Lub hauv paus ntsiab lus thiab lub hom phiaj ntawm qhov ntsuas

Lub tog raj kheej yog tsim los ntawm microcrystalline iav ceramic cov ntaub ntawv, uas muaj lub tshuab nqus tsev zoo, siab thiab kub tsis kam, rwb thaiv tsev, thiab acid alkali corrosion kuj. Cov ntsuas kev ua tau zoo yog raws li hauv qab no: siv qhov kub thiab txias {{0}} degree ~ 1000 degree, ntim resistivity 1.08x1014 Ω · cm, thermal expansion coefficient: L=8.6x 10-6/degree, lub micro iav ceramic muaj thermal shock kuj zoo heev, thiab tsis tawg thaum quenched ntawm 800 degree mus rau 0 degree. Lub zog tsis hloov thaum quenched ntawm 200 degree mus rau 0 degree. Ib qho kawg ntawm lub tog raj kheej yog kho nrog nyias cov iav iav lub tog raj kheej nrog qhov ntev ntawm L=10cm, thiab lwm qhov kawg yog kho nrog lub ntsuas hluav taws xob infrared. Qhov kawg dawb ntawm cov organic iav pas nrig npog ib nrab ntawm qhov chaw tau txais qhov chaw ntawm lub raj infrared, ua rau nws ua haujlwm hauv cheeb tsam nrog qhov zoo tshaj plaws linearity. Vim lub thermal expansion coefficient ntawm cov iav organic yog 2=1.7x{15}}/degree, nrog rau qhov sib txawv ntawm txog li 2 qhov kev txiav txim ntawm qhov loj ntawm ob. Yog li, thaum qhov kub thiab txias hloov, nws tuaj yeem txiav txim siab tias qhov sib txawv ntawm cov iav organic ntawm cov khoom siv ceramic tuaj yeem tsis quav ntsej. Yog li ntawd, tus txheeb ze txoj hauj lwm hloov ntawm qhov dawb kawg ntawm cov iav organic thiab lub infrared hloov pauv sensor yuav hloov qhov chaw tau txais txiaj ntsig zoo ntawm lub raj txais infrared. Yog li, cov zis hluav taws xob ntawm qhov hloov pauv sensor kuj hloov raws li. Kev ntsuas rhiab heev ntawm hom tshiab ntawm qhov ntsuas kub no yog: Δ T=Δ L / L 1- ob

Ntawm lawv, △ L yog qhov rhiab heev ntawm infrared txav sensor rau qhov ntev ntawm cov iav organic.

Lub infrared hloov pauv sensor feem ntau yog tsim los ntawm lub teeb infrared-emitting diode emitting thiab txais cov cuab yeej, cov ntaub ntawv nthuav dav thiab denoising system, thiab cov ntaub ntawv tau txais thiab kev ua haujlwm.

Nws tuaj yeem pom tau tias txoj cai hloov hluav taws xob photoelectric ntawm infrared photoelectric diode yog siv los txiav txim lub occluder raws li kev sib raug zoo ntawm nws cov occluded luminous flux thiab cov zis tam sim no. Muaj peev xwm hloov qhov kub me me hloov mus rau qhov hloov pauv voltage. Siv lub amplification Circuit Court kom amplify nws. Tsim kom muaj kev sib raug zoo ntawm cov teeb liab hluav taws xob thiab qhov kub thiab txias siv daim npav khaws ntaub ntawv. Thaum kawg, nws yog qhov zoo rau kev ntsuas siab ntawm cov kauv micrometers kom ntsuas tau, ua rau muaj qhov ntsuas kev hloov pauv nrog qhov ntsuas qhov tseeb (310-7m).

Vim tias qhov me me tam sim no ntawm kev hloov pauv photoelectric thiab lub zog qis ntawm infrared lub teeb-emitting diodes, kuv tuaj yeem ntseeg tias infrared hloov pauv sensors yuav tsis muaj kev cuam tshuam rau qhov ntsuas kub ib puag ncig.
