-Thermistor
Lub thermistor yog ib qho khoom siv ntsuas kub uas nws tsis kam ua haujlwm ntawm nws qhov kub thiab txias. Muaj ob hom thermistors: PTC (Positive Temperature Coefficient) thiab NTC (Negative Temperature Coefficient). Qhov tsis kam ntawm PTC thermistor nce nrog qhov kub thiab txias. Hauv qhov sib piv, qhov tsis kam ntawm NTC thermistor txo qis nrog qhov kub thiab txias, thiab hom thermistor zoo li yog cov thermistor feem ntau siv.
-Thermocouple
Thermocouples feem ntau yog siv los ntsuas qhov kub thiab txias ntau dua. Thermocouples ua haujlwm ntawm lub hauv paus ntsiab lus uas txhua tus neeg xyuas pib raug thermal gradient tsim ib qho hluav taws xob me me, qhov tshwm sim hu ua Seebeck effect. Qhov loj ntawm qhov generated voltage nyob ntawm seb hom hlau. Muaj ntau hom thermocouples nyob ntawm cov khoom siv hlau siv. Ntawm lawv, kev sib xyaw ua ke ntawm alloy tau ua nrov. Cov khoom sib txawv ntawm cov hlau sib txuas muaj rau cov ntawv thov sib txawv, thiab cov neeg siv feem ntau xaiv lawv raws li qhov xav tau ntawm qhov kub thiab txias.
-Resistance Kub Detector (RTD)
Resistance temperature detectors, tseem hu ua resistance thermometers. RTDs zoo ib yam li cov thermistor nyob rau hauv uas lawv tsis kam hloov nrog kub. Txawm li cas los xij, es tsis txhob siv cov ntaub ntawv tshwj xeeb uas nkag siab txog qhov kub thiab txias xws li thermistors, RTDs siv cov coils raug mob nyob ib ncig ntawm cov tub ntxhais hlau ua los ntawm ceramic lossis iav. RTD hlau yog cov khoom siv ntshiab, feem ntau yog platinum, npib tsib xee lossis tooj liab, thiab cov khoom siv no muaj kev sib raug zoo-kub kub uas siv los txiav txim qhov ntsuas kub.
-Analog tus pas ntsuas kub IC
Lwm txoj hauv kev siv cov thermistor thiab tus nqi ruaj khov hauv qhov hluav taws xob faib hluav taws xob yog simulate qhov ntsuas kub tsis tshua muaj hluav taws xob. Nyob rau hauv sib piv rau thermistors, analog ICs muab ib tug yuav luag linear output voltage.
-Digital Thermometer IC
Cov cuab yeej ntsuas kub digital yog qhov nyuaj dua, tab sis lawv tuaj yeem ua tau zoo heev. Tsis tas li ntawd, lawv tuaj yeem ua kom yooj yim rau txhua tus qauv tsim vim tias qhov kev hloov pauv ntawm analog-rau-digital tshwm sim hauv tus pas ntsuas kub IC es tsis yog cov cuab yeej cais xws li microcontroller. Tsis tas li ntawd, qee qhov ICs digital tuaj yeem teeb tsa los sau lub zog los ntawm lawv cov ntaub ntawv kab, tso cai rau kev sib txuas siv tsuas yog ob lub xov hlau (xws li cov ntaub ntawv / lub zog thiab hauv av).
