Kutentha kukana
Zamankhwala, zamagetsi, mafakitale, kuwerengera kutentha, kuwerengera kukana ndi zida zina zotentha kwambiri zimagwiritsidwa ntchito kwambiri.
Mfundo yogwira ntchito
PT100 ndi platinamu thermistor, kukana kwake kudzasintha ndi kusintha kwa kutentha.100 pambuyo Pt zikutanthauza kuti kukana kwake ndi 100 ohm pa 0 ℃ ndi 138.5 ohm pa 100 ℃.Mfundo yake yamakampani: pamene PT100 ili pa 0 ℃, mtengo wake wokana ndi 100 ohm, mtengo wake wokana udzauka ndi kutentha, ndipo mtengo wake wokana udzawonjezeka mofulumira.

Chigawo
Zodziwika bwino za kutentha kwa pt1oo zimaphatikizapo zinthu za ceramic, zida zamagalasi ndi zida za mica.Amapangidwa ndi mawaya a platinamu pamapangidwe a ceramic, chimango chagalasi ndi chimango cha mica motsatana, kenako ndikukonzedwa ndi njira zovuta.
Filimu yopyapyala kukana kwa platinamu
Kanema wopyapyala wa platinamu resistor: platinamu imathiridwa pa ceramic substrate ndi vacuum deposition ukadaulo wafilimu woonda.Makulidwe a filimuyo ndi ochepera 2 μ M. the Ni (kapena PD) waya wotsogolera amakhazikika ndi zinthu zamagalasi, ndipo filimu yopyapyala imapangidwa ndi laser resistance modulation.
