Nigute sensor ya PT100 ikora?

PT100ni ubushyuhe bwo kurwanya ubushyuhe amahame yimikorere ashingiye kumihindagurikire yabatwara hamwe nubushyuhe. PT100 ikozwe muri platine yuzuye kandi ifite ituze ryiza kandi iringaniye, bityo ikoreshwa cyane mugupima ubushyuhe. Kuri dogere selisiyusi, agaciro ko guhangana na PT100 ni 100 oms. Nkuko ubushyuhe bwiyongera cyangwa bugabanuka, kurwanya kwayo kwiyongera cyangwa kugabanuka uko bikwiye. Mugupima agaciro ka PT100, ubushyuhe bwibidukikije burashobora kubarwa neza.
Iyo sensor ya PT100 ihora itemba, isohoka rya voltage iringaniza nihinduka ryubushyuhe, bityo ubushyuhe burashobora gupimwa muburyo butaziguye no gupima voltage. Ubu buryo bwo gupima bwitwa "voltage isohoka ubwoko" gupima ubushyuhe. Ubundi buryo busanzwe bwo gupima ni "ubwoko bwo guhangana nubwoko", bubara ubushyuhe mugupima agaciro ka PT100. Hatitawe kuburyo bwakoreshejwe, sensor ya PT100 itanga ibipimo byukuri byubushyuhe kandi ikoreshwa cyane muburyo butandukanye bwo kugenzura ubushyuhe no gukurikirana porogaramu.
Muri rusange, sensor ya PT100 ikoresha ihame ryo kurwanya imiyoboro ihindagurika hamwe nubushyuhe kugirango bapime neza ubushyuhe mugupima ubukana cyangwa voltage, bitanga ibisubizo bihanitse byo gupima ubushyuhe bwo kugenzura ubushyuhe butandukanye no kugenzura porogaramu.
