Kodi Pt100 imagwira bwanji ntchito?

Pt100ndi njira yotentha yolimbana ndi mfundo yake yogwira ntchito yogwira ntchito imakhazikitsidwa chifukwa cha kusintha kwa wotsutsa kukana ndi kutentha. PT100 imapangidwa ndi platinamu yoyenerera ndipo ili ndi bata wabwino komanso mzere, motero amagwiritsidwa ntchito kwambiri pakukula kutentha. Pa zero digiri Celsius, mtengo wokana za PT100 ndi 100 ohms. Pamene kutentha kumawonjezeka kapena kuchepa, kukana kwake kumawonjezeka kapena kumatsika moyenerera. Mwa kuyeza mtengo wogwirizana wa PT100, kutentha kwa chilengedwe kumatha kuwerengedwa molondola.
Sensor ya PT100 ikayamba kuyenda mosalekeza, mphamvu yake yamagetsi ndiyofanana ndikusintha kutentha, motero kutentha kumatha kuyerekezera mosapita m'mbali ndikuyeza magetsi.
