Fotokozani mwatsatanetsatane miyeso ya kutentha kwa thermocouple

Thermocouplendi mtundu wa chinthu chozindikira kutentha, ndi mtundu wa chida, thermocouple imayeza kutentha. Chingwe chotsekedwa chopangidwa ndi oongolera awiri okhala ndi zida zosiyana. Chifukwa cha zinthu zosiyanasiyana, kuchuluka kwama electron kumabweretsa kufalikira kwa ma elekitironi, ndipo kuthekera kumapangidwa pambuyo pofanana. Pakakhala kutentha kwakanthawi kumapeto onse awiri, pakadali pano pakapangidwanso mphamvu, ndipo mphamvu yamagetsi yamagetsi imapangidwa. Kukula kwakusiyana kwakutentha, kwakukulu pakali pano. Mutatha kuyeza mphamvu yamagetsi yamagetsi, phindu la kutentha limatha kudziwika. Mwachizolowezi, thermocouple ndi chosinthira mphamvu chomwe chimasinthira mphamvu yamagetsi yamagetsi yamagetsi.

Ubwino waukadaulo wa magalasi:magalasikukhala ndi miyeso yambiri ya kutentha ndi ntchito yokhazikika; kulondola kwakukulu kwa kuyeza, thermocouple imalumikizana mwachindunji ndi chinthu choyezedwa, ndipo sichimakhudzidwa ndi sing'anga yapakatikati; nthawi yoyankhira kutentha ndi yofulumira, ndipo thermocouple imakhudzidwa ndi kusintha kwa kutentha; Mtundu woyezera ndi waukulu, thermocouple imatha kuyeza kutentha mosalekeza kuchokera ku -40~+1600℃; ndithermocoupleali ndi ntchito zodalirika komanso zabwino zama makina. Moyo wautali ndi kukhazikitsa kosavuta. Banja la galvanic liyenera kukhala lopangidwa ndi zida ziwiri zoyendetsera (kapena semiconductor) zopangidwa mosiyanasiyana koma kukwaniritsa zofunikira zina kuti apange lupu. Payenera kukhala kusiyana kwa kutentha pakati pa malo oyesera ndi malo owunikira a thermocouple.

Otsogolera kapena oyendetsa semiconductors A ndi B a zida ziwiri zosiyana amaphatikizidwa pamodzi kuti apange chitseko chatsekedwa. Pakakhala kusiyana kwakutentha pakati paziphatikizi ziwiri ndi 1 za oyendetsa A ndi B, mphamvu yamagetsi imapangidwa pakati pa awiriwo, ndikupanga mpata waukulu pakatikati. Chodabwitsa ichi chimatchedwa mphamvu yamagetsi. Thermocouples amagwira ntchito pogwiritsa ntchito izi.
