Thermocouple, tseem hu ua thermal junction, tus pas ntsuas kub hluav taws xob, lossis lub ntsuas kub, lub ntsuas kub ntsuas muaj ob lub xov hlau sib txawv ntawm txhua qhov kawg. Ib qho kev sib txuas yog muab tso rau qhov chaw ntsuas kub, thiab lwm qhov yog khaws cia ntawm qhov ntsuas kub tsis tu ncua.
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. Cov hlau 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.
Cov piv txwv ntawm cov thermocouples yog dab tsi?
Thermocouples yog siv rau hauv cov ntawv thov uas muaj xws li khoom siv hauv tsevmus rau cov txheej txheem kev lag luam, mus rau hluav taws xob tsim hluav taws xob, rau qhov cub saib xyuas thiab tswj, rau kev ua zaub mov thiab dej haus, mus rau tsheb sensors, mus rau aircraft xyaw, foob pob ua ntxaij, satellites thiab spacecraft.
Dab tsi yog qhov kev ua haujlwm ntawm lub thermocouple?
Thermocouple txoj haujlwm ua haujlwm yog raws li Seeback Effect. Cov txiaj ntsig no tau hais tias thaumkaw lub voj voog yog tsim los ntawm kev sib koom ua ke ntawm ob qhov sib txawv ntawm ob qhov kev sib tshuam, thiab cov kev sib txuas tau khaws cia ntawm qhov kub sib txawv ces qhov hluav taws xob hluav taws xob (e.m.f.) raug cuam tshuam rau hauv lub kaw lus kaw no.
Puas yog thermocouples AC lossis DC?
Ua lub ntsuas cua kub ib qho DC teeb liab, tshem tawm AC suab nrovlos ntawm kev lim dej yog qhov zoo; Ntxiv mus, cov thermocouples tsim hluav taws xob ntawm ob peb kaum ntawm mV thiab vim li no yuav tsum tau ua kom muaj suab nrov.
