M'dziko lovuta la kuyeza kutentha,mawaya a thermocoupleamagwira ntchito ngati ngwazi zosasimbika, zomwe zimathandizira kuwerengera kolondola komanso kodalirika kwa kutentha m'mafakitale ambiri. Pakatikati pa magwiridwe antchito ake pali chinthu chofunikira kwambiri - mtundu wa waya wa thermocouple. Koma kodi mtundu umenewu ndi wotani, ndipo n’chifukwa chiyani uli wofunika?
Khodi yamtundu wa waya wa thermocouple ndi dongosolo lokhazikika bwino lomwe limapangidwira kusiyanitsa mitundu yosiyanasiyana ya ma thermocouples. Mtundu uliwonse wa thermocouple umapangidwa ndi kuphatikiza kwapadera kwazitsulo, zomwe zimapanga mphamvu yamagetsi yeniyeni yolingana ndi kutentha kwina. Dongosolo lamtundu uwu limagwira ntchito ngati chilankhulo chapadziko lonse lapansi kwa akatswiri ndi mainjiniya, kuwalola kuzindikira mwachangu mtundu wa waya wa thermocouple womwe akugwira. Poonetsetsa kugwirizana koyenera kutengera mtundu wamtundu, kumatsimikizira kuwerengera kodalirika kwa kutentha, kuteteza zolakwika zamtengo wapatali ndi nthawi yopuma.
Tiyeni tifufuze mozama za mitundu yodziwika bwino ya thermocouple ndi mitundu yawo yofananira. Waya wamtundu wa J thermocouple, wokhala ndi mwendo wake wachitsulo komanso mwendo wopanda pake, umadziwika mosavuta ndi mtundu wake - coding scheme. Waya wabwino ndi woyera, pomwe waya wopanda pake ndi wofiira. Mtundu uwu umagwiritsidwa ntchito nthawi zambiri pa ntchito monga ng'anjo za mafakitale ndi mauvuni, kumene umatha kupirira kutentha kwakukulu ndi kupereka zowerengera zolondola.
Mtundu K, mwinamwake thermocouple yofala kwambiri yomwe ikugwiritsidwa ntchito masiku ano, imakhala ndi mwendo wabwino wa chromel ndi mwendo woipa wa alumel. Waya wabwino wamtundu wa K ndi wachikasu, ndipo waya woyipa ndi wofiira. Odziwika chifukwa cha kutentha kwake kwakukulu komanso kukhazikika bwino, ma thermocouples a Type K amagwiritsidwa ntchito nthawi zambiri m'mafakitale osiyanasiyana, kuphatikiza zitsulo, kupanga magetsi, ndi kukonza mankhwala.
Za kuType T thermocouple waya, yomwe imakhala ndi mwendo wabwino wamkuwa ndi mwendo wolakwika wa constantan, waya wabwino ndi buluu, ndipo waya woipa ndi wofiira. Mtundu uwu ndi woyenerera bwino ntchito zochepetsera kutentha, monga m'makina a firiji ndi kuyang'anira chilengedwe, chifukwa cha kulondola kwake kwapamwamba pa kutentha kwapansi.
Ku Tankii, timanyadira kudzipereka kwathu kuchita bwino pankhani yawaya wa thermocouple. Mawaya athu a thermocouple amatsatira mosamalitsa miyezo yapadziko lonse lapansi - yokhotakhota, kuwonetsetsa kuti ikugwirizana mosasunthika ndi machitidwe omwe alipo padziko lonse lapansi. Izi sizimangofewetsa njira yoyika komanso zimachepetsa kwambiri chiopsezo cha kusokonekera.
Wopangidwa mwatsatanetsatane pogwiritsa ntchito zida zapamwamba, mawaya athu apamwamba kwambiri a thermocouple amapereka magwiridwe antchito osayerekezeka. Amapangidwa kuti azipereka miyeso yolondola komanso yokhazikika ya kutentha m'mapulogalamu osiyanasiyana. Kaya mukugwira ntchito m'malo ovuta kupanga mafakitale, zofunikira zenizeni pakukonza chakudya, kapena gawo lapadera la kafukufuku wasayansi, mitundu yathu yosiyanasiyana yamawaya a thermocouple yakuphimbani. Chilichonse chimadziwika bwino ndi ma code amtundu wamba, omwe amalola kuti adziwike mwachangu komanso mosavuta, kotero mutha kukhala ndi chidaliro chonse pakulondola kwa kutentha kwanu - ntchito zozindikira.
Pomaliza, khodi yamtundu wa waya wa thermocouple ndi yochulukirapo kuposa chizindikiro chowoneka; ndi gawo lofunikira kwambiri pakuyeza kutentha. Ndi zida zathu zamawaya odalirika komanso apamwamba kwambiri a thermocouple, mutha kukhala otsimikiza kuti ntchito zanu zowunikira kutentha zidzachitidwa mwatsatanetsatane komanso moyenera, kukupatsani mphamvu zopanga zisankho mwanzeru ndikupangitsa kuti ntchito zanu ziziyenda bwino.
