Lub Teeb Sensors. Lub teeb Sensor tsimib lub teeb liab tso tawm qhia qhov kev siv ntawm lub teeb los ntawm kev ntsuas lub zog radiant uas muaj nyob rau hauv qhov nqaim heev ntawm cov zaus pib hu ua "lub teeb", thiab qhov ntau zaus ntawm "Infra -red” rau “Visible” mus txog “Ultraviolet” lub teeb spectrum.
Dab tsi yog qhov ntsuas hluav taws xob?
Ib lub ntsuas hluav taws xob tam sim no lossis lub rooj tsavxwm saib xyuas hluav taws xob tam sim no hauv ntau daim ntawv thov. … Qhov no feem ntau hu ua "shunt resistor tam sim no ntsuas." Lub ntsuas hluav taws xob tam sim no tsim qhov sib faib tam sim no lossis qhov hluav taws xob tawm mus rau qhov tam sim no hauv txoj kev ntsuas.
sensors ua haujlwm li cas?
sensors ua haujlwm li cas? … Muab qhov yooj yim, lub sensor hloov stimuli xws li cua sov, lub teeb, suab thiab txav mus rau hauv hluav taws xob signals. Cov teeb liab no tau dhau los ntawm ib qho interface uas hloov lawv mus rau hauv binary code thiab kis qhov no mus rau lub computer kom ua tiav.
Lub luag haujlwm ntawm qhov ntsuas hluav taws xob yog dab tsi?
A sensor hloov lub cev ua haujlwm los ntsuas rau hauv hluav taws xob sib npaug thiab ua tiav nws kom cov hluav taws xob xaim hluav taws xob tau yooj yim xa mus thiab ua tiav ntxiv. Lub sensor tuaj yeem tso tawm seb qhov khoom puas nyob lossis tsis tshwm sim (binary) lossis qhov ntsuas tus nqi tau mus txog (analog lossis digital).
Photocells ua haujlwm li cas?
A photocell yog ib qho resistor uas hloov qhov tsis kam nyob ntawm seb lub teeb pom kev zoo li casxwm txheej ntawm nws. Lub photocell ua haujlwm ntawm semiconductor photoconductivity: lub zog ntawm photons tsoo lub semiconductor frees electrons ntws, txo qhov tsis kam.

Puas yog kev siv hluav taws xob siv hluav taws xob?
Usability engineering yog kev qhuab qhia uas tsom mus rau kev txhim kho kev siv tau ntawm kev sib tham sib. Nws rub tawm cov kev xav los ntawm kev tshawb fawb hauv computer thiab kev puas siab puas ntsws los txhais cov teeb meem uas tshwm sim thaum siv cov kab ke.
Lub tshuab hluav taws xob twg siv rau kev tsheb ciav hlau hluav taws xob?
TE Connectivity's (TE) optimized VESA nqus Circuit Court breaker rau railway electrification yog thawj tag nrho electro-magnetically ua system rau 25 kV thiab 15kV tsheb. Lub tshuab hluav taws xob twg siv hauv kev tsheb ciav hlau? 2.
Lub chaw nres tsheb hluav taws xob hluav taws xob puas tuaj yeem ua haujlwm?
Coal-fired cov nroj tsuag tsim hluav taws xob los ntawm kev hlawv cov thee hauv lub boiler los tsim cov pa. Cov chav uas tsim, nyob rau hauv lub siab loj heev, ntws mus rau hauv lub turbine, uas tig lub generator los tsim hluav taws xob. Cov chav yog txias, condensed rov qab mus rau hauv dej thiab rov qab mus rau lub boiler kom pib txheej txheem dua.
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
