Chifukwa chiyani thermocouple imafunikira chipukuta misozi yozizira?

ThMa ermocouples amagwiritsidwa ntchito kwambiri ngati zinthu zowunikira kutentha m'mafakitale ndi sayansi chifukwa cha kulimba kwawo, kutentha kwakukulu, komanso nthawi yoyankha mwachangu. Komabe, vuto lomwe limakhalapo ndi ma thermocouples ndilofunika kubweza kozizira. Thermocoupleimapanga mphamvu yamagetsi molingana ndi kusiyana kwa kutentha pakati pa mapeto ake (mapeto otentha) ndi mapeto ake (mapeto ozizira). Mphambano wolumikizira nthawi zambiri umakhala pamalo olowera pachida choyezera, ndipo kutentha kwake kumatha kusinthasintha chifukwa cha chilengedwe. Kusintha kumeneku kwa kutentha kwapakati kozizira kungayambitse zolakwika za kuyeza kwa kutentha.

Cold mphambano chipukuta misozi ndi ndondomeko kuyeza molondola kutentha mphambano ndi kubweza zotsatira zake pa linanena bungwe thermocouple voteji. Izi ndizofunikira kwambiri kuti muthe kuyeza kutentha kolondola, makamaka pamapulogalamu omwe amafunikira kuwongolera bwino kutentha. Kukhazikitsa chipukuta misozi chozizira ndikofunikira kuti muwonetsetse kulondola komanso kudalirika kwa kuyeza kwa kutentha kwa thermocouple. Popanda kulipidwa koyenera, zolakwika zazikulu zimatha kuchitika pakuwerengera kutentha, makamaka m'malo okhala ndi kuzizira kosakhazikika.

Pali njira zingapo zopezera chipukuta misozi chozizira, njira imodzi yodziwika bwino ndikugwiritsa ntchito chowongolera chizindikiro cha thermocouple. Zidazi zidapangidwa kuti zizitha kuyeza kutentha kwa mphambano yozizira ndikupereka chipukuta misozi chofunikira pakutulutsa kwamagetsi a thermocouple. Zowongolera ma Signal zitha kukhazikitsidwa ngati mayunitsi oyimirira okha kapena ophatikizidwa mu zida zoyezera. Kusintha kwa ma sign pafupi ndi mphambano yozizira kungagwiritsidwe ntchito kuchepetsa zolakwika pamiyezo ya kutentha kuphatikiza kugwiritsa ntchito chowongolera chodzipatulira. Pogwiritsa ntchito njira zoyenera zosefera ndi kukulitsa pafupi ndi mphambano yozizira, mphamvu yamagetsi ya thermocouple imatha kusinthidwa kuti muchepetse kusintha kwa kutentha kwa mphambano yozizira.

Shanghai Wangyuan Instruments of Measurement Co., Ltd. ndi Chinese mkulu-chatekinoloje ogwira ntchito mlingo kampani okhazikika mu mafakitale ndondomeko ulamuliro luso ndi mankhwala kwa zaka zoposa 20. Titha kupereka zolondola komanso zodalirikazotumizira kutenthandi zomverera zinthu za mphambano ozizira kulipidwa thermocouple komansowanzeru chitetezo chotchingandi automatic cold junction compensation function. Khalani omasuka kulankhula nafe kuti mudziwe zambiri.
