I-NTC yeRmermistor yeSomer

Ixabiso lamandla amandla e-Zero rt (ω)

I-RT ibhekisa kwixabiso lokuchasana nokulinganisa ubushushu obuchaziweyo t usebenzisa amandla alinganayo esebenzisa utshintsho olungakhathalelwanga kwixabiso lokunganyangeki.

Unxibelelwano phakathi kwexabiso lokuxhathisa kunye nokutshintsha kobushushu bezinto ze-elektroniki zezi zilandelayo:

I-RT = I-RN Extb (1 / T-1 / TN)

I-RT: I-NTC ye-TRMITHRECROST kwiqondo lokushisa i (k).

I-RN: I-NTC ye-thermistor yokunganyangeki kwi-tn (k).

T: Iqondo lobushushu (k).

B: Izinto ezibonakalayo ze-thermistor ye-NTC, ekwabizwa ngokuba yiNdawo yeVermal Veeval.

Exp: Exponet esekwe kwinombolo yendalo e (e = 2.71828 ...).

Ubudlelwane butsha kwaye bunomgangatho wokuchaneka ngaphakathi kuluhlu olulinganiselweyo lweqondo lobushushu i-TN okanye i-RN Ukuhlala i-RN, kuba i-BSOSTARY B isebenza ngeqondo lobushushu t.

I-R25 (ω)

Ngokutsho komgangatho kazwelonke, i-ROATION yexabiso lokuchasana namandla okumelana nexabiso le-R25 elilinganiswe yi-thermistor ye-NTC kwiqondo lokushisa le-25 ℃. Ixabiso lokuchasana lixabiso elithi Philayo le-NTC TRMISTOR. Ihlala ithe i-thermistor ye-NTC ukuba ixabisa kakhulu ixabiso, likwabhekisa kwixabiso.

Izinto ezibonakalayo (Isalathiso semvakalelo ye-thermal) Ixabiso le-B (k)

Ixabiso le-B lichazwa njenge:

RT1: Ukuxhathisa kwamandla amandla kwiqondo lokushisa i-T1 (k).

I-RT2: Ixabiso lokuxhathisa kwamandla kumandla kwiqondo lokushisa i-T2 (k).

T1, T2: Amaqondo amabini achaziweyo (k).

Kwi-thermishators eqhelekileyo ye-NTC, iXabiso le-B livela kwi-2000k ukuya kwi-6000k.

I-Zero Amandla Amandla okuxhathisa i-ICORD (αt)

Umyinge wotshintsho kwi-zero-Ukuxhathisa i-thermistor ye-NTC kwiqondo lokushisa elichaziweyo kuguquko lobushushu olunokubangela utshintsho.

I-αt: Iqondo lokuchasana namandla okuxhathisa kwamandla e-IRORDES kwiqondo lobushushu T (k).

I-RT: Ixabiso lamandla amandla okuxhathisa ngamandla kwi-t (k).

T: Iqondo lokushisa (t).

B: Izinto zihlala zihlala.

Ukungasebenzi kakuhle (δ)

Kwibubuso alinganayo, ukusebenzela ukusebenza kwe-NTC thermistor ngumyinge wamandla owenziweyo kwinguqulelo yokuhlawula ubushushu obuhambelana nokuhlawula.

δ: Ukubekwa i-HOPIPONICONARDORD ye-NTC ye-thermistor, (mw / k).

P: P: UKHUSELEKO LWE-NTC TRMISTOR (MW).

△ T: I-NTC i-TRMPICTOR Ifaka amandla e-△ P, utshintsho lobushushu ohambelana nomzimba (k).

Ixesha le-shirmal lihlala lihleli kwizixhobo ze-elektroniki (τ)

Ngaphantsi kweemeko zamandla e-zero, xa ubushushu obuhamba ngokukhawuleza, ubushushu be-thermistor butshintsha ixesha elifunekayo kwi-63.2% ye-oversicary yokuqala yobushushu. Ixesha le-thermal lihlala lihambelana nobushushu be-thermistor ye-NTC kunye nokulingana ngokuchaseneyo nokungasebenzi kwayo.

τ: Ixesha le-shirmal lihlala (s).

C: Umthamo wobushushu we-thermistor.

δ: Ukungasebenzi kakuhle kwe-thermistor ye-NTC.

Amandla aMandla ayo

Ukusetyenziswa kwamandla okuvunyiweyo komthetho we-thermistor ngokusebenza okuqhubekayo ixesha elide phantsi kweemeko ezichaziweyo zobugcisa. Phantsi kwalo mandla, amaqondo obushushu omzimba axhathise akagqithi kubushushu balo olona nyango luphezulu.

Ubushushu obuninzi bokusebenzaI-tmax: Ubushushu obuphezulu apho i-thermistor inokusebenza khona ngokuqhubekayo ixesha elide phantsi kweemeko ezichaziweyo zobugcisa. Oko kukuthi, iqondo lobushushu le-t0.

Izinto ze-elektroniki zilinganisa i-PM PM

Kubushushu obumiselweyo, ixabiso lokuchasana nomzimba wokuxhathisa ovutha ngumlinganiso wangoku unokungahoywa ngokunxulumene nempazamo yomgangatho. Ifuneka ngokubanzi ukuba ixabiso lokuchasana nexabiso lingaphezulu kwe-0.1%.
