K-Type Thermometers Thermocouples

Masensa a kutentha kwa Thermocouple ndi omwe amagwiritsidwa ntchito kwambiri pa kutentha. Izi ndichifukwa choti ma thermocouples ali ndi mawonekedwe okhazikika, kuchuluka kwa kuyeza kutentha, kutumizira ma siginecha mtunda wautali, ndi zina zambiri, ndipo ndizosavuta kupanga komanso zosavuta kugwiritsa ntchito. Ma thermocouples amasintha mphamvu yotentha kukhala ma siginecha amagetsi, kupanga mawonetsedwe, kujambula, ndi kufalitsa mosavuta.

Mfundo Yogwira Ntchito ya Thermometers Thermocouples

Dera lotsekedwa lopangidwa ndi ma conductor awiri azinthu zosiyanasiyana. Pakakhala kutentha kwa dera lonselo, madzi amayenda mozungulira. Panthawiyi, kaya pali mphamvu yamagetsi yamagetsi-thermoelectric pakati pa mapeto awiri a chitukuko, izi ndi zomwe timatcha kuti Seebeck effect.

The homogeneous conductors wa zigawo ziwiri zosiyana ndi maelekitirodi otentha, kutentha kwapamwamba mapeto ndi mapeto a ntchito, otsika kutentha mapeto ndi ufulu mapeto, ndipo mapeto aulere nthawi zambiri mu chikhalidwe kutentha nthawi zonse. Malinga ndi ubale pakati pa kuthekera kwa thermoelectric ndi kutentha, pangani tebulo lolozera la thermocouple; tebulo lolozera ndi tebulo lolozera lomwe kutentha kwake kwaulele ndi 0 ° C ndi zochitika zosiyanasiyana za thermoelectric nthawi zina zimawonekera mosiyana.

Pamene chinthu chachitatu chachitsulo chikugwirizana ndi dera la thermocouple, malinga ngati magawo awiriwa ali pa kutentha komweko, mphamvu ya thermoelectric yopangidwa ndi thermocouple imakhala yofanana, ndiko kuti, sichikhudzidwa ndi chitsulo chachitatu chomwe chimayikidwa mu dera. Choncho, pamene thermocouple ikuyesa kutentha kwa ntchito, imatha kugwirizanitsidwa ndi chida choyezera luso, ndipo mutatha kuyeza mphamvu ya thermoelectric, kutentha kwa sing'anga yoyezera kumatha kudziwidwa palokha.
