Dab tsi yog qhov sib txawv ntawm ntau hom kev ntsuas kub?

Muaj ntau ntau hom ntsuas kub ntsuas gadgets, txhua tus nrog nws tus kheej yam ntxwv. Thaum nws cuam tshuam nrog thermocouples, txoj cai ntawm no yog ntau qhov kev hloov pauv piv rau ntau hom.
Thermocouples. Thermocouples yog dav siv rau qhov kub thiab txias vim lawv qhov kub thiab txias ntau yam, durability, thiab cov nqi sib piv. Lawv paintings feem ntau raws li tag nrho ntawm cov nyhuv Seebeck, nyob rau hauv uas ib tug voltage yog generated thaum txawv txawv hlau yog koom nyob rau hauv txawv txawv kub. Kev sib txawv ntawm cov thermocouples yuav tsum muaj rau qhov kub thiab txias tiers thiab pob khoom. Piv txwv li, hom K thermocouples feem ntau yog siv rau hauv kev lag luam chaw, thaum hom T thermocouples yog tsim nyog rau cov pob khoom kub.
Resistance temperature detectors (RTDs). RTDs degree kub nrog kev pab ntawm kev siv kev hloov kho hauv hluav taws xob tsis kam. Lawv raug lees paub rau nws qhov tseeb thiab ruaj khov. RTDs feem ntau muab qhov raug siab dua li cov thermocouples, feem ntau ntawm qhov txo qis. Txawm li cas los xij, lawv tuaj yeem yog tus nqi siab ntxiv thiab tuaj yeem ua rau tsis yooj yim dua. RTDs nquag siv nyob rau hauv cov pob khoom uas yuav tsum tau muaj qhov tseeb ntau dhau, uas suav nrog cov chaw kuaj mob lossis cov txheej txheem tswj.
Thermistors. Thermistors yog cov khoom siv hluav taws xob semiconductor uas hloov lawv cov kev tiv thaiv nrog kub. Lawv tuaj yeem muab kev nkag siab ntau dhau thiab lub sijhawm ua haujlwm nrawm. Thermistors yuav tsum muaj nyob rau hauv txawv txawv hom, uas muaj xws li phem kub coefficient (NTC) thiab zoo kub coefficient (PTC). NTC thermistors feem ntau yog siv rau qhov ntsuas kub hauv cov neeg siv khoom siv hluav taws xob thiab cov pob tsheb. PTC thermistor yog nquag siv rau kev nyab xeeb overcurrent thiab tswj kub.
Infrared ntsuas kub. Infrared thermometers degree qhov kub thiab txias nrog kev pab los ntawm kev siv tshuaj xyuas cov hluav taws xob infrared emission nrog kev pab ntawm kev siv ib yam khoom. Lawv yog cov khoom siv uas tsis yog kov, uas ua rau lawv yooj yim rau kev ntsuas qhov kub thiab txias ntawm kev hloov khoom siv lossis hauv qhov chaw nyuaj. Cov ntsuas kub infrared feem ntau siv rau kev ntsuas kub luv luv hauv cov khoom lag luam thiab kev tshawb fawb. Txawm li cas los xij, tam sim no lawv yuav tsis raug raws li qhov sib txawv ntawm qhov ntsuas kub ntsuas gadgets thiab tej zaum yuav raug nteg qis nrog cov ntsiab lus uas suav nrog emissivity ntawm cov khoom raug ntsuas.
