    Workingkpụrụ Ọrụ nke Thermopile Infrared Sensor - Mmetụta Thermoelectric

    Mmetụta Thermoelectric (Seebeck Effect)

    Ọ bụrụ na ihe abụọ dị iche iche ma ọ bụ ihe A na B nke nwere otu ihe ahụ mgbe ha na-arụ ọrụ dị iche iche, mgbe ejikọtara ya na njedebe ọkụ (Mpaghara Ọkụ Na-ekpo ọkụ), meghere na njedebe oyi (Mpaghara Nzuzo Nzuzo), na gradient gradient n'etiti ọkụ ahụ. njedebe na njedebe oyi bụ ΔTHC, yabụ na njedebe oyi, a ga - enwe ike thermoelectromotive Vpụọ.

    Mgbe mpụga infrared nke dị na mpụga na-ekpochapụ mpaghara mmịnye nke onye nchọpụta, mpaghara absorption na-amịkọrọ ụzarị ọkụ infrared ma gbanwee ya n'ime ike ọkụ. A ga-emepụta gradient okpomọkụ na mpaghara nkwụsị ọkụ na mpaghara nkwụsị oyi. Site na Seebeck Effect nke ihe thermocouple, enwere ike ịtụgharị gradient na-arụ ọrụ na mgbaàmà mgbaàmà.

    Myọcha (njirimara njirimara IR bụ nhọrọ): họrọ bandị infrared, zere ogologo ntụgharị nke ọkụ iji metụta ihe mmetụta ahụ

    Cap: usoro nhazi nke IR filter

    TPS Mgbawa: ịghọta infrared mgbaàmà nke gafere site na IR iyo

    Nkụnye eji isi mee: ihe na-akwado usoro nhazi nke mgbawa

    Chip Thermistor (Nhọrọ): nyochaa nchikota uzo oyi nke TPS mgbawa

    ASIC na-arụ ọrụ mgbaàmà (nhọrọ, akara ngosi mgbapụta): ịchekwa mgbapụta analog nke mgbapụ TPS

    Enwere ike ihu ya na ụkpụrụ ọrụ nke ihe nrụpụta thermopile bụ okpukpu abụọ nke ntụgharị anụ ahụ nke "ọkụ-ọkụ ọkụ-ọkụ". Ihe ọ bụla dị n'elu efu zuru oke (gụnyere ahụ mmadụ) na-ewepụta ụzarị infrared, ma ọ bụrụ na họrọ ntụgharị ogologo kwesịrị ekwesị site na ntanetị infrared (windo 5-14μm), mgbe ihe ndị na-emetụ infrared na mgbawa na-etinye ọkụ infrared ma mee ka ọkụ ahụ bụrụ okpomọkụ , na - akpata ịrị elu okpomọkụ nke mpaghara absorption, ọdịiche ọnọdụ okpomọkụ dị n'etiti mpaghara absorption na mpaghara njikọta oyi na-agbanwe n'ime mmepụta volta site na narị otu narị usoro njikọ nke micro thermocouples njikọ, a na-ahụkwa mgbaama infrared mgbe mmepụta voltaji dị eme.

    N'ịhụ site na nhazi ahụ, Sunshine Technologies nke thermopile infrared sensor dị iche na ngwaahịa nkịtị, usoro ya "adịghị apụta". Enwere isi ike dị na teknụzụ maka usoro a, ya bụ, otu esi edobe ihe nkiri 1μm gbara ọkpụrụkpụ na mpaghara naanị 1 mm2, ma hụ na ihe nkiri ahụ nwere ike inwe ọnụego ntụgharị zuru oke iji gbanwee ọkụ infrared n'ime ihe mgbaàmà eletriki, ka o wee nwee ike ịchọta ihe ike chọrọ nke ihe mmetụta. Ọ bụ kpomkwem n'ihi Sunshine Teknụzụ emeriela ma nwee nnukwu teknụzụ a nke na ọ nwere ike imebi ikike nke ngwaahịa mba ofesi n'otu oge.
