Zeru Kurwanya imbaraga Agaciro RT (ω)
RT yerekeza ku gaciro kirwanya gupimwa n'ubushyuhe bwagenwe T ukoresheje imbaraga zapimwe zitera impinduka zidasanzwe mu gaciro irwanya ugereranije n'ikosa ryose rikoreshwa.
Isano iri hagati yo kurwanya agaciro no guhindura ubushyuhe bwibice bya elegitoroniki ni ibi bikurikira:
RT = RN Expb (1 / T - 1 / TN)
RT: NTC TheRmistor irwanya ubushyuhe t (k).
Rn: NTC Ubushyuhe bwo kurwanya ubushyuhe bwa TN (k).
T: ubushyuhe bwihariye (k).
B: Guhora muri NTC TheRmistator, uzwi kandi nkibintu byo kwiyumvisha umutwe.
EXP: Exponent ishingiye kumibare isanzwe e (E = 2.71828 ...).
Umubano ugereranya kandi ufite urwego rwukuri gusa murwego ruto rwubushyuhe tn cyangwa kurwanywa rn, kubera ko ibikoresho bihoraho b ubwabyo imikorere yubushyuhe T.
Impanuro zeru zo kurwanya r25 (ω)
Ukurikije ibipimo byigihugu, Agaciro kaburiwe kaburimwe kaburirwa ni agaciro kagabanijwe R25 yapimwe na NTC TheRmustor ku bushyuhe bwa 25 ℃. Agaciro ko kurwanya nigiciro cyo kurwanya nominal kirwanya Thermistor ya NTC. Mubisanzwe byavuzwe ntc thermustor uburyo agaciro karwamira, bivuga kandi agaciro.
Ibikoresho bihoraho (Ubushyuhe bwo kwiyumvisha amakuru) b agaciro (k)
B indangagaciro zisobanuwe nka:
RT1: Zeru Kurwanya imbaraga ku bushyuhe T1 (K).
RT2: Agaciro ka Zeru Zeru Kubushyuhe T2 (K).
T1, T2: Ubushyuhe bubiri (K).
Kuri NTC The Conmistors, B agaciro kava kuri 2000k kugeza 6000k.
Zeru Kurwanya Ubushyuhe Ubushyuhe (αt)
Ikigereranyo cyimpinduka ugereranije muri zeru-imbaraga za NTC Thermistor ku bushyuhe bwihariye kugeza kumiterere yubushyuhe butera impinduka.
αt: Zeru Kurwanya Ubushyuhe Ubushyuhe Kubushyuhe T (k).
RT: Zeru Kurwanya imbaraga ku bushyuhe t (k).
T: ubushyuhe (T).
B: Guhaza ibintu.
Gutandukanya Coefficient (Δ)
Ku bushyuhe bwihariye budasanzwe, guhuza amacakubiri bya NTC ni igipimo cyimbaraga cyashutswe mu kurwanya ubushyuhe bujyanye n'ubushyuhe bujyanye no kumurwanya.
Δ: Coefficient yo gutandukana ya NTC TheRmustor, (MW / K).
△ P: Imbaraga zakoreshejwe na NTC TheRmustor (MW).
△ T: NTC TheRmustor akoresha imbaraga △ p, guhindura ubushyuhe bukwirakwira mumubiri wo kurwanya (k).
Ubuhe bwiza burigihe buhoraho bwibigize elegitoroniki (τ)
Ku miterere ya zeru, iyo ubushyuhe buhinduka mu buryo butunguranye, ubushyuhe bwa Thermistar buhindura igihe gisabwa kuri 63.2% yubushyuhe bubiri bwambere. Igihe cyagati gihoraho ninganiye kubushobozi bwubushyuhe bwa NTC Thermister na ugereranije muburyo butandukanye bwo gutandukana.
τ: Igihe cy'ubushyuhe buri gihe (s).
C: Ubutunzi bwa NTC TheRmustor.
Δ: Coefficial ikubiyemo NTC TheRmustor.
Powed Power PN
Imbaraga zemewe zamashanyarazi muri thermistor mugukomeza imikorere yigihe kinini mubikorwa bya tekiniki. Muri izi mbaraga, ubushyuhe bwumubiri ntiburenga ubushyuhe ntarengwa bwo gukora.
Ubushyuhe ntarengwaTmax: Ubushyuhe ntarengwa bwa Thermister bushobora gukora ubudahwema igihe kirekire munsi ya tekiniki. Ni ukuvuga, t0- ubushyuhe bwibidukikije.
Ibice bya elegitoronike bipima imbaraga PM
Ku bushyuhe bwagenwe, agaciro kirwanya umubiri wo kurwanya utwaje ibipimo ubu birashobora kwirengagizwa bijyanye nikosa ryuzuye. Muri rusange harasabwa impinduka agaciro kagaciro kurenza 0.1%.
