Ma thermocouple amagwiritsidwa ntchito m'mafakitale osiyanasiyana poyesa ndi kuwongolera kutentha. Komabe, kulondola ndi kudalirika kwa thermocouple sikudalira kokha pa sensa yokha, komanso pa chingwe chomwe chimagwiritsidwa ntchito kulumikiza ku chida choyezera. Mitundu iwiri yodziwika bwino ya zingwe zomwe zimagwiritsidwa ntchito pa ma thermocouple ndi zingwe zolipirira ndi zingwe zowonjezera. Ngakhale kuti zingawoneke zofanana, pali kusiyana kwakukulu pakati pa ziwirizi.
Choyamba tiyeni tikambirane za zingwe zolipirira za thermocouple. Zingwe zolipirira zimapangidwa makamaka kuti zilumikize masensa a thermocouple ku chida choyezera, zomwe zimathandizira kusintha kwa kutentha pa kutalika kwa chingwe. Zingwezi zimapangidwa kuchokera ku zinthu zosiyanasiyana zomwe zimatsanzira mphamvu ya thermoelectric ya thermocouple yokha. Izi zimatsimikizira kuti kusintha kulikonse kwa kutentha pa kutalika kwa chingwe sikukhudza kulondola kwa muyeso wa kutentha.
Chinthu chachikulu chomwe chimapangitsa kuti zingwe zolipirira zigwire ntchito ndi kuthekera kwawo kusunga mphamvu ya thermoelectric ya thermocouple yolumikizidwa. Izi zimachitika pogwiritsa ntchito chinthu chomwe chili ndi mphamvu yofanana ya thermoelectric ndi thermocouple, zomwe zimathandiza kuthetsa kusintha kwa mphamvu yamagetsi komwe kumachitika chifukwa cha kutentha kwa chingwecho. Chifukwa chake, zingwe zolipirira zimagwira ntchito bwino poyesa kutentha komwe kumagwiritsidwa ntchito pamene mtunda pakati pa thermocouple ndi chida choyezera ndi wautali kapena komwe kutentha sikufanana.
Zingwe zowonjezera za ThermocoupleKumbali ina, amagwiritsidwa ntchito kukulitsa kufikira kwa thermocouple popanda kusokoneza kulondola kwa muyeso wa kutentha. Mosiyana ndi zingwe zolipirira, zingwe zowonjezera sizimatsanzira mphamvu ya thermocouple ya thermoelectric. M'malo mwake, zimapangidwa kuchokera ku chinthu chomwecho mongamawaya a thermocouple, kuonetsetsa kuti chizindikiro cha magetsi chomwe chimapangidwa ndi thermocouple chimatumizidwa molondola pamtunda wautali. Ntchito yayikulu ya zingwe zokulitsa ndikusunga umphumphu wa chizindikiro cha magetsi chomwe chimapangidwa ndi thermocouple, zomwe zimathandiza kuti chitumizidwe pamtunda wautali popanda kutayika kapena kusokonekera. Izi ndizofunikira kwambiri m'malo opangira mafakitale komwe ma thermocouple amatha kukhala m'malo otentha kwambiri ndipo zida zoyezera zimapezeka m'zipinda zowongolera kapena m'malo akutali.
Kusiyana pakati pa zingwe zolipirira thermocouple ndi zingwe zowonjezera
Kapangidwe ka Thermoelectric: Kusiyana kwakukulu pakati pa mitundu iwiriyi ya zingwe ndi kapangidwe kake ka thermoelectric. Zingwe zolipirira zimapangidwa kuti zitsanzire kapangidwe ka thermoelectric ka thermocouple, pomwe zingwe zowonjezera zimapangidwa kuchokera kuzinthu zomwezo monga mawaya a thermocouple kuti zisunge umphumphu wa chizindikiro cha magetsi.
Kulipira Kutentha: Zingwe zolipirira zimapangidwa mwapadera kuti zigwirizane ndi kusintha kwa kutentha m'litali mwa chingwe kuti zitsimikizire kuti kutentha kumayesedwa molondola. Mosiyana ndi zimenezi, zingwe zokulitsa sizimapereka chiwongola dzanja cha kutentha ndipo zimagwiritsidwa ntchito makamaka kukulitsa kutalika kwa thermocouple.
Kugwiritsa Ntchito Mwachindunji: Zingwe zolipirira ndizofunikira kwambiri pa ntchito zomwe kusintha kwa kutentha m'litali mwa chingwe kungakhudze kulondola kwa muyeso wa kutentha. Koma zingwe zowonjezera zimagwiritsidwa ntchito kutumiza zizindikiro za magetsi pamtunda wautali popanda kutayika kapena kusokonekera.
Momwe mungasankhire chingwe choyenera
Posankha chingwe choyenera kugwiritsa ntchito thermocouple, zofunikira zenizeni za dongosolo loyezera ziyenera kuganiziridwa. Zinthu monga mtunda pakati pa thermocouple ndi chida choyezera, malo otenthetsera komanso kulondola kwa muyeso wa kutentha ndizofunikira kwambiri podziwa kufunikira kwa chingwe cholipirira kapena chowonjezera.
Zingwe zolipirira ndi zabwino kwambiri pamene mtunda pakati pa thermocouple ndi chida choyezera ndi waukulu kapena pamene kutentha sikofanana. Zingwe zimenezi zimaonetsetsa kuti kusintha kwa kutentha m'litali mwa chingwe sikukhudza kulondola kwa muyeso wa kutentha, motero ndizofunikira kuti kutentha kuyende bwino komanso kuyang'aniridwa.
Kumbali inayi, zingwe zokulitsa zimagwiritsidwa ntchito kwambiri ngati thermocouple ikufunika kukhala kutali ndi chida choyezera. Zingwezi zimatha kutumiza molondola chizindikiro cha magetsi chomwe chimapangidwa ndi thermocouple patali, motero kusunga umphumphu wa muyeso wa kutentha.
Ndikofunikira kudziwa kuti kugwiritsa ntchito chingwe cholakwika kungayambitse kuyeza kutentha kolakwika, zomwe zingakhudze ubwino ndi chitetezo cha njira yowunikira. Chifukwa chake, tikukulimbikitsani kuti wogulitsa kapena mainjiniya wodziwa bwino ntchito afunsidwe kuti atsimikizire kuti chingwe choyenera chasankhidwa kuti chigwiritsidwe ntchito pa thermocouple inayake.
Pomaliza, timapereka mitundu yosiyanasiyana yazingwe za thermocouplendi ntchito yokonzedwa mwamakonda, choncho musazengereze kulankhulana nafe ngati mukufuna!
