Izindlela zokushisa ezingezinhle zokushisa ezi-coefficient (NTC) zisetshenziswa njengezinto ezisezingeni eliphakeme zokuhlola izinga lokushisa inzwa ezinhlobonhlobo zezinsizakusebenza zezimoto, zezimboni, zendlu kanye nezicelo zezokwelapha. Ngoba izinhlobonhlobo zezinhlobonhlobo ze-NTC zitholakala - zenziwe ngemiklamo ehlukene futhi zenziwe ngezinto ezahlukahlukene - ukukhetha okungcono kakhuluAma-Thermitors we-NTCUkuze uhlelo lokusebenza oluthile lungaba inselelo.
NgobaniqokaNTC?
Kunobuchwepheshe obuthathu bokushisa bensor sensor, ngayinye enezimpawu zayo: izinzwa zokushisa zokushisa (i-RTD) nezinhlobo ezimbili zama-thermitors, ama-thermitors amahle nezingalungile okushisa okushisa. Izinzwa ze-RTD zisetshenziselwa kakhulu ukukala amazinga okushisa ahlukahlukene, futhi ngoba zisebenzisa insimbi emsulwa, zivame ukubiza kakhulu kunama-thermistors.
Ngakho-ke, ngoba ashikubaluleka alinganisa izinga lokushisa ngokunemba okufanayo noma okungcono, ajwayele ukuthandwa ngama-RTD. Njengoba igama lisho, ukumelana kwe-thermistor efanelekile yokushisa i-coeffiently (PTC) i-thermistor iyanda ngokushisa. Zivame ukusetshenziswa njengezinzwa zokushisa ezinomkhawulo we-switch-off noma ukuphepha ngoba ukumelana kukhuphuka uma izinga lokushisa elishintshayo lifinyelelwe. Ngakolunye uhlangothi, njengoba izinga lokushisa lenyuka, ukumelana kwe-thermistor engemihle yokushisa (NTC) kuyancipha. Ukumelana nobudlelwano bokushisa (i-RT) kuyijika elisicaba, ngakho-ke kunembile kakhulu futhi lizinzile ezilinganisweni zokushisa.
Izindlela zokukhetha ezibalulekile
Ama-Thermitors aphezulu we-NTC azwela kakhulu futhi angalinganisa izinga lokushisa elinokunemba okuphezulu (± 0.1 ° C), abenze balungele izinhlelo eziningi. Kodwa-ke, ukukhethwa kwalolu hlobo okufanele uchaze kuncike ekunciphiseni okuningi - uhla lokushisa, ububanzi bokumelana, ukuqinisekiswa kokulinganisa, imvelo, isikhathi sokuphendula kanye nezidingo zesayizi.
Izinto ze-epoxy camera ze-NTC zinamandla futhi zivame ukukala amazinga okushisa phakathi kuka -55 ° C no-155 ° C, ngenkathi ama-Glass-encresed ° Ngezicelo ezidinga izikhathi zokuphendula ezisheshayo, izakhi ezivalelwe ingilazi ziyindlela efanelekile. Futhi zihlangene kakhulu, ngamawazi amancane njenge-0.8mm.
Kubalulekile ukufanisa izinga lokushisa le-NTC Thermistor ekushiseni kwengxenye ebangela ukuthi izinga lokushisa lishintshe. Ngenxa yalokhu, azitholakali kuphela ngesimo sendabuko ezinomkhondiso, kepha futhi zingafakwa kuhlobo lwesikulufa sezindlu ukuze unamathisele kwi-radiator ukuze ufake i-radiator ukuze ukhishwe endaweni efanelekile.
Okusha emakethe kuholelwa ngokuphelele mahhala-mahhala (chip and contonent) NTC Izinkampani ze-NTC ezihlangabezana nezidingo eziqinile zomyalo weRosh2 ozayo.
IsiceloEingxubeOukubuyekeza
Izakhi ze-NTC Sensor kanye nezinhlelo zisetshenziswa ezinhlobonhlobo zamasimu, ikakhulukazi emkhakheni wezimoto. Izicelo ezijwayelekile zifaka amasondo okuqondisa okufudumele kanye nezihlalo, nezinhlelo zokulawula kwesimo sezulu esinezinkulungwane. Ama-thermitors asetshenziswa ezinhlelweni zokuphinda usebenzise igesi (EGR) Ibanga lokushisa elibanzi elibanzi linokumelana nomthelela omkhulu kanye namandla okudlidliza, ukuthembeka okuphezulu, kanye nokuphila okude nokuqina kwesikhathi eside. Uma ngabe ama-thermitors azosetshenziswa ezinhlelweni zezimoto, khona-ke i-AEC-Q200 Global Standard lapha iyimpoqo.
Ezimotweni zikagesi nezi-hybrid, izinzwa ze-NTC zisetshenziselwa ukuphepha kwebhethri, ukuqapha ukugeleza kukagesi kanye nesimo sokushaja. Uhlelo lokupholisa okuqandayo olupholisa ibhethri luxhumeke ohlelweni lokupholisa umoya.
Ukuzwakala kokushisa nokulawula izinto zasendlini kufaka phakathi amazinga okushisa ahlukahlukene. Isibonelo, esomisi somile, ainzwa yokushisaInquma izinga lokushisa komoya oshisayo ogeleza esigukwini kanye nokushisa komoya okugeleza njengoba kuphuma isigubhu. Ngokupholisa nokuqandisa, theInzwa ye-NTCKukala izinga lokushisa egumbini elipholile, kuvimbela i-evaporator ukuthi ingabazi, futhi ithole izinga lokushisa elikhona. Emishini emincane efana nezinsimbi, abenzi bekhofi nama-kettles, izinzwa zokushisa zisetshenziselwa ukuphepha nokusebenza kahle kwamandla. Ukushisa, umoya omncane kanye nomoya wokufaka umoya (HVAC) amayunithi ahlala ingxenye enkulu yemakethe.
Inkambu yezokwelapha ekhulayo
Inkambu ye-Medical Electronics inamadivayisi ahlukahlukene wokunakekelwa kwe-Ipatient, Outpatient kanye nokunakekelwa kwasekhaya. Ama-Thermitors e-NTC asetshenziswa njengezakhi zokuzwa amazinga okushisa kumadivayisi wezokwelapha.
Lapho kukhishwa idivaysi encane yezokwelapha ephathekayo, izinga lokushisa elisebenzayo lebhethri elishajekayo kumele libhekwe njalo. Lokhu kungenxa yokuthi ukusabela kwe-electrochemical okusetshenziswe ngesikhathi sokuqapha kuncike kakhulu lokushisa, ukushesha, ukuhlaziya okunembile kubalulekile.
Ama-patches wokuqapha ama-glucose aqhubekayo (GCM) angabheka amazinga kashukela egazini ezigulini ezinesifo sikashukela. Lapha, inzwa ye-NTC isetshenziselwa ukukala lokushisa, ngoba lokhu kungathinta imiphumela.
Ukwelashwa okuqhubekayo kwe-airway ye-Airway (CPAP) kusebenzisa umshini wokusiza abantu abane-apnea yokulala baphefumula kalula ngesikhathi sokulala. Ngokufanayo, ngezifo ezinzima zokuphefumula, ezifana ne-Covil-19, ama-mende anjiniyela emishini athatha ukuphefumula kwesiguli ngokucindezela umoya ngobumnene emaphashini abo futhi kususwe i-carbon dioxide yawo. Ezimweni zombili, izinzwa ezivalekile ze-NTC zihlanganiswe emgodini, i-catheter yase-airway kanye nomlomo wokudla ukukala izinga lokushisa komoya ukuze uqinisekise ukuthi iziguli zihlala zikhululekile.
Ubhubhane lwakamuva luqhube isidingo sokuzwela okukhulu nokunemba kwezinzwa ze-NTC ngokuqina kwesikhathi eside. Umhloli omusha wegciwane unezidingo eziqinile zokulawula izinga lokushisa ukuqinisekisa ukusabela okungaguquki phakathi kwesampula ne-realent. I-SmartWatch ibuye ihlanganiswe nohlelo lokuhlola izinga lokushisa ukuxwayisa ngezifo ezingaba khona.
