Thaum peb siv cov khoom siv hluav taws xob, peb yuav pom tias cov xov tooj ntawm tes, TVs, tub yees, thiab lwm yam yuav kub tom qab ua haujlwm ntev, tab sis thaum lub xov tooj ntawm tes thiab TV tsis ua haujlwm, qhov kub thiab txias yuav maj mam poob. Yog vim li cas? Qhov tseeb, qhov kub nce yog cuam tshuam nrog hluav taws xob.
Cov khoom siv hluav taws xob yuav tsum txuas nrog lub zog hluav taws xob ua haujlwm, thiab tsis muaj lub zog, cov khoom siv hluav taws xob tsis tuaj yeem pib ua haujlwm. Tam sim no thiab qhov kub thiab txias muaj feem cuam tshuam, feem ntau proportional rau kev sib raug zoo, nyob rau hauv ib tug tej yam voltage range, qhov ntau dua tam sim no, qhov kub thiab txias. Thiab lub cev muaj zog lub cev muaj zog loj, qhov ntau dua qhov xav tau tam sim no, qhov ntau dua tam sim no, qhov kub thiab txias. Txawm li cas los xij, kev khiav hauj lwm kub ntawm lub cev muaj zog yog txwv, ib zaug qhov kub ntawm cov khoom siv hluav taws xob yog ib qho yooj yim rau luv luv Circuit Court, hluav taws xob luv luv Circuit Court yuav tsis tsuas yog tawg puas tsuaj rau cov khoom siv hluav taws xob, tab sis kuj ua rau tus neeg mob.
Yog li ntawd, cov khoom siv hluav taws xob yuav tsum tau tswj qhov kub thiab txias thaum ua haujlwm, thiab thaum kub nce mus rau ib theem, qhov kub thiab txias yog tswj kom poob qis. Cov khoom siv hluav taws xob uas ua rau cov khoom siv hluav taws xob kub - cov khoom siv hluav taws xob - thermistor.
Thermistor yog cov khoom siv hluav taws xob kub-rhiab heev uas muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov kub thiab txias. Thermistors yog tsim los ntawm cov khoom siv semiconductor thiab yog cov khoom siv semiconductor.
Thermistors tau muab faib ua ob pawg raws li qhov kub thiab txias coefficient: qhov zoo kub coefficient thermistors, hu ua PTC thermistors, nyob rau hauv ib qho kev ntsuas kub, tus nqi kuj nce ntxiv nrog qhov kub thiab txias; Tsis zoo kub coefficient thermistors, hu ua NTC thermistor, nyob rau hauv ib tug tej yam kub thiab txias, qhov tsis kam txo nrog qhov kub thiab txias.
NTC thermistor tuaj yeem ua lub luag haujlwm ntawm kev ntsuas kub thiab ntsuas kub kom ntseeg tau tias cov khoom siv hluav taws xob yuav tsis raug luv luv thiab tawg vim qhov kub thiab txias thaum ua haujlwm, thiab tuaj yeem xyuas kom meej tias lub roj teeb ntawm tes ua haujlwm nyob rau hauv qhov kub thiab txias ntawm cov khoom siv hluav taws xob. nquag nres ua haujlwm ntawm qhov kub thiab txias.
Yog tias cov khoom siv hluav taws xob ua haujlwm nyob rau hauv luv luv Circuit Court tawg, ntxiv rau kev xyuam xim rau lub hwj chim mov voltage siab dhau lawm, tab sis kuj yuav tsum xyuam xim rau seb lub NTC thermistor yog qis dua los yog laus, inferior NTC thermistor tuaj yeem ua rau hluav taws xob luv luv- Circuit Court tawg, thiab NTC thermistor kev laus, kev ua haujlwm tsis ruaj khov kuj yuav ua rau hluav taws xob luv luv tawg, yuav tsum tau hloov lub sijhawm.
