Dab tsi yog thermocouple?
Thermocouples yog cov sensors siv los ntsuas qhov kub thiab txias. Nws yog tsim los ntawm ob txoj hlua hlau sib txawv, uas yog welded ua ke ntawm ib qho taw tes los ua ib qho kev sib koom tes kub, thiab ob qhov kawg yog txuas nrog cov ntsuas kub. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm thermocouples yog raws li cov nyhuv thermoelectric. Thaum cov pob qij txha thiab qhov kub thiab txias ntawm ob hom ntawm cov xov hlau sib txawv, qhov muaj peev xwm sib txawv yuav raug tsim tawm, uas ua rau muaj kev hloov pauv tam sim no.
Yuav ua li cas thermocouples tsim tam sim no thiab voltage?
Thaum ob lub pob qij txha ntawm lub thermocouple sib txawv ntawm qhov kub thiab txias, qhov kub thiab txias yuav tshwm sim ntawm ob lub xov hlau, uas ua rau muaj qhov sib txawv ntawm ob lub pob qij txha. Qhov no yog vim tias cov qauv huab cua hluav taws xob thiab cov yam ntxwv thermal vibration ntawm cov hlau sib txawv ntawm cov xov hlau sib txawv, ua rau cov hluav taws xob mus rau hauv qhov kub thiab txias, ua rau muaj peev xwm sib txawv thiab tsim tam sim no.
Yuav ua li cas yog lub mis rau xam qhov tam sim no thiab voltage ntawm thermocouples?
Cov mis rau xam qhov tam sim no thiab voltage ntawm thermocouples yog: V= * (T2-T1)
Ntawm lawv, V yog qhov tam sim no voltage, Thermoelectric coefficient ntawm lub thermocouple, T2 yog ntsuas qhov ntsuas kub ntawm thermocouple, thiab T1 yog qhov ntsuas kub.
Dab tsi yog chav tsev ntawm thermocouple tam sim no thiab voltage?
Chav tsev ntawm thermocouple tam sim no voltage yog millivolts (mV).
Dab tsi yog txoj kev ntsuas rau thermocouple tam sim no thiab voltage?
Muaj ob txoj hauv kev los ntsuas qhov tam sim no thiab qhov hluav taws xob ntawm cov thermocouples: siv cov cuab yeej thev naus laus zis thev naus laus zis rau kev ntsuas, lossis siv multimeter los ntsuas tus nqi hluav taws xob thiab tom qab ntawd hloov mus rau kev suav.
Dab tsi yog qhov chaw thov ntawm thermocouple tam sim no thiab voltage?
Daim ntawv thov teb ntawm thermocouple tam sim no thiab voltage yog qhov dav heev, thiab cov kev siv feem ntau suav nrog cov ntsuas kub, cov khoom siv kho cua sov, boiler kub tswj, aerospace, thiab lwm yam. Thermocouples tuaj yeem ua haujlwm ruaj khov hauv ntau qhov chaw ib puag ncig, nrog rau qhov zoo xws li kev ntseeg siab thiab tus nqi qis.
