Yuav ua li cas siv lub zuag ntau los ntsuas qhov sib hloov pauv
Qhov sib thooj hloov tuaj yeem ntsuas nrog tus multimeter; Txoj kev ntsuas ntsuas kuj yooj yim heev, tsuas yog kho nws ua tus hloov.
Yog li, cia peb kawm paub dab tsi li no enximity hloov yog raws nraim.
Qhov sib thooj hloov, raws li lub npe tawm tswv yim, yog tus hloov pauv uas tsuas yog ua haujlwm thaum nws "ze". Qhov sib thooj hloov yuav tsum tau muab cais ua txoj haujlwm hloov, thiab qhov sib txawv ntawm kev sib tw tau ua tiav txoj hauj lwm ntsuas ua haujlwm tsis tau kov cov khoom ntsuas.
Hauv ntej, cov ntsiab lus ntawm cov hloov pauv tsis yog qhov hloov chaw, tab sis tus ua haujlwm ntawm txoj cai no sib txawv. Tam sim no, cov sib thooj tsis sib xws ntawm kev ua lag luam tuaj yeem raug faib ua cov hauv qab no:
Photoelectric sib thooj hloov: los ntawm kev cuam tshuam ntawm lub teeb, thaum muaj kev khuam siab thaiv lub teeb pom kev, lub cuab yeej yuav tsim tsim kom muaj lub teeb liab lossis tawm ntawm lub teeb liab.
HALT HOM FUTTERYDER PUREAS PLAY: Koj yuav tsis paub nrog lo lus Hall tseem. Qhov tseeb, Hall yog ib daim ntawv ntawm Circuit Court uas muaj kev nkag siab rau cov tshuaj sib nqus. Thaum cov khoom sib nqus tau kuaj pom, lub Circuit Court yuav hloov pauv thiab tso zis ntawm kev hloov pauv / tawm ntawm txoj kev hloov dua tshiab
Capacitive sib thooj hloov pauv: thaum nws los txog rau capercharitive hloov, peb yuav tsum nkag siab qhov teeb meem ntawm dielectric tas li. Thaum ib qho khoom dhau ntawm ob daim phiaj ntawm lub catacitor, kev hloov pauv tsis tu ncua, tsim lub teeb liab uas tau hloov dua siab tshiab thiab hloov mus los ntawm Circuit Court.
Yuav ua li cas siv ntau ntau li ntsuas ntsuas qhov sib thooj?
Txawm hais tias nws tseem yog hloov, ntsuas ntawm qhov kev hloov pauv no yog qhov tshwj xeeb me ntsis. Yog tias peb ntsuas nws ncaj qha, peb yuav twv tsis tau dab tsi vim tias cov khoom siv hluav taws xob uas xav tau txuas nrog lub zog hluav taws xob, thiab lawv feem ntau yog 24V DC.
Tom qab muab hluav taws xob rau qhov sib thooj hloov, peb kuj yuav tsum nkag siab txog txoj kev sib txuas hauv txoj kev sab hauv. Noj peb xaim sib faib hloov ua ib qho piv txwv, cov phooj ywg uas nkag siab qee qhov kev paub ntawm thaj tsam tau yooj yim ntxiv tias qhov kev hloov pauv tau yooj yim dua yog cuam tshuam nrog tus transistor. Thaum lub Circuit Court tseem ceeb ntawm qhov sib thooj hloov cov khoom ntiag tug, nws yuav ua rau kev hloov pauv ntawm Circuit Court. Qhov no yuav tau kaw Circuit Court ntawm ob qho kawg ntawm lub nra hauv daim duab, uas yog, kev muab fais fab ntawm 24V fais fab ntxiv rau ob sab ntawm lub nra. Qhov no yog qhov tseeb tus ua haujlwm ntawm txoj kev hloov pauv.
