Kanjani nokuthi yiliphi izinga lokushisa

Ukuqapha ukuguqulwa kwezinkomba zokushisa (ngamanye amagama, i-thermometry) kuyadingeka ekufundweni kwe-laboratory noma yamakhemikhali, ukugcina ubuchwepheshe bezinqubo ekukhiqizeni noma ukuqinisekisa ukuphepha kwemikhiqizo.

Kunengqondo ukucabanga ukuthi ubuchwepheshe obusetshenziselwa ukukhiqiza abufanelekile ngezinhloso zasendlini. Sizokwazi ngokusondelana kakhulu nezinsimbi ezivumela ukufeza izilinganiso ezimweni ezahlukene.

Yiqiniso, amadivaysi avamile kakhulu akuvumela ukuba ulinganise ukushisa yi-thermometers. Lezi zibandakanya imeteorological kanye ne-laboratory, ezokwelapha kanye ne-electrocontact, ezobuchwepheshe kanye ne-manometric, ezikhethekile nokubonisa. Inani eliphelele lokuguqulwa liyizinkulungwane ezimbalwa.

Izindlela namadivayisi wokunquma izinga lokushisa

Ama-thermometer ajwayelekile kithi asengxenye encane yazo zonke amadivaysi noma amadivayisi akhona namuhla, asetshenziselwa izimo lapho izinga lokushisa lidingekile. Ukuzimisela ubukhulu bezinhlanzi ezishisayo kungenziwa ngezindlela eziningana. Isimiso sokusebenza kwedivaysi ngayinye ipharamitha ethile yezinto noma umzimba. Kuncike ebangeni lapho izinga lokushisa kufanele lenziwe khona, kusetshenziswe amadivaysi ahlukene.

• Ukucindezela. Ukushintsha kwalo kukuvumela ukuba uqaphe ukushintsha kwezinga lokushisa kusuka ebangeni -160 kuya ku-60. Amadivayisi abizwa ngokuthi ama-gauge we-pressure.
• Ukumelana kagesi. Yisimiso esiyisisekelo sokusebenza kwe-thermometer kagesi kanye ne-semiconductor yokulinganisa ukulinganisa. Umehluko ekufuneni uvumela amadivayisi we-semiconductor ukuthi alinganise kusuka ku--90 degrees kuya ku-+180. Amadivayisi kagesi akwazi ukulungisa kusuka ku -200 kuya ku-+500 degrees.
• Umphumela we-thermoelectric yiyona impahla ehamba phambili ye-thermocouple eqinisekisiwe noma ekhethekile. Amadivaysi ohlobo olumisiwe anikezela ukuzimisela kwemingcele yokushisa kusuka ku- -50 kuya ku-1600 degrees. Amadivaysi akhethekile aklanyelwe ukusebenza ngokusebenza okubalulekile. Uhlu lwabo lokusebenza luvela ku-+1300 kuya ku-+2500 degrees.
• Ukwanda kokushisa. Isetshenziswe kuma-thermometers ahlanzekile, okuvumela ukucacisa amazinga okushisa aphakathi kuka--190 kuya ku-600.
• Imisebe yelanga. Isekelwe emsebenzini we-pyrometer wezinhlobo ezahlukene. Kuye ngohlobo lwedivayisi, ububanzi bezinga lokushisa nalo liyahlukahluka. Ukuqaphela okukhethekile kufanele kukhokhwe ukuthi lezi zinsiza zifanele kuphela ukulinganisa izinkomba eziphezulu. Ngama-pyrometer ombala, ububanzi bokusebenza bokushisa buyizinombolo ezingu-1400 - 2800. Ngamadivaysi ama-radiation, lezi zibalo zizolingana nama-20 - 3000 degrees. Amadivayisi we-Photovoltaic aloba izinga lokushisa lika-600-4000, namapromrometer obala angalinganisa ukufundwa ku-range kuya kuma-700-6000 degrees.

Ngokwemvelo, lo mbuzo uvela ngokuthi izakhiwo zomzimba zenza kanjani ukukala ukushisa kwemoya noma isensi eshisayo. Emanometers, amandla kagesi noma ukucindezelwa kwamanzi kuthathwa njengesisekelo sombuso othile wokushisa. Ama-Pyrometer nama-imagers ashisayo avumela ukulinganisa izinga lokushisa ebusweni bento, ebona ukukhanya okushisa okuvela kuwo (i-pyrometer ibonisa idatha ngesimo sedijithali, i-imager ezishisayo inikeza "isithombe" sento nokushisa kwayo). Ukusetshenziswa komphumela we-thermoelectric kubandakanya ukwakhiwa kwe-thermocouple. Ngokuvamile, i-thermocouple yisifunda esivaliwe sabaqhubi ababili abahlukene. Umphumela othile wokushisa ubangela ukucindezeleka okuthile. Lesi simiso sisetshenziselwa ukumelana ne-thermometers.

Ngokuvamile, izindlela zokulinganisa izinga lokushisa zingahlukaniswa ngezindlela zokuxhumana nezingaxhumana nabo. Isibonelo esikhulu kunazo zonke sohlelo lokuxhumana yisimiso sezokwelapha, ikhamera ye-thermographic engeyona contact.
