Kev tshuaj ntsuam kub feem ntau txheeb xyuas ntawm kev ntsuas lub zog hluav taws xob thermal ntawm cov tshuaj thiab hloov nws mus rau hauv cov teeb liab nyeem tau yooj yim. Lub hauv paus ntsiab lus sib txawv raws li hom ntsuas kub siv. Nov yog cov ntsiab lus tseem ceeb hauv qab cov kev ntsuas ntsuas kub:
1.thermoounce:
Thermocouples yog raws li covSaib cov nyhuv, qhov twg ob cov hlau sib txawv tau koom nrog ib kawg. Thaum cov kev paub xaus xaus kev paub txog qhov kub thiab txias, nws ua rau qhov sib txawv ntawm qhov sib txawv ntawm cov xov hlau. Qhov kev ntsuas no tuaj yeem ntsuas tau thiab hloov pauv mus rau qhov kub nyeem ntawv.
2.Resistive cov thawj tshuaj ntsuam (RTDs):
RTDS ua haujlwm ntawm lub hauv paus ntsiab lus uas hluav taws xob tsis kam ntawm cov khoom hloov nrog ntsuas kub. Feem ntau feem ntau, platinum yog siv nyob rau hauv RTDs vim tias nws txoj kev tiv thaiv nyob rau hauv ib tug heev twv ua ntej thiab linear txoj kev kub heev. Los ntawm ntsuas qhov tsis kam, qhov ntsuas kub yuav txiav txim siab.
3.Qhov ntaub ntawv:
Tus thermaticors yog kub-rhiab resistors ua los ntawm cov ntaub ntawv ceramic. Lawv cov kev tawm tsam tiv thaiv kom tsawg dua li nce ntxiv (rau cov coefficient tsis zoo, lossis NTC, tus ua haujlwm kub). Kev sib raug zoo ntawm kev tawm tsam thiab kub yog tsis yog-linear, tab sis nws tuaj yeem ntsuas thiab siv rau ntsuas kub.
4.Infrared sensors:
Infrared kub sensors ua haujlwm los ntawm kev kuaj pom kev sib tw hluav taws xob tau tawm los ntawm cov khoom. Tus nqi ntawm infrared remiation emuction yog qhov sib npaug nrog qhov kub ntawm cov khoom. Lub sensor pom cov hluav taws xob no thiab siv nws los txiav txim qhov ntsuas kub tsis ua rau lub cev sib cuag.
5.Digital kub sensors(zoo li DS18b20):
Cov sensital sensors feem ntau siv lub thermistor lossis RTD caij los ntsuas kub. Cov sensors no muab cov zis digital digital desigital (1- xaim lossis i2c interface) uas tuaj yeem nyeem los ntawm microcontroller. Lub sensor feem ntau hloov kho qhov tsis kam lossis voltage hloov mus rau lub cim digital, uas ua rau nws yooj yim rau cov microcontrollers thiab cov digital tshuab.
Cov kev tshuaj ntsuam kub saib xyuas cov tshuab feem ntau yog tsim cov txheej txheem raug, xws li kev sib koom ua ke HVAC, lossis kev saib xyuas ib puag ncig hauv kev ua liaj ua teb thiab khoom noj khoom haus.
