Munyika yakaoma yekuyera tembiricha,waya dzethermocouplevanoshanda semagamba asina kurumbidzwa, zvichiita kuti vagone kuverenga tembiricha nemazvo uye zvakavimbika mumaindasitiri akasiyana-siyana. Pakati pekushanda kwavo pane chinhu chakakosha—kodhi yeruvara rwewaya yethermocouple. Asi kodhi yeruvara iyi chii chaizvo, uye nei ichikosha?
Kodhi yeruvara yewaya yethermocouple sisitimu yakarongeka zvakanyatsonaka yakagadzirirwa kusiyanisa mhando dzakasiyana dzethermocouples. Rudzi rwega rwega rwethermocouple runoumbwa nemusanganiswa wakasiyana wesimbi, izvo zvinogadzira voltage chaiyo inoenderana netembiricha yakati. Sisitimu iyi yekunyora mavara inoshanda semutauro wepasi rose kune mainjiniya nemainjiniya, zvichivabvumira kuziva nekukurumidza mhando yewaya yethermocouple yavari kubata. Nekuona kubatana kwakakodzera zvichibva pakodhi yeruvara, inovimbisa kuverenga tembiricha kwakavimbika, kudzivirira zvikanganiso zvinodhura uye nguva yekuzorora.
Ngatinyatsoongororai mamwe marudzi ethermocouple akajairika uye makodhi emavara anoenderana nawo. Waya yeType J thermocouple, ine iron positive leg yayo uye constantan negative leg, inoonekwa zviri nyore nehurongwa hwayo hwekunyora mavara. Waya yakanaka ine mavara machena, nepo waya negative iri tsvuku. Rudzi urwu runowanzo shandiswa mumashandisirwo akadai semaovheni emaindasitiri nemaovheni, uko inogona kutsungirira tembiricha yakakwira uye kupa kuverenga kwakarurama.
Rudzi K, zvichida ndiyo thermocouple inonyanya kushandiswa mazuva ano, ine gumbo rechromel positive negumbo realumel negative. Waya yerudzi rweK ine ruvara rweyero, uye waya yenegative yakatsvuka. Inozivikanwa nekusiyana kwayo kwekupisa uye kugadzikana kwakanaka, ma thermocouple erudzi rweK anowanzo shandiswa mumaindasitiri akasiyana-siyana, anosanganisira kugadzira simbi, kugadzira magetsi, uye kugadzira makemikari.
KuneWaya ye thermocouple yerudzi rwe T, ine gumbo remhangura rine positive negumbo risingaperi, waya iri positive ibhuruu, uye waya iri positive itsvuku. Rudzi urwu rwakakodzera kushandiswa pakupisa kwakaderera, senge mufiriji uye kutarisa nharaunda, nekuda kwekururama kwayo kwakanyanya mukupisa kwakaderera.
KuTankii, tinodada nekuzvipira kwedu kuita zvakanaka kana zvasvika pakugadzira waya dzethermocouple. Waya dzedu dzethermocouple dzinotevedzera mitemo yepasi rose yemavara, zvichiita kuti dzienderane zvakanaka nehurongwa hwekuyera huripo pasi rese. Izvi hazvingorerutsi maitiro ekuisa chete asiwo zvinoderedza zvakanyanya njodzi yekusabatanidzwa.
Waya dzedu dzethermocouple dzemhando yepamusoro dzakagadzirwa nemazvo dzichishandisa zvinhu zvepamusoro-soro, dzinopa mashandiro asina muganho. Dzakagadzirwa kuti dzipe zviyero zvekupisa zvakarurama uye zvakagadzikana mumhando dzakasiyana-siyana dzemashandisirwo. Ungave uri kushanda munzvimbo dzinoda kugadzirwa kwemaindasitiri, zvinodiwa chaizvo pakugadzira chikafu, kana kuti munzvimbo dzakanyanya hunyanzvi hwesainzi, mhando dzakasiyana dzezvigadzirwa zvedu zvethermocouple wire zvinokubatsira. Chigadzirwa chega chega chinonyatsozivikanwa nemakodhi emavara akajairwa, zvichibvumira kuzivikanwa nekukurumidza uye nyore, kuitira kuti uve nechivimbo chakazara mukururama kwemabasa ako ekuona tembiricha.
Mukupedzisa, kodhi yeruvara rwewaya yethermocouple haisi kungoratidza chete; chinhu chakakosha mukuyera tembiricha. Nezvigadzirwa zvedu zvewaya yethermocouple yakavimbika uye inoshanda zvakanyanya, unogona kuva nechokwadi chekuti mabasa ako ekutarisa tembiricha achaitwa nemazvo uye nemazvo, zvichikupa simba rekuita sarudzo dzakangwara uye kuchengetedza mabasa ako achifamba zvakanaka.
