Ma thermocouple ndi amodzi mwa mitundu yodziwika bwino ya zoyezera kutentha padziko lonse lapansi. Ndi otchuka m'magawo osiyanasiyana chifukwa cha kusawononga ndalama, kulimba komanso kusinthasintha kwawo. Kugwiritsa ntchito ma thermocouple kumayambira pa zinthu zadothi, mpweya, mafuta, zitsulo, galasi ndi pulasitiki mpaka zakudya ndi zakumwa.
Mukhoza kuzigwiritsa ntchito kulikonse kuti muyang'anire kapena kulemba deta yokhudza kutentha molondola. Ma thermocouple amadziwika kuti amapanga miyeso ya kutentha mwachangu komanso kukana bwino kugwedezeka, kugwedezeka komanso kutentha kwambiri.
Thermocouple ndi sensa yomwe imagwiritsidwa ntchito poyesa kutentha mu sayansi, kupanga, ndi ukadaulo. Imapangidwa polumikiza mawaya awiri osiyana achitsulo kuti apange malo olumikizirana. Malo olumikiziranawo amapanga magetsi odziwikiratu pa kutentha komwe kwaperekedwa. Ma thermocouple nthawi zambiri amagwiritsa ntchito Seebeck kapena thermoelectric effect kuti asinthe magetsi kukhala muyeso wa kutentha.
Ma thermocouple amagwiritsidwa ntchito kwambiri mumakampani azakudya ndi zakumwa monga kupha tizilombo toyambitsa matenda, kuziziritsa, kuwiritsa, kupanga mowa ndi kuyika m'mabotolo. Simuyenera kuda nkhawa mukamagwiritsa ntchito thermocouple temperature gauge chifukwa imapereka mawerengedwe olondola a kutentha kwa kukazinga ndi kuphika kuti chakudya chanu chikhale chophikidwa bwino.
Ma thermocouple nthawi zambiri amagwiritsidwa ntchito m'zida zamalesitilanti monga ma grill, ma toaster, ma deep fryer, ma heater, ndi ma uvuni. Kuphatikiza apo, mutha kupeza ma thermocouple mu mawonekedwe a masensa otenthetsera m'zida za kukhitchini zomwe zimagwiritsidwa ntchito m'mafakitale akuluakulu opangira chakudya.
Ma thermocouple amagwiritsidwanso ntchito m'mafakitale opangira mowa chifukwa kupanga mowa kumafuna kutentha koyenera kuti uwiritse bwino komanso kupewa kuipitsidwa ndi tizilombo toyambitsa matenda.
Kuyeza kutentha kolondola kwa zitsulo zosungunuka monga chitsulo, zinki ndi aluminiyamu kungakhale kovuta chifukwa cha kutentha kwambiri. Zoyezera kutentha zomwe zimagwiritsidwa ntchito kwambiri mu zitsulo zosungunuka ndi platinum thermocouples mitundu B, S ndi R ndi base metal thermocouples mitundu K ndi N. Kusankha mtundu woyenera kudzadalira kutentha komwe kumagwiritsidwa ntchito ndi chitsulocho.
Ma thermocouple achitsulo choyambira nthawi zambiri amagwiritsa ntchito waya wa US No. 8 kapena No. 14 (AWG) wokhala ndi chubu choteteza chitsulo ndi choteteza cha ceramic. Koma ma thermocouple a platinum nthawi zambiri amagwiritsa ntchito mainchesi #20 mpaka #30 AWG.
Kupanga zinthu zapulasitiki kumafuna kuwongolera kutentha bwino. Ma thermocouple nthawi zambiri amafunika kuti azilamulira kutentha m'malo osiyanasiyana opangira mapulasitiki. Amagwiritsidwa ntchito poyesa kutentha kwa kusungunuka kapena pamwamba pa zinthu zopangidwa ndi mapulasitiki ndi zinthu zopangidwa ndi mapulasitiki.
Musanagwiritse ntchito ma thermocouple pokonza mapulasitiki, muyenera kudziwa kuti pali mitundu iwiri ya ma thermocouple mumakampani opanga mapulasitiki. Gulu loyamba limaphatikizapo miyeso. Pano, ma thermocouple angagwiritsidwe ntchito kudziwa ntchito yotumizira kutentha kwa mapulasitiki kutengera gawo lawo. Kumbukirani kuti thermocouple iyenera kuzindikira kusiyana kwa mphamvu yogwiritsidwa ntchito, makamaka chifukwa cha liwiro lake ndi komwe ikupita.
Mungagwiritsenso ntchito ma thermocouple popanga zinthu mumakampani opanga mapulasitiki. Chifukwa chake, mtundu wachiwiri wa kugwiritsa ntchito ma thermocouple mumakampani opanga mapulasitiki umaphatikizapo kupanga zinthu ndi uinjiniya. Pakupanga zinthu, muyenera kugwiritsa ntchito ma thermocouple kuti muwerengere kusintha kwa kutentha kwa zinthu, makamaka pa moyo wa chinthu.
Mainjiniya amatha kusankha ma thermocouple omwe ali oyenera zipangizo zomwe amagwiritsa ntchito popanga zinthu zawo. Mofananamo, angagwiritse ntchito ma thermocouple kuti ayesere momwe kapangidwe kake kamagwirira ntchito. Izi zidzawathandiza kusintha zinthu zisanayambe kupanga.
Mikhalidwe ya ng'anjo nthawi zambiri imasankha thermocouple yoyenera ya ng'anjo ya labotale yotentha kwambiri. Chifukwa chake, kuti musankhe thermocouple yabwino kwambiri, zinthu zingapo ziyenera kuganiziridwa, monga:
Nthawi zambiri, ma extruder amafunika kuthamanga kwambiri komanso kutentha kwambiri. Ma thermocouple a ma extruder amakhala ndi ma adapter a ulusi omwe amathandiza kuyika nsonga zawo za probe mu pulasitiki wosungunuka, nthawi zambiri pansi pa kuthamanga kwambiri.
Mukhoza kupanga ma thermocouple awa ngati zinthu ziwiri kapena zitatu zokhala ndi ulusi wapadera. Ma thermocouple a Bayonet (BT) ndi ma compression thermocouple (CF) amagwiritsidwa ntchito kwambiri muzinthu zotulutsa mpweya zochepa.
Mitundu yosiyanasiyana ya ma thermocouple imagwiritsidwa ntchito m'mafakitale osiyanasiyana. Chifukwa chake ngati mumagwira ntchito mu uinjiniya, zitsulo, chakudya ndi zakumwa, kapena kukonza mapulasitiki, mupeza kuti ma thermocouple amagwiritsidwa ntchito kwambiri poyesa kutentha ndi kuwongolera.
