Hotline Nta ntawm Anemometers
Qhov ntev ntawm cov hlau kub yog feem ntau nyob rau hauv qhov ntau ntawm {{0}} 5-2 hli, txoj kab uas hla yog nyob rau hauv thaj tsam ntawm 1-10 microns, thiab cov khoom yog platinum, tungsten los yog platinum-rhodium alloy. Yog tias nyias nyias (thickness tsawg dua 0.1 micron) hlau zaj duab xis yog siv los hloov cov hlau hlau, nws yog cov yeeb yaj kiab kub anemometer, uas muaj cov haujlwm zoo sib xws rau cov hlau kub, tab sis feem ntau yog siv rau ntsuas qhov ntws ntawm cov kua. Ntxiv rau qhov zoo tib yam ib leeg-xaim, cov hlau kub kuj tseem tuaj yeem ua ke ob-xaim lossis peb-xaim hom los ntsuas qhov nrawm ntawm txhua qhov kev qhia. Cov hluav taws xob teeb liab tso tawm los ntawm tus xov tooj hotline yog nkag mus rau hauv lub computer tom qab amplification, them nyiaj thiab digitization, uas tuaj yeem txhim kho qhov ntsuas qhov tseeb, tuaj yeem ua tiav cov ntaub ntawv tom qab ua tiav cov txheej txheem, thiab nthuav cov kev ntsuas ceev, xws li ua tiav cov nqi tam sim thiab lub sij hawm nruab nrab tus nqi, ua ke ceev thiab ib nrab ceev, thiab turbulence. thiab lwm yam kev ntsuas ntawm turbulence parameters. Piv nrog rau lub pitot raj, lub kub hlau anemometer muaj qhov zoo ntawm me me sojntsuam ntim, kev cuam tshuam me me rau qhov chaw ntws, cov lus teb ceev ceev, thiab tuaj yeem ntsuas qhov nrawm nrawm; tuaj yeem ntsuas qhov nrawm nrawm (xws li qis li 0.3 m / s).
