Lub hauv paus ntsiab lus ua haujlwm ntawm lub thermocouple ua raws cov nyhuv Seebeck, lossis cov nyhuv thermoelectric, uas yog hais txog cov txheej txheem uas thermal zog hloov mus rau hauv hluav taws xob.
Txoj cai ua haujlwm ntawm thermocouple yog dab tsi?
Ib lub thermocouple yog ntsuas qhov ntsuas kub. Nws muaj ob qhov sib txawv ntawm cov hlau hlau sib txuas ua ke los ua ib qho kev sib tshuam. Thaum qhov sib txuas yog cua sov lossis txias, qhov hluav taws xob me me yog tsim nyob rau hauv hluav taws xob hluav taws xob ntawm lub thermocouple uas tuaj yeem ntsuas tau, thiab qhov no sib haum rau qhov kub thiab txias.
Peb lub ntsiab lus tseem ceeb yog dab tsi uas tswj kev ua haujlwm ntawm thermocouple?
Thermocouples ua haujlwm los ntawm kev siv the Seebeck, Peltier thiab Thomson teebmeem. Cov nyhuv Seebeck tau hais tias thaum ob qhov tsis zoo li cov hlau tau koom nrog ntawm cov kev sib tshuam no, cov hluav taws xob hluav taws xob tsim tawm (uas txawv rau cov hlau sib txawv).
Lub hauv paus ntsiab lus ntawm thermal sensor yog dab tsi?
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm qhov ntsuas kub yog qhov hluav taws xob hla lub diode terminals. Yog hais tias qhov voltage nce, qhov kub thiab txias kuj nce, ua raws li los ntawm ib tug voltage poob ntawm lub transistor terminals ntawm lub hauv paus thiab emitter nyob rau hauv ib tug diode.
Thermocouple siv rau dab tsi?
A Thermocouple yog lub ntsuas ntsuas siv ntsuas kub. Thermocouples muaj ob txoj hlua hlau ua los ntawm cov hlau sib txawv. Covhlau ob txhais ceg yog welded ua ke ntawm ib kawg, tsim ib qho kev sib tshuam. Qhov kev sib tshuam no yog qhov ntsuas qhov ntsuas kub.
