Thermocouples ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri pazidziwitso za kutentha padziko lonse lapansi. Iwo ndi otchuka m'madera osiyanasiyana chifukwa cha chuma chawo, kulimba komanso kusinthasintha. Thermocouple ntchito zimachokera ku ceramics, gasi, mafuta, zitsulo, galasi ndi mapulasitiki kupita ku zakudya ndi zakumwa.
Mutha kuzigwiritsa ntchito kulikonse kuti muwunikire molondola kapena kujambula kutentha kwa data. Ma Thermocouples amadziwika popanga miyeso ya kutentha ndikuyankha mwachangu komanso kukana kugwedezeka, kugwedezeka komanso kutentha kwambiri.
Thermocouple ndi sensa yomwe imagwiritsidwa ntchito kuyeza kutentha mu sayansi, kupanga, ndi ntchito zamakono. Zimapangidwa polumikiza mawaya achitsulo awiri osiyana kuti apange mphambano. Kuphatikizikako kumapanga mphamvu yodziwikiratu pa kutentha komwe kwaperekedwa. Ma thermocouples amagwiritsa ntchito Seebeck kapena thermoelectric effect kuti asinthe magetsi kukhala muyeso wa kutentha.
Ma Thermocouples ali ndi ntchito zambiri m'makampani azakudya ndi zakumwa monga pasteurization, refrigeration, fermentation, mowa ndi kubotolo. Simuyenera kuda nkhawa mukamagwiritsa ntchito choyezera kutentha kwa thermocouple chifukwa chimapereka kuzizira kolondola komanso kuwerengera kutentha kuti muwonetsetse kuti chakudya chanu chaphikidwa.
Ma thermocouples nthawi zambiri amagwiritsidwa ntchito m'zida zodyeramo monga ma grill, toaster, zokazinga zakuya, zotenthetsera, ndi uvuni. Kuphatikiza apo, mutha kupeza ma thermocouples mu mawonekedwe a masensa a kutentha mu zida zakukhitchini zomwe zimagwiritsidwa ntchito m'mafakitale akuluakulu opangira chakudya.
Ma thermocouples amagwiritsidwanso ntchito m'malo opangira mowa chifukwa kupanga moŵa kumafunikira kutentha koyenera kuti muyetsetse bwino komanso kupewa kuipitsidwa ndi tizilombo tating'onoting'ono.
Kuyeza molondola kwa kutentha kwazitsulo zosungunuka monga chitsulo, zinki ndi aluminiyamu kungakhale kovuta chifukwa cha kutentha kwambiri. Masensa otentha omwe amagwiritsidwa ntchito kwambiri muzitsulo zosungunula ndi platinamu thermocouples mitundu B, S ndi R ndi maziko azitsulo thermocouples mitundu K ndi N. Kusankha kwa mtundu woyenera kudzadalira kutentha kwa ntchito yeniyeni yokhudzana ndi zitsulo.
Ma thermocouples oyambira zitsulo amagwiritsa ntchito waya woyezera waya wa US No. 8 kapena No. 14 (AWG) wokhala ndi chubu chachitsulo chotchinga ndi chotchingira cha ceramic. Komano, ma thermocouples a platinamu nthawi zambiri amagwiritsa ntchito #20 mpaka #30 AWG diameter.
Kupanga zinthu zapulasitiki kumafuna kuwongolera bwino kutentha. Ma thermocouples nthawi zambiri amafunikira pakuwongolera kutentha m'malo osiyanasiyana opangira mapulasitiki. Amagwiritsidwa ntchito kuyeza kusungunuka kapena kutentha kwa pamwamba mu nkhungu za jakisoni ndi jekeseni.
Musanagwiritse ntchito thermocouples pokonza mapulasitiki, muyenera kudziwa kuti pali mitundu iwiri ya ma thermocouples mumakampani apulasitiki. Gulu loyamba limaphatikizapo miyeso. Apa, ma thermocouples angagwiritsidwe ntchito kudziwa ntchito yotengera kutentha kwa mapulasitiki kutengera gawo lawo. Kumbukirani kuti thermocouple iyenera kuzindikira kusiyana kwa mphamvu yogwiritsidwa ntchito, makamaka chifukwa cha liwiro lake ndi momwe akulowera.
Mutha kugwiritsanso ntchito ma thermocouples pakukula kwazinthu mumakampani apulasitiki. Chifukwa chake, mtundu wachiwiri wogwiritsa ntchito ma thermocouples mumakampani apulasitiki umakhudza kapangidwe kazinthu ndi uinjiniya. Pachitukuko cha zinthu, muyenera kugwiritsa ntchito ma thermocouples kuwerengera kutentha kwa zinthu, makamaka pa moyo wa chinthu.
Akatswiri amatha kusankha ma thermocouples omwe ali oyenera pazinthu zomwe amagwiritsa ntchito popanga zinthu zawo. Momwemonso, amatha kugwiritsa ntchito ma thermocouples kuyesa momwe kapangidwe kake kamagwirira ntchito. Izi zidzawalola kuti asinthe ntchito yopangira isanayambe.
Mng'anjo za ng'anjo makamaka zimatsimikizira thermocouple yoyenera ya ng'anjo ya labotale yotentha kwambiri. Chifukwa chake, kuti musankhe thermocouple yabwino, zinthu zingapo ziyenera kuganiziridwa, monga:
Nthawi zambiri, extruders amafuna kuthamanga ndi kutentha kwambiri. Ma thermocouples a extruder ali ndi ma adapter omwe amawathandizira kuyika malangizo awo mupulasitiki wosungunuka, nthawi zambiri amakhala pansi.
Mutha kupanga ma thermocouples ngati chinthu chimodzi kapena ziwiri zokhala ndi ulusi wapadera. Bayonet thermocouples (BT) ndi compression thermocouples (CF) amagwiritsidwa ntchito kwambiri pazigawo zotsika zotulutsa mpweya.
Mitundu yosiyanasiyana ya ma thermocouples imakhala ndi ntchito zambiri m'mafakitale osiyanasiyana. Chifukwa chake ngati mumagwira ntchito mu uinjiniya, zitsulo, chakudya ndi zakumwa, kapena kukonza mapulasitiki, mupeza kuti ma thermocouples amagwiritsidwa ntchito kwambiri poyezera kutentha ndi kuwongolera.
