Menene hanyoyin sarrafawa na thermostat?
Akwai manyan hanyoyin sarrafawa guda biyu na ma'aunin zafi da sanyio: Ikon ON/KASHE da sarrafa PID.
1.ON / KASHE iko shine yanayin sarrafawa mai sauƙi, wanda ke da jihohi biyu kawai: ON da KASHE. Lokacin da yanayin zafin da aka saita ya kasance ƙasa da zafin da aka yi niyya, ma'aunin zafi da sanyio zai fitar da siginar ON don fara dumama; Lokacin da aka saita zafin jiki ya fi zafin da aka yi niyya, ma'aunin zafi da sanyio zai fitar da siginar KASHE don dakatar da dumama. Kodayake wannan hanyar sarrafawa yana da sauƙi, zafin jiki zai canza a kusa da ƙimar manufa kuma ba za a iya daidaita shi a ƙimar da aka saita ba. Sabili da haka, ya dace da lokuta inda ba a buƙatar daidaiton sarrafawa ba.
2.PID iko shine mafi ci gaba da sarrafawa hanya. Yana haɗuwa da fa'idodin sarrafawa na daidaitawa, kulawar haɗin kai da kulawa daban-daban, da daidaitawa da ingantawa bisa ga ainihin bukatun. Ta hanyar haɗa madaidaicin, haɗin kai, da sarrafawa daban-daban, masu kula da PID na iya ba da amsa da sauri ga canje-canjen zafin jiki, daidaitawa ta atomatik don ƙetare, da samar da ingantaccen aiki mai ƙarfi. Sabili da haka, an yi amfani da kulawar PID sosai a yawancin tsarin sarrafa masana'antu.
Akwai hanyoyi da yawa don fitar da ma'aunin zafi da sanyio, galibi ya danganta da yanayin sarrafa shi da halayen kayan sarrafawa da ake so. Waɗannan su ne wasu hanyoyin fitarwa na thermostat da aka saba amfani da su:
Ƙarfin wutar lantarki: Wannan hanya ce ta gama gari don sarrafa yanayin aiki na na'urar ta hanyar daidaita girman siginar wutar lantarki. Gabaɗaya, 0V yana nuna cewa an kashe siginar sarrafawa, yayin da 10V ko 5V ke nuna cewa an kunna siginar sarrafawa gabaɗaya, lokacin da na'urar sarrafawa ta fara aiki. Wannan yanayin fitarwa ya dace don sarrafa injuna, magoya baya, fitilu da sauran na'urori waɗanda ke buƙatar sarrafawa mai ci gaba.
Fitowar fitarwa: Ta hanyar kunnawa da kashe siginar kunnawa zuwa sarrafa zafin jiki na fitarwa. Ana amfani da wannan hanya sau da yawa don sarrafa kai tsaye na lodin da bai kai 5A ba, ko kuma sarrafa masu tuntuɓar masu tuntuɓar juna da tsaka-tsaki, da kuma sarrafa iko na waje mai ƙarfi ta hanyar masu tuntuɓar juna.
M jihar gudun ba da sanda direban ƙarfin lantarki fitarwa: Fitar da m jihar gudun ba da sanda fitarwa ta fitarwa ƙarfin lantarki siginar.
M jihar gudun ba da sanda mai ƙarfi yana fitar da ƙarfin lantarki.
Bugu da kari, akwai wasu hanyoyin fitarwa, irin su thyristor lokaci motsi jawo iko fitarwa, thyristor sifili fitarwa da ci gaba da ƙarfin lantarki ko halin yanzu fitarwa sigina. Waɗannan hanyoyin fitarwa sun dace da yanayin sarrafawa daban-daban da buƙatun na'urar.
