Ubushyuhe bwa Sensor Ihame ryakazi no guhitamo

Uburyo bwa Thermocouple Sensors ikora

Iyo hari imiyoboro ibiri itandukanye hamwe na semiconductor A na B kugirango bakore uruziga, kandi impande zombi zahujwe, mugihe cyose ubushyuhe bwibice byombi butandukanye, ubushyuhe bwuruhande rumwe ni T, bwitwa iherezo ryakazi cyangwa iherezo rishyushye, hamwe nubushyuhe bwurundi ruhande ni TO, bita impera yubusa cyangwa imbeho ikonje, hari umuyoboro mumuzinga, ni ukuvuga imbaraga za electromotive ziri mumuzinga zitwa imbaraga za thermoelectromotive. Iyi phenomenon yo kubyara ingufu za electromotive kubera itandukaniro ryubushyuhe yitwa ingaruka ya Seebeck. Hariho ingaruka ebyiri zijyanye na Seebeck: icya mbere, iyo umuyoboro unyuze mu masangano yimyanya ibiri itandukanye, ubushyuhe bwinjira cyangwa burekurwa hano (bitewe nicyerekezo cyumuyaga), aribyo bita Peltier effect; Icya kabiri, iyo umuyoboro unyuze mu kiyobora hamwe nubushyuhe bwikigereranyo, kiyobora ikurura cyangwa ikarekura ubushyuhe (bitewe nicyerekezo cyubu ugereranije nubushyuhe bwa gradient), bizwi nkingaruka za Thomson. Gukomatanya ibintu bibiri bitandukanye cyangwa semiconductor byitwa thermocouple.

Uburyo Sensors Zirwanya Zikora

Agaciro ko kwihanganira kiyobora guhinduka hamwe nubushyuhe, kandi ubushyuhe bwikintu bugomba gupimwa bubarwa mugupima agaciro kangana. Rukuruzi rwakozwe n'iri hame ni sensor yubushyuhe bwo kurwanya, ikoreshwa cyane cyane kubushyuhe buri hagati yubushyuhe bwa -200-500 ° C. Igipimo. Icyuma cyiza nicyo kintu cyingenzi cyo gukora ubushyuhe bwo kurwanya ubushyuhe, kandi ibikoresho byo kurwanya ubushyuhe bigomba kugira ibintu bikurikira:

.

(2) Kurwanya cyane, ubushobozi buke bwubushyuhe n'umuvuduko wihuse.

(3) Ibikoresho bifite imyororokere myiza nubukorikori, kandi igiciro ni gito.

(4) Imiterere yimiti niyumubiri irahagaze murwego rwo gupima ubushyuhe.

Kugeza ubu, platine n'umuringa nibyo bikoreshwa cyane mu nganda, kandi byakozwe mu bushyuhe busanzwe bupima ubushyuhe bw’umuriro.

Ibitekerezo mugihe uhisemo icyuma gipima ubushyuhe

1. Niba ibidukikije ibidukikije byapimwe bifite ibyangiritse kubintu bipima ubushyuhe.

2. Niba ubushyuhe bwikintu cyapimwe bugomba kwandikwa, guhagarika umutima no guhita bigenzurwa, kandi niba bigomba gupimwa no koherezwa kure. 3800 100

3. Mugihe mugihe ubushyuhe bwikintu cyapimwe gihinduka mugihe, niba gutinda kwibintu bipima ubushyuhe bishobora kuzuza ibisabwa byo gupima ubushyuhe.

4. Ingano nukuri kurwego rwo gupima ubushyuhe.

5. Niba ingano yikintu gipima ubushyuhe gikwiye.

6. Igiciro cyemejwe kandi niba ari byiza gukoresha.

Uburyo bwo kwirinda amakosa

Mugihe ushyiraho kandi ukoresha sensor yubushyuhe, amakosa akurikira agomba kwirindwa kugirango hamenyekane ingaruka nziza zo gupima.

1. Amakosa yatewe no kwishyiriraho nabi

Kurugero, imyanya yo kwishyiriraho hamwe nubushakashatsi bwimbitse bwa thermocouple ntishobora kwerekana ubushyuhe nyabwo bwitanura. Muyandi magambo, thermocouple ntigomba gushyirwaho hafi yumuryango no gushyushya, kandi ubujyakuzimu bugomba kuba byibuze inshuro 8 kugeza 10 z'umurambararo wa diameter.

2. Ikosa ryo kurwanya ubushyuhe

Iyo ubushyuhe buri hejuru, niba hari urwego rw ivu ryamakara kumuyoboro urinda kandi umukungugu wongeyeho, kurwanya ubushyuhe biziyongera kandi bibuza gutwara ubushyuhe. Muri iki gihe, agaciro kerekana ubushyuhe kari munsi yagaciro nyako k'ubushyuhe bwapimwe. Kubwibyo, hanze yumuyoboro urinda thermocouple ugomba guhorana isuku kugirango ugabanye amakosa.

3. Amakosa aterwa no gukumira nabi

Niba thermocouple ikingiwe, umwanda mwinshi cyangwa umunyu mwinshi kumuyoboro urinda hamwe nu rubaho rwo gushushanya insinga bizatuma habaho kwangirika nabi hagati ya thermocouple nurukuta rwitanura, rukaba rukomeye cyane mubushyuhe bwinshi, ntibizatera igihombo gusa ubushobozi bwa thermoelectric ariko nanone butangiza intervention. Ikosa ryatewe nibi rishobora rimwe na rimwe kugera kuri Baidu.

4. Amakosa yatangijwe nubushuhe bwumuriro

Ingaruka zigaragara cyane cyane mugupima byihuse kuko inertia yumuriro wa thermocouple itera agaciro kerekanwe na metero inyuma yimihindagurikire yubushyuhe bupimwa. Kubwibyo, thermocouple hamwe na electrode yoroheje yubushyuhe hamwe na diameter ntoya ya tube irinda igomba gukoreshwa bishoboka. Iyo ibidukikije bipima ubushyuhe byemewe, umuyoboro urinda ushobora no gukurwaho. Bitewe no gutinda gupimwa, amplitione yubushyuhe bwubushyuhe bwagaragajwe na thermocouple ni ntoya kuruta ihindagurika ryubushyuhe bwitanura. Ninini yo gupima gutinda, ntoya amplitude yubushyuhe bwa thermocouple kandi nini itandukaniro nubushyuhe bwitanura.
