri zijyanye no kubona: mbere, iyo ubushyuhe bunyuze mu buryo butandukanye bwabasebanya, ubushyuhe bwinjizwe cyangwa kurekurwa hano (bitewe ningaruka za peltier; Icya kabiri, iyo ikirundo kinyuze kumurongo ufite ubushyuhe gradient, umuyobozi akurura cyangwa arekura ubushyuhe (bitewe nubukwe bwurukundo rwubushyuhe), uzwi kugirwa ingaruka za Thomson. Guhuza abayobora bibiri bitandukanye cyangwa ibice byitwa byitwa thermocouple.

Ukuntu bahanganye banga

Agaciro ko kurwana kwumuyobozi uhinduka nubushyuhe, kandi ubushyuhe bwikintu bwo gupimirwa bubarwa mugupima agaciro kirwanya. Uruseke rwashyizweho niri hame nintangarugero yubushyuhe, bukoreshwa cyane kubushyuhe mubushyuhe bwa -200-500 ° C. Gupima. Icyuma cyiza nigikoresho nyamukuru cyo kurwanya ubushyuhe, kandi ibikoresho byo kurwanya ubushyuhe bigomba kugira ibiranga bikurikira:

.

(2) Kurwanya cyane, ubushobozi buke bwubushyuhe hamwe numuvuduko wihuse.

(3) Ibikoresho bifite ikibazo cyiza nubukorikori, kandi igiciro ni gito.

(4) Imitungo mibi kandi yumubiri irahagaze mubushyuhe.

Kugeza ubu, Platinum n'umuringa bigakoreshwa cyane mu nganda, kandi byahinduwe ubushyuhe busanzwe bwo gupima ubushyuhe.

Gutekereza mugihe uhitamo ubushyuhe

1. Niba imiterere y'ibidukikije yikintu cyapimwe gifite ibyangiritse ku bushyuhe bwibiti.

2. Niba ubushyuhe bwikintu cyapimwe kigomba kwandikwa, guhangayikishwa no guhita bigenzurwa, kandi niba bigomba gupimwa no kwanduza kure. 3800 10000

3. Mugihe ubushyuhe bwibintu byapimwe hamwe nigihe, niba lag yubushyuhe bwibintu bishobora kuzuza ibisabwa ubushyuhe.

4. Ingano hamwe nukuri kwubushyuhe.

5. Niba ingano yubushyuhe bwibintu bikwiye.

6. Igiciro cyemewe kandi niba byoroshye gukoresha.

Uburyo bwo kwirinda amakosa

Mugihe ushyiraho no gukoresha ubushyuhe, amakosa akurikira agomba kwirindwa kugirango hamenyekane neza.

1. Amakosa yatewe no kwishyiriraho

Kurugero, umwanya wo kwishyiriraho hamwe no kwinjiza uburebure bwa thermocouple ntigishobora kwerekana ubushyuhe nyabwo bwitanura. Muyandi magambo, thermocouple ntigomba gushyirwaho hafi yumuryango no gushyushya, kandi kwinjiza ubujyakuzimu bigomba kuba byibuze inshuro 8 kugeza 10 diameter umuyoboro wo kurinda.

2. Ikosa ryo kurwanya ubushyuhe

Iyo ubushyuhe ari bwinshi, niba hari igice cy'ivu ryakara n'umukungugu urinzwe, biziritseho ikirere kiziyongera kandi kikabuza gukora ubushyuhe. Muri iki gihe, ibimenyetso byerekana ubushyuhe biri munsi yagaciro nyako k'ubushyuhe bwapimwe. Kubwibyo, hanze yuburinzi bwa TheRocouple bugomba kuba isuku kugirango bugabanye amakosa.

3.

Niba thermocouple yizewe, umwanda mwinshi cyangwa umunyu kubwo gushushanya umugozi bizaganisha ku kwitiranya ubushyuhe hamwe nubushyuhe bwinshi, bitazatera gusa ubushyuhe bwa metero Ikosa ryatewe nibi rimwe na rimwe rigera kuri Baidu.

4. Amakosa yatangijwe na inertia yubushyuhe

Iyi ngaruka ivugwa cyane cyane mugihe upima byihuse kuko ubushyuhe bwubushyuhe bwa TheRmouple itera metero yerekanwe kuri puter yerekana ko inyuma yubushyuhe bupimwa. Kubwibyo, umudozi hamwe na elecmal yubushyuhe bworoshye hamwe na diameter ntoya yo kurinda igomba gukoreshwa bishoboka. Iyo ubushyuhe bugizwe nibidukikije, umuyoboro urinda urashobora no kuvaho. Kubera ibipimo byo gupima, amplitude yubushyuhe bwamenyekanye na Thermocouple ni ntoya kurenza iy'itanura ry'ubushyuhe. Ikinini kinini gipima, gito amplitude yihindagurika rya termocouple nubunini bunini kuva ubushyuhe nyabwo.
