NTC Thermistor lokushisa sensor imigomo yobuchwepheshe

I-Zero Power Ukumelana ne-Rt (ω)

I-RT ibhekisela ngenani lokumelana elinganiselwe ekushiseni okucacisiwe t Kusetshenziswa amandla alinganisiwe abangela ushintsho olungathandeki enanini lokumelana elihlobene nephutha lokulinganisa eliphelele elihlobene nephutha lokulinganisa eliphelele

Ubudlelwano phakathi kwenani lokumelana nokuguqulwa kokushisa kwezinto ze-elekthronikhi kungokulandelayo:

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

I-RT: Ukumelana nokushisa kwe-NTC ku-Temperature T (K).

I-RN: Ukumelana ne-Thermistor nge-NTRMIRTOR ekushiseni okulinganiselwe TN (K).

I-T: Ukushisa okucacisiwe (k).

B: Material Intermistor ye-NTC, eyaziwa nangokuthi i-Thermal Sensitivity Index.

Exp: I-Exponent ngokususelwa kwinombolo yemvelo e (e = 2.71828 ...).

Ubudlelwano bunamandla futhi bunokunemba okulinganiselwe kuphela ngaphakathi kohlu olulinganiselwe lwamazinga okushisa alinganiselwe i-TN noma ukumelana okulinganiselwe i-RN, ngoba izinto ezisetshenziswayo ze-RN ngokwazo zingumsebenzi wokushisa T.

Kukalwe ukumelana namandla e-zero u-R25 (ω)

Ngokwe-National Standard, inani le-zero power ukumelana namandla yinani lokumelana no-R25 elinganiswa ngu-NTC Thermistor kumazinga okushisa angu-25 ℃. Leli veli yokumelana yinani lokumelana ne-NTC Thermistor. Imvamisa kuthiwa yi-NTC Thermistor inani elingakanani lokumelana nokumelana, futhi libhekisela kunani.

I-Material Green (Thermal Sensitivity Index) B Inani le-B Inani (K)

Amanani e-B achazwa ngokuthi:

I-RT1: I-Zero Power Ukumelana Nezinga lokushisa T1 (K).

Inani le-RT2: Inani lokumelana namandla e-zero ku-Temperature T2 (K).

I-T1, T2: amazinga okushisa amabili acacisiwe (k).

Ngezinkulungwane ezijwayelekile ze-NTC, inani le-B Inani lisuka ku-2000k liye ku-6000k.

I-Zero Power Ukumelana Namandla Okungafanele (αt)

Isilinganiso sokushintshwa kwesihlobo ku-zero-amandla ukumelana namandla e-NTC Thermistor endaweni yokushisa ecacisiwe ekushintsheni kwezinga lokushisa okubangela ushintsho.

I-αt: I-Zero Power Ukumelana nokushisa okulinganiselwe ekushiseni T (K).

I-RT: Inani lokumelana namandla e-Zero ku-Temperature T (K).

T: lokushisa (t).

B: Indwangu njalo.

I-Dissipation coeffnty (Δ)

Ekushiseni okucacisiwe okucacisiwe, i-coefficor ye-NTC Thermistor iyisilinganiso samandla ahlakazwa ku-Resistor ngokushintsha kokushisa okuhambisanayo komphikisi.

Δ: I-Dissipation Coeffred ye-NTC Thermistor, (MW / K).

△ P: Amandla asetshenziswa yi-NTC Thermistor (MW).

△ I: I-NTC Thermistor isebenzisa amandla △ p, ukuguqulwa kokushisa okuhambisanayo komzimba wokumelana (k).

Isikhathi esishisayo njalo sezakhi ze-elekthronikhi (i-ven)

Ngaphansi kwamandla ka-zero Isikhathi esishisayo sihlala silingana namandla okushisa we-NTC Thermistor futhi alingana nabantu abahle abahlelekile.

I-ENTER: Isikhathi se-Thermal njalo (s) njalo.

C: Amandla okushisa we-NTC Thermistor.

Δ: I-Disfipation Coeffred ye-NTC Thermistor.

Amandla alinganiselwe PN

Ukusetshenziswa kwamandla okuvumelekile kwe-thermistor ekusebenzeni okuqhubekayo isikhathi eside ngaphansi kwezimo zobuchwepheshe ezicacisiwe. Ngaphansi kwalawo mandla, izinga lokushisa lomzimba lokumelana alidluli amazinga okushisa aphezulu okusebenza.

Ukushisa okusebenzayo okuphezuluTmax: Izinga lokushisa eliphakeme lapho i-thermistor ingasebenza khona ngokuqhubekayo isikhathi eside ngaphansi kwezimo zobuchwepheshe ezicacisiwe. Okungukuthi, ukushisa kwe-t0.

Izingxenye ze-elekthronikhi zilinganisa amandla pm

Ekushiseni okucacisiwe okucacisiwe, inani lokumelana lokuphikiswa komzimba okufudumele ngokulinganisa kwamanje kunganakwa maqondana nephutha lokulinganisa eliphelele. Ngokuvamile kudingeke ukuthi ushintsho lwenani lokumelana lukhulu kune-0,1%.
