Kev txav mus tom ntej ntawm kev siv tshuab thiab khoom siv hluav taws xob, kev txhim kho thev naus laus zis tsis tuaj yeem tab sis cuam tshuam rau cov cuab yeej, cov txheej txheem thiab cov txheej txheem ntawm kev tiv thaiv tib neeg thiab cov khoom los ntawm hluav taws. Muaj ib zaug, nyob rau hauv lub reign ntawm John IV, nws tau nce mus rau qhia ib puag ncig-lub-clock lub luag hauj lwm ntawm tshwj xeeb yees - yees. Xws li "kev ceeb toom" tau pab ntsuas raws sijhawm thiab tiv thaiv tag nrho lub nroog kom tsis txhob muaj hluav taws kub hnyiab, tso cai rau kev puas tsuaj ntawm ob peb lub tsev txwv.
Hnub no, hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb hluav taws. Cov tshuab ntse muaj peev xwm tsis tsuas yog ntes hluav taws thaum ntxov tshaj plaws thiab qhia nws, tab sis kuj pib tua nws.
Lub "qhov muag" ntawm txhua qhov hluav taws xob tua hluav taws yog cov cuab yeej ntes - cov khoom siv ncaj qha teb rau qee yam hluav taws kub thiab tsim hluav taws xob tsim nyog. Cov cuab yeej DIP 34A muaj ntau yam kev ua haujlwm tshwj xeeb uas ua rau nws muaj peev xwm ua kom muaj txiaj ntsig ntawm kev tua hluav taws los ntawm qhov kev txiav txim ntawm qhov loj.automatic systems.
Txoj Cai Ua Haujlwm
Cov khoom siv thawj zaug siv hauv cov tshuab tsim rov qab rau hnub ntawm USSR tau hnov qab tsuas yog kub. Soldered nrog fusible (kwv yees li 60 ° C) solder, daim hlau elastic tau sib cais thaum cua sov, qhov hluav taws xob tiv tauj ploj, uas tau kaw los ntawm cov khoom tau txais.
Cov cuab yeej niaj hnub, tshwj xeeb yog suav tias yog DIP 34A, ua haujlwm sib txawv. Nws paub tias cov khoom siv kho qhov muag ntawm cov roj av muaj zog nyob ntawm qhov muaj impurities hauv lawv, nrog rau qhov kub thiab txias.
rays infrared tshwj xeeb tshaj yog rhiab rau qhov hloov me ntsis ntawm cov pa roj sib xyaw. Cov khoom ntawm lub cev no yog siv los ntawm DIP 34A detector rau kev tshawb pom hluav taws thaum ntxov.
Scope of application
Cov cuab yeej pib muaj LED - qhov chaw ntawm cov hluav taws xob infrared thiab lub receiver - lub kaw lus tshwj xeeb ntawm lo ntsiab muag thiab cov khoom siv hluav taws xob. Qhov sib txawv me me ntawm lawv yog txhua yam uas DIP 34A xav tau txhawm rau saib xyuas lub xeev ntawm cov khoom tiv thaiv. Cov cuab yeej hauv nqe lus nug yog tsim los saib xyuas lub xeev ntawm huab cua nyob rau hauv qhov chaw kaw thiab muab lub teeb liab thaum muaj kev hloov pauv. Los ntawm txoj kev, DIP 34A tuaj yeem qhia tsis tsuas yog hais txog qhov tshwm sim ntawm hluav taws. Cov yam ntxwv ntawm tus ntes no ua rau nws muaj peev xwm paub qhov txawv ntawm cov pa taws hauv chav thiab cov plua plav nkag mus rau hauv diffuser. Cov khoom siv hluav taws xob ntse, thaum ua cov teeb liab, paub qhov txawv txawm tias hluav taws kub hnyiab los ntawm cov pa luam yeeb (cov neeg haus luam yeeb tsis muaj teeb meem yog qhov ua rau hluav taws kub, qhov chaw ntawm 90% ntawm tag nrho.cuav cuav).
Nta thiab Specifications
Cov yam ntxwv tag nrho ntawm DIP 34A tuaj yeem pom thaum nyeem cov lus qhia, ntawm no tsuas yog qee qhov ntawm nws cov ntaub ntawv sib txawv:
- lub teeb liab ntse ua haujlwm muaj peev xwm paub qhov txawv ntawm qhov tshwm sim ntawm hluav taws kub los ntawm plua plav hauv chav, kab nkag mus rau lub diffuser, thiab muaj cov pa luam yeeb hauv huab cua;
- qhov kub tshaj plaws (los ntawm 30 degrees hauv qab xoom mus rau ntxiv rau 55) ua rau nws siv tau cov cuab yeej siv ob qho tib si hauv chav sov thiab tsis sov;
- teb me me heev inertia - tsis tshaj 10 vib nas this;
- me me tam sim no noj hauv hom kev ua haujlwm - txog ib nrab milliamp;
- kev pab cuam lub neej 10 xyoo.
