Ihame ryakazi rya Thermopile Infrared Sensor - Ingaruka ya Thermoelectric

Ingaruka ya Thermoelectric (Ingaruka ya Seebeck)

Niba ibikoresho bibiri cyangwa ibintu bitandukanye A na B bifite ibikoresho bimwe mugihe hamwe nibikorwa bitandukanye byakazi, iyo bihujwe kumpera ishyushye (Agace gashyushye), byafunguwe kumpera ikonje (Agace gakonje), hamwe nubushyuhe buri hagati yubushyuhe Impera n'imbeho impera ni ΔT_HC, rero kumpera ikonje hagiye kubaho ingufu za termoelektromotive V._hanze.

Iyo imirasire yo hanze itagira imirasire irasa ahantu ho kwinjirira, hashobora kwinjizwa imirasire ya infragre kandi ikayihindura ingufu zubushyuhe.Ubushyuhe buringaniye bizabyara ahantu hashyushye hamwe nubukonje bukonje.Binyuze muri Seebeck Ingaruka yibikoresho bya thermocouple, ubushyuhe bwa gradient burashobora guhinduka mubimenyetso bya voltage bisohoka.

Ingaruka ya Thermoelectric (Ingaruka ya Seebeck)

Muyunguruzi.

Cap: gushyigikira imashini yububiko bwa IR muyunguruzi.

Chip Chip: kumva ibimenyetso bya infragre inyura muri IR muyunguruzi.

Umutwe: gushyigikira imiterere ya chip.

Chip Thermistor(Bihitamo): gukurikirana ubukonje bwahantu hakonje ubushyuhe bwa chip ya TPS.

ASIC itunganya chip.

Birashobora kugaragara ko ihame ryakazi rya chip ya thermopile sensor chip ari inshuro ebyiri zahinduwe kumubiri "urumuri-ubushyuhe-amashanyarazi".Ikintu icyo aricyo cyose kiri hejuru ya zeru (harimo numubiri wumuntu) gisohora imirasire yimirasire, niba uhisemo uburebure bwumurongo ubinyujije mumashanyarazi ya infragre (idirishya rya 5-14μm), mugihe ibintu byoroshye bitagaragara kuri chip bikurura ubushyuhe bwa infragre kandi bigahindura urumuri mubushyuhe , bivamo kuzamuka kwubushyuhe bwakarere kinjira, itandukaniro ryubushyuhe hagati yakarere kinjizwamo na zone ihuza imbeho ihindurwamo ingufu za voltage binyuze mumaseti amagana ya micro ya thermocouples ihuza, kandi ibimenyetso bya infragre bikamenyekana nyuma yumuriro wa voltage ni byakozwe.

Urebye ku miterere, izuba rya Sunshine Technologies ya thermopile infrared sensor itandukanye nibicuruzwa bisanzwe, imiterere yayo "yuzuye".Hano haribibazo byingenzi bya tekiniki kuriyi miterere, ni ukuvuga, uburyo bwo gushyira igipande cya 1μm yuburebure bwa firime ihagarikwa kumwanya wa mm 1 gusa², kandi urebe ko firime ishobora kugira igipimo gihagije cyo guhindura urumuri rwa infragre mu bisohoka byamashanyarazi, kugirango byuzuze ibimenyetso byerekana imbaraga za sensor.Ni ukubera ko Sunshine Technologies yatsinze kandi ikamenya neza ikoranabuhanga ryibanze rishobora gusenya monopole yigihe kirekire yibicuruzwa byamahanga mugihe kimwe.
