Ib qhov ntsuas kub tsis zoo (NTC) yog hais txog cov khoom uas muaj kev poob qis hauv hluav taws xob thaum lawv qhov kub thiab txias nce. Cov ntaub ntawv uas muaj txiaj ntsig engineering siv feem ntau qhia qhov txo qis nrog qhov kub thiab txias, piv txwv li qis coefficient.
Puas insulators muaj qhov tsis zoo ntawm qhov kub thiab txias?
Nyob rau hauv cov khoom siv uas qhov kev tiv thaiv nce ntxiv nrog qhov nce hauv qhov kub thiab txias, cov khoom tau hais tias muaj qhov zoo ntawm qhov kub thiab txias..
Qhov twg ntawm cov ntsuas kub ntsuas qhov ntsuas kub tsis zoo?
1. Negative Temperature Coefficient (NTC) thermistor. Lub thermistor yog ib qho thermally rhiab heev resistor uas nthuav tawm ib qho txuas ntxiv, me me, kev hloov pauv hauv qhov tsis kam cuam tshuam nrog kev hloov pauv hauv qhov kub thiab txias. NTC thermistor muab kev tiv thaiv siab dua ntawm qhov kub thiab txias.
Tus nqi ntsuas kub puas tuaj yeem tsis zoo?
Ib qhov ntsuas kub tsis zoo (NTC) yog hais txog cov ntaub ntawv uas muaj kev poob qis hauv hluav taws xob thaum lawv qhov kub thiab txias. … Qhov coefficient qis dua, qhov txo qis hauv hluav taws xob ntau dua rau qhov ntsuas kub nce ntxiv.
Vim li cas cov thermistor muaj qhov kub tsis zoocoefficients?
Muaj ob hom thermistor: Tsis Zoo Kub Coefficient (NTC) thiab Qhov Zoo Kub Kub Coefficient (PTC). Nrog NTC thermistor, thaum qhov kub nce, tsis kam txo. Conversely, thaum kub txo, kuj nce. Hom thermistor no yog siv ntau tshaj plaws.
